摘　　要：为了综合评价丽江烟区地膜覆盖对烤烟生产的作用,采用灰色关联分析法研究了不覆盖地膜、移栽后20 d揭膜培土、移栽后35 d揭膜培土、移栽后50 d揭膜培土、全生育期盖膜共5个不同揭膜时间的处理对烟叶产量、均价、上等烟比例、总糖含量、烟碱含量、K_2O含量、香气量、香气质、杂气、刺激性的综合影响。结果表明,移栽后35 d揭膜为最优处理,其烟叶产值量最优,烟叶内在化学成分协调,评吸得分高,品质好,其产量、均价、上等烟比例、总糖、烟碱、K_20、香气量、香气质、杂气、刺激性分别为167.25 kg/666.7m^2,12.13元/kg,56.4%,38.36%,2.52%,2.13%,6,6,5.5,5.5。分析结果与生产实际表现一致。Aim to evaluate effect of plastic film on the flue-cured tobacco in Lijiang, a field experiment were carried out that effects of different durations of disclosing plastic film with 5 treatments on tobacco leaf production, average price, the proportion of quality tobacco, th5 total sugar content, nicotine con- tent, K20 content, aroma, fragrant qualities, mixed gas and irritating were studied by the way of using gray relational analysis, which included No Film, 20 days after transplanting removing film, 35 days after transplanting removing film, 50 days after transplanting removing film, whole field duration film. The results showed that 35 days after transplanting removing film was the best process which had a optimal tobacco leaf; more coordination in chemical quality; high score in smoking assessment and good quality. Its yield, average price, high grades proportion, total sugar, nicotine, Kz O, volume of aroma, quality of aroma, offensive odor, irritation respectively fellow as 167.25 kg/666.7m^2, 12. 13 Yuan/kg, 56.4%, 38.36%, 2.52%, 2.13%, 6, 6, 5.5, 5.5. The analysis was consistent with the actual production.
