1、安徽农业科学,JournalofAnhuiAgn.Sci.2015,43(1):53—55责任编辑乔利利责任校对李岩可降解地膜、液体地膜在烤烟上的应用研究崔德强,杨春江。(1.湖南农业大学烟草研究院,湖南长沙410128;2.云南省烟草公司普洱市公司,云南普洱665000;3.云南省烟草农业科学研究院,云南昆明650021)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
2、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,各处理问差异不显著;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。关键词烤烟:可降解地膜;液体地膜;品质中图分类号S365
