通过大田小区试验，研究了烟垄不同覆盖方式对烟田环境、烟株生长发育及产质量的影响。结果表明：前期地膜覆盖、揭膜培土后进行稻草覆盖处理能够维持较高的根系土壤含水量，提高中部叶的净光合速率，有利于烟株旺长期后的生长发育，能够提高烟叶的产量、产值及上等烟比例。

The effects of different mulching patterns on the environment of tobacco field , the growth and development of tobacco plants, and the yield and quality of flue -cured tobacco were studied through plot experiment in the field .The results showed that the treatment of mulching at earlier growth stage , and then removing the film and ridging the soil , finally covering with rice straw could effectively enhance the soil moisture around the root system , increase the net photosynthetic rate of middle leaves , promote the growth and development of tobacco plants after vigorous growth stage , and raise the yield , output value and superior -level propor-tion of tobacco leaves .
