With the increase of temperature, farmers have set off an upsurge in spring cultivation. How fertilize corn has plagued farmers. Reasonable fertilization of corn should grasp the following technical points: 1. Deeply apply 10-15 cm of fertilizer to ensure that the seed fertilizer is separated by 8 to 10 cm, and avoid burning seeds and burning seedlings. 2, determine a reasonable proportion of fertilizer. That is, the ratio of nitrogen, phosphorus, and potassium is applied to balance the fertilization. First of all, according to the laws of corn growth and fertilizer requirements, corn in the growth phase requires more nitrogen and potassium, less phosphorus. The utilization rate of nitrogen and potassium is higher, and the utilization rate of phosphorus is lower. Focus on nitrogen supplementation on fertilization, and appropriate phosphorus and potassium supplements. The second is to fertilize according to the soil fertility status and fertilizer effect status, and the soil testing results are the basis for fertilization and determine the fertilization proportion. 3, determine a reasonable amount of fertilizer. To determine the amount of fertilizer by using soil fertility and yield, the amount of fertilization should be based on the results of soil testing to determine the amount of fertilizer. 4, fertilization methods. The use of basic fertilization and top dressing combined with fertilization ensures the nutrient supply during each growth period of maize, and strives to ensure that each fertilization is reasonable and effective, and the utilization rate of fertilizer is increased. 5, take a reasonable method of fertilization. In the ridge-side cultivation method, a plow should be picked up first, and the fertilizer should be applied in the ditch and then ridged. The plots of stubborn lice will be ridiculed after spreading the fertilizers in front of the arable land. They can also be combined with deep rakes to ensure the segregation of seed fertilizers to achieve 8 to 10 cm isolation of seed fertilizers so as to avoid burning seed and burning seedlings.
