1, as soon as possible to eliminate water in vegetable fields. To clear the ditch in time, lower the water level and eliminate stagnant water in the vegetable plot. 2. Timely repair of damaged greenhouses, nursery, irrigation and drainage facilities. Strengthen field management, normalize plants, and restore normal vegetable growth. 3, artificial water protection leaves. Submergence of vegetables will affect leaf respiration and photosynthesis, resulting in a large number of deciduous, fruit drop; After heavy rain without vegetables, the stems and leaves will be adhered to the ground and the pores on the leaves will be blocked, affecting the respiration, transpiration and photosynthesis. . In addition, the vegetable plants attacked by the heavy rain were blown, the stems and leaves were broken, the soil was compacted, and the roots were forced to undergo anaerobic respiration, leading to death. Therefore, immediately after the storm, artificial watering and watering should be organized to remove the sediment adhering to the leaves and leaves, so that the vegetables are in normal breathing state. 4. Do a good job of preventing and controlling post-disaster pests and diseases. Solanum species should focus on prevention and control of disease and bacterial wilt. The disease can be used 58% metalaxyl (drugs mildew) WP 600 times, 64% anti-virus WP 500 times spray; bacterial wilt can be used 72% of the agricultural streptomycin sulfate 4000 times, 77% can kill Wet powder 500 times spray control. Prevent and treat once every other week, even against 2-3 times. Leafy vegetables: The harvested vegetables were harvested on the market in batches and sprayed with chlorothalonil and carbendazim to prevent disease 1-2 times. 5. Encourage vegetable farmers to participate in steel shed insurance in agricultural insurance, and strive to minimize the damage caused by the disaster.
