新疆維吾爾自治區(qū)質(zhì)量技術(shù)監(jiān)督局副局長(zhǎng)夏青指出，新修訂的《聚乙烯吹塑農(nóng)用地面覆蓋薄膜》將此前地膜推薦性地方標(biāo)準(zhǔn)修改為強(qiáng)制性標(biāo)準(zhǔn)。在地膜厚度標(biāo)準(zhǔn)上，取消了國(guó)家標(biāo)準(zhǔn)的0.008毫米最小厚度，保持0.01毫米最小厚度，并增加了0.012、0.014、0.2毫米三個(gè)厚度，同時(shí)提供了推薦使用天數(shù)。
此外，本次地方標(biāo)準(zhǔn)修訂以“可回收”為目標(biāo)，充分考慮當(dāng)?shù)貧夂蛱攸c(diǎn)和農(nóng)業(yè)生產(chǎn)方式，所確定的農(nóng)膜厚度指標(biāo)和物理機(jī)械性能指標(biāo)更適合地膜使用和回收。
據(jù)了解，20世紀(jì)80年代，新疆首先在棉花種植上大范圍推廣地膜覆蓋技術(shù)。新疆目前成為國(guó)內(nèi)地膜覆蓋種植面積最大、地膜用量最多、普及率最高的地區(qū)。據(jù)調(diào)查統(tǒng)計(jì)，當(dāng)?shù)剞r(nóng)田平均每畝地膜殘留量已達(dá)16.88千克，是全國(guó)平均水平的4~5倍。
