| 为探索葛渣资源化利用新途径，通过室内蚯蚓养殖试验，研究了新鲜葛渣、腐熟葛渣及鲜葛渣与牛粪不同配比对赤子爱胜蚓（Eisenia fetida）生长繁殖的影响，以及蚯蚓堆制处理前后物料肥力属性的变化，并利用种子发芽实验判断蚯蚓堆肥效果。结果表明，纯鲜葛渣和纯腐熟葛渣不利于蚯蚓生长和繁殖。蚯蚓在鲜葛渣和牛粪的复混物料中可以正常生长繁殖，10% 鲜葛渣复混90% 牛粪的物料更有利于蚯蚓繁殖。不同物料经蚯蚓堆肥处理后，总有机质含量显著降低，总养分含量显著升高，种子发芽指数有一定程度的升高，70% 鲜葛渣复混30% 牛粪经蚯蚓堆肥处理后的总养分含量为102.2 g·kg-1，比10% 鲜葛渣复混90% 牛粪高出57.7%。研究表明，蚯蚓生物处理技术可应用于葛渣肥料化利用中，采用70% 鲜葛渣复混30% 牛粪进行蚯蚓堆肥，资源化利用效果最佳。 |

| In order to explore a new mode of resource utilization of Pueraria root residue, a pilot vermicomposting indoor experiment was carried out using Eisenia fetida for bio-transformation of freshly decomposed Pueraria root residue and fresh Pueraria root residue mixed with cow dung at different ratios. The effect of decomposed Pueraria root residue and the effects of different ratios of Pueraria root residue and cow dung on the growth and reproduction index of earthworm were analyzed. The changes in fertilizing properties of the materials were analyzed before and after vermicomposting, and seed germination was evaluated to determine the effect of vermicomposting. The results showed that fresh Pueraria root residue and decomposed Pueraria root residue alone were not conducive to the growth and reproduction of earthworms. Earthworms were able to grow and reproduce normally in fresh Pueraria root residue mixed with cow dung, which a mixture of 10% fresh Pueraria root residue and 90% cow dung was the most favorable to earthworm reproduction. After earthworm composting, the total organic matter content decreased significantly, the total nutrient content increased significantly, and the seed germination index increased to a certain extent. The total nutrient content of a mixture composed of 70% fresh Pueraria root residue and 30% cow dung was 102.2 g·kg-1 and 57.7% higher than that of a mixture of 10% fresh Pueraria root residue and 90% cow dung. The earthworm bio- treatment technology can be applied to the production of fertilizer from Pueraria root residue. A mixture of 70% fresh Pueraria root residue and 30% cow dung delivers the optimal conditions for earthworm composting. |
