1、 When will the earth be buried

The temperature in winter in northern China is too low, usually lower than minus 6 degrees. If this environment is not buried, it will frostbite the grape branches, affect the germination and flowering of the next year, and even cause plant death. The time of soil burial should be strictly controlled. It is generally carried out half a month before freezing, about the middle of November. If the soil is buried too early, the branches will sprout in a warm environment. If the soil is buried too early, they will be frostbitten

2、 How to spend the winter

1. If you want it to survive the winter safely, you should pay attention to the methods. The root system can be prevented from being frozen in advance by watering in spring. When filling water, fill enough to saturate the soil, and then bury the soil when the ground is slightly semi dry

2. In addition to watering, pruning should also be carried out. It usually starts in the middle of October every year. After falling leaves, it is necessary to carry out autumn cutting, completely remove the dead branches and rotten leaves from the orchard, take off the grapes on the shelf, put the branches and vines smoothly on the ground and bind them with straw ropes. Pay attention not to bury too much soil for the first time. Just don't expose branches and vines

3. The earth shall be buried twice, and the second time shall be carried out before freezing. If the young trees need to be buried early, the big trees can be pushed back appropriately. When burying the soil for the second time, cover an appropriate amount of hay or corn straw, which can improve the temperature of the root and is beneficial to cold prevention. At this time, the thickness of the buried soil on the branches and vines shall not be less than 60cm, and the width shall be between 1.8-2m
