Abstract

The invention relates to a biogas residue fiber mulch film and a manufacturing method thereof, which belong to the technologies of protective cultivation biomass materials of paddy and upland crops. The fiber mulch film consists of biogas residue fibers, plant fibers and an environment-friendly functional auxiliary agent, wherein the biogas residue fibers account for 50-90%, the plant fibers account for 10-50%, and the sum of the two types of the fibers is 100% by weight of dry matters; and the environment-friendly functional auxiliary agent mainly comprises rosin, bauxite and a wet strengthening agent and accounts for 6%-7.4% of 100% of the total weight of the two types of the fiber dry matters. The manufacturing technology adopts the biological and mechanical way for preparing the fibersand pulp and adds the environment-friendly functional auxiliary agent for manufacturing paper and forming the film. The biogas residue fiber mulch film has excellent performance for inhibiting the breeding of weeds and can simultaneously adjust the ground temperature, preserve the soil moisture, increase the humidity, improve the ecological environment of the crops, can be completely biodegradedduring the growth period of the crops, improve the content of organic matters in the soil, have no residue or pollution and realize good economy.

Description

Technical field:

[0001] The invention belongs to the protection cultivation biomass material technology of paddy and dry crops in the organic agricultural production system, and mainly relates to a biogas residue fiber mulch film and a manufacturing method thereof. Background technique:

[0002] Since the 1960s, plastic mulch has been widely used in farmland for increasing production and income. However, plastic mulch is difficult to recycle and cannot be degraded naturally, causing serious "white pollution". The disposal of residual film has become a worldwide problem, so research on biodegradable mulch is imminent.

[0003] The research and development of degradable plastic film at home and abroad is very active. From the middle of the 1990s to the beginning of this century, Japan carried out systematic research on the manufacture of paper mulches mainly by blending secondary fibers such as waste packaging and some original pulp fibers with polymer resins; South Korea als...
