Prevention and maintenance of pests and diseases of garden plants in spring
After the beginning of spring, the temperature rises, the air humidity increases, and the pests and diseases of garden plants increase, but the overall incidence is relatively mild. The main pests are red palm weevils, aphids, whitefly, blood tree leaf mites, celestial bulls, termites, Egyptian blowing mites, Kao's white shield borer, mulberry white borer, peach pteris, duck-footed tree star room lice, etc.; the main diseases are powdery mildew, banyan tree coal pollution disease, anthrax and so on. Since April, temperatures have continued to rise, the air is humid and foggy, the rainfall is increasing, and the occurrence of garden plant pests and diseases tends to increase. April is a key period for the control of pests and diseases of garden plants.
1. Transplanting plants
Spring is the best time to transplant evergreen broad-leaved tree species.
2. Fertilize in spring
Spring and autumn are the most important fertilization seasons for garden plants, this season fertilization can be selected from compound fertilizers with high nitrogen content, urea, etc., with "Drifting Green No. 8 Fertilizer" with "Drifting Green Fertilization Gun" root fertilization, or spraying the entire plant leaves.
Third, the main pests and diseases are:
Spring is suitable for the occurrence of insect pests, some sucking garden insect pests will continue to harm, other pests of the first generation have occurred, we should seize the opportunity to focus on prevention and control.
1, the United States white moth: In recent years, the American white moth is seriously harmful, and many regions have begun to carry out the prevention and control of white moth in April. Adult White Moths in the United States can still be seen feathering and spawning in late May and early June. At present, a large number of larvae hatch and form a nascent mesh curtain, and the age of insects is mostly 1-2 years old. At this stage, the "Moth Gang" should be sprayed for control, and combined with manual cutting of the net curtain to kill larvae control.
2. Inchworm: At the end of May and the beginning of June, a generation of inchworm larvae has reached 3 years old and is about to begin to enter the gluttony period. At this stage, the "Moth Gang" can still be sprayed for control.
3, leaf-eating pests: the leaf-eating pests that are endangering are: Yang Fanzhou moth, willow poison moth, moth, dancing poison moth, light sword night moth, boxwood silk borer, etc. should pay attention to the inspection and control with "green moth gang".
4. Grasshopper: According to the investigation, the female adult grasshopper has begun to lay eggs in the tree in early June to find a summer and wintering place. However, some insect bodies continue to be harmful on the branches. In addition to spraying "floating green silkworm stop" to control female insect bodies during this period, manpower should be organized to remove female insect bodies that lay eggs from the lower tree and the upper wall into the soil to reduce the overwintering base. In this period, it is also possible to trap the grass and burn it after all of it is planted.
5, ziwei velvet beetle: the purple vili fly that occurs on the pomegranate and the purple weed, at the egg stage, a large number of eggs are in the oocyst, and the eggs can hatch at the end of May and the beginning of June. It can be manually scraped off the egg sac for prevention and control, and can also be sprayed with "floating green bug stop" prevention and control.
6, locust solid borer, shaliyuan brown ball bug, wei spear arrow tip shield bug, tumor jian large ball bug, locust flower ball bug and other insects: the beginning of June are the first incubation period of the above insects, should seize the time to check, once you see the branches and leaves on the hatching nymph crawling, you can spray control, spray "floating green bug stop" control.
7, wood lice: the four kinds of wood lice that often occur, namely acacia wood lice, saponaria wood lice, green paulownia wood lice, pot shelf wood lice are all occurring in the early June, should be sprayed "Ya lice horse" or "lice stop" for prevention and control. The prevention and control of the insect should be based on the principle of early treatment and small treatment, otherwise it will cause deciduous coal pollution in the later stage, affect the landscape, and environmental pollution.
8, aphids: the aphids that occur on the flower shrubs in June, the more serious ones are peach white aphids, meadowsweet aphids, cotton aphids, and some peach tumor aphids occur. The more serious occurrences on trees are Luan polymorphic hair aphid, willow black hair aphid, poplar hair aphid, locust aphid, and individual maple polymorphic hairy aphid are also very serious. We should pay close attention to spraying "ya lice horses" for prevention and control.
9, red spider: hawthorn leaf mite, the mite in the Xifu begonia, peach, purple leaf plum and other flower shrubs are seriously harmful. It should be killed at the end of May and the beginning of June, otherwise it will cause the leaves to fall. In recent years, red spiders have occurred seriously on trees, and the trees that have occurred red spiders are: Tsubaki, National Locust, Acacia, Ash, Silk Cotton, Neem, Mulberry, Elm, Willow, Poplar. Spray "Floating Green Blessings" for prevention and control.
10, bare shoulder star tianniu: in late May, the bare shoulder star tianniu will begin to feather, once found to have a new feathering hole, the drug control of adult insects can begin. Spray green "Tree Worm Kang" or "Ya Lice Horse" for control. At present, the larvae that continue to be endangered should be controlled by injecting "Tree Worm Kang No. 6".
11. Small-lined horn wood beetle moth: There will be adult feathering in early June, and there are still some larvae in the xylem hazard, and should be injected with "Tree Worm Kang No. 6" agent for control.
12. Ailanthus tunnel elephant: Ailanthus furrow orbital elephant larval hazard, can be controlled by injection. Adults can be controlled by spraying "ya lice horses".
13. Grub larvae and adult scarab beetles: mainly harmful to the moon season, Xi Meili, Ziwei, Large-leaved Ziwei, Thorn Tree, etc. Adults bite leaves, buds, and petals in a absent manner, and in severe cases, they eat the leaves, leaving only the veins or eating them. Most species occur in one generation a year, with adults in March-September and may-July. Adults have a suspended death nature, and when alarmed, they fly away or fall. Adults lay their eggs in the soil. Hatched larvae (grubs) feed on the roots of plants in the soil. Timely use of "Ground Cluster No. 1" for prevention and control.
14. Gray and white silkworm moth: mainly harms yellow fig, fine-leaved fig, weeping fig, large-leaved fig, alpine fig, bodhi fig, etc. Harmful to the leaves of fig plants, with larvae biting the leaves and young leaves of plants, insect pests often occur, seriously affecting tree growth and ornamentation. The hatching larvae have the habit of feeding on the egg shell, hatching for tens of minutes and then begin to eat the leaves, eating the leaves into small holes, the 2-3 year larvae eat the leaf flesh, so that the leaves are left with a network of veins, and the 4-5 year larvae encroach inward from the leaf edge, resulting in lack of moments, and even the whole leaf is eaten. Mature larvae pupate on the back of leaves, branches at forks or on cracks in the bark, and are controlled with "moth gangs".
15. Ficus permeable winged moth: mainly harms weeping fig, yellow fig, fine-leaved fig, large-leaved fig, etc. It harms the leaves of ficus plants, eating the leaves with larvae, and affecting tree growth and ornamentation when the insect infestation occurs severely. In South China, the annual generation occurs from 6 to 7 generations, and in South China, the larvae are harmful from April to December, and the harm is serious from May to August. The larvae feed on the leaf flesh, leaving the leaves with a reticulated vein. The old mature larvae pupate on the foliar surface and are controlled with the "Moth Gang".
16. Twill noctus moth: mainly harms fine-leaved knotweed, false sword grass, large-leaf oil grass, small-leaf oil grass, etc. Larvae bite the leaves, stems, and roots of grasses, often causing clumps of death. Hazards occur in South China from May to October every year, and serious hazards occur from June to August. The heavily damaged lawn is dead, and a large amount of insect feces is seen under the grass, where a large number of larvae can be found at the rhizosphere. The larvae pupate in shallow soil near the rhizosphere and are controlled with the "Moth Gang".
17, red palm weevil: mainly harmful to oil palm, coconut, date palm, bottle coconut, date palm and so on. Larvae and adults are used to drill into the trunk and petiole of the borer tree, and to feed on soft tissues, which can lead to plant death in severe cases. From April to December, both adult and larvae were harmed, and the more concentrated periods of adult insect emergence were In May and November. When the larvae eat the growth point of the tree, the initial heart leaf is incomplete, or the growth point rots, and finally the plant dies, and the "tree worm Kang" is used for control.
17. Leafhoppers: mainly harm safflower (Fuso), kapok, peach blossoms, bamboo, autumn maple, etc. Adults and nymphs suck up plant sap, and the affected leaves appear small white spots, and in severe cases, the whole leaves are whitish, and some leaves are wrinkled and curled. Affects plant development and growth. This insect can also transmit infectious diseases. May to June, September to October every year is the peak period of occurrence, with "Ya lice horse" for prevention and control.
Prevention and maintenance of pests and diseases of garden plants in summer
1. Do a good job in drainage and drought resistance
Strengthen drainage in places during the rainy season, you can spray "drifting green kang" after the rainy season to prevent diseases, strengthen watering in arid and high temperature areas, avoid high temperatures when watering, spray more foliar surfaces, and follow the principle of "dry and thorough watering" for root watering.
Ginkgo biloba, persimmon tree, cherry blossom, clove, peach, acacia, elm plum, five-pointed maple, locust, cedar these 10 kinds of trees are the most water-free, strengthen the drainage and anti-root rot of these trees (especially newly transplanted trees), you can sprinkle "heel construction" around the trees before and after the rainy season for prevention and control.
2. Strengthen the maintenance of lawns and flowers
Summer is a high incidence of lawn diseases and insect pests, it is easy to form dry spots, macula, overall yellowing, etc., with "green health" + "soil baby" for irrigation, can make the lawn in 5-10 days quickly restore the green period. In key areas, after a long period of rain or pruning, please water the "drifting green health" + "soil baby" for disease prevention and rejuvenation. Seasonal flowers are sprayed intensively, and the leaves can be sprayed twice a day, and the root watering follows the principle of "dry and thorough watering".
3. Remove the wrapper
For the grass rope, linen and other wrapping on our newly transplanted trees, we must remove them as soon as possible to avoid burning the tree body. Where the shade net is built, the shade net cannot be directly placed on the tree, and it is built at a place where the tree body is more than 50 cm.
4. Pruning and reinforcement
The pruning of summer lawn should be appropriately increased to the height of stubble retention of 2-3 cm, can not be trimmed too low, pruning too low can easily cause the dry grass layer leakage, affecting the appearance.
Before the rainy season, the canopy will be too tall, sparse and truncated at the right time, which can enhance the wind resistance and cooperate with overhead line pruning. During the flood season, the trees that have been tilted upside down should be straightened in time, and they must be replanted as soon as possible. If necessary, support should be set up.
5. Fertilization summer less fertilizer, especially less nitrogen fertilizer, can use "leaf force" for re-strengthening spraying or watering.
6. The survival rate of replanted trees such as pine cypress, palm family and bamboo is high in the rainy season.
The main pests and diseases of summer garden plants are:
1, camphor nest borer: normal climate year in our city in mid-to-late June appeared the first generation of larvae, August appeared in the second generation of larvae, camphor nest borer has a generational overlap phenomenon, 6-10 months in the nest has the harm of different ages of larvae, is currently the first generation of larval harm period, but also the best time for prevention and control. Control with "Moth Gang".
2, mites: every year camphor, peach, safflower sorrel grass, osmanthus flowers, moon season and other plants have red spider hazards, most of the plants on the mites and eggs exist at the same time. The insect is prone to outbreaks in high temperature and dry seasons, and the red spider causes the leaves to lose green and brown after feeding, which not only affects the tree potential but also affects the landscape. Before the arrival of the high temperature and heat, use the "Floating Green Full Blessing" spray, and try to spray both sides of the blade when spraying.
3, yellow thorn moth: also known as itchy pepper, poisonous caterpillar and so on. The hazard period is from mid-to-late June to mid-to-late July and from mid-to-late August to September; the larvae generally mature in October and look for suitable branches to overwinter. Control with "Moth Gang".
4, the shell insects: in July and August all kinds of insects continued to harm, in recent years, more and more earthworms have occurred, the situation is grim. Can be sprayed "floating green bug stop" + "Ya lice horse" prevention and control.
5. Grub adult scarab beetle: bite leaves, buds, petals are absent, severe when the leaves are eaten, leaving only leaf veins or eating out. May-July peak period. Adults have a suspended death nature, and when alarmed, they fly away or fall. Adults lay their eggs in the soil. Hatched larvae (grubs) feed on the roots of plants in the soil. Timely control of larvae and adults with "Ground Cluster No. 1".
6. Twill noctus moth: mainly harms fine-leaved knotweed, false sword grass, large-leaf oil grass, small-leaf oil grass, etc. Larvae bite the leaves, stems, and roots of grasses, often causing clumps of death. Hazards occur in South China from May to October every year, and serious hazards occur from June to August. The heavily damaged lawn is dead, and a large amount of insect feces is seen under the grass, where a large number of larvae can be found at the rhizosphere. The larvae pupate in shallow soil near the rhizosphere and are controlled with the "Moth Gang".
7, Chongyang wood spotted moth: this year the insect broke out again, the second generation of larvae in July is not neat, most of them are close to old maturity, that is, spit silk drooping, under the tree cocoon, the beginning of the year should be tightened to prevent the third and fourth generations of larvae from more serious harm. Control with "Moth Gang".
8. Yangzhou moth: A generation of larvae generally begins to occur in mid-to-late June, and July is also its main harm period. Control with "Moth Gang".
9, net bugs: the harm period is from April to October, July and August high temperature drying hazards will continue to aggravate may cause its outbreak, coupled with high temperature, the impact on flowers and trees is greater. Prevention and control with "bush without a trace".
10. Tianniu: In early July, most of them are 3 pre-larvae, and the drill moth site is shallow, and the control is relatively easy. Control with "Tree Worm Kang".
11. Golden Leaf Privet Leaf Jumping Beetle: The second generation of larvae has been submerged as a pest, but the first generation of adults is still active, and the larvae and adults should be controlled at the beginning of the month, and the third generation of larvae may appear around the end of July. Prevention and control with "volume industry".
12. Yellow poplar silk borer: In previous years, most of the second generation of larvae entered the peak stage at the end of July. Control with the "Moth Gang".
13. Leaf diseases and lawn diseases
After entering the plum, the rainfall will increase significantly, a variety of plant and lawn diseases will be aggravated to varying degrees, the middle and late part of this month will enter the high temperature season, plant resistance will be reduced, coupled with weather and human factors to promote the spread of germs, so plant leaf diseases and lawn diseases in the high temperature season "easy to occur, easy to spread, easy to aggravate.". Golden leaf Privet, Phnom Penh boxwood, large-leaf boxwood, ginkgo biloba, star anise gold plate, etc. will continue to have leaf spot disease, anthrax, leaf blight, etc.; cherry blossoms, peaches, begonias, beech and other leaf perforation disease, moon season black spot disease, purple weed, large leaf boxwood and other powdery mildew disease will continue to aggravate and spread; lawn will also have rust, powdery mildew, powdery mildew, brown spot disease, gray mold, etc. occur in succession, the rainy season and july and August high temperature season should pay special attention to the prevention and control of these diseases, prevention and control focus should be on improving conservation measures, Supplemented with appropriate medications for prevention or control.
Control and maintenance of pests and diseases of garden plants in autumn
Garden plants "three points of planting, seven points of maintenance", autumn temperature gradually decreased, the season is the season of plant storage nutrients, but also the peak period of disease and pest outbreak, at this stage to do a good job in the planting, fertilizer, water, grass, disease, insects, shear seven aspects of the maintenance and management of management.
1. Plant transplanting
1. Autumn is the best season for transplanting broad-leaved deciduous tree species, and it is best to transplant the leaves just after the leaves are shed.
2, autumn windy, the temperature gradually drops, autumn tree transplanting to do a good job of water retention and insulation, is conducive to the survival of trees.
3, autumn can transplant evergreen broad-leaved tree species and palm tree species, but not the best season, if you want to rush the construction period, please do a good job in the details of transplanting, improve the survival rate of transplanting.
2. Plant pruning
Generally deciduous plants are carried out after defoliation in late autumn to before germination in the following year; evergreen conifers are carried out in early autumn; evergreen broad-leaved plants are carried out in spring; and tree species with injury should avoid the injury flow period. Prune frequently after shaping to maintain the tree shape.
(1) Pruning of natural hedges (2) Pruning of whole forms of hedges
(3) Pattern ribbon trimming (4) Plant shape trimming
(5) After pruning, spray 1000 times the green leaf force / 1000 times of sukang + 1000 times of lukang sterilization and disinfection, restore growth.
Third, fertilize
Autumn is the season for garden plants to store nutrients, and doing a good job of fertilization in autumn can ensure the overall growth of plants in the coming year. This season can be spread throughout the area with "Floating Green No. 6 Fertilizer".
1. Fertilization in this season should be mainly P and K, supplemented by N fertilizer.
2. Appropriate organic fertilizer can be applied in this season, which is conducive to the wintering of plants and the reserve of plant nutrients.
3. Autumn is the most important fertilization season of the year for cold-season grass lawns, and the autumn fertilization of warm-season grasses should not be too late, and it is recommended to carry out in early autumn.
4. Piaolu No. 6 fertilizer is an organic and inorganic compound fertilizer, which can meet the various needs of autumn fertilization. Piaolu No. 8 liquid fertilizer humic acid, potassium fulvic acid, nitrogen, phosphorus and potassium, trace elements, auxin substances, etc., instead of traditional fertilizers, can save time and labor and effort to fertilize, is the future development direction of garden plant fertilization. Piaolu No. 8 fertilizer realizes mechanized fertilization of garden plants, high safety, fast effect, no crazy growth, low labor costs, focusing on increasing the ornamental quality of plants, and the fertilizer cost is about 30% of traditional fertilizers.
Fourth, water
1, autumn windy, large amount of water loss, in accordance with the principle of "no dry watering, watering through" timely replenishment of water.
2. For the area where the underground pest grub outbreak can be watered once in late autumn.
3. In areas with serious frost damage, the antifreeze water can be watered as a whole in late autumn, and the amount of water can penetrate into the soil below about 5cm.
5. Weed control
1, autumn weed control pay attention to avoid the morning dew spray, water loss fast place can be "spray water the first day, spray the next day" to maintain soil moisture.
2. The absorption of herbicides by plants in autumn is very slow, and the effect time of herbicides is slightly slower than that of spring.
3. For street trees, nurseries and other places with weeds such as cow tendons, you can choose to spray No. 2 with floating green pieces; if there is thatch, you can choose to spray with sharp leaves.
4. For parasitic plants such as silk seeds, you can choose to spray the green silk road.
5. The following herbicides are selected for lawn weeds:
(1) Sedges weeds: use the use of floating green sand / kosha to prevent.
(2) Grass weeds: use drifting green grass to prevent and remove.
(3) Broad-leaved weeds: use fluttering green broad and wide / wide no stay No. 1 to prevent removal.
(4) Weed removal in wheat winter: use drifting green wheat to remove weeds.
(5) White three-leaf, horseshoe gold weeds: use three wooden horses to prevent removal.
6. Pest control
1, the tick insect: all kinds of insect shell insects continue to harm, the insect can be artificially transmitted, can also be spread by wind. It can be sprayed with "floating green bug stop" control, and difficult to prevent insect shell insects can be controlled with "Ya lice horse" + "floating green bug stop".
2, thorn moth: also known as itchy pepper, poisonous caterpillar and so on. The hazard period is from mid-to-late June to mid-to-late July and from mid-to-late August to September; the larvae generally mature in October and look for suitable branches to overwinter. Control with "Moth Gang".
3, camphor nest borer: the normal climate year in the middle and late June appeared the first generation of larvae, August appeared in the second generation of larvae, camphor nest borer has a generational overlap phenomenon, June to October insect nest has the harm of different ages of larvae, is currently the first generation of larval harm period, but also the best time for control. Control with "Moth Gang".
4. Twill noctus moth, lawn armyworm: Armyworm mainly harms warm-season lawns such as knotted grass and dog tooth root. 4-5 generations occur in 1 year, and it is currently in the 3-4 generations of nibbling on young stems and young leaves, inhabiting the soil surface during the day, and the harm peaks from 9 to 12 o'clock in the evening. The twill nocturnal moth mainly harms grasses such as fine-leaved knotweed, false sword grass, horseshoe tendon, large-leaf oilgrass, and small-leaf oil. Larvae bite the leaves, stems, and roots of grasses, often causing clumps of death. Control with the "Moth Gang".
5, black-edged borer moth, Venus ruler moth: the main harm to melon seed boxwood, finch tongue boxwood, large-leaved boxwood, is in the 2-3 age stage, the insect reproductive coefficient is high, short life cycle, need to pay attention to observation, with the "moth gang" timely prevention and control.
6. Ficus permeable winged poison moth: mainly harms weeping fig, yellow fig, fine-leaved fig, large-leaved fig, etc. It harms the leaves of ficus plants, eating the leaves with larvae, and affecting tree growth and ornamentation when the insect infestation occurs severely. The larvae feed on the leaf flesh, leaving the leaves with a reticulated vein. The old mature larvae pupate on the foliar surface and are controlled with the "Moth Gang".
7. Large bag moth: mainly harms economic tree species such as ginkgo biloba, cedar, fruit trees, etc., and spits silk bags to overwinter after nibbling on leaves.
8, Tianniu larvae and adult insects: larvae mainly harm the trunk, adult insects mainly nibble a variety of flowers and shrub branches, large-leaved boxwood, red maple, purple weed, heather, poplar, willow, tung, green maple, cherry blossom, peach, plum blossom, etc., is currently the peak of larval moth food, larvae can use "tree insect Kang", "tree insect Kang No. 2" or "tree insect Kang No. 6" for control, larvae adults can use "tree insect Kang" + "bush without a trace" spray control, for the control of larvae can be appropriately increased spray concentration.
9. Grub larvae and adult scarab beetles: adult insects mainly harm the moon season, Xi Meili, Ziwei, large-leaf Ziwei, Thorn Tree, etc. Adults bite leaves, buds, and petals in a absent manner, and in severe cases, they eat the leaves, leaving only the veins or eating them. Larvae (grubs) feed on the roots of plants in the soil, harming various lawns, hedges and so on. Timely use of "Ground Cong No. 1" for prevention and control.
10, aphids: aphids that occur on flower shrubs in June, the more serious ones are peach whitefly, meadowsweet aphids, cotton aphids, and some of them have peach tumor aphids. The more serious occurrences on trees are Luan polymorphic hair aphid, willow black hair aphid, poplar hair aphid, locust aphid, and individual maple polymorphic hairy aphid are also very serious. We should pay close attention to spraying "ya lice horses" for prevention and control.
11, mites: every year camphor, peach, safflower sorrel grass, osmanthus flowers, moon season and other plants have red spider hazards, most plants on the mite and eggs exist at the same time. The insect is prone to outbreaks in high temperature and dry seasons, and the red spider causes the leaves to lose green and brown after feeding. Before the arrival of the high temperature and heat, use the "Floating Green Blessing" positive and negative spray.
12. Root rot/stem rot:
Occurrence pattern: The autumn rain is long in this month, and the roots are easily infected with germs, and can be infected with the soil and rain.
Prevention and control methods: floating green heel construction / dry mei Yizhi 800 times + block heel 1000 times watering 2-3 times, 3-5 days / time.
13, dry rot, glue disease: the disease has been delayed with the decrease in temperature, but for the summer has already occurred, it is still necessary to strengthen control and prevention. Prevention and control with "cadre governance".
14, leaf diseases: with more rain in the month, the climate is warm and humid, and various leaf diseases are a small peak of outbreak. Such as powdery mildew, rust, leaf blight, leaf spot disease, coal pollution disease, branch blight, perforation disease and so on.
(1) Powdery mildew, rust: 800 times of green fen xiu'an + 800 times of leaf force spray 2-3 times, 5-7 days / time.
(2) Leaf blight, leaf spot disease: 800 times the green industry spot killing + 800 times the leaf force spray 2-3 times, 5-7 days / time.

(4) Branch blight: 600 times the green industry spot kills + 600 times the spray leaves of Quickkang, 600 times the cure of the dry beauty + 800 times the soil baby irrigates the roots 2-3 times, 5-7 days / time.
Winter garden plant pest control and maintenance
1. Transplanting trees:
1. Before entering the winter, it is the best season to plant deciduous tree species, and transplant immediately after the leaves fall, and the survival rate of transplanting is high.
2. Newly transplanted plants are required to do a good job of "cold protection and warmth".
3, winter generally do not replant plants, such as to replant, must do a good job of cold and antifreeze work, and transplant hardy varieties.
2. Winter Qingyuan:
Winter Qingyuan is an important measure for the winter maintenance of garden plants.
1. Prune dead branches and leaves.
(1) Prune off diseased insect branches, diseased and weak branches, and affect tree-shaped branches.
(2) Clean up the surrounding dead branches and dead leaves, and reduce the wintering site of diseased bacteria and insect eggs.
2. Prevention and control of germs and insect eggs.
(1) Use stone sulfur compound + heel construction + floating green oyster to stop spraying all garden plants, and control all kinds of insect eggs and bacteria such as shell insects, trunk pests, rot diseases and so on.
(2) Stone sulfur compound can not be used frequently, long-term use of diseases and insects are easy to produce resistance, use 1-2 times a year, and winter is the best time to use stone sulfur compound, stone sulfur compound if mixed with other pesticides should be "ready to use" (some pesticides can not be mixed), after the combination can not be placed for too long. The stone sulfur compound is used strictly in accordance with the concentration of use, and the concentration of use cannot be increased at will.
3. Brush the trunk white in winter.
(1) Whitening time:
Generally from mid-to-late November to early January of the following year, beyond this range does not have the real effect of whitewashing.
(2) The role of trunk whitening:
a, prevention of frost damage b, control of pests and diseases c, prevention of animal bites
Third, cold and warm:
1. Cold-proof and anti-freeze key plants
(1) Main non-freeze-resistant plant varieties: sea tree, heather, red-leaved barberry, small-leaf boxwood, begonia, honeysuckle, pearl plum, bauhinia, hydrangea, Xifu begonia, white ash, white magnolia, magnolia, camphor, whitebar pine, cedar, luan tree, pentagram, juniper cypress, big-leaf privet, mai dong, ground brocade, jade hairpin, iris, sedum, mid-spring orchid, large flower grass, Laoyu moss grass, white trifolium, wildflower combination, etc.
(2) Hardy plants in different regions, especially southern plants, are planted in the north.
(3) Plants in special areas: such as plants on the air outlet, unobstructed areas, cement paving areas, and small habitat space.
(4) Weak plants. (5) Newly planted plants for 1-2 years. (6) Partial hedges.
2. The cause of frost damage
(1) Sustained low temperature (2) Newly transplanted trees are prone to frost damage
(3) The plant itself is not frost resistant (4) The fertilizer water management is poor, and the plant growth is weak
3. Measures for the prevention of frost damage of garden plants
(1) Spray antifreeze agent:
Spraying antifreeze can effectively protect plant roots, as many young branches and part of the leaves as possible, while preventing "pouring spring cold", using "drifting green antifreeze" to spray plant leaves and stems before the cold tide comes, and for plants with serious frost damage, they can also water the roots. Drift green antifreeze has film forming agents, attractants, active substances and nutrients compounded, to put on a layer of clothing for garden plants, promote nutrient storage, increase plant stress resistance, reduce the freezing point of garden plants about 5 degrees, can maximize the protection of garden plants from frost damage. It is best to use it in 10-12 months before the arrival of winter, use 2-3 times continuously, with an interval of about 10-15 days, generally plants take the method of spraying foliage, and some non-cold-resistant plants take a combination of spraying foliage and watering roots. Spraying "floating green antifreeze" must be carried out in advance.
(2) Pour antifreeze water (3) Cover the roots (or mulch) (4) Build a wind barrier
(5) Wrap the trunk (6) Pile snow at the root:
4. Cold protection measures for different plants
(1) For lawns, grass flowers: water antifreeze water, spray antifreeze agent, and lay grass curtains when necessary for individual varieties.
(2) For hedge shrubs: watering antifreeze water, spraying antifreeze agents, it is recommended to attach mulch film to cold-tolerant varieties, crown plastic bags (spray fungicide disinfection before bagging) or tree trunks wrapped with grass ropes, thermal insulation belts and other measures.
(3) For trees: spray antifreeze and fungicide on the whole plant, wrap the trunk around the grass rope or insulated bag, or attach the mulch film to the root, cover the soil, and whiten the trunk.
5. Emergency treatment when frost damage occurs in garden plants
(1) Sokcho cold protection (2) Canopy cover (3) Smoke to create fog
6. Thawing method of frozen plants after frost damage occurs
(1) Reasonable pruning: After spring, the canopy is treated according to the principle of "picking leaves with minor injuries, pruning with minor injuries, and sawing dry with major injuries".
(2) Drug treatment: after pruning, the whole plant is sprayed with "drifting green thawing", and plants with severe frost damage can be combined with root watering, and "drifting green thawing" is one of the few products on the market that promote frost damage recovery.
(3) Timely and early watering and fertilization after spring:
With "Floating Green No. 8 fertilizer" or "leaf force" added to the sprinkler truck spraying and watering plants, watering and fertilization at the same time, to promote rapid recovery of plants, granular fertilizer effect is slow, high cost, urban large-scale fertilization there are safety hazards, it is recommended that you take "Drifting Green No. 8 fertilizer" or "leaf force" new fertilizer, save time and save money, quick effect, timely help plants recover tree potential, lift frost damage.
7. Precautions for cold protection and anti-freezing
(1) The watering of antifreeze water is determined according to the temperature change.
(2) Wrap the straw rope insulation bag, be sure to pay attention to the root part to be wrapped in place, the root part is a sensitive area of frost damage.
(3) Spray fungicide disinfection before wrapping grass rope and set plastic bags.

After the treetops stop growing after fertilization in the autumn, the root system has another growth peak. Fertilization in late autumn can induce the absorption, digestion and release of nitrogen, phosphorus and potassium and various trace elements in the soil, enhance the positive energy of fruit development, promote new roots, enhance tree potential, and lay a good foundation for growth and development in the coming year.
