摘　　要：为探索适合连州烟区烤烟生产的最佳透光率地膜,采用不同透光率地膜为材料,研究了地膜对烤烟生长发育及产量的影响。结果表明:透光率为50%的纯黑色地膜能缩短烤烟大田生育期,增加烟株的株高、茎围、有效叶片数和最大叶面积,增强烟株抗病性,能在一定程度上提高烟叶的产量、均价和上等烟比例。In order to explore the best mulch film with light transmittance for the production of flue-cured tobacco in Lianzhou tobacco area,the effect of mulch film with different light transmittance on the growth and yield of flue-cured tobacco was studied.The results showed that the pure black mulch film with 50%light transmittance could shorten the field growth period of flue-cured tobacco,increase the plant height,stem circumference,the number of effective leaves and the largest leaf area,improve the disease resistance of tobacco,and to some extent,improve the yield,average price and the proportion of superior tobacco.
