Suggestions on Restoring Production of Vegetable Base after Flood and Waterlogging Disasters
1, row out. Clear the ditch and drain away the stagnant water in the vegetable field as soon as possible to reduce the water level and prevent the waterlogging of the roots of the crops.
2, dehumidification. After the heavy rain, greenhouse vegetables should be ventilated and ventilated in time to remove diseased plants and diseased leaves, reduce humidity and reduce the source of disease, and prevent the spread of diseases.
3. Strengthen the management of field vegetable lands. For vegetables with market value, it is necessary to promptly catch up and reduce losses. For fruits and vegetables that are affected by heavy rain, flooded fruits and vegetables are timely rectified and ribbled, and foliar sludge is washed away, with dead yellow leaves, diseased leaves, and diseased fruits removed. Supplement fertilizers in time to promote the development of new roots and new leaf growth. The cultivating soil in the cultivating soil loosens the soil permeability, so that the vegetables in the land can be restored as soon as possible.
4, prevent withered. The roots of vegetables that have been flooded for long periods of time have become rotten and damaged. When the rain is clear, it can easily cause death. Therefore, it is necessary to pay attention to proper shade and to reduce the death of withering.
5, prevent diseases. High humidity in rain and high temperature after rain will cause disease epidemics, soft rot of leafy vegetables, downy mildew, melons and vegetable diseases, gray mold, wilt disease, eggplant early blight, gray mold, wilt disease, etc. Diseases are prone to occur, and targeted prevention and treatment should be carried out after clearing.
Second, ploughing and preparing for the next season
For the heavily damaged or unreceived plots, drain water, resume production as soon as possible, and alleviate the shortage of vegetables in the market.
1, rush to plant fast-growing vegetables. Timely drainage of stagnant water, rush to broadcast a batch of fast-leaf lettuce, such as cabbage, seedling cabbage, leeks, leeks, etc., in the production process should pay attention to the management of water, using shade net cover to prevent heavy rain, high temperature And drought.
2, timely arrangements for gargle, grab a batch of autumn vegetables.
(1) Autumn cucumber: sowing before the beginning of autumn, using live broadcast, 3000-3500 points per acre, double plant per hole. Management points: To ensure the water supply during the seedling stage and the sapling stage, shoot side branches within five knots, and leave one melon and one leaf topping for five or more branches.
(2) Qiudou beans: sowing before the beginning of autumn (seeding after the beginning of autumn will reduce production 20% -30%), using live, about 3000 points per acre, double plant per hole. Management points: Pre-seedling, timely supply of water to ensure that the seedlings are neat.
(3) Autumn beans: sowed before the beginning of autumn, using live broadcast, about 4000 points per acre, double plant per hole. Management points: After the first real leaf is developed, water and fertilizer management will be strengthened.
3, take heat-resistant cultivation, anti-season production of cool vegetables.
Using shade nets to cover, in the greenhouse or small arch shed seedlings, all seasons onions, radishes and other seasonal off-season vegetables, these vegetable production techniques require high, but good efficiency.
4, to strengthen the production of information organizations, as soon as possible to prepare the early autumn vegetables or early spring production.
Qiuyu vegetables include pepper, Chinese cabbage, Chinese red cabbage, radish, cabbage, cauliflower and so on. The peppers are planted in mid-July and planted in early August; the Chinese cabbage is planted in mid-late August and harvested before heavy snowfall; the red vegetable pods are sown from the end of August to the beginning of September; the radish and carrots are planted from August to September; and the cabbage is sown from July to August. Cauliflower, broccoli sowed in July-December; early spring cabbage seeded at the end of September; late spring cabbage seeded at the end of October.
