摘要
对4种尖头型免耕播种开沟器的工作性能进行了测试，分析了开沟器的工作阻力和对种行土壤物理特性的影响。试验结果表明，除宽翼型开沟器不适合免耕播种要求外，其他3种均可基本满足要求。
The working performances of four kinds of typical tine furrow openers weremeasured on no-tillage soil mulched with wheat stubble. The working force of furrowopeners and its effects on the physical properties of soil were analyzed. The experimentresults showed that the four types can all work properly on no-tillage soil except thewide-winged one.
