据悉，PBST(聚对苯二甲酸丁二酸丁二醇酯)是中国石化所属北京化工研究院开发出具有完全自主知识 产权的全生物降解材料，用其制成的地膜在抗紫外线、水汽阻隔等方面表现较其他全生物降解材料更为 优异。多年试验表明，PBST地膜在不同地域、不同作物使用后，1至3年内可完全降解成水、二氧化碳 和矿化物等无害物质。 10月，第三方机构评估和实收测产数据显示，覆盖PBST地膜的棉田与对照组覆盖PE地膜的棉田相比产 量总体相当，地膜降解速度明显，未来可完全降解成水、二氧化碳和矿化物等无害物质，不需要回收。 在满足新疆棉花生长需要的同时，降低了成本，并有效解决了PE残留地膜对土壤的影响问题，经济和 生态效益明显，为新疆农业可持续发展提供了可复制推广的实施路径。(完) 中新社北京11月13日电 记者13日从中国石化获悉，中国石化在新疆维吾尔自治区乌苏市发布万亩棉田 PBST地膜试验示范项目成果，宣布其完全自主知识产权的PBST全生物降解地膜试用成功，与使用传统 PE(聚乙烯)地膜的对照田相比，棉花产量总体相当，为稳定棉花产量、解决地膜残留问题提供了可行路 径。 新疆作为中国重要的棉花产区，长期使用PE地膜以保墒增温，然而PE地膜 ...
