用聚乙烯塑料薄膜(地膜)栽培农作物,是70年代末我国从日本引进的一项新技术。这项被称为“白色革命”的新技术。对我国农业生产的发展起到了积极的推动作用。但是,随着地膜长期大量使用,它所带来的“白色污染”已开始引起人们的关注。地膜使用后残留在田间地角,不腐烂,不分解,使土壤的通气性和透水性变差,逐渐板结,影响了农事操作和作物的正常生长,从而导致减产。我国科技人员在12个县市试验结果表
With polyethylene plastic film (film) cultivation of crops, is the late 70s China imported from Japan a new technology. This is known as the “white revolution” of new technologies. The development of China’s agricultural production has played a positive role in promoting. However, with the long-term use of mulch, its “white pollution” has started to attract people’s attention. After the use of the film remains in the field angle, does not decompose, does not decompose, so that the soil permeability and permeability deterioration, and gradually consolidated, affecting the normal operation of agricultural operations and crops, resulting in reduced production.
