When grapevines in the north spend the winter, they need to be buried in soil to keep warm. They should be watered with frozen water 10 days before burying to prevent the roots from being exposed to the winter. When the temperature is at a continuous low temperature of 2 degrees, bury the soil for the first time. Be careful not to make it too deep, so as not to expose the branches and vines. When the temperature drops to 0 degrees, the soil should be buried a second time. At this time, the thickness should be increased and kept above 60 centimeters. Also cover it with hay or corn stalks to increase the temperature and avoid frostbite.

1. Water the frozen water: Bury the soil in winter. Water the frozen water once about 10 days before burying the soil. This can prevent the root system from being damaged by freezing, and also Drought in early spring can be avoided. Pay attention to watering enough when watering, water thoroughly, saturate the soil, and cover with soil when the soil dries slightly.

2. Timely removal and burial: in northern areas in early winter When the temperature is low and the wind is strong, pruning must be carried out in time to avoid excessive evaporation of water in the stems and branches. After pruning, the branches and vines should be tied up and buried in soil when the temperature is at 2 degrees continuously. Don't bury too much soil for the first time, just don't expose the branches and vines.

3. Bury the soil for the second time at the right time: when the temperature is When the temperature is 0 degrees, a second antifreeze soil should be buried. At this time, the thickness of the buried soil should be increased to avoid frost damage. Also prepare an appropriate amount of hay or corn stalks to keep warm and place them on the root system to increase the temperature. Be careful not to dig too close to the roots when digging. At this time, the width of the buried soil is about 1.8-2 meters, and the thickness is more than 60 centimeters.

2. Buried soil at several degrees below zero

< p>Although grapevines have a certain degree of cold resistance, the temperature in the northern region is too low and they are prone to frostbite if they are not buried in soil. The specific temperature below zero for burying soil depends on its cold resistance. Usually when the temperature is minus 6 degrees, the root system will be frostbitten, and when the temperature is minus 8 degrees, the plant will easily freeze to death. Therefore, the temperature should be controlled above minus 6 degrees. It is recommended to bury the soil when the temperature drops by 2 degrees to avoid freezing.
