要:为探讨覆盖对丽江金沙江河谷地区烟田土壤温度、水分及烤烟生长和化学成分的影响,以云烟 87 为材料,于团棵
期后,进行揭膜及不同覆盖的比较试验。结果表明,覆盖能提高烟株农艺性状,促进烟株生长;能调节土壤温度,减小土壤
温差,使土壤含水量提高;覆盖使叶绿素相对含量提高,降低总糖、还原糖含量,提高总氮、烟碱、蛋白质含量。其中地膜
加秸秆覆盖可以降低膜内土壤温度,克服单一地膜覆盖温度过高而秸秆覆盖地温较低的弊端,有利于改善根区土壤环境,维
持和提高根系活力,提高烟叶品质。

Abstract: parative field experiment was carried out after rosette stage in Jinsha river valley in Lijiang to explore the effects of
mulching on soil temperature, moisture, and growth and position of flue-cured o. The results showed that
mulching improved agronomic characters and promoted growth of o; mulching could regulate soil temperature and reduce soil
temperature difference, improve soil moisture content; mulching improved relative chlorophyll content, reduced total sugar and
reducing sugar content
