光降解地膜。主要采用在合成樹脂中加入光敏劑的方法使之降解。該技術(shù)由英國G．SC0tt和以色列D． Gilead**，并在英國、以色列和南非應(yīng)用。前蘇聯(lián)、日本也曾開展過此項(xiàng)研究。我國于20世紀(jì)80年代初開始研制光降解地膜，采用了與國外相近的工藝路線，目前已達(dá)到規(guī)模化生產(chǎn)的水平。但由于光降解地膜埋土部分不降解；降解后碎片不易繼續(xù)粉化或被土壤同化，污染土壤問題仍未得到根本解決。另外成本較普通膜高，使推廣應(yīng)用受到限制。 </p> <p> 生物降解地膜。能通過微生物作用降解的地膜（較低層次的生物降解地膜）。這種地膜主要以天然高分子為原料，如日本采用纖維素與甲殼素水溶液制膜，德國采用直鏈淀粉或高直鏈淀粉及其它天然高分子材料制膜，我國也曾采用纖維素來制膜。但是，盡管這些薄膜能夠降解，但都存在加工困難、力學(xué)性能和耐水性能差的問題，根本無法加以推廣和應(yīng)用。
