After maize emerged, the primary roots were few and the ability to absorb nutrients was weak. The use of a quick-acting fertilizer as a seed fertilizer had a good effect on the growth and development of seedlings, especially the plots with less basal fertilizer. Suitable fertilizers for fertilizers, such as: 1. Nitrogen fertilizer Under the conditions of low basal fertilizer application or thin soil, the use of nitrogen fertilizer as a seed fertilizer has a significant effect on yield increase. In nitrogen fertilizers, calcium ammonium nitrate, ammonium sulfate, ammonium chloride can be used as a fertilizer, but the amount should be noted. 2. Phosphorus and potassium fertilizers Phosphorus and potassium fertilizers in corn seedlings have good effects on growth, and they are high in seedlings, large in leaves, and robust in growth. The application of various phosphate fertilizers as seed fertilizers are effective. The quick-acting superphosphate and heavy superphosphate are most suitable for corn seed fertilizers. In areas with low potassium, it is necessary to add potassium fertilizer to corn seed fertilizers. It is best to use potassium chloride. Or potassium sulfate. 3. NPK combined application The application of N, P and K fertilizers as seed fertilizers was more effective than that applied alone. According to the experiment, the single application of nitrogen fertilizer as an average seed yield increased by 4.2%; the single application of phosphorus fertilizer as an average seed yield increased by 2.8%; and nitrogen, phosphorus, and potassium fertilizer increased the yield by 12.2% with cooperative seed fertilizer.
