由安徽省农学院研制的可降解塑料薄膜,经光——生物降解对比试验表明,居世界领先水平。这种光降解银色塑料薄膜,降解速度快,使用后2个月内98％以上的畦面土壤裸露,降解彻底性好,无明显残留碎片,即使残留极少量碎片,也成糟化或卷成0.1×—1.5厘米的针筒状,并继续分解为粉末。该银光膜有良好的反光性能,其反射顶峰始终稳定在近紫外光区,因此,很适合农作物对光、温、水、气的要求。同时,该薄物料无毒,可明显改善土壤理化性状。
The biodegradable plastic film developed by Anhui Agricultural College shows that it has the highest level in the world due to comparative experiments with light-biodegradation. The photodegradation of silver plastic film, the degradation rate, within 2 months after use 98% of the clay surface exposed, thorough degradation of good, no significant residual debris, even if a very small amount of debris left, but also worse into or worsened 0.1 × -1.5 cm syringe shape, and continue to decompose into powder. The silver film has a good reflective properties, the reflective peak is always stable in the near ultraviolet region, so it is suitable for crop light, temperature, water, gas requirements. At the same time, the thin material is non-toxic, can significantly improve soil physical and chemical properties.
