The first is the selection of fine varieties. Choosing suitable varieties for high yield and high resistance suitable for local planting and dressing with new high fat film before sowing is one of the first measures to reduce the empty stalk of corn.
The second is the rational close planting. Different varieties have their own suitable planting density, generally better ventilation and light transmission in the field, higher light energy utilization rate, conducive to the formation of photosynthetic products, increase the nutrition of the ear, and promote the differentiation of the ear, so as to achieve multiple spikes, great mass, and high yield ;
The third is to strengthen field management. Appropriate application of fertilizers, organic fertilizers, balanced application of nitrogen, phosphorus and potassium fertilizers to achieve the combination of organic and inorganic fertilizers. In the maize seedling stage, strengthen management, control large seedlings, promote small seedlings, eliminate three types of seedlings, so that the maize population grows robust and neat. In the flowering pollination period, in the event of rainy weather, we must try to artificially pollinate and spray the strong spearhead on the foliage, which can improve the quality of crops subjected to pollination, fertilization and grouting, and increase the grain weight.
