摘要
在玉米上进行了生物降解树脂农膜和普通地膜应用对比研究。结果表明,生物降解树脂农膜和普通地膜在对玉米生长发育的影响,提高土壤水分含量和土壤温度以及玉米产量方面无明显差异,说明生物降解树脂农膜可以替代普通地膜在生产上应用。此外,生物降解树脂农膜在作物生长后期开始降解,降解膜先裂缝,后变成小碎片,最终变成末状,不会产生残膜对土壤环境的污染问题。
A Contrastive experiment for the effect on the maize between decomposing biological resin film and common ground film has been conducted .The results showed that there was no obvious difference between the effect of decomposing biological resin film and common ground film on the maize development and yield,and the increase of soil moisture and temperature.So the decomposing biological resin film can replace the common film in the production.In addition,the decomposin biological resin film became to decompose during later stage of the crop growing .At first, it cracked, then became little fragments,finally turned into powder. Therefore,there is no pollution problems of remnant film to soil environment.
