随着塑料地膜大面积的生产应用,大量地膜残块遗留在土壤中,恶化土壤的理化性质,使后茬作物根系不能正常生长,同时给耕作带来不便:时间越长,残留的地膜残块越多,对作物生育影响越明显。为此新疆塑料厂研制了最新地膜产品——可控光降解膜。这种膜在一定时间的阳光照射后,自然分解成小碎片,大大减少了普通地膜对后茬作物的危害。本试验是验证该种可控光降解膜的降解效应以及是否具有普通地膜栽培的优点。
With the large-scale plastic film production and application, a large number of residual membrane residue left in the soil, deterioration of the physical and chemical properties of the soil, so that the stubble crop roots can not grow normally, while bringing inconvenience to farming: the longer the residual membrane residue The more, the more obvious the impact on crop growth. To this end, Xinjiang Plastic Factory developed the latest film products - controlled photodegradable film. This film in a certain period of time after the sunlight, the natural decomposition into small pieces, greatly reducing the common film on the crop after the endangered. This test is to verify the degradation effect of the controlled photodegradable film and whether it has the advantages of ordinary film cultivation.
