Cuckoo//
Rhododendron is one of the top ten famous flowers, but also the traditional famous flowers in China, mainly flowers with gorgeous flowers, long flowering period, high ornamental effect, and rhododendron flower color is numerous, there are many flower types, its ornamental value is also very high, so it is loved by flower lovers. But after entering the spring, how to maintain the rhododendrons and let them bloom and flourish.
01. Shape the cuckoo
A large wave of cuckoo-shaped beauty figures struck
02. Spring management
1. Rhododendrons can be changed after flowering.
Because rhododendron has mycorrhizae, that is, a fungus parasitic on the rhododendron root forms a symbiotic relationship with the rhododendron root, the rhododendron root provides nutrients for it, and the fungi are conducive to the absorption of water and fertilizer by the root system of the rhododendron, and its role is similar to that of rhizobia, and the new potting soil should be mixed with part of the old potting soil.
2. In the spring, the light is not strong, and the cuckoo can accept direct sunlight.
Spring is the growing season for rhododendrons, pay attention to the application of fertilizer, keep the potting soil moist, and spray around to maintain high air humidity.
Rhododendron because of the high requirements for air humidity, every day need to spray around it several times, more cumbersome, better way is to use waste towels and other absorbent things to water through the water, flat placed around the potted rhododendron, the evaporation of water can form a better suitable for the growth of rhododendron humidity environment, towels dry when watering can be wet.
3. After the temperature rises in late spring, it should be shaded in semi-shade.
4. Early spring pre-flowering fertilizer is very important to promote full buds and vigorous flowering, but it must be mainly phosphate fertilizer, pay attention to thin fertilizer and diligent application. Recommended use of [Daile Manyuan Flower + Daile Boron + 60 days long-acting foliar fertilizer]
【Della Boron】
1. Pure natural organic boron fertilizer, no inorganic salt. The sugar alcohol chelating technique is quickly absorbed by crops and contributes to the balance of plant hormones.
2. The solubility is higher than that of solid boron fertilizers on the market, and it will not agglomerate during use, which greatly increases the utilization rate of boron fertilizers.
3. Promote flower bud differentiation, flower organ development, improve pollination. Reduce the "flowers but not real", "buds without flowers", "flowers without bells", "thick skin hollows", "empty shells", "large and small fruits" caused by boron deficiency, etc.
4. Increase the production of beautiful fruits, and raise the market time in advance
5. Highest grade gold liquid boron fertilizer
【Dai Le Man Garden Flower】
1. It can quickly replenish the nutrients lacking in plants, and the absorption and utilization rate is far greater than that of inorganic nutrients.
2. Obviously promote the differentiation of crop flower buds, and have a very good effect on flower preservation and fruit preservation.
3. Effectively solve the leaflet disease caused by zinc deficiency in plants.
4. Improve the stress resistance of crops, and have a good preventive and alleviating effect on nutrient-deficient diseases such as root rot.
【Foliar fertilizer (imported 60-day long-acting type)】
1. Natural plant extract, regulate plant physiological metabolism, and maintain foliar fertilizer of leaves.
2. A variety of functional biostimulants (74 kinds of synergistic substances), synergistic organic chelating trace elements, increase production and quality of foliar fertilizer.
3. Adopt advanced sustained release technology, long-term effect of 60 days, broad spectrum universal, continuous supply, strong adhesion, rain resistance.
4. The nutrient permeability is strong, providing sufficient photosynthesis for crop growth and development to prevent premature aging.
03. Pest control
Yellowing disease
Symptoms: This disease mostly occurs on the new leaves of young shoots. The flesh between the veins of the leaves fades green and loses its luster, and then gradually turns yellowish-white, but the veins remain green, making the green on the leaves reticulated. Subsequently, the degree of yellowing gradually increases, except for the larger leaf veins, the whole leaf becomes yellow, yellowish white, and in severe cases, it is scorched inward along the leaf and leaf margin.
Prevention and control method: Iron supplementation is the fastest effective and most efficient method, especially in alkaline soil, in the case of poor soil application of iron fertilizer, use [Zhixin Bright Green Iron Fertilizer], spray it every 10 days until the leaves return to normal; in addition, the root irrigation effect for [Zhixin Bright Green Iron Fertilizer] is also very good.
【Zhixin Bright Green】
1. High content:
It is refined by the citric acid chelating process obtained by the United States patent, and the iron content is ≥ 20%;
2. Fast high solubility:
Can be quickly dissolved in water or more concentrated liquids;
3. Quick-acting and easy-to-absorb:
Strong adhesion, fast penetration, easy absorption, very obvious crop fertilizer efficiency;
4. The effect of increasing production is obvious:
When the soil is deficient in iron, it can increase the yield by 10%-20%, and the input is less and the effect is fast.
Net bugs
Symptoms: Adult and nymphs are clustered on the back of the leaf to suck up sap, and a black viscous substance that looks like it has been splashed appears on the back of the affected leaf. This feature is easily distinguished from other stinging insect pests. The back of the whole affected leaf is rusty yellow, and many pale spots are formed on the front, and when the damage is severe, the spots are in pieces, so that the whole leaf loses green, and it looks pale from a distance, and the leaves fall early, no longer forming flower buds.
Control method: Completely remove the fallen leaves and weeds around the potted flowers and bonsai garden in winter. For plants with thicker stems and rougher stems, apply white coating. The most favorable time for pharmaceutical control is at the stage when the overwintering adults are stinging and the first generation of nymphs begin to hatch. Recommend Kyobo Ares [thiamethox isopropylvir + praziperazone]. Spray once every 10-15 days and 2-3 times continuously.
【Thiamethox, isopropylvir + prazidone】
1. It has a good control effect on aphids
2. It has the dual effects of touch killing and gastric toxicity, stopping eating after 4-6 hours after contact; irreversible paralysis knockdown occurs within 6-12 hours; and peak death is reached in 24-36 hours.
3. Long effectiveness, good permeability on the surface of plants, good adhesion.
4. It is more resistant to rain washing, and after use, the agent effectively penetrates into the leaves of the plant to form a secondary insecticidal peak, and the insect eggs are killed at the same time.
Red Spider
Symptoms: Mainly suck the sap of the plant and make the leaves appear gray-white spots. In severe cases, it causes the leaves to turn yellow and fall off. The growth of new shoots is poor and the tree strength is weakened.
Prevention and control methods: by adjusting the microclimate, creating an environment conducive to the habitat and reproduction of predatory predators such as mites to reduce the occurrence of red spiders. Orchards or newly planted orchards that have been endangered by red spiders are recommended to use [Full Silence].
【Full silence】
1. The product is highly effective and micro-toxic, targeting a variety of farmland mites including red spiders, white spiders and yellow spiders, including eggs, young mites, nymphs, and adult mites.
2. Relatively safe for its natural enemies and bees, such as: Chinese grasshoppers, mite-eating ladybugs, predatory mites, etc.
3. The ingredient content is 30% nitrile pyrimethoxate suspension agent, which is a brand new patented compound and has no interaction resistance with the acaricides on the market.
4. Quick-acting + long-term effectiveness, 2-4 hours after the drug, mite poisoning and death, the duration of action up to 25-30 days.
