中国农科院土肥所有关专家认为:降解地膜,目前无论在工艺上、农艺上都存在着不少问题。目前对国内外近70～80种产品的测试表明,至今尚无一种能达到要求,因此,无法大面积推广。可是,现在有一些研制人员或企业,却未对此重视,在介绍自己产品时,只讲能降解,而不讲降解地膜的关键技术是否已经解决,致使一些单位盲目投资建厂。 Chinese Academy of Agricultural Sciences Soil and Fertilizer experts believe that all: degradation of plastic film, both in the current process, there are many problems in agronomy. At present, nearly 70 to 80 kinds of products at home and abroad have been tested and found that no one has yet reached the required standard so that they can not be widely promoted. However, there are some researchers or enterprises that have not paid much attention to this. When introducing their own products, they only talked about whether they could be degraded without referring to the key technologies for degrading the plastic film. As a result, some units blindly invest and build factories.
