Abstract

The invention provides a mulching film prepared by utilizing rice straw and a preparation method thereof and relates to the field of crop straw utilization. The mulching film comprises, by weight, 60-80% of rice straw fiber, 10-30% of waste silk fiber, 1-3% of biological organic fertilizer, 3-10% of polyvinyl alcohol, 1-5% of corn starch, 1-3% of glycerin, 1-3% of sorbitol fatty acid ester and 0.1-0.5% of mineral. The preparation method includes following steps: preparing the rice straw fiber; treating the waste silk fiber; performing nonwoven networking; bonding and curing. The mulching filmhas high strength and air permeability and is degradable, a lot of cellulose after degradation can play a role in improving soil, and utilization value is increased.

Description

technical field [0001] The invention relates to the field of crop stalk utilization, in particular to a mulch film prepared by using rice stalks and a preparation method thereof. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining parts of wheat, rice, corn, potatoes, oilseeds, cotton, sugar cane and other crops after harvesting seeds. It is a multi-purpose renewable biological resource. People's most direct impression of straw treatment is that it is burned in large quantities in the field. It suffocates people, airports are out of service and highways are closed due to straw burning, and the losses are incalculable [0003] my country is a major rice producing country, and a large amount of rice straw is produced every year. Most of the rice straw is discarded and burned at will, causing great environmental pollution, affecting the quality of life of farmers, and causing a great waste of...
