Degradable high-performance plant fiber comprehensive agricultural plastic mulching film and preparation method thereof

Abstract

The invention discloses a degradable high-performance plant fiber comprehensive agricultural plastic mulching film and a preparation method thereof. The agricultural plastic mulching film is prepared from the following raw materials: plant fibers, starch, cellulose, an enhancer, a waterproof agent and a filter aid. The texture of the agricultural plastic mulching film is between paper and cloth, so that the agricultural plastic mulching film is a novel degradable agricultural plastic mulching film; furthermore, after being degraded, the agricultural plastic mulching film can become fertilizer for nourishing soil; in addition, the degradation time of the agricultural plastic mulching film can be controlled by controlling the consumption of the starch and the waterproof agent in the raw materials. The degradable high-performance plant fiber comprehensive agricultural plastic mulching film does not need to be recovered after autumn, so that the manpower is saved, and the environment is protected.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a degradable high-performance plant fiber comprehensive agricultural mulch film and a preparation method thereof. Background technique [0002] With the rapid development of the plastic industry, in agriculture, due to the use of agricultural mulch, the temperature and humidity of the soil are effectively controlled, the loss of water and nutrients is reduced, and the high yield and stability of crops are promoted, thereby increasing agricultural production. benefits. [0003] Agricultural plastic mulch began to be used in the middle of the 20th century. It was first applied to strawberry production in Japan in 1955 and promoted. In the early 1960s, France, Italy, the United States and other countries began to apply agricultural plastic mulch to the production of vegetables, fruits, coffee, tobacco, cotton and other crops, and all achieved good results. Since our country intr...

Problems solved by technology

Paper mulch can be completely degraded by soil microorganisms without pollution, but the paper mulch has poor wind and rain resistance and is easily damaged. The tearing strength is greatly reduced after rain, and it is not easy to mechanize the film. At the same time, the price is relatively expensive, and it is currently used in production. less

At the end of the 20th century, Japan developed agricultural hemp mulch, which mainly uses pulp and hemp fiber as raw materials. Compared with paper mulch, its toughness is greatly enhanced and the efficiency of mechanized laying is improved. However, Japanese hemp fiber is scarce and expensive, making it difficult to popularize and apply it in large quantities.
