Comprehensive technology for antifreeze and disaster reduction of winter vegetables
(1) Function and use
By increasing the application of farmyard manure and foliar fertilizer, the soil temperature of the roots is increased and the cold resistance is enhanced.
(II) Technical Introduction
1. The soil is cultivated by the roots of the soil. Use warm farmyard manure such as pig manure or soil fertilizer, and cultivate the roots of the vegetables to increase the soil temperature of the roots by 2 to 3 °C. It should be carried out on sunny days, and 1000-1500 kg per acre. Combined with cultivating, using fine soil to cover the roots, the soil can be loosened, the soil temperature can be increased, and the roots can be directly protected.
2. Adding foliar fertilizer to ensure normal vegetative growth. Foliar application of 0.2% potassium dihydrogen phosphate solution to the vegetables in the shed will not only supplement the plant nutrition, but also enhance the cold resistance.
3. Add a cover to reduce wind damage. Cover the vegetables and vegetables with agricultural film or wheat straw, use 100-150 kilograms of straw per acre, and sprinkle it. Do not cover all the vegetables to avoid affecting photosynthesis.
4. Open the ditch on the sunny day to prevent waterlogging. Immediately after the snow, clear the ditch, remove the accumulated water, improve the vitality of the root system, and prevent the occurrence of waterlogging. Timely clear the greenhouse and the snow on both sides to prevent a large amount of heat from being absorbed during melting and reduce the temperature inside the shed, and ditch drainage to prevent waterlogging.
