The trunk is painted white in winter. Lime pulp is added with water to adjust the lime slurry. A small amount of salt is mixed and evenly painted on the cherry trunk to reflect more sunlight to prevent the damage caused by large temperature difference between day and night. Before the root-retaining soil is frozen, the crescent-shaped soil with a height of 50 cm at a position 30 cm northwest of the young cherry tree can effectively prevent the root neck from freezing and pulling.
Watering frozen water to irrigate frozen water has a definite effect on freezing and freezing. When people are able to enter the ground after irrigation, lightly soil the soil to cut off the soil capillary.
The mulch-covered young cherry tree roots are generally distributed in the soil layer of 20-30 cm from the ground, covering the mulch, and have a certain warming effect on the shallow soil.
After the oil coating is frozen in winter, the animal oil of lard is applied to the newly planted sapling main body, and then a plastic film is wrapped around the trunk to a thickness of 0.03 mm, which is released before April of the following year, and water evaporation of the tree is suppressed. , It can effectively prevent young cherry trees from drawing.
