1, management of flower bud differentiation period: remove the growing new shoot tip together with several tender leaves to promote inflorescence development, increase fruit setting and reduce flower and fruit drop. Every 10 day, spray the tip, redundant buds and lateral heart parts with "Cuihuawang No.3" for three times in time to inhibit the excessive growth of the main shoot, balance the flower amount and improve pollen.
2. Pruning wound protection: major modification of fruit trees, high grafting and head changing, scraping and curing rot, and plastic pruning will inevitably cause wounds. If it is not closed in time, it will be dry and polluted, which will lead to a large number of airborne germs and viruses invading the tree from the wound and inducing fruit tree rot and other diseases. Callus antiseptic film is called "chemical bark", which is an oily soft solid with high technology content. When directly applied to scissors, it can quickly form a tough soft film close to wood, protect the growth of wound healing tissue, prevent the infection of rotten bacteria, soil and rain, prevent freezing and prevent the wound from cracking.
3. Scientific bagging: Grape bagging can obviously improve the fruit quality, and the bagging period generally begins immediately after the fruit is stable, the whole ear is trimmed and the grain is thinned. Traditional manual bagging is time-consuming, laborious, costly and troublesome. High-tech non-film bag is a new type of high-fat film powder with high concentration. Rapid formation of polymer ultra-thin soft film by spraying fruit surface. Spraying the surface of grape fruit with 0/000 times of water from the mother liquor without film bags at the young fruit stage for the second time and the third time every 25-30 days can replace plastic film bagging, protect fruits and leaves, prevent pathogen infection and optimize fruit development level.
4. Prevention and control of diseases, pests and root rot: There are many diseases and pests of grapes, and the most headache for fruit farmers is mold, which may infect grapes from germination and mainly harm branches and leaves and fruits. Using corresponding chemicals+new high-fat film for prevention and control can greatly improve the utilization rate of effective components of pesticides, reduce the use of pesticides and reduce pesticide residues. Grape root rot nematode disease leads to vascular bundle necrosis or root bark rot, which is serious and difficult to control. Irrigation with 10% mirex soil contact agent or 10% keliandan granules combined with Genshitong capsule can promote the effective components of pesticides to kill fruit tree pests.
5. There is a new method to protect flowers and strengthen fruits: from flowering stage to expansion stage, the pipeline is not smooth, which will affect the nutrition of the tree, and condensed substances will be produced in the pipeline, which will lead to the phenomenon of falling flowers and fruits, which can also be called physiological falling flowers and fruits. Fruit development needs a strong mother body and a healthy nutrient circulation and transportation system, and needs sufficient water and fertilizer matching supply and good digestion function. Spraying Zhuangguodiling before flowering, young fruit stage and fruit expansion stage can thicken the fruit pedicel, improve nutrient transport, effectively reduce the rate of flower dropping, fruit dropping and fruit cracking, and make the fruit colorful and delicious.
6, disinfection and sterilization to prevent bacterial invasion: Grape trees, like other fruit trees, will have a variety of cortical diseases. If not treated in time, it will affect the growth of trees and the development of fruits. Spray orchards, trunks and branches with 1000 times Guan Shu solution in time to prevent and control airborne diseases and disinfect plants.
The author analyzes that ecological agricultural materials are environmentally friendly and pollution-free, and all aspects of management should be matched, and physical regulation and protection should be implemented for plant growth, making great contributions to modern plant protection and stepping onto a new level.
