After the soil is buried, it should be checked frequently before the soil is completely frozen, especially the northwest part of the mound. After the soil is scraped, it should be replenished in time to prevent the grape plants from being hurt by the thin soil layer when they are frozen in cold weather. In addition, we should also pay attention to the grazing of sheep. If you find any soil shortage, you should make it up at any time. Pay attention to the distance between grape seedlings when covering the soil. For those with close row spacing, soil should be taken from different places to cover them, so as not to damage the roots and reduce the cold resistance of grape seedlings.
At the same time, try to bury the soil manually, and don't use a small excavator. The mound buried in this way is very strong. In some plain areas with soft soil, due to the high water content when covering soil, cracks will appear in the mound in cold weather environment. At this time, it is necessary to seal it tightly in time, otherwise the buried plants may be frostbitten. Last winter, we neglected this link and failed to cause air leakage. Some grape plants are frozen to death. Secondly, we should pay more attention to this situation in early spring, and we should not go to the soil too early.
Cover the grass curtain, stick a layer of plastic film, and bury the soil. Basically, nine will do. Grapes under 3 years old should be covered with some corn stalks to keep warm. Or the terrain is not good, such as low sand and thin soil. After covering, it is best to cover the soil with a plastic film and a map around it, as long as it is not blown up by strong winds in winter. This mulch film is similar to a layer of plastic for greenhouse buttons. This can effectively reduce the occurrence of frostbite,
