Degradable mulching film and preparation method thereof

The invention belongs to the technical field of degradable materials, and particularly relates to a degradable mulching film and a preparation method thereof.The degradable mulching film is prepared from, by weight, 70-90 parts of plant starch and 10-30 parts of plant fiber, the plant fiber comprises straw and sugarcane peel fiber, and the weight ratio of the straw to the sugarcane peel is (3-5): 1. The degradable mulching film provided by the invention is formed by compounding the plant starch, the straw fibers and the sugarcane peel fibers, and the prepared degradable mulching film is high in tensile strength, good in toughness, easily available in raw materials, low in cost, simple in preparation method and easy to implement. 本发明属于可降解材料技术领域，特别涉及一种可降解地膜及其制备方法，其原料包括重量为70-90份的植物淀粉和10-30份的植物纤维，所述植物纤维包括秸秆和甘蔗皮纤维甘蔗皮，所述秸秆与甘蔗皮的重量比为3-5:1。本发明提供的可降解地膜，以植物淀粉、秸秆纤维和甘蔗皮纤维复合而成，制备的可降解地膜拉伸强度高，韧性好，原料易得，成本低，制备方法简单，易于实现。
