以制浆废液中的工业级禾本科木质素为原料，经羟甲基化后与尿素或木质素芳环进行交联反应制备液体地膜。结果表明，木质素的加入量对液膜材料的性能、粘度和耐水性有影响。当木质素用量小于30%时，这种影响较小，当木质素用量大于30%时，这种影响变得明显。木质素的最佳添加量为30%。当液膜材料浓度在1000 mg/L左右时，对植株生长有促进作用。地膜和液体膜都能提高土壤温度，液体膜的效果略差于地膜，但优于对照。木质素的最佳添加量为30%，此时热培养效果最好。
Liquid mulching film was prepared with technical gramineae lignin from waste pulping liquid via hydroxymethylation and then cross-linking reaction with urea or aromatic ring of lignin. Results showed the amount of lignin added had an influence on the property, viscosity and water resistance of liquid film material. This influence was little when lignin dosage was less than 30%, but turned apparent when lignin dosage was higher than 30%. The optimum lignin quantity was 30%. The growth of plant was accelerated when the concentration of liquid film material was around 1000 mg/L. Both planstic and liquid mulching film could improve soil temperature, the result of liquid film was a little worse than that of plastic film, but was better than the control. The optimum lignin dosage was 30% which had the best heat incubation effect.
