Abstract: Objective In the light of the unscientific method of fertilization in the process of cotton planting, the traditional fertilizer application is large and the utilization rate is low, which causes soil pollution and so on.Method In combination with the agronomic characteristics of cotton planting, the fertilizer utilization rate and crop yield can be improved by reducing the fertilizer and using the fertilizer accurately.. In this paper, a cotton base fertilizer counter row delamination deep applicator has been developed. In order to combine the fertilizer reduction and efficiency with the mechanized fertilization of cotton, a kind of deep application of cotton base fertilizer mechanization based on the Beidou navigation technology was put forward, and the layered deep application of the base fertilizer in the direction of cotton planting was carried out. A delamination deep sizing machine for cotton base fertilizer was developed. Result The experimental results showed that the average fertilizer amount per mu was 21.4 kg, the coefficient of variation was 4.0%, and the amount of fertilizer was stable. In terms of fertilizer depth, the average depth of deep fertilizer was 19.8 cm, and the average depth of shallow fertilizer was 12.5 cm, which could effectively meet the actual production operation.Conclusion The machine was mainly composed of delamination fertilization device, soil covering device, fertilizer arrangement device, and deep walking wheel. The field test of the prototype used Beidou navigation tractor automatic driving system to carry on the deep application of fertilizer.
