摘　　要：以废弃文冠果壳为原料制备液体地膜并考察其保水及保温性能。结果表明:液体地膜的—OH和—COOH基团可被土壤微生物所降解,埋入土壤12 d后,液体地膜表面呈现出的孔洞和收缩现象,距土壤表面8 cm处温度升高3.5℃左右。通过含水率对比试验时发现,液体地膜的覆盖可显著提高土壤的含水率。液体地膜的表面接触角为47.6°,抗拉强度为16.69 MPa,黏度为35.6 mPa·s,12 d后降解率达3.7%。Liquid film was prepared from waste Xanthoceras sorbifolia shell and its water retention and thermal insulation properties were investigated.The results showed that the-OH and-COOH groups of the liquid film could be degraded by soil microorganisms.After 12 days of embedding in the soil,the surface of the liquid film showed holes and shrinkage,and the temperature at 8 cm from the soil surface increased by about 3.5℃.Through the comparison experiment of water content,it was found that the coverage of liquid film could significantly increase the water content of soil.The surface contact angle of the liquid film was 47.6°,the tensile strength was 16.69 MPa,the viscosity was 35.6 mPa·s,and the degradation rate was 3.7%after 12 days.
