Corn is one of the crops that require more fertilizer. If base fertilizers are used infertility during the growth period, the amount of topdressing fertilizers is small, so it is difficult to meet the premature deferment of defertilization in the late growth and development of corn, which will seriously affect the yield and quality of corn and reduce the benefit of cultivation. In the late growth period of maize, it refers to the time from corn pollination to maturity, which is the key period for the formation of corn economic output. During this period, the dry matter formed by corn accounts for more than 1/2 of the total biological output, even reaching 2/3. . If corn is improperly managed in the later period of fertility, it will often lead to premature degeneration of fat, lodging, serious diseases and insect pests and other phenomena. The specific prevention measures include the following four points: (1) Rational fertilization: Fertilization is to meet the demand of corn for nutrients, and to ensure that there is no defertilization in the later period, so that it has enough green leaf area for photosynthesis. (2) Reasonable irrigation: Before maize has sufficient water supply before grouting and grouting, the lack of water will affect the photosynthesis of maize and the growth of roots, affecting the quality of grouting. (3)Preventing lodging: The late corn lodging will cause serious reduction of production and quality of corn, preventing lodging to effectively combine top dressing, grouting, and cultivating soil, so as to enhance the absorption capacity of roots for nutrients, promote the growth of aerial roots, and enhance the lodging resistance of plants. . (4) Pest Control: Corn borer is a major pest in the late growth and development of corn and should be carefully controlled.
