【摘要】 在东北地区垄作栽培制度下,高留茬或秸秆覆盖耕播是保护性耕作的主流模式[1]。为此,以承担农业部2004年保护性耕作技术创新课题—东北冷凉风沙区垄作保护性耕作技术的试验研究为契机,以辽宁省为试点,进行了东北垄作滚动圆盘式耕播机的技术创新。经2006-2007年春播田间试验,效果显著。通过对这种机型的工作部件与整机进行性能分析与试验研究,表明这种机型适于在东北地区垄作栽培制度下免耕播种作业推广应用。更多还原

【Abstract】 High-residue conditions till plant which on the basis of the ridge cropping system is the main mode of the conservation tillage in the North-East area of China.We developed the model 2BG-2 rolling disc type till-planter,the field test of spring sowing in 2005 and 2006 indicated that this till-planter worked well.This paper dealt with the function analysis and the test of working parts and whole machine of rolling disc type till-planter.This machine could be used in the conservation tillage of the North-East area of China.更多还原
