1. Replenishment and Fertilization: Frost often causes damage to the buds, young leaves, flower organs, and shoots of fruit trees in different degrees. To restore the tree vigor as soon as possible, fertilizer and water management should be strengthened to supplement the nutrients of the tree and improve the cell fluid of the fruit. Concentration, enhance tree vigor's drought resistance and disease resistance. After flowering, top-up organic fertilizers, inorganic bio-fertilizers, or special fertilizers for fruit trees, etc., together with the new high-fat membrane 500 times liquid + phenanthrene 800 times, pay attention to spray twice to restore the tree vigor, improve the tree resistance Sex.
2. Application of pesticides and insecticides: After the trees are frozen, the disease resistance is reduced, and the pests and diseases are easily invaded. According to the "Taobao Guide for Agricultural Materials," it is necessary to spray 1000 times of the general tree of nursery trees (500 kg). )Spray tree trunks and branches to keep warm, disinfect and prevent frost, hinder the wintering virus from landing on the tree, reproduce the fruit tree life command system to wake up early, keep flowers, preserve fruits, and mix with various pesticides.
3. Wind and flower protection: Fruit trees often suffer from low temperature, strong winds, and late frost during the flowering period, affecting normal pollination and fruit setting. Before flowering, care should be taken to keep flower buds in proper condition and wait until the fruit is set before proceeding with fruit thinning. The victims of fruit trees should not be trimmed in the short term. They should adopt methods of late fruit thinning or fruit keeping. They should retain fruits that have not been victimized or suffer light damage, ensure multiple results and produce good results, and recover losses caused by frost.
