摘要
以普通聚乙烯地膜为对照,研究了以玉米淀粉为主要原料制备的生物降解保水地膜的田艺特性。结果表明:生物降解地膜同普通聚乙烯地膜一样,具有保温、保水的作用,但在土壤性状及促进作物生长方面均优于普通地膜,且具有全生物降解特性。该研究结果为淀粉基全生物降解地膜的推广和应用提供了理论依据和实际参考。
The field characteristics of biodegradable farm film made from corn starch as main material were studied in contrast with PE farm film. Results show that the biodegradable farm film has the same thermal holding and moisture holding characteristics as the PE farm film, additionally the biodegradable farm film is superior in improving soil characters and accelerating crop growth, and it is completely biodegradable. The conclusion in the work provides theoretical base and practical references for popularizing and applying biodegradable farm film.
