    Effects of the “Straw Mulching after Plastic Film Uncovered” Technique on Growth, Yield, and Quality of Flue-cured Tobacco

    • 摘要: 研究了“前膜后草”覆盖栽培对烤烟生长及产质量的影响。结果表明,“前膜后草”覆盖栽培方式在烟株生长前期能提高地温,促进烟株的早生快长,减少早花率;成熟期能保持土壤水分,降低地温,保持烟株的根系活力,提高上部叶的田间耐熟性;同时明显提高烤烟的产量、产值,对提高烟叶还原糖、降低烟碱含量也有一定的效果。

       

      Abstract: The effects of different mulch methods on growth, yield, and quality of flue-cured tobacco were studied. The results showed that the “straw mulching after film uncovered” technique improved soil temperatures during the early field period, promoted tobacco plants to grow early and quickly and reduced the proportion of early budding plants. At the flue-cured tobacco maturing stage, it decreased soil temperatures, maintained soil moisture and root vigor, and lengthen mature time of top leaves. At the same time, it remarkably increased yield and value, increased reducing sugar contents and decreased nicotine contents of tobacco leaves.
