How to fertilize corn in summer?

How to fertilize corn in summer? Please introduce the method of summer corn planting and fertilization can refer to the following methods: first, avoid excessive fertilizer application. When some farmers grow summer corn, the amount of urea used is more than 50 kg per mu, which will lead to the decline of fertilizer utilization and corn quality, and will pollute the soil. In order to improve the yield and quality of corn, we should not only increase the amount of fertilizer application, but also improve the fertilization method and improve the utilization rate of fertilizer. Second, avoid the weight in front and light in the back. The fertilization method of heavy before and light behind will lead to the decrease of fertilizer utilization rate, sufficient fertilizer in the early stage, good corn growth but excessive vegetative growth, closed field, delayed reproductive growth period, poor growth or even de-fertilization in the later growth stage, and low corn yield. Third, avoid a single variety of fertilizer. Some farmers only use urea when fertilizing corn fields in summer, which replenishes nitrogen to corn and soil, but not phosphorus, potassium and other nutrients to corn and soil. This will result in a decrease in the number of grains per ear, 1000-grain weight, yield, lodging resistance, disease resistance and insect resistance of maize, which is prone to diseases and insect pests. Fourth, avoid burning seedlings caused by improper mixed sowing of seeds and fertilizers. First, the amount of fertilizer used is large, and the amount used per mu is often more than 7.5 kg. Second, improper application of fertilizer varieties, if the application of urea and other quick-acting fertilizer, the amount should be less than 5 kg per mu; if compound fertilizer is used, the application rate can be a little more. Third, because of the sowing machinery, the horizontal distance between the sowing belt and the fertilization belt is too close (less than 5 cm), which is easy to cause seedling burning. The distance between seed and fertilizer should be more than 10 cm. Click to get more corn planting techniques click to get more food crop planting techniques
