Main tasks: applying topdressing, anti-Japanese burning, high picking, pruning, pest control, planting grass, etc.
First, top-dressing: The application of large-scale fertilizer without expanding big fertilizers promotes the fruit to increase twice. The plant applies 2-3 lbs of organic bio-compound fertilizer, which enhances the firmness of the fruit. The leaf, fruit and branches are sprayed with lactic acid. 600 times calcium. The stems were coated with fruit amino acid stock solution for 2-3 consecutive times, once every 10 days.
Second, anti-Japanese burning: water spray in the park, ground cover, fruit week with newspapers, shady hay shading daily burning. The bagged fruit enlarges the vents in the two corners to reduce the temperature inside the bag and avoid high-temperature burning in the bag.
Third, grafting: high dead head, should be connected, the use of new branches hardened, branches, splicing, with wooden buds, then do not cut the original species branches, not hair, to avoid the buds in the case of cold winter freeze-dried new Send buds.
Fourth, pruning: cut and produce branches and dense branches, pests and branches, mainly sparse, not short, short cut after the new branches are not aging, easily lyophilized. In particular, the Qin Mei breed is prone to new branches and cannot be forced to cut short. The absurd branch is free from space and has space reserved. Objectives: Ventilation and light transmission are beneficial to the growth of fruits and reduce the occurrence of gray worm mold and gray mold.
V. Pest Control: Diseases include gray mold, brown spot disease, insect pests such as pears, and mulberry shields.
Comprehensive prevention and control: the use of pruning, ventilation and light transmission, unfavorable to the living environment of the above pests and diseases, reducing the number of generations of breeding, fertilizing and strengthening the trees, enhancing tree resistance and immunity, and the occurrence of diseases and insect pests is reduced.
Chemical control: spray 25% of Guinness EC 6000-7000 times plus 40% good labor EC 1200-1500 times plus soft water 4000 times. Another option can also be used: spray 70% nano-Whsen WP 1000 times plus 70% of precious water dispersible granules 10000-15000 times plus soft water 4000 times. Red spiders have orchard plus 1.8% avermectin microemulsion
3000-4000 times liquid and foliar fertilizer calcium lactate.
Six, yellowing disease: due to iron deficiency, root rot, excessive load, a single chemical fertilizer application of soil hardening, long-term root rot caused by moist, should be comprehensive prevention and treatment of yellowing disease. It is recommended to use the following formulas: roots each plant big three-billion fertilizer + 2-3 kg + Sterakup Irrigation using 20,000 times liquid + 25% Guinness EC + fruit friends 400 times the supply of amino acids nutrients, fill iron deficiency governance root rot.
Branch fruit coating fruit friends amino acid stocks repeated absorption, amino acid conversion of kiwifruit required protein, nutritional enough, tree robust, less overload yellow.
Foliar spray (chelating iron fertilizer) top green concentration 5000-6000 times liquid.
Seven, planting grass: planting grass between rows, varieties of red and white clover or grasshoppers, used to improve the soil to improve soil organic matter content. Mu amount of red and white clover 0.5-1 Jin, sowing shallow cover, after the emergence of light put fertilizer and weeds, the next flower buds cut, turn under the tree disk.
