玉米精量播种区段控制技术研究现状OA

This paper briefly describes the significance of precision planting section control technology of maize,and points out that precision planting section control technology is an effective means to save good seeds and improve yield,and an important way to realize seed saving and loss reduction in maize planting.The development process of section con-trol is summarized.Based on the section control process,the section control technology of precision planting is divided in-to three processes:seed implantation positioning,position relationship judgment and seed metering start and stop control.The main research contents and research process of the three processes are introduced.Based on the research at home and abroad,the main technical difficulties faced by section control technology are pointed out.Finally,combined with the current situation of maize planting in China,the development trend of maize precision sowing section control technology in China is prospected.
