降解地膜是為適應(yīng)社會對于環(huán)境保護(hù)的需要而產(chǎn)生的一種新型地膜，主要原料為降解母粒與塑料粒子母料混合生產(chǎn)而成。降解是利用自然界中的微生物對地膜侵蝕或者是利用太陽光氧化的作用而達(dá)到的降解。 </p> <p> 由于農(nóng)用地膜的使用，有效的控制了土壤的溫度和濕度，減少了水分和營養(yǎng)物的流失，促進(jìn)了農(nóng)作物的高產(chǎn)和穩(wěn)產(chǎn)，從而增加了農(nóng)業(yè)生產(chǎn)效益。但與此同時(shí)，由于地膜的一次性使用，每年都會有大量的殘膜留在土壤里。塑料地膜在自然界中很難降解。這些地膜碎片可在土壤中形成阻隔層，使土壤中的水、氣、肥等流動(dòng)受阻，造成土壤結(jié)構(gòu)板結(jié)，嚴(yán)重危害生態(tài)環(huán)境，造成白色污染。因此, 解決殘膜污染土壤問題已成為地膜覆蓋栽培技術(shù)的當(dāng)務(wù)之急, 為了解決這一問題, 可降解地膜的研究應(yīng)運(yùn)而生。 </p> <p> 隨著人類社會對環(huán)境問題認(rèn)識水平的不斷深化，解決廢棄地膜造成的"白色污染"建立環(huán)境友好性社會，建立人與環(huán)境的良性互動(dòng)，***的辦法就是推廣應(yīng)用可降解地膜。而其中光--生物雙降解地膜的發(fā)展及推廣尤為重要。雙降解地膜的研究，是今后我國地膜產(chǎn)業(yè)的發(fā)展趨勢，也是發(fā)展可持續(xù)性農(nóng)業(yè)的必要前提。
