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。
In order to reduce the labor intensity and improve the economic benefits of planting tobacco, the application effect of M-type wide ridge double-row planting mode was studied by field plot test. The results showed that compared with single ridge single row planting mode, the middle leaf area increased by 4.9% and the upper leaf area increased by 26.19% Save 22.2% of the film, and facilitate the mechanized operation, which is conducive to the organic combination of agricultural and agronomic practices. The planting mode yields an average of 149.5 kg / hm2 and a cost-saving effect of 5 426.57 yuan / hm2, and can also increase the reducing sugar, The total sugar, potassium content, the tobacco chemical composition more coordinated, is a new planting mode, the promotion of broad prospects for application.
