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.
