Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, in particular to an air-blowing precision hole fertilization device. Background Art

[0002] Precision hole fertilization technology is one of the key implementation methods of precision agricultural mechanical fertilization. During the sowing process of crops, whether fertilizer can be applied in a targeted and quantitative manner to the dense root area of ​​the crop is a key factor affecting fertilizer efficiency, promoting crop yields and reducing agricultural non-point source pollution. Currently available hole fertilization devices cannot accurately control the amount of fertilizer used. Too much fertilizer will cause seedling burns, and too little fertilizer will lead to insufficient crop nutrients. Secondly, the hole-forming effect of existing fertilization devices is unstable. When the hole-forming effect is poor, the fertilizer particles will be too dispersed at the roots of the crop, affecting the crop's absorption of nutrients and reducing crop yields. Therefore, it is necessary to invent a precision hole fertilization device to solve the above problems. Summary of the invention
