Vegetable management measures after the storm

From late July to early August, it is the main flood season. The storms are frequent. When the storm occurs, the leaves will be smashed, the vegetable seedlings will be washed, and the vegetables will fall and fall. The soil will be beaten by the rainstorm, and the roots will be forced to undergo anaerobic respiration. The resistance is greatly weakened, it is easy to infect various diseases, and vegetable production is seriously damaged. The proposed management measures are as follows:

1. Drainage and dewatering as soon as possible: The drainage and drainage ditches should be cleaned up in a timely manner, and the water in the vegetable fields should be drained as soon as possible to shorten the flooding time of the roots of the vegetables to prevent roots and roots. And properly raise the surface, digging deep drainage ditch to prevent the next round of heavy rain.

2. Strengthen field management: First, clean up the vegetables in time. Rinse the sludge splashed on the stems and leaves of the vegetables with clean water to avoid affecting the normal breathing of the leaves of the vegetables. It is best to use well water to not only lower the soil temperature, but also increase the oxygen content of the soil and improve the respiratory environment of the plants. Plants should be timely corrected, reduce each other's extrusion, and properly cultivate the roots; at the same time remove diseased leaves, old leaves, rotten leaves, rotten fruit to improve ventilation, reduce humidity, prevent pathogens. The second is to spray foliar fertilizer in time. Generally, 0.2% potassium dihydrogen phosphate + 0.5% urea solution can be used to make the vegetables quickly recover. The third is to scatter the wood ash in time. Spreading grass ash can absorb water, reduce soil moisture, increase nutrients, and improve soil environment. The fourth is to cultivate the loose soil in time. After the rain, the soil is compacted. When the soil is slightly dry, the soil is ploughed to enhance the permeability of the soil and promote the growth of the roots.

3. Timely prevention and control of pests and diseases: wind and rain is conducive to the spread of pathogens, accelerating the infection of diseases and insects after the rain, such as soft rot, root rot, and epidemics are all high-risk after rain. Prevention and control should pay attention to "preventing the main", grab the rain gap and spray some preventive fungicides that can cure fungi and bacteria in time, such as killing.

4. Grab and replant early: When the storm comes, the mature or soon-to-mature vegetables should be harvested early, thus reducing losses.
