1. Selection of improved varieties: Corn seed is a high-yield basis and the key to production. The heritability of maize varieties directly affects corn productivity, stress resistance, and adaptability. Appropriate varieties can be selected according to local conditions, which can maximize the production of fine varieties and reduce the incidence of baldness. . 2, timely sowing: corn planting should take full account of the climate, variety and soil and other factors, corn hi warm, intolerant of low temperature, the whole growth period requires a higher temperature. Sowing too early, the long emergence period, low emergence rate, weak seedlings, serious physiological diseases; sowing too late, it will affect the late filling, resulting in too late. Spring corn is generally suitable for planting above 12°C in ground temperature, and the summer corn will be broadcast before the end of June. 3. Reasonable dense planting: According to climatic factors, irrigation conditions, soil fertility and species types, etc., a reasonable planting density is adopted so that the maize population has good ventilation and light transmission conditions, so that the corn individual can be well developed and the occurrence of corn baldness can be reduced. 4. Fertilization Irrigation: In the stage of growth and development of corn, it is important to fertilize and fertilize it. Based on the application of basic fertilizer, the principles of light weight, medium weight, and late supplement are applied. The main nutrient at the ear stage is nitrogen fertilizer. In the pollination stage, proper amount of jointing and panicle fertilizers are applied. If there is no rain after fertilization, it is necessary to timely guarantee the normal growth and development of corn for irrigation, thus reducing baldness. 5, emasculation: should be in the tassel has just extracted the parietal lobe has not been interspersed or septum, should not be too much, otherwise it will pollinate bad, resulting in empty ears. After detasseling, corn can reduce plant water and nutrient consumption, promote coarse and long ears, improve the upper air ventilation conditions, increase photosynthetic efficiency, and reduce the harm of corn. 6. Artificially assisted pollination: Under normal circumstances, artificial pollination is performed at about 10 o'clock in the morning at the flowering stage. If there is dew, it should be performed after the dew is slightly dry. The frequency of pollination is generally 2 to 3 times. 7, to prevent pests and diseases: The pests and diseases often appear on corn, according to different situations to prevent and control, can increase corn production.
