摘要
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 anti＇ 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 tbe growth and development of tobacco plants after vigorous growth stage, and raise the yield, output value and superior - level propor tion of tobacco leaves.
