中文摘要	土壤酶活性是评价土壤质量的重要依据。为阐明猪场废弃物猪粪、沼液和功能生物蚯蚓、菌剂在培肥贫瘠土壤过程中对土壤碳循环相关酶活性及微生物量的影响,通过野外定位试验,设置不施肥处理(CK)、施猪粪处理(Pm)、施猪粪+沼液处理[(Pm+S)/ T]、施猪粪+沼液+蚯蚓处理(Te)、施猪粪+沼液+菌剂处理(Tb)和施猪粪+沼液+蚯蚓+菌剂处理[T(e+b)],阐释各外源物质的作用以及功能生物间的协作关系。结果表明:与CK相比,Pm处理淀粉酶和beta-葡萄糖苷酶活性分别增强了10.0%~50.5%、30.2%~55.9%;与Pm+S相比,T(e+b)处理的微生物生物量碳(MBC)含量增加了58.0%~124%,蔗糖酶、淀粉酶、beta-葡萄糖苷酶活性分别增强了95.2%~216%、22.3%~66.8%、65.3%~118%。以上结果说明,施用猪场废弃物对土壤淀粉酶和beta-葡萄糖苷酶活性增效显著;配施蚯蚓和菌剂可促进该效果,同时提高土壤MBC含量和增强蔗糖酶活性,且蚯蚓和菌剂间存在协同关系。
英文摘要	Livestock wastes from intensive agricultural production are extensively utilized as organic fertilizers in soils. The degradation of organic wastes and the release of nutrients are closely associated with soil microbial activity. Earthworms and bacteria in soil may accelerate the transformation of organic matter via digestion and assimilation. Soil microbial biomass and enzyme activities are important indicators of soil quality. To elucidate the effects of pig manure, biogas slurry, and functional organisms on the microbial biomass carbon(MBC)and the activities of enzymes related to C cycling, a field experiment was conducted with six treatments of control(CK), pig manure(Pm), pig manure + slurry[(Pm+S)/T], manure + slurry + earthworms(Te), manure + slurry + phosphate-solubilizing bacteria(Tb), and manure + slurry + earthworms + bacteria[T(e+b)]. The former three treatments were to investigate the roles of the exogenous wastes on the activities of enzymes related to C cycling. The latter three were to further evaluate the collaborative effects of functional organisms. Compared with those in CK, the activities of amylase and beta-glucosidase increased by 10.0%~50.53% and 30.2%~55.9%, respectively, in Pm. Compared with those in Pm+S, the contents of MBC, invertase, amylase, and beta-glucosidase activity by 58.0%~124%, 95.2%~216 %, 22.3%~66.8%, and 65.3%~ 118%, respectively, in T(e+b). The results indicated that pig waste had a significant effect on the activities of amylase and beta-glucosidase in the arid-slope soil. Furthermore, the application of earthworms and phosphate-solubilizing bacteria stimulated the amylase and beta-glucosidase activities. Meanwhile, soil MBC and invertase activity were also enhanced in T (e+b), suggesting a synergistic effect of earthworms and phosphate-solubilizing bacteria on these two soil properties. In contrast, the addition of earthworms or phosphate-solubilizing bacteria alone did not have a significant effect on soil enzyme activities. These results suggest that the combined addition of earthworms and phosphate- solubilizing bacteria was an efficient strategy for stimulating the transformation of manure organic matter and the cycling of nutrients in arid hillside soils.
