Buried in the cold
When the minimum temperature falls to 0°C during the night, the buried soil shall be buried, and the buried thickness shall be 40 cm above the upper part of the shoots. The top width of the cover soil shall reach 60 cm and the bottom width shall be 140 cm or more to protect the root system from frost damage. When the minimum temperature at night falls to -3°C (usually before November 5th), the earthwork must be completed. The early cold currents in individual years can cause frostbite, and they need to be unloaded or covered under the cold current. Take care that the soil should be taken away from the roots as much as 80 cm away from the root.
