The overwintering vegetables in the open field mainly include garlic, onion, spinach, lettuce, peas and other cold-resistant vegetables. Pay attention to the following points in production: 1. Pour antifreeze water to increase cold resistance. According to the soil moisture, combined with plant growth conditions, water overwintering water at appropriate time to improve crop resistance to cold. 2. Temporarily set up wind barriers to reduce cold wind attacks. At the windward position of the vegetable fields with conditions, corn stalks or other crop stalks can be used to temporarily set up wind barriers to reduce the impact of cold wind on vegetables. 3. Check the mulch to prevent it from being damaged by wind. If the mulch is laid in the open field, if the coverage is not tight, it will be easily blown by strong winds in winter and will not have the effect of increasing temperature and moisture. Therefore, before the arrival of severe winter, check the mulch coverage of vegetable fields, and compact with soil to avoid strong winds. Scratch the mulch. 4. Spread crop stalks or decomposed organic fertilizers, and keep them warm. In winter in garlic and spinach fields, sprinkling corn, wheat and other crop stalks or decomposed cow dung, chicken dung, etc., can not only play a role in heat preservation, but also promote early spring and win high yield. Or before the cold wave or rain or snow hits, you can use plastic film to cover and prevent the cold; after the cold wave, continue to strengthen the cover and cover to delay the freezing and thawing process and prevent the vegetables from freezing damage. 5. Strong plants. Before the arrival of cold currents, rain and snow, the leaves can be sprayed with chitin, alginic acid and other complete nutrient foliar fertilizers and plant-derived growth regulators.
