【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β-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、β-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β-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。
[Abstract]:Soil enzyme activity is an important basis for evaluating soil quality. In order to elucidate the effects of pig manure, biogas liquid and functional biological earthworm on soil carbon cycle related enzyme activity and microbial biomass in the process of fertilizing poor soil. Through field positioning tests, No fertilization treatment, pig manure treatment, pig manure biogas treatment, pig manure biogas treatment, pig manure biogas treatment, pig manure biogas liquid treatment, pig manure biogas liquid treatment, pig manure biogas liquid treatment, pig manure biogas liquid treatment and pig manure biogas liquid earthworm treatment, and pig manure biogas liquid earthworm treatment, respectively. The results showed that compared with CK, the activities of amylase and 尾 -glucosidase increased by 10.0 and 50.5 and 30.2%, respectively, and the microbial biomass (MBCc) increased by 58.0124, sucrase, sucrase, compared with PMS. The activities of amylase and 尾 -glucosidase were increased by 95.2m216162and 22.3and 66.8and 65.30.The above results showed that the application of pig farm waste could increase the activities of amylase and 尾 -glucosidase significantly, and the application of earthworms and fungicides could promote the effect. The results showed that the application of pig farm waste could increase the activity of amylase and 尾 -glucosidase in soil, and the application of earthworms and fungicides could promote the effect. At the same time, the content of MBC and the activity of sucrase in soil were increased, and there was a synergistic relationship between earthworm and fungicides.
