Abstract: Aiming at the problem of low intelligent degree of organic fertilizer fertilization, an intelligent fertilizer application machine is developed. The power part of the whole machine adopts the combination of hydraulic system and mechanical system, and the control system adopts FPGA technology. Using the data processing in the early stage, the relationship between the amount of fertilizer application, the width of fertilizer application and the gear position of the fertilizer delivery mechanism, the opening of the fertilizer control gate and the angle of the fertilizer drop point control cover and the correlation between the amount of fertilizer application and the width are obtained, and the variable adjustment and visual control of the amount of fertilizer application and the width can be realized, and the size of the width can be predicted according to the amount of fertilizer application. The results show that the program of the control system is stable and reliable, the error of fertilizer application amount is 2.58%, the error of fertilizer width is 3.53%, and the operation effect is good, and the technical indexes meet the agronomic requirements.
