Answer: Adjust the buried soil thickness and cold protection. For some varieties that are not resistant to low temperature, the second cold-proof soil should be buried before freezing. The thickness of the buried soil is generally 15 cm. In order to achieve a better cold protection effect, when the second cold protection soil is buried, the corn straw or weeds can be covered and then buried. In this way, the temperature of the soil at the base of the grape roots can be significantly increased, which is conducive to the safe wintering of grapes.
