Abstract. Addition of organic wastes such as animal manures and straw is a feasible practice to alleviate soil degradation, and the mitigation is closely related to the activities of soil-dwelling fauna. In this study, the community structure of soil fauna were compared under four treatment regimes: straw only, and straw combined with the use of chicken manure, ox manure and pig manure. A total of 12459 soil fauna were captured, belonging to 23 groups. Treatments animal manure combined with straw led to increased the number of soil fauna groups and individuals, diversity index, richness index and dominance index, while reduced the evenness index of soil fauna. Compared to the other treatments, maize straw plus chicken manure and maize straw plus pig manure treatments had the largest number of soil fauna groups. Among all the treatments, Oribatida, Astigmata, Desoria and Folsomia were the dominant species, accounting for 69.94 % of the total number of individuals. Maize straw plus pig manure treatment had the largest diversity index soil fauna community. The richness index of soil fauna community in maize straw plus chicken manure and maize straw plus pig manure treatments were higher compared to other treatments. The highest dominance index of soil fauna was recorded in maize straw plus ox manure treatment. In conclusion, our findings suggested that animal manure combined with straw, especially the application of maize straw plus pig manure was the most effective treatment for enhancing soil fauna community.

畜禽粪便与秸秆复合有益土壤动物群落在旱作农业中的应用

摘要。添加动物粪便和秸秆等有机废物是缓解土壤退化的可行做法，其缓解与土壤栖息动物的活动密切相关。在这项研究中，比较了四种处理方式下土壤动物群落结构：仅稻草和稻草结合使用鸡粪、牛粪和猪粪。共捕获土壤动物12459只，分属于23个组。畜禽粪便与秸秆结合处理导致土壤动物群和个体数量、多样性指数、丰富度指数和优势度指数增加，而土壤动物均匀度指数降低。与其他处理相比，玉米秸秆加鸡粪和玉米秸秆加猪粪处理的土壤动物群数量最多。在所有的治疗中，甲螨，Astigmata，Desoria和Folsomia为优势种，占个人总数的69.94％。玉米秸秆加猪粪处理的土壤动物群落多样性指数最大。玉米秸秆+鸡粪和玉米秸秆+猪粪处理土壤动物群落丰富度指数高于其他处理。玉米秸秆加牛粪处理的土壤动物优势指数最高。总之，我们的研究结果表明，动物粪便与秸秆结合使用，尤其是玉米秸秆加猪粪的施用是增强土壤动物群落的最有效处理方法。
