Empty stalks and lodging have common causes, and there are special reasons for different situations in different years. Therefore, precautions should be taken according to local conditions. First, reasonable close planting of corn for proper planting can make full use of light energy and fertility, and good ventilation and light transmission within the group are the main measures to reduce corn stalks and lodging. The adoption of large and small ridge cultivation has a certain effect on improving the lighting conditions in the population, not only reducing the rate of empty culms, but also reducing the lodging caused by insufficient roots, shallow distribution, and excessive internodes due to lack of light. Second, we must provide reasonable and timely supply of fertilizer and fertilizer water, so that the ear of the differentiation and development of adequate nutrition conditions, and pay attention to the application of nitrogen fertilizer, combined with phosphorus, potassium fertilizer. From jointing to flowering, it is a crucial period for the differentiation and establishment of pollination and fertilization. The timely supply of fertilizer and water can promote the differentiation and normal fruiting of the ear. For soils with low soil fertility, fertilizing materials should be added and topdressing should be applied in the early stage. For soils with high soil fertility, it should be pursued in stages. Retrieving in the middle and later stages has a positive effect on preventing empty stalks and lodging. Seedlings should pay attention to the seedlings, to promote the roots under the bar, the base of the stem section shortened; excessive rain, pay attention to row ventilation. Two-and-a-half months before and after corn tassels require more water, timely irrigation, not only can promote the development of the ear, but also reduce the emergence of male and female flowers, conducive to pollination and reduce empty stalks. Thirdly, we must select suitable varieties for local conditions and select hybrids and superior varieties suitable for local natural conditions and cultivation conditions. For soil with fertile soil and high cultivation level, the dentate species with high yield performance is selected; for land with low soil quality and low cultivation level, hard-adapted or semi-dentate species with strong adaptability are selected. In windy areas, we choose dwarfs, short internodes at the base, strong root systems, and strong resistance to lodging. In addition, we must strengthen field management, control seedlings to promote seedlings, make seedlings neat and robust, timely control of pests and diseases, and artificial pollination also have the effect of reducing empty stalks and preventing lodging. Fourth, to control large seedlings and promote seedlings at the seedling stage so that the seedlings are tidy and healthy, such as low temperature in spring and accompanied by drought, directly affect the growth of roots. Reasonable cultivation measures should be taken to improve soil structure, restore soil fertility, and suppress weeds. Reduce the occurrence and development of pests and diseases, improve the distribution of maize roots, and promote the growth and development of corn. In addition, pests and diseases should be prevented and treated in a timely manner. Artificially assisted pollination can reduce the impact of empty stalks and lodging.
