</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，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、肥等流動受阻，造成土壤結構板結，嚴重危害生態(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的當務之急, 為了解決這一問題, 可降解地膜的研究應運而生。 </p> <p> 隨著人類社會對環(huán)境問題認識水平的不斷深化，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，***的辦法就是推廣應用可降解地膜。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。深圳透明降解膜價格</p><p
