摘　　要：[目的]综合评价可降解地膜、液体地膜对烤烟抗旱和生长的影响。[方法]通过田间试验研究了可降解地膜、液体地膜对烤烟生育期、田间农艺性状及经济性状的影响。[结果]常规地膜处理比其他处理对烟株的早生快发要早,而各处理又好于不盖膜处理,可降解地膜又好于液体地膜。法国产可降解地膜的降解率大于常规地膜。单叶重以覆禾美特液体地膜处理最重而覆盖法国产可降解地膜的处理最轻,各处理间差异不显著;上等烟比例和产值以覆盖法国产可降解地膜的处理最高,而常规移栽、不覆膜的处理最差,各处理间差异不显著;中等烟比例以常规移栽、不覆膜的处理最高而覆盖常规地膜的处理最低;产量以覆金旺液体地膜的处理最低而覆盖法国产可降解地膜的处理最高。[结论]从环境、经济等情况来看,可挑选合适的可降解地膜进行推广,降低劳动强度,改进烤烟生产技术。[Objective] The aim was to evaluate effects of degradable plastic film and liquid film on drought resistance and growth of flue- cured tobacco. [ Method ] Effects of degradable plastic film and liquid film on growth period, agronomic characters and economic characters of flue-cured tobacco were studied through field experiment. [ Result ] The growth period of conventional film treatment was better than that of other treatments ; the growth period of film treatment was better than that of no-film treatments ; the growth periods of degradable plastic film treatment was better than that of liquid film treatment. The degradation rate of French degradable plastic film treatment was more than that of conventional film treatment. As for the weight per leaf, Hemeite liquid film showed the best, while French degradable plastic film showed the worst, and there was no difference among all treatments. As for fine tobacco ratio and output value, French degradable plastic film showed the highest, while no plastic film showed the worst, and there was no difference among all treatments. As for medium tobaccolratio, the no plastic film showed the highest, while the conventional film showed the worst. As for yield, Jinwang liquid film showed the lowest, while French degradable plastic film showed the highest. [ Conclusion ] According to environment and economy, degradable plastic film could be popularized to reduce labor intensity g and improve production technology.
