1. Early application of basal fertilizer: It is one of the key measures to prevent frost and increase efficiency. It can nourish strong trees and enhance the cold resistance of fruit trees. The winter fertilizer should be mainly decomposed or semi-decomposed farmyard manure, combined with nitrogen, phosphorus, potassium and other quick-acting chemical fertilizers. It can be applied by opening a circular trench or digging a trench.

2. Irrigation before freezing: The heat capacity of water is higher than that of soil. Winter soil moistens water, which can maintain and increase temperature with water and prevent the occurrence of freezing damage. Since orchards are mostly built on hillsides, hills, and floodplains with shallow soils and poor water retention, fruit trees are most likely to suffer drought and freezing damage. Therefore, fruit trees need to be irrigated 1 to 2 times before winter.

3. Surface covering: Covering the rows of fruit trees with straw, wheat straw, hay, corn stalks, etc. can block cold wind from invading the roots, reduce frost damage, reduce soil water evaporation, and protect moisture and increase temperature. effect.

Extended information:

Fruit tree pruning includes winter pruning and summer pruning. Pruning mainly involves cutting off leggy branches, drooping branches, back branches, overly dense branches, diseased branches and weak branches. Pruning can control the amount of fruit and improve the quality of fruit trees.

Pruning is to reshape the fruit tree. The pear tree has three main branches scattered and layered, the peach has three main branches in a happy shape, and the pomegranate has a natural round head shape. Summer pruning is from June to August, as long as you If it feels dense, you can cut off some of the twigs from the branches so that they can be shaped to allow light to pass through, but don't cut off the fruiting branches, otherwise you won't be able to eat the fruit.

Winter pruning is mainly short pruning, which means cutting off part of the branches from the top, 1/3 or 1/2. The purpose is to promote the growth of fruit trees and reduce fruiting. You can also cut off part of the fruiting branches. , because there is a causal relationship between the results of fruit trees. The more fruit they bear, the smaller the fruit will be.
