Smart management of vegetables after heavy rain
Conditions such as high temperature and humidity directly affect the yield and quality of open-field vegetables, and cause varying degrees of harm to vegetables. In order to reduce the impact of heavy rains on vegetables and reduce vegetable casualties, we must deal with them in time to avoid losses. The following methods can help farmers reduce losses after rain.
1. After the rain, drain the rainwater from the vegetable borders in time, and irrigate them with small well water to reduce the soil temperature, increase the soil permeability and oxygen content, and keep the vegetables in a normal breathing state.
2. For plots with low vegetable density, it is recommended to use a hoe to loosen the soil in time to dissipate soil moisture in time, enhance soil air permeability, and prevent the occurrence of rooting and vegetable soil-borne diseases due to large soil moisture.
3. For dense plants, use tools such as hooks or small hoes to loosen the soil in time to prevent soil compaction and improve the vitality of vegetable roots.
Fourth, try to straighten the plants that are skewed or adhered to the soil to reduce the rot and disease caused by mutual extrusion, so that the vegetables can grow normally.
5. After heavy rain hits, vegetable root system activity is weak, and its ability to absorb water and fertilizer is poor. It should be sprayed with Jia100 spray on foliage in time to enhance the ability of vegetables to absorb fertilizer and restore plant growth vitality.
6. In the seedling stage, spray anti-root and decay drugs, such as hymexazol or methfludioxonil or ethicin. In the growth period, spray anti-fungus and blight drugs, such as metalaxyl, carbendazim, etc. Thiophanate-methyl should be combined with bacterial drugs, such as Zhongshengmycin, Zhongshengtetramycin, etc., to prevent rot and disease infections caused by various blights and bacterial diseases.
7. Rush to harvest and broadcast at the right time to minimize production losses. The mature vegetables should be harvested in time to reduce losses. In case of heavy rain and flood-affected plots, seedlings should be pulled in time, and the next crop should be arranged quickly. Heat-resistant amaranth, water spinach, spinach, pakchoi and other fast-growing leafy vegetables can be planted in the summer and autumn off-season.
