Abstract
The present application relates to the field of degradable new materials, in particular to a mulching paper using lignin and a production method thereof, specifically, lignin, a biomass material, is applied to the production of the mulching paper, wherein the paper is mainly made of unbleached conifer chemical pulp and unbleached broadleaf chemical pulp as paper fiber raw materials, and a coating mainly made of lignin is coated on the surface of the paper, the coating can simultaneously play the roles of sterilization and bacteriostasis, improving the disease resistance of crops, inhibiting weeds, improving the water resistance, improving the physical strength, solving the problem that traditional mulching films cannot be degraded, and achieving the use effect even better than that of ordinary mulching films.
