| 摘 要： | 在内蒙古、新疆等大型农场,随着大马力拖拉机的增加,中小型小麦免耕播种机已经不能满足动力发展的需要,限制了保护性耕作的推广实施,急需研究与大马力拖拉机配套的大型免耕播种机。本文设计了2BMG-24型小麦免耕播种机,采用控制式密齿型排种器、波纹圆盘和双圆盘组合式开沟施肥播种单体,实现了精少量排种、破茬开沟和种肥分施的小麦免耕播种。田间试验表明:播种深度合格率为91%;排种均匀性变异系数为28%;种子破损率为0.1%。初步田间试验表明该机作业性能与国外同类产品相当。

| Abstract: | Medium-small no-till wheat planter hasn't already satisfy power need with the development of high-power tractor in the Mongolia and Sinkiang large farms,which restricted the application of conservation tillage.Therefore,it is necessary to study the large no-till planter matching with high-power tractor.Adopted the controlled flume dense dentiform seed meter to perform precision metering,the 2BMG - 24 no-till wheat planter was designed.Furthermore,the wavy disc coulters were used to cut stubble for sowing,an... |
