Preparation and Performance of Gelatin/Chitosan/Hydroxypropylmethylcellulose Biodegradable Mulch Film
In order to effectively solve the soil pollution problem caused by non degradable membranes in petrochemical bases and promote the sustainable development of the agricultural industry, this study designed a three factor three-level experiment based on single factor experiments, using gelatin/chitosan as the substrate, hydroxypropyl methylcellulose (HPMC) as the reinforcing phase, and glycerol as the plasticizer. Design Expert software was used to design an experiment with gelatin/chitosan mass fraction, gelatin/chitosan ratio, and HPMC mass fraction as independent variables and soil moisture loss of plastic film as the response value. The results show that the water retention performance of biodegradable mulch film is optimal when the gelatin/chitosan ratio is 6∶1, the gelatin/chitosan mass fraction is 7.3%, and the HPMC mass fraction is 2.1%. The tensile strength of the biodegradable film is 34.3 MPa, the light transmission rate is 35.8%, and the degradation rate is 92.7% in 35 days. The new biodegradable mulch prepared provides a basis for the possible application of soil pollution control and other aspects.
