1、 Master cold resistance

If you want it to survive the winter better, you should know its freezing ability. It has certain cold resistance, but when the low temperature drops to minus 6 degrees, it is vulnerable to freezing injury, and when it falls to minus 8 degrees, it will be frozen to death. Therefore, the temperature should be kept above minus 6 degrees

2、 Pouring and freezing water

Before burying the soil in winter, it is necessary to water the frozen water once, about 10 days before burying the soil, so as to prevent its root system from freezing damage and avoid the drought in early spring. Pay attention to watering thoroughly and sufficiently when watering, so as to saturate the soil. Then bury the soil when the soil is slightly dry

3、 Bury the first cold proof soil

Prune the grapes after they have fallen leaves, dispose of all the dead branches and rotten leaves, and bind the branches and vines. When the temperature continues to be about 2 degrees, bury the soil. Pay attention not to bury too much soil for the first time, just don't expose the branches and vines

4、 Bury the second cold proof soil

For the second cold proof soil, it is recommended to prepare an appropriate amount of corn straw or hay when the temperature lasts 0 degrees, so as to better protect the root system from freezing damage. At this time, the width of the cold proof soil buried is about 1.8-2 meters, and the thickness of the soil covering the branches and vines is more than 60 cm, so as to ensure that it will not be damaged by freezing
