The lighter-removing corn does not need to be supported, and the plants have strong self-regulating ability. As the plants grow, they will naturally stand upright. For the serious lodging, when the ground is slightly dry after rain, the artificial method is used to straighten. It is best to operate together. One of them catches the corn plant and pulls it up from the upper part. The other person cultivates the soil in the root. For the broken plot of the stem, the broken plant should be removed from the field as soon as possible to avoid decay and affect the growth of normal plants.
Timely fattening, the corn after lodging is poor due to photosynthesis, physiological functions are disturbed, affecting growth and development. For a field that only catches the fat once, you can catch another fat. If the first top dressing does not apply phosphorus and potassium fertilizer, phosphorus and potassium fertilizers should be the main ones. The first time the topdressing fertilizer has applied phosphorus and potassium fertilizer, it should be combined with the large flare period of topdressing, and the application of urea is 15~20 kg to increase the output.
Pay attention to the prevention and control of pests and diseases, and the disease is more likely to occur after the lodging of corn. Pay attention to the treatment. For leaf disease, with 70% thiophanate 800 times, 500 times, or 50% carbendazim, chlorothalonil 75%, or 300 times spraying, every 7 to 10 days, and even spray 2 ~3 times.
Other farmers have suggested whether other crops can be destroyed. It is definitely not feasible to do so. Before it is determined that corn plants are incurable, they should not give up. Destruction is a bit blind and should be actively taken to remedy.
