Freezing damage: During the wintering period of fruit trees, the resistance of various tissues and organs to cold temperatures is different. Sometimes the branches and buds are partially frozen, resulting in a decrease in production in the current year. In severe cases, pruning will die, posing a serious threat to production. There are many causes of frost damage. Comprehensive measures should be taken in production to strengthen tree protection and prevent freezing damage. Grapes, apples, pears, walnuts, peaches, and other saplings can be used to protect the soil from cold, coat the main stem of the grass, and cultivate the crescent-shaped soil on the windward side. The effect is very good. The frozen fruit trees should be lightly cut and later cut to ensure the early water supply, timely fertilizer application and nutrient supply.
Frost damage: The degree of frost damage and the location of the hazard vary with frost duration, temperature drop, and the phenology period of the fruit trees. Apricots, pears, and apples have the phenomenon of early spring freezing, and young fruits and young leaves in individual years are also affected by frost. Spraying on the fruit trees with a solution of potassium naphthaleneacetate (0.025%-0.5%) before germination and at the end of autumn, or pouring back the slurry in the early spring, or whitening the trunk and delaying the germination period, can prevent frost.
Wind damage: The wind can deviate the tree body or eccentricity. In winter or early spring, strong winds can easily cause the young fruit trees to drain and die. The spring dry wind often blows the tender shoots to shorten the flowering period and reduce the fruit setting rate. If there is wind during the flowering period, artificial pollination can be conducted; during the production season, there is wind, and it is necessary to set up pillars for the fruit trees to prevent lodging; if there is wind before harvesting, the tree trays or tree trays can be deeply mulched to reduce the damage of fruit drop.
Strokes: Strokes are heavier in young fruit trees, often causing tree disorders and affecting early results. The prevention method is to increase the amount of water in the early stage of fruit tree growth, increase the application of phosphorus and potassium fertilizer, timely picking the heart, prompting the branches to enrich, and enhance the wintering of fruit trees.
