摘　　要：采用田间试验研究了地膜覆盖与烤烟根系及烟叶产量品质的关系。结果表明:烤烟移栽后不同时期盖膜处理根的长度、数量、干重明显大于不盖膜处理,80d时根的长度、数量、干重与盖膜时间呈极显著正相关。烟叶产量、产值与80d时的根长度呈显著正相关,与100d时的根数量呈显著正相关。60d时的根数量与下部烟叶还原糖含量呈显著负相关,与下部烟叶钾含量呈显著正相关。80、100d时的根长度、根数量与上部烟叶的还原糖含量呈显著正相关;100d时根干重与上部烟叶钾含量呈显著正相关。盖膜处理的评吸质量明显高于不盖膜处理,盖膜有利于改善烟叶品质。The correlation of film-cover and roots and yield, and quality of flue-cured tobacco was studied by field experiment. The results indicated that the length, quantity and dry weight of roots covered film at different staged was higher than those without film-cover. The length, quantity and dry weight of sample roots at 80d after transplanting was obviously positive correlative with film-cover time. The leaf yield and output value was positive correlating with the 80d-aged or 100d-aged roots length. The root quantity at 60d was obvious negative correlative with the content of reducing sugar of bottom leaf but was obvious positive correlative with the K content. The 80d-aged or 100d-aged root length was positive correlative with reducing sugar content of upper leaf, the 100d-aged root dry weight was positive correlative with the K content of upper leaf. The smoking quality of mulching treatment was higher than that of no mulching. Mulching film can improve the quality of tobacco leaf.
