最近,国务院副总理邹家华就降解膜问题批转有关负责同志。中国工程院副院长卢良恕会同中国农科院蔬菜花卉所朱德蔚所长组织有关专家研究提出了我国降解膜的研究开发现状及发展前景。 地膜覆盖技术1978年从日本引入我国,近年年覆盖面积已达到1.7亿亩,经济与社会效益巨大。但是废旧地膜田间残留污染问题困扰着这项技术的应用。目前解决的办法,一是生产高强度、耐老化、易回收的地膜,进行清除回收;二是研究开发降解地膜,这种膜覆盖完成后可自行崩坏降解成小块或粉末于
Recently, Vice Premier Zou Jiahua of the State Council approved the responsible comrades for film degradation. Lu Liang-shu, vice president of the Chinese Academy of Engineering, together with the director of the Institute of Vegetables and Flowers of the Chinese Academy of Agricultural Sciences, organized a study on the status of research and development and development of degradable membranes in China. Film-mulching technology was introduced into Japan from Japan in 1978, covering an area of 170 million mu in recent years. The economic and social benefits are huge. However, the problem of residual contamination of waste film field plagued the application of this technology. At present, the solution is to produce a high-strength, anti-aging and easy-to-recycle film for recycling; secondly, to research and develop a degradable film that can be degraded into small pieces or powder on its own after it is covered
