2. Root stem earth. The rhizomes of fruit trees are the most sensitive to freezing damage. Before the winter, the roots and stems of fruit trees are sealed with mounds, which can effectively prevent the roots and stems of fruit trees from freezing.
3. Plastic film cover. After clearing the orchard, covering the ground with a layer of plastic film or crop stalk can prevent the roots of the fruit tree from being frozen, as well as the effect of protecting the sap, and it plays an important role in preventing the freezing of the fruit trees during drought years.
4. Irrigation, pruning. In drought years, water should be poured before the fruit trees are overwinter to prevent the roots of the fruit trees from freezing. Combine the winter shears before winter to cut the young shoots that are vulnerable to freezing, which can enhance the cold resistance of the fruit trees and reduce the frost damage of the fruit trees.
5 trunk white. Before winter, the trunk of fruit trees is coated with a small amount of salt in lime mortar to reduce the temperature difference between day and night of trunk and reduce the frost damage of fruit trees. For young trees that are not tolerant to cold, the main trunk should be bandaged with straw to enhance its ability to prevent cold.
6. Shake off snow. After the heavy snowfall, the snow will be shaken off in time to prevent the fruit trees from freezing.
Fruit trees wintering method
1. Fertilize shallow plough. Every 1000m2 is used for spreading 1000kg of fire-soil ash or 300kg of stalk ash. Shallow ploughing is about 5cm. Turn the fertilizer into the soil to provide nutrients for the fruit trees, enhance the resistance of the fruit trees to overwintering, and loosen the soil to facilitate the absorption and insulation of the soil and reduce the fruit trees. Freezing damage.
