播种作为农业生产重要环节之一,控制播种深度一致性可有效改善作物萌芽情况和生长状态,实现节本增产。总结国内外播种机播种深度控制技术研究现状、主要控制装置研究形势,阐述播种深度控制技术中仿形技术特点,指出播种深度控制技术存在适用范围小,控制不及时的不足。结合农艺要求对我国播种机械的播种深度控制技术优化和发展进行讨论并提出建议。

As one of the important links in agricultural production,sowing can control the germination and growth status of crops and increase the yield.This paper summarizes the research status of planting depth control technology and the research situation of main control devices at home and abroad,and expounds the characteristics of profiling technology in seeding depth control technology,and points out that the seeding depth control technology has the disadvantages of small application range and untimely control.In combination with agronomic requirements,we discuss and make recommendations on the opt...
