The temperature in the north is low in winter, so you need to bury it in the soil during the winter to avoid frostbite. 10 days before burying the soil, pour frozen water once, water it thoroughly, and then cover it with soil when the soil dries slightly. When the temperature continues to drop by two degrees, bury the soil once to cover the branches and vines. When the temperature continues to be 0 degrees, bury the soil for the second time. At this time, it should be slightly thicker and covered with hay to keep it warm, so as to avoid frostbite.

1. Pour and freeze water

1. Pour frozen water

The temperature in the north is relatively low in winter, so you need to bury the soil to survive the winter. 10 days before burying the soil, pour freezing water once. This will not only prevent root frostbite, but also avoid drought in early spring. At this time, watering should be done thoroughly and enough to saturate the soil. Wait until the soil dries out slightly before covering with soil.

2. The first burial

< p>The burial of soil should be carried out in two steps. The first time is when the temperature lasts two degrees, the pruned branches and vines should be tied up and covered with a layer of soil. Note that the soil does not need to be too thick, as long as the branches and vines are not exposed. They need to be pruned after the temperature drops in late autumn to prevent the branches and vines from being evaporated, which will be detrimental to next year's germination and growth.

3. The second burial

< p> When the temperature is continuously at zero degrees, the soil should be buried for the second time. At this time, the thickness of the buried soil should be increased, and an appropriate amount of hay or corn stalks should be prepared to cover the root system to increase the temperature and avoid root damage. freeze. Be careful to dig as far away from the roots as possible. The width of the buried soil should be maintained between 1.8-2 meters, and the thickness should be more than 60 centimeters.

4. Specific methods of burying soil

< p>Two methods are often used when burying soil. One is the method of burying soil on the ground. Directly lower the pruned plants to the ground, and then cover them with soil to seal them tightly. The specific thickness of the soil depends on the temperature. The lower the temperature, the thicker the soil will be. The second is the underground burial method. Dig a ditch along the branches to a depth of 30-50 centimeters, then press the branches and vines into the trench and cover them with soil. This method is more suitable for plants with many branches and vines.
