菌糠源生物堆肥对黄瓜种植土壤微生物活性、数量和多样性的影响
Effects of biocompost derived from spent mushroom substrates on soil microbial activity,abundance and diversity in cucumber field
摘要
Abstract
Using agricultural waste organic materials as fertilizer is beneficial to soil physical,chemical and micro-biological properties.In this study,we examined the effects of application of chemical fertilizer(CK),traditional compost(OF),and vermicompost(VCF)on chemical properties,enzyme activities,and the number and diversity of microbial communities in cucumber planting soil.The results showed that OF and VCF treatments significantly increased soil pH,organic carbon content,and total nitrogen content,the activities of soil dehydrogenase,α-gluco-sidase,alkaline phosphomonoesterase and phosphodiesterase,and the abundance and alpha diversity of soil bacteri-a.In contrast,they had no significant effect on the abundance and alpha diversity of soil fungi.OF and VCF treat-ments altered soil microbial community structure,bacterial and fungal community composition,and significantly reduced the relative abundances of Mizugakiibacter,Rhodanobacter,and Penicillium.Richness Chao1 and α-diver-sity Shannon index of soil bacterial community were significantly correlated with pH value,organic carbon content,total nitrogen content,and phosphodiesterase activity.Results of redundancy analysis showed that total soil potassi-um content,β-glucosidase and acid phosphomonoesterase activities were the key factors affecting soil bacterial com-munity,while soil α-glucosidase activity was the key factor affecting soil fungal community.Both traditional com-posting and vermicomposting improved the chemical properties and enzyme activities of soil,changed microbial community structure,and increased microbial community diversity.关键词
