First, strengthen the management of exposed vegetables in open areas and rationally harvest damaged vegetables. Vegetables cultivated in the open field must be harvested in time after the disaster. After the frozen vegetables have been harvested, they must not be eager to melt. To make them thawed slowly, they can still maintain a certain amount of commercial value. For vegetables that have not yet reached the harvest stage, field plant management should be strengthened, such as removing diseased leaves, rotten leaves, pruning, fertilizing, and paying attention to disease prevention, etc., to gradually restore growth and reduce losses. For frozen vegetables, remove them in time. Second, remove snow in a timely manner and reinforce protective facilities. In order to reduce costs, most peasants use simple materials such as bamboo and wood to build sheds or greenhouses because of their simplicity. Due to poor support, most of the collapses in this snowstorm caused the greatest loss per unit area. It is necessary to promptly remove snow from the shed area, reduce pressure on the shed, and increase the light intensity in the shed. Reinforce the strength of the shed by using steel wires, adding temporary supports, etc. Third, improve the insulation capacity of the protection facilities. At present, the main areas for planting are fruit and vegetable crops, and fruit and vegetable crops in open fields, which are greatly affected by low temperatures. It is recommended that the temperature be guaranteed by covering the film in the shed, making temporary fires, and smoking fumes. Power-filled areas can increase the power light-up measures. As long as there is the sun, we must open the straw curtain in time. Ventilate as much as possible to reduce humidity at noon temperature. Fourth, the production of sprouts. In cities where the disaster is most severe, transportation is difficult to recover, and the vegetable market supply is tight, nearby farmers, agricultural enterprises, and qualified science and technology parks can be launched to produce a variety of sprouts. The Institute of Vegetables and Flowers of the Chinese Academy of Agricultural Sciences can provide related production technologies. V. Adjust the planting plan in time. (1) After the end of the snowfall in the affected area, after the temperature rises, the fast-growing leafy vegetable crops such as cabbage, spinach and lettuce can be quickly planted. The large number of long-distance transport of these leafy vegetables is not appropriate. (2) In the unaffected areas, at least 5%-8% of planting area may be considered for expanding production plans for spring and summer fruit vegetables (capsicum, eggplant, tomatoes, cucumbers, etc.). (3) In areas where the nursery is seriously affected, a concentrated nursery can be organized to protect the cultivated area of ​​fruit and vegetable crops in spring greenhouses and spring dew.
