测定使用一段时间后的黄麻土工布相对重量及其纤维素、木质素、果胶含量的变化。结果表明 ,各试验小区土工布均有不同程度降解。在覆盖土工布加裸露方式处理试验小区 ,土工布纤维素降低 8.80 %、木质素降低 3.48%、果胶降低 2 .2 1 % ;在覆盖土工布加种龙须草方式处理试验小区 ,土工布纤维素降低 4.2 2 %、木质素降低 1 .52 %、果胶降低 0 .39%。 6个试验小区土壤全 N,P,K含量分析结果表明 ,覆盖土工布试验小区与不覆盖土工布试验小区相比 ,土壤 N,P,K含量富集明显 ,土壤肥力增强。 The relative weight of jute geotextiles and their changes of cellulose, lignin and pectin content after using for a period of time were measured. The results show that the geotextiles in all experimental plots have different degrees of degradation. Geotextiles in the coverage of the bare way to deal with the test plot, geotextile cellulose reduced 8.80%, lignin decreased 3.48%, pectin reduced 2.21%; in the coverage of geotextile plus Eragon ways to deal with the test plot, geotextile 4.2 2% cellulose, 1 .52% lignin, pectin decreased 0.39%. The results of soil N, P and K contents in 6 plots showed that soil N, P and K concentrations were significantly enriched and the soil fertility was enhanced compared with the test plots covered with geotextile.
