2. Method of burying soil

Northern grapes need to be buried in soil to prevent frostbite. Pour freezing water once 10 days before burying the soil to avoid freezing. Bury the soil when the temperature continues to be two degrees Celsius. The first time, you don’t need to bury it too thickly, as long as it can cover the branches and vines. When the temperature drops to zero, bury the soil for the second time. This time it should be thicker, and the roots should be covered with hay to increase the temperature, so that it can survive the winter more safely.

1. Anti-freeze methods

1. Water the frost sealing water at the right time: The temperature in the north is relatively low, so it is necessary to bury it in the soil to avoid frostbite. It is necessary to pour freezing water once 10 days before burying the soil. The purpose is to prevent its root system from being frozen and to prevent drought in early spring. Pay attention to watering thoroughly when watering, watering enough to saturate the soil. After watering, wait until the soil is slightly dry before burying it.

2. Bury cold-proof soil in time: after the temperature drops in autumn, it should be done in time Carry out pruning and tie up the branches and vines. Because the temperature is low and the wind is strong in early winter, the water in the branches and vines is easy to evaporate, which is detrimental to the later winter and the growth of the second year. In addition, if the temperature continues to be stable at two degrees, it should be buried with cold-proof soil. The soil does not have to be too thick for the first time, as long as the branches and vines are not exposed.

3. Bury the second cold-proof soil: the second time Cold-proof soil should be carried out when the temperature remains below freezing. At this time, the buried soil should be thickened, and the specific thickness will be determined according to the temperature. If the low temperature 80 centimeters below the surface is minus 2 degrees, then the thickness of the cold-proof soil should be between 20 and 30 centimeters. Every time the soil temperature drops by one degree, the thickness of the buried soil should be increased by 10 centimeters. By analogy, this way you won’t get frostbite. Pay attention to the width of cold-proof soil, which should not be less than 1.2 meters. In addition, the roots should be covered with corn stalks or hay to increase the temperature of the roots and avoid frostbite.

2. Method of burying soil

The commonly used methods of burying soil are the above-ground soil burying method and the underground soil burying method. Among them, the method of burying the soil on the ground is to press the pruned branches and vines on the ground, and then cover them with soil and seal them tightly. The underground soil burial method is to dig a deep trench where the branches spread, with a depth and width of about 30-50 cm, and then press the branches into the trench and cover it with soil.
