Clearing snow After snowfall, clear the snow on the fruit branches in time to prevent the branches from bending and breaking due to excessive snow. If the breakage has occurred, the general of the tree guard should be smeared on the fracture of the fruit tree to protect the wound, prevent wound rot and virus infection, and promote the restoration of fruit tree.
After the snow has been removed from the orchard, smoke is used to warm the orchard. Fumigation should be continued for 2 to 3 nights, which can play a good effect in removing cold and preventing frost.
After the tree is covered with white snow, the trunk and main branches should be evenly whitened with whitening agent in time, so that the temperature change of the tree body is stable, which not only prevents frost and sunburn, but also kills the bacteria, eggs and adults in the trunk.
Filling the frozen water in time and filling the frozen trees with frozen water in time before the snow freezes can not only promote the growth and development of the fruit trees, but also keep the ground temperature relatively stable during the cold winter, thereby reducing the frost damage.
