摘要
玉米免耕播种机是与玉米留茬免耕技术配套的播种机具。3年的大面积田间试验结果表明：使用玉米留茬免耕播种机播种能抵御春旱和季节性“掐脖旱”，提高产量15％～35％，增加利润约10％。使用玉米留茬免耕播种机还具有减弱水气蒸发、防止水土流失的作用。
No-tillage corn planter is an equipment in support of the technology of no-tillage corn planting. Results of the three-year experiment indicate： using no-tillage corn planter can effectively resist spring drought and seasonal dry situation, increase yield by 15%--35%, increase profit by 10%. It can also reduce water evaporation and prevent soil erosion.
