【 摘 要 】

In order to eliminate the white pollution caused by film mulching and reduce the consumption of non renewable resources, scientists both at home and abroad are studying the completely degradable plant fiber film. In this study, a kind of environment-friendly degradable paper mulching film of cotton stalk fiber was prepared by mixing cotton stalk fiber and a part of waste cotton fiber as raw materials. The tensile strength index of cotton stalk fiber paper mulching film is 29.43N•m2•g-1, tearing index is 77.26mN•m2•g-1, and the wet strength is 32%. After 75 days of soil landfill, the degradability of the test was 64%, and the degradation in the soil was dispersed into small pieces. Through experimental study, the paper mulching film of cotton stalk fiber prepared is a completely biodegradable environment-friendly paper mulching film.
