Whether jujube trees can survive the winter safely is an important factor to ensure the survival and harvest of jujube trees. Generally, plants with early survival and high degree of lignification of the branches have developed root systems, which is conducive to safe overwintering, especially the newly planted jujube seedlings. Safe overwintering of jujube trees. The following aspects need to be done to prevent freezing damage of jujube trees during winter: Whitening the trunk When the temperature drops to zero, scrape off the old bark and warped bark of the trunk, and whiten it in time. When scraping the bark, burn the scraped old bark and warped bark together and don't leave it in the garden. The whitening agent can be made by mixing quicklime, table salt, pesticide residue, soybean binder and water in a ratio of 1:0.2:0.2:4:3. This can effectively inhibit the occurrence of frostbite, and can also play a role in preventing and controlling pests. Root neck cultivation of young trees should be root neck cultivation, the height of the cultivation should not be less than 40-50 cm, to prevent the aggravation of frost damage and the damage caused by the alternation of freeze-thaw after the root neck thawed in early spring. Cold-proof bandages should be carried out on young jujube seedlings (below 6 years old) before entering winter. The material of the cold-proof dressing is cotton felt, and the height of the dressing should be more than 100 cm from the ground. Cold-proof dressing of young jujube trees can not only prevent the hazards of voles and *** in winter, but also prevent the occurrence of freezing damage in winter. Timely delay the winter pruning time. The winter pruning time of jujube trees should end before budding, especially to avoid pruning during the severe winter. Clean up the snow in time. After it snows in winter, you should clean the snow around the tree tray in time to reduce the reflection of sunlight and increase the ground temperature. At the same time, the snow on the branches should be removed to prevent the snow from melting and freezing the bark. Anti-freezing storage of jujube grafted seedlings. Jujube grafted seedlings should be dug out before freezing on the soil. After pruning, grading, and bundling, they can be dug in the open field or placed in a cold storage for storage. Cover the film to increase the temperature. Remove the soil in time after the soil is frozen in spring, and cover with mulch to increase the temperature and protect the moisture.
