塑料薄膜地面覆盖栽培,已在我国许多作物上大面积推广。实践证明残膜不能自然分解,常此应用将会造成农田环境污染的严重后果。为此,中国科学院长春应化所研制了“可控光解塑料地膜”,1983—1985年组织了中试生产和农田应用研究。我所参加了应用研究协作,现将研究结果整理如下,供参考。 Plastic film ground cover cultivation, has many crops in our country a large area to promote. Practice has proved that the residual film can not be naturally decomposed, often this application will cause serious consequences of farmland environmental pollution. To this end, Changchun Institute of Chemical Technology, China has developed a “controlled photolytic plastic film”, 1983-1985 organized pilot production and farmland applications. I participated in the application of research collaboration, the findings are summarized below, for reference.
