Degradable mulching film material for potato planting as well as preparation method and application of degradable mulching film material

The invention relates to a degradable mulching film material for potato planting as well as a preparation method and application of the degradable mulching film material. The material is prepared fromthe following raw materials: polybutylene terephthalate, polylactic acid, polymethyl ethylene carbonate ester, a compatilizer, inorganic filler, an antioxidant, an ultraviolet absorbent and a functional additive. Compared with traditional polyethylene mulching film, the degradable mulching film material for potato planting provided by the invention increases the yield per mu and the big potato rate remarkably after applied to potato planting, thereby having a good application prospect. 本发明涉及马铃薯种植用可降解地膜材料及其制备方法和应用，所述材料包括如下原料：聚对苯甲酸己二酸丁二醇酯，聚乳酸，聚甲基乙撑碳酸酯，相容剂，无机填料，抗氧剂，紫外线吸收剂和功能助剂。本发明的马铃薯种植用可降解地膜材料，与传统聚乙烯地膜相比，应用于马铃薯种植后，亩产量和大薯率明显增加，具有良好的应用前景。
