Dikangbao orange management technical process
Navel orange (citrus, grapefruit) organic planting anniversary management technology system, this system has experienced more than ten years of practice and effort, in line with the national navel orange (and citrus, grapefruit) planting technology planting technology control, completely create a system planting demand! This system reduces the use of chemical fertilizers and chemical pesticides, hormones and chemical herbicides, and plays an irreplaceable effect on the prevention and control of huanglongbing disease! The specific production technology is as follows:
January (small cold - big cold) flower bud morphological differentiation period; winter shoot germination period; tree nutrient accumulation period to promote flower bud differentiation, control the winter shoots using white paint map trunk, cold protection, disease and pest prevention overwintering egg laying. For the tianniu, the gidding insect control is properly controlled by water, and the winter shoots are promoted to control the flowers; the diseases and insect pests are in a dormant wintering state during the month.
February (Lichun - rain) spring shoot germination period to promote flowers and flowers 1, spray stone sulfur compound plus calcium double plus like to do pre-bud prevention and control; 2, after rain to apply germination flower-promoting fertilizer, mainly biological red, a bottle of 160 ml per acre, with a pound of sugar residue fertilizer; some diseases and insect pests in this month are in a dormant state, a small number of overwintering red spiders begin to lay eggs; scabs, anthrax began to infect. Use geocomb microbial fungicides or protective and biological insecticides for prevention and control. Do a good job of pruning before flowers.
March (sting - spring equinox) spring shoot growth period, bud stage, first flower - full flowering period, bee pollination, disease prevention and insect 1, flower bud stage spray amino acid 70 ml, add borax 2 two, add water 150-200 pounds (1-2 times); 2. grow strong trees, spring shoots are too strong to carry out biological setback spraying, each pack of 80 grams of water 700 pounds plus mineral potassium dihydrogen phosphate 0.4%; the peak period of egg laying of a generation of red spiders in this month; the period of scabies, acute anthrax infection. Ibid.
April (Qingming - Gu Yu) blooming - Xie flowering period, young fruit development period, the first physiological fruit fall period to promote fruit and prevent diseases and insects 1, apply xie flower fertilizer, xie flower two-thirds of the time to apply, each plant 5 two wojin sugar residue fertilizer; 2, after the flower, spray 2-3 times amino acid 70 ml plus high purity potassium dihydrogen phosphate 2 two plus water 100 pounds; 3, after the first physiological fruit fall after the first physiological fruit spray bioflus plus mineral potassium dihydrogen phosphate fertilizer once; (the amount of water consumption is the same as the first time) in this month, such as a generation of red spiders did not get good control, then the red spider occurred seriously Acute deciduous anthrax begins to occur, the optimal period for scab infestation. Prevention and control is the same as above, at the same time, hanging bottles this month to trap insects, the method is to use a small amount of fruit chopped plus a little avermectin plus a little honey in the mineral water bottle with a triangle gap, covered with a tile to cover the rain, replaced once every half a month. Place one or two per tree.
May (Lixia - Xiaoman) the second physiological fruit fall period, young fruit development period, summer shoot germination period fruit preservation 1, the second physiological fruit fall before the spray bio-frustrating mineral potassium dihydrogen phosphate fertilizer once, control the summer shoots, began to remove sporadic summer buds; 4, do a good job of tree tray grass cover; 5, timely elimination of water; the beginning of the shell worm in this month, the red spider area selectively occurs, anthrax, ulcer disease completed the initial infection, reproduction in the tree, in the beginning of this month can use cuprammy mixture (prepare lime block ash 20 kg, Copper sulfate 10 kg of selected river copper, ammonium carbon 30 kg content of more than 17 percent, cold water 30 kg, hot water 60 kg, a large container four square barrel, first of all the copper sulfate in hot water dissolved, and then with cold water to stir the lime into an emulsion, put into a large container, add ammonium carbon, and finally slowly add copper sulfate along the clock direction to stir, and finally become milky after dripping into diesel sealed, and then covered with film sealed for seven days after taking out and using, each time take a pound of water 30 kg spray can be, Each drip of diesel can be used for a long time) spray 2-3 times, each time at half a month interval. This square melon fruit and vegetable peanut Huaishan can be used. Root irrigation once xanthinin formula.
At the end of the second physiological fruit fall in June (mango seed - summer solstice), the summer shoots are picked in the summer shoots, and the fruits are preserved 1, and the summer buds are continued to be smeared once every 3-4 days; 2, the trenching in the end of this month uses 10 kg of Kangbao microbial organic fertilizer (20 kg of large trees) Wojin sugar residue fertilizer one pound to one kilogram per plant; 3, dredge the drainage ditch, drain the accumulated water in time; the month focuses on the prevention and control of sand skin disease, rust mites, and other diseases and insect pests similar to may.
In July (small summer - big summer) fruit expansion period, summer bud picking summer buds in preparation for the release of autumn shoots 1, continue to pick summer buds to put autumn shoots; 2, apply autumn shoots to apply heavy fertilizer, accounting for 40% of the annual fertilization, 15-20 days before the release of autumn shoots (this fertilization can be put to the end of June to fertilize the amount) 3, sprinkle sugar residue fertilizer one pound to one kilogram per plant, and carry out a summer shear; 4, summer drought prevention, moisturizing. Chronic anthrax began to occur, autumn red spiders gradually emerged, rust mites, aphids, black spinosa whiteflies, leafminer moths occur, focusing on prevention and control. Apply xanthexin formula once.
In August (liqiu - in the summer) fruit expansion period, autumn shoots put autumn shoots 1, put autumn shoots, and then smear 1-2 buds before putting the shoots, which is conducive to the neat germination of autumn buds; 2, drought prevention and moisturizing; 3, put later to evacuate, leave 2-3 autumn shoots per base; 4. Sprinkle sugar residue with one pound of fertilizer per plant.
September (white dew - autumn equinox) autumn shoots turn green old ripening period, the fruit rapidly expanded in the stage of strong fruit 1, strong fruit fertilizer, in the autumn shoots from the pruning to green stage of the application of sugar residue fertilizer one kilogram per plant with biological red bottle per acre of water irrigation; 2, drought prevention and humidification, irrigation loose soil, cover; 3, do a good job of fruit preparations. High purity potassium dihydrogen phosphate was sprayed. Red spiders, rust spider secondary peaks, anthrax, ulcer disease repeated infection using non-copper preparations to prevent and control.
October (cold dew - frost) fruit rapid expansion stage of strong fruit 1, late release of autumn shoots in the orchard, autumn shoots turn green old ripening period of strong fruit fertilizer and spray foliar fertilizer (high purity potassium dihydrogen phosphate); 2, cold protection and humidity, loosening the soil; 3, do a good job of fruit support. 4. Spray biological setback twice, each package mixed with 500 pounds of water plus carbon leaf fertilizer 600 times, once every 25 days.
In November (Li Dong - Xiao Xue) the fruit is ripe, the flower buds are differentiated, and the winter shoots are ready for harvest. Harvesting begins in the second half of the month, prevent winter shoots 1, do a good job of preparation before harvesting, do not irrigate water for 10 days before harvesting; 2, apply base fertilizer about 10 days before and after harvesting, ditch each plant buried Incomb microbial organic fertilizer 20 kg of sugar residue fertilizer one kilogram; 3, appropriate water production, anti-winter buds to promote flower bud differentiation.
December (heavy snow-winter solstice) flower bud differentiation period promotion flower bud differentiation, prevention winter treetops
1, harvest trees in stages; 2, fertilization after harvesting, each plant sugar residue fertilizer one pound plus amino acid one or two with water application; 3, young fruit trees strong and vigorous tree control water, control winter shoots to promote flower bud differentiation; 4, combined with broken roots for deep soil transformation; 5, after fruit picking, the use of stone sulfur compound plus calcium double plus joy twice in a row, half a month apart. Remarks: 1, the citrus cultivation calendar, suitable for most areas of citrus, orange, grapefruit! 2, combined with the pruning technology, to reshape the principle of light pruning! 3. Do a good job in the garden clearing work of the orchard before the flowers The prevention and control of canker disease sand skin disease in May, the prevention and control of sand skin disease rust mite in July and the red spider removal work in October!
