摘要 为验证可清除播种行麦秸的玉米灭茬清垄免耕播种机在预防二点委夜蛾为害中的实际应用效果，以传统玉米免耕播种机为对照，进行了2种播种机对幼虫为害防控的田间试验。结果表明，灭茬清垄播种机，可使播种带15 cm宽度范围内无麦秸覆盖，玉米出苗后不被麦秸围棵，破坏了二点委夜蛾的适生环境，对幼虫为害的防效可达100%;而传统玉米播种机，播种带宽度仅0～7 cm，仍会有麦茬麦秸覆盖其中，对二点委夜蛾危害的预防效果较差。

Abstract In order to verify the practical application effect of no？鄄tillage maize planter with stubble cleaning in preventing the harm of Athetis lepigone，field experiments on larval damage control of two kinds of seeders were carried out with traditional no？鄄tillage maize seeder as control. The results showed that the stubble clearing seeder could make the sowing belt 15 cm wide without wheat straw mulching，and maize could not be enclosed by wheat straw after emergence，which destroyed the suitable environment of Athetis lepigone，and the control effect on larvae could reach 100%. However，the traditional maize seeder，whose sowing bandwidth was only 0-7 cm，will still be covered with wheat stubble，which had poor prevention effect on th...
