摘　　要：为降低劳动强度,提高种烟的经济效益,采用田间小区试验的方法,研究了M型宽垄双行种植模式的应用效果。结果表明,与单垄单行种植模式相比,打顶期M型宽垄双行种植模式中部叶面积增大4.9%,上部叶面积增大26.19%,通过地膜半幅覆盖提高人工覆膜效率,可节省地膜22.2%,而且便于机械化操作,有利于实现农机与农艺的有机结合;该种植模式平均增产149.5 kg/hm2,节本增效5 426.57元/hm2,而且能提高烤后烟叶的还原糖、总糖、钾含量,使烟叶化学成分更加协调,是一种新的种植模式,推广应用前景广阔。Reducing labor intensity and increasing economic benefit of tobacco-growing were the purpose of this study.A field experiment was conducted to study application effects of M-wide double ridge on tobacco production.The results showed that the upper leaf area improved by 26.19%,while the middle leaf area improved by 4.99% in topping stage.M-ridge faciliated mechanical operation and improved the efficiency of mulching,and saved plastic film by 22.2%.The yield increased by 149.5 kg/hm2 and saved 5 426.57 yuan/ha.This cropping pattern caused reducing sugar,total sugar,potassium and made chemical composition more harmonious.It was a new cropping pattern,with broad prospects of popularization and application.
