Deep application of chemical fertilizers can be divided into three categories: deep application of bottom fertilizer, deep application of fertilizer, and deep application of fertilizer. The reason for the deep cultivation of chemical fertilizer is that according to the fertilizer requirement and soil properties of the crop, the formula fertilization technology and the fertilizer rhizosphere effect principle, the fertilizer is applied to a certain depth of the plough layer to facilitate better absorption of the crop, reduce the volatilization of the fertilizer, and improve the utilization rate of the fertilizer. A fertilization technique for the purpose.

 

First, the deep fertilizer

 

There are two methods for deep application of bottom fertilizer: one is to first plough and then plough, and the other is to apply fertilizer to the pear ditch while ploughing.

 

Second, the application of fertilizer

 

When the fertilizer is applied deeply, it is required to form a certain thickness of more than 3 cm in the fertilizer and fertilizer to meet the demand of nutrients in the growth of the seedlings, and avoid the danger of burning seeds and seedlings.

 

Third, the application of fertilizer

 

The top dressing is about 10-20 cm on both sides of the crop line , and the depth should be 6-10 cm wide and 3 cm or more. Pay attention to the soil after fertilization. Chemical fertilizer deep ploughing can be divided into three categories
