摘　　要：采用无毒的植物残渣为主要原料合成了一种新型复合体系液体地膜.对其光老化性能、最大稀释倍数及试验田土壤中水分分布等多项性能的测试结果表明:该新型液体地膜具有良好的长期和低温储存稳定性;老化时间为50 d,完全可以满足作物生长周期的要求;最大稀释倍数在保证抑蒸率满足使用要求的情况下由普通沥青体系液体地膜的7倍~8倍提高至20倍;覆盖的土壤在0 cm^40 cm的水分分布比较均匀,且土壤的表面温度比用塑料地膜高2℃~3℃.A new compound system of liquid mulching film was composited using phyton residue. Which of the light standard of judging ages and the determination of maximal extension rate and the influence on moisture content in study plot were studied. It proves that it has long term and good stability when stored in a low temperature. Ageing time is 50 d, which meets the demand of crops growth. Under the condition of suppressing to steam the rate ,the maximal extension rate increases from common 7 times or 8 times to 20 times, The moisture content is more homogeneous when covering liquid mulching film in 0 cm to 40 cm, and temperature is higher 2 ℃ to 3 ℃ than in plastics mulching film on the surface of the soil.
