摘　　要：在大田条件下,对生物降解膜与普通地膜进行对比试验。结果表明:与普通地膜相比,生物降解膜在覆膜后20 d开始降解,45 d后出现降解加速,在60 d后降解速度缓慢,而普通地膜无降解变化;与普通地膜相比,生物降解膜不利于烤烟的生长发育,烤烟的经济性状低于普通地膜。This test was done in order to analyze the difference between biodegradable film and ordinary film under field conditlon.The results showed that compared with ordinary film, biodegradable film was degraded after 20 days, accelerated degradation after 45 days, slowly degraded after 60 days, but ordinav film was not degraded at all ;the biodegradable film went against tobacco growth,its economic characters were lower than ordinav film.
