How to keep fruit trees warm in winter

1, shallow tillage with fertilization. Spraying 1000 kg of fire mud ash or 300 kg of plant ash every 667 square meters, shallow tillage about 5 cm, turning the fertilizer into the soil can provide nutrients for the fruit trees, enhance the overwintering ability of the fruit trees, make the soil fluffy, help the soil absorb heat and reduce the freezing damage of the fruit trees.

2. Rhizome cultivation. Rootstocks of fruit trees are most sensitive to freezing injury. Sealing fruit tree rootstocks with mounds before winter can effectively prevent fruit tree rootstocks from freezing.

3. Plastic film mulching. After clearing the orchard, covering the surface with a layer of plastic film or crop straw can prevent the root system of fruit trees from freezing, and also has the function of moisture conservation, which plays an important role in preventing fruit trees from freezing in dry years.

4. Irrigation and pruning. In dry years, the fruit trees should be watered before overwintering, so as to avoid the root system of the fruit trees from freezing. Winter pruning before winter can enhance the cold resistance of fruit trees and reduce the frost damage of fruit trees.

5, the backbone is painted white. Before winter, adding a small amount of salt to the trunk of fruit trees with lime slurry can reduce the temperature difference between day and night and reduce the freezing injury of fruit trees. For young trees that are not cold-resistant, the trunk should be wrapped with straw to strengthen the cold resistance.

6. Shake off the snow. After the heavy snow, shake off the snow on the crown in time to avoid freezing the fruit trees.
