我国从1978年开始推广地膜覆盖技术至今,每年地膜用量达125万t,覆盖3亿亩40多种农作物。但目前废旧地膜的回收率不足30%,残留在土壤耕层里的地膜越积越多,形成了严重的“白色污染”。为此,山东一家企业成功研究出了氧化生物双降解生态地膜,不仅解决了多年困扰我国农业生产中难题,也使我国成为世界上第三个掌握此技术的国家。氧化生物双降解生态地膜综合利用了氧化降解和生物降解技术,可以根据不同作物的生育期需求,通过添加不同剂量
Since 1978, China began to promote plastic film mulching technology so far, the annual amount of plastic film reached 1.25 million tons, covering more than 40 million kinds of crops of 300 million mu. However, at present, the recovery rate of waste plastic film is less than 30%. The residual plastic film accumulated in soil piles increases and forms a serious “white pollution”. To this end, a Shandong enterprise successfully developed a biodegradable biodegradable oxide film, not only solved the problems that have troubled China’s agricultural production for many years, but also made our country the third country in the world to master this technology. Oxidative biodegradation Eco-membrane comprehensive utilization of the oxidative degradation and biodegradation technology, according to different crop growth period needs, by adding different doses
