   The following three measures should be taken immediately to reduce losses:
First, the plant is rectified and harvested in time. For lodging plants, they can be classified according to the growth process and lodging. If the corn has already fallen into the maturity period, it should be immediately harvested, aired, and stored. For the corn that has entered the end of the filling stage or enters the maturity stage, if the plant falls and the stem is not broken, the plant should be immediately replenished and matured. Harvest together. The specific method can be used to tie the fallen plants with the surrounding plants that are not laid down by straw or rope, so as to avoid the mildew caused by the touch of the ears.
The second is to clear the ditch drainage, clean the leaves, and top dressing. Mainly for waxy corn, sweet corn, and high mountain corn in the vegetative growth period. After the lodging occurs, the corn seedlings should be uplifted in time, and the leaves of the seedlings should be sprayed with water to increase the light transmission of the leaves. At the same time, the urea 0.5%+ potassium dihydrogen phosphate 0.2% page should be sprayed in time, usually twice in succession, 7 days apart . When working, be sure to completely dissolve and mix urea and potassium dihydrogen phosphate to avoid excessive local concentration and cause burning of the outer leaves, which will increase the degree of disaster.
The third is to strengthen the prevention and control of pests and diseases. The current rainfall has little effect on the yield of corn to be harvested in a large area, but the waterlogging after the accumulation of water may adversely affect the crops such as sweet potato and soybean. Therefore, it is necessary to strengthen the prevention and control of pests and diseases, which is conducive to the crop growth.
