First, clean up the gully and eliminate stagnant water: After the vegetable field is flooded, the toxic substances increase and the root activity declines. After the flood recedes, it is necessary to quickly ditch, reduce the groundwater level, eliminate toxic substances, and promote root growth. Temporarily loosen the kneading surface, accelerate soil oxidation, and promote the growth of vegetables.

Second, shading sunscreen, prevention of wilting: for some of the more heavily flooded but roots still absorb the ability of eggplant, pepper, melon and other vegetables can be cut off by the use of cut off the top of the dense branches or shades of the sun, to prevent cockroaches After the sun exposure, reduce transpiration and prevent wilting.

Third, strengthen the fertilizer, foliar spray fertilizer: after the vegetable field is flooded, nutrients are easy to lose, so it should be timely applied nitrogen, phosphorus, potassium fertilizer and other compound micro-fertilizer, can be combined with cultivating. Fertilization should be careful not to be overweight or excessive, otherwise it will easily cause fat damage. It can also be used for top dressing, and the leaves are sprayed with potassium dihydrogen phosphate or other compound micro-fertilizer.

Fourth, prevention of pests and diseases, control of the disease: when the leaves are slightly dry, spray immediately on fungi and bacteria are effective to prevent fungicides, preferably use Bakken (40% suspension ) and copper oxychloride (30% suspension ) Mixing to form a film on the wound and leaf surface to prevent the invasion of germs. Prophylactic and therapeutic fungicides can also be selected for different crop diseases. Pay attention to monitoring the occurrence of pests and timely symptomatic medication control.

Fifth, timely replanting, rushing to plant: for the seriously affected, roots have died of vegetables in time to clear the pastoral, fine soil preparation after disinfection, re-sow vegetables or replant other economic crops.
