双降解地膜是一种含有生物降解和适量光氧降解成分的绿色农用地膜产品,它在使用时与普通地膜有相同的功效,而在使用后期或在农田裸露堆置3~6个月后,在光和土壤微生物的共同作用下,可自行降解碎裂,直至完全消失。消除了普通地膜给农田带来的“白色污染”,是一项既能代替普通地膜,又能保护农业生态环境的新型覆盖材料。1.双降解地膜的特点(1)双降解地膜和普通地膜一样,铺设后具有提高地温、保持土壤水分、增加作物产量的作用。(2)双降解地膜在起始物
Biodegradable film is a biodegradable and appropriate amount of photo-oxygen degradation components of green agricultural film products, which use the same time with the normal film has the same effect, and in the late use or farmland exposed after 3 to 6 months, Under the action of light and soil microorganisms, the fragmentation can be degraded by itself until completely disappeared. Elimination of “white pollution” caused by ordinary plastic film to farmland is a new type of covering material that can replace common plastic film and protect agricultural ecological environment. 1. Double degradation of the characteristics of the film (1) Double Degradation Film and ordinary film, after laying with the increase of ground temperature to maintain soil moisture and increase crop yield. (2) double degradation of the film in the starting material
