玉米垄作免耕播种机油耗试验与分析（Fuel Consumption Test and Analysis for the Ridge-till and No-till Corn Planter）
垄作 保护性耕作 播种机
2009/11/3
保护性耕作技术在我国垄作地区难以推广的主要原因是缺乏在有根茬原垄上确保播种质量的免耕播种机。针对以苗带浅旋处理玉米根茬为机理的2BML-2型垄作免耕播种机，进行了田间油耗试验。试验结果表明：在开沟器、覆土装置、镇压装置等部件工作参数一定时，影响播种机油耗的主要因素中，根茬处理装置的旋耕入土深度影响最大，其次是旋耕幅宽，然后是机组前进速度；在适合范围内，机组前进速度越大，油耗越小；本播种机能有效减少...
