| 摘 要： | 以云烟87为研究对象,于2018-2019年连续2年研究了烟草还苗期常规灌溉、轻度补灌和重度补灌3种灌溉方式与白膜、转光膜、配色膜和黑膜4种覆膜颜色互作对前期垄体膜下土温、土壤含水率,揭膜时烟株农艺性状、干物质积累量和烤后烟产质量的影响。结果表明：在不同补灌条件下,补灌方式对垄体膜下土温影响较小;在相同补灌条件下,白膜和转光膜升温效果优于配色膜和黑膜;垄体膜下0~15cm土壤含水率表现为黑膜>配色膜>转光膜>白膜,15~30cm土层土壤含水率表现为白膜>转光膜>配色膜>黑膜。在相同覆膜处理下,移栽后1~7d土壤含水率随补灌量的增加呈上升趋势,0~15cm土层上升较显著。互作处理M-Z（轻度补灌+转光膜）揭膜时烟株、根茎叶干物质积累量最高,烤后烟的产质量表现最好。在襄阳山区采用轻度补灌+转光膜方式可促进烟株大田生育期前期生长发育,提升烟叶产量和质量。

| Abstract: | In this study, Yunyan 87 was taken as study material. In 2018 and 2019, the interaction of three irrigation methods (conventional irrigation, mild supplementary irrigation and heavy supplementary irrigation) and four kinds of films (white film, light-transfer film, color matching film and black film) was studied on soil temperature and soil moisture content under ridging films at seedling stage, the agronomic characters and dry matter accumulation of tobacco plants when uncovering films, as well as the yield and quality of tobacco after roasting. The results showed that: the effect of supplementary irrigation methods on soil temperature under ridging films was small. The heating effect of white film and light-transfer film was better than that of color matching film and black film under the same supplementary irrigation condition, and the moisture content of 0-15cm soil under the color-coated ridging films was black film > color matching film > light-transfer film > white film, and the moisture content of 15-30cm soil was white film > light-transfer film > color matching film > black film. Under the same mulching treatment, the soil moisture content in the 1-7d after transplanting showed an increasing trend with the increasing of the supplemental irrigation amount, especially in the 0-15cm soil layer. The matter accumulation of roots, leaves and branches, as well as the yield and quality of flue cured tobacco were the best when the agronomic characters of tobacco plants were treated with M-Z (light supplementary irrigation + light film). Based on the comprehensive analysis, the technique of light supplementary irrigation + light film could promote the growth and development of tobacco plants in the early stage and improve the yield and quality of tobacco leaf. |
