Comprehensive winterization and disaster reduction technology for vegetables

1. Cultivate soil to increase farmyard manure. Warm farmhouse fertilizer such as pig cow dung or earth miscellaneous fertilizer, cultivating in the roots of vegetables, can increase the root soil temperature 2 ~ 3 °C, should be carried out on a sunny day, per acre Shi 1000 ~ 1500 kg. In combination with cultivator, the use of fine soil to cultivate the soil around the root can loosen the soil, increase the soil temperature, and protect the root directly.

2. Add foliar fertilizer to ensure normal vegetative growth. Foliar application of 1-2 times 0.2% potassium dihydrogen phosphate solution on the vegetables in the shed to supplement the plant nutrition and enhance the cold resistance.

3. Adding a cover reduces wind and cold damage. Covering vegetables and vegetables with agricultural film or wheat straw, use 100-150 kilograms of straw per acre. Sprinkle it sparsely. Do not cover all vegetables to avoid affecting photosynthesis.

4. Sunny days open trenches to prevent waterlogging. Clean up the ditch immediately after the snow, remove the water, increase the vitality of the roots, and prevent the occurrence of waterlogging. Remove greenhouses and snow on both sides in time to prevent absorption of large amounts of heat while melting to reduce the temperature inside the shed, and drain water to prevent waterlogging.
