According to the characteristics of forage short season cotton continuous cropping mode in coastal saline alkali land, a new intelligent cotton planter based on Beidou navigation was designed. and the seed is made, and the layering is fertilized. The machine can complete the unmanned Beidou navigation, sowing belt cleaning, layered fertilization under seed, seed and fertilizer isolation, intelligent precision sowing, seed and fertilizer isolation, soil covering and pressing, surface shaping and other processes at one time. Field experiments are carried out with the machine. The results show that the accuracy of the link line and the straight end of the broadcast line are accurate, which improves the accuracy of the link line and the straightness of the broadcast line, and the average depth of the broadcast is 2.8 cm; The qualified rate of sowing depth was 92.5%; The accuracy of connecting line spacing is 1.2 cm; The straightness of sowing line was 0.8 cm, and the land use efficiency was increased by 5%. It lays the foundation for the follow-up standardized operation in the field, realizes the accurate control of sowing and fertilization, and saves seed and fertilizer.

In order to ensure that the amount of organic fertilizer applied in the field is accurately controllable and meets the needs of field crop growth, a solid organic fertilizer application control system based on BP neural network algorithm is designed. The supporting equipment of the system adopts a solid organic fertilizer spreader with chain plate and fertilizer baffle to control the amount of fertilizer. The control system is developed based on supervisory control and data acquisition (SCADA), and the human-computer interaction is realized by the touch screen. The basic data of the control system is provided by the actual demand for basic fertilizer in farmland and input into the system through the input box. According to the speed of the vehicle, the momentum BP neural network algorithm is used to first control the opening size of the fertilizer blocking device and provide an input value for the rotating speed control of the fertilizer chain plates. Finally, the elastic BP neural network algorithm is used to control the rotating speed of the fertilizer chain plates. The experimental results show that the control system can change the opening size of the fertilizer blocking device and the speed of the chain plate of the fertilizer spreader in real time according to the set basic fertilizer demand and the traveling speed of the vehicle, and the control deviation of the fertilizer amount is less than 9%.
