During the growth of corn, heavy rains and windy weather often occur, which may lead to different degrees of lodging. Appropriate remedial measures should be taken after the lodging of the corn to promote the normal growth and development of the corn and reduce the adverse effects on the yield. 1. After the heavy rain, the ground drain should be dredged in time to eliminate the accumulated water in the field and reduce the soil moisture. 2. For corn with lighter lodging, there is no need to support it, because the plants have strong self-regulation ability. Generally, as the plants grow, they will naturally stand upright, and the spatial layout of stems and leaves will tend to be reasonable. 3. For the more serious lodging, you can use the artificial method to gently straighten the plant when the ground is slightly dry after the rain. The first and second sections of the base of the corn stalk are relatively fragile, and some of the roots are damaged. When it is straightened, it is necessary to prevent breakage and increase root injury. It is best to work with two people, one of them catching the corn plant and gently pulling it up from the upper part, and the other person is cultivating the soil at the root.
