As the temperature rises, the peasants have set off a ridge of spring ploughing and how the fertilization of corn has been plaguing farmers. Reasonable fertilization of corn should grasp the following technical points:
1, deep fertilization 10-15 cm, to ensure that the fertilizer is isolated 8-10 cm, to avoid burning and burning phenomenon. Linyi Fertilizer Network Copyright
2. Determine a reasonable proportion of fertilization. That is, the ratio of nitrogen, phosphorus and potassium is applied to balance fertilization. Firstly, according to the law of corn growth and fertilization, the fertilizer needs more nitrogen and potassium during the growth period, and less phosphorus. Nitrogen and potassium utilization rates are higher, and phosphorus utilization rate is lower. In the fertilization, focus on nitrogen supplementation, appropriate amount of phosphorus and potassium. Secondly, fertilization is carried out according to the soil fertility condition and the fertilizer effect condition, and the soil test results are used as the basis of fertilization to determine the fertilization ratio.

3. Determine the reasonable amount of fertilization. The fertilization amount should be determined by soil fertility and yield, and the amount of fertilization should be determined by the soil test results as the fertilization basis. Linyi Fertilizer Network Copyright
4. Fertilization method. The combination of base fertilizer and top dressing ensures the nutrient supply of corn during each growth period, and strives to make each fertilization reasonable and effective, and improve fertilizer utilization. Linyi Fertilizer Network Copyright
5. Take a reasonable fertilization method. The ridge-side cultivation method should first plough a plough, and apply the fertilizer in the ditch to ridge again. The plot of the scorpion scorpion will be ridged before the arable land, or it can be combined with the machine to ensure the isolation of the seed fertilizer, and the seed fertilizer is separated by 8-10 cm to avoid burning and burning seedlings.
