摘要
采用田间试验研究了不同揭膜培土技术对云烟87的生长发育、经济性状、物理指标及化学成分的影响。结果表明:与不覆膜的烤烟相比,经过揭膜处理的烤烟在叶片面积、有效叶片数、株高、茎围方面有一定的优势;产量和产值均有不同程度的提高;初烤后叶片的叶长、叶宽及单叶重均有所增加;且在化学品质方面更为协调。总体而言,移栽后地膜覆盖至旺长期揭膜可以显著提高云烟87的品质。
Effects of different film uncovering technologies on growth,economic properties,physical properties and internal chemical properties of Yunyan 87 were studied through field experiments.The results showed that in contrast to the non-covered flue-cured tobacco,the flue-cured tobacco with film uncovering treatment had some advantages in leaf area,effective leaves,plant height and stem girth;yields and production value all increased in different degrees;leaf length,leaf width and single leaf weight of roasted leaves all increased;more coordination in chemical quality.Overall,film covering after transplant and film uncovering at strong growth period will significantly improve the quality of Yunyan 87.
