Comparison of Traditional and Biodegradable Agricultural Mulch Film Used in China (Chinese Version) 中国传统地膜与全生物降解地膜的比较研究

尽管聚乙烯地膜的使用为农业生产与农产品安全供给做出了巨大贡献,但是长期应用也带来地膜残留问题,使得土壤结构破坏、作物生长发育受阻、影响农事操作等。面对新的问题,也出现一些新的机遇,如使用环境友好型的全生物降解地膜作为新产品进行替代。但传统聚乙烯地膜与全生物降解地膜的功能性、经济性、生态环境效应之间的研究需要进一步加强,明确二者的差异性、互补性与应用前景。因此,本报告旨在系统的阐述传统地膜与全生物降解地膜各自的特点,并从上述的三个维度对两种产品进行全面的比较,发现、权衡各自的优劣势,进而选择适合中国的地膜污染防治措施。
