1. When to bury the soil

The temperature in winter in northern China is too low, usually below minus 6 degrees. If such an environment is not covered with soil, the grape branches will be frostbitten, which will affect the germination and flowering of the next year, and may even cause the death of the plants.The time of burying soil should be strictly controlled, usually half a month before freezing, probably in mid-November.If buried too early, branches will germinate in a warm environment, if buried too late frostbite.

2. how to winter

1. If you want it to survive the winter safely, you should pay attention to the method.Before burying soil, it is necessary to irrigate freezing water once in advance, so as to prevent and control freezing damage to roots and avoid drought in early spring.When irrigating, we should irrigate enough to saturate the soil, and then bury the soil when the ground is slightly semi-dry.

2. In addition to watering, prune.Usually in the middle of October every year, after defoliation, autumn pruning should be carried out to completely remove the dead branches and rotten leaves from the orchard, remove the grapes from the shelves, and put the branches and tendrils smoothly on the ground and tie them with straw ropes.Pay attention to the first buried soil can not be too much, not exposed branches on the line.

3. The soil should be buried twice, and the second time should also be carried out before freezing.If young trees are to be buried early, big trees can be appropriately postponed.When burying soil for the second time, it is also necessary to cover a proper amount of hay or corn straw, which can increase the temperature of the roots and is beneficial to cold prevention.At this time, the thickness of the soil buried on the branches and tendrils should not be less than 60 centimeters, and the width should be between 1.8 and 2 meters.
