Background technique

Cotton is one of the main crops produced by human beings. It can be made into fabrics of various specifications and is suitable for making all kinds of clothes, furniture cloth and industrial cloth. Fertilizers are used for treatment to supplement the nutrients needed for cotton growth. Fertilizers are commonly used in agricultural production; however, different fertilizers have different fertilization depths, or the same fertilizer has different fertilization depths, resulting in different effects, so it is necessary to layer fertilizers Fertilization can greatly improve the utilization rate of fertilizer, but the existing fertilization device has a single structure and can only apply fertilizer at a fixed depth, which cannot meet the actual demand. Therefore, we have invented a quantitative fertilization device for cotton planting.
