Cold-proof measures for winter and spring vegetables

In winter and spring, vegetables are often exposed to cold weather, frost, frost, and other bad weather. Inadequate protection often leads to greater economic losses. Here are some ways to prevent cold. 1, nitrogen control: the seedling stage to reduce the amount of nitrogen fertilizer, avoid partial nitrogen fertilizer, so as not to plant young, cold resistance is poor. Top dressing is early, in order to promote vegetable seedlings. Before applying low-temperature nitrogen fertilizer, it is advisable to spray 0.2%--0.3% potassium dihydrogen phosphate 1--2 times. 2, fertilization: the use of sunny, with cattle, pig manure or compost and other warm fertilizer 100 kg - 150 kg, applied to the root of the vegetable locust, you can increase soil temperature 2 °C - 3 °C. 3, soil: combine with cultivator before freezing, the smashed soil cultured in the vegetable roots, not only can loosen the soil, but also can directly protect the root system, but the cultivator depth of 7 cm -10 cm is appropriate. 4, smoked smoke: with weeds, straw, litter and other stacked piles, in addition to the ignition, the other with dry, fine yellow mud lightly compacted, before the advent of frost, in the upper ignition of the ignition of smoke. If there is an open flame, then seal it with fine soil, so that it can not only disperse cold currents, but also make fire and soil. 5, spray petroleum steam suppressant: in the cold before the advent of 3--4 days selected sunny plants spray 30--40 times the oil suppressant, that is, in the leaves can form a layer of invisible cold film, is beneficial to reduce the blade The transpiration effect protects the body temperature of the vegetables and prevents cold. 6, pouring feces: Frozen in front of every 667 square meters with 400 kg of faecal water - 500 kg, splashing water to freeze, reduce the cold. 7, winter irrigation: 1-2 days before the cold invasion, the weather is sunny and watered. After freezing, it must be noted that after the cold has passed, the weather has indeed warmed up, and the soil temperature has risen to 2°C - 3°C. Only when the soil and vegetables have been thawed, can it be done, otherwise it will aggravate the freezing injury. Filling and pouring in winter irrigation, the field water can seep through the day. After the irrigation, seize the favorable opportunity to carry out loose soil insulation. 8. Sprinkle ash: Before the onset of low-temperature freezing damage, sprinkle a thin layer of hull ash or ash on the vegetables, or sprinkle 50 kg of ash or ash on the vegetable line. This can prevent cold and freeze, increase fertilizer, and also cross the cross. Root rot of flowers family has better control effect. 9. Coverage: In the afternoon before freezing, sparsely cover rice or vegetables with straw, etc., and must not cover all vegetables to avoid affecting photosynthesis. Covering 100 kg of straw, etc. per 667 square meters. 10. Precipitation: For high-groundwater table crops such as cold-stained and low-lying sorghum, pay close attention to opening the “three-channel” to ensure the openness of the gutter, in order to lower the water level, eliminate waterlogging, increase soil temperature, and promote vegetable growth.
