生防细菌对人参连作土壤性质及细菌群落结构的影响
Effects of Biocontrol Bacteria on Soil Properties and Bacterial Community Structure of Ginseng Continuous Cropping
摘要
Abstract
In order to investigate the effect of biocontrol bacterial on the microecology of ginseng continuous cropping soil,a biocontrol bacterial treatment experiment was conducted in the field.Chemical analysis and high-throughput sequencing technology were used to study the changes in soil physicochemical properties,soil enzyme activities,and bacterial community.The results showed that the application of biocontrol bacteria significantly decreased soil electric conductivity,and increased soil pH,the contents of organic matter,available nitrogen,available phosphorus and the activities of soil urease,soil sucrase,and soil acid phosphatase,with an increase of 9.00%in soil organic matter content and an increase of 19.42%in soil sucrase activity.Bacterial taxonomy analysis divided soil bacterial communities into 39 phyla,124 classes,279 orders,424 families,and 774 genera.Biocontrol bacteria significantly increased the ACE index and Chao index of soil bacteria.Correlation analysis showed that pH,organic matter,available nitrogen,sucrase,urease were significantly positively correlated with Arthrobacter,and significantly negatively correlated with Bradyrhizobium and Microlunatus;available phosphorus content was significantly positively correlated with Candidatus_Xiphinemabacter,RB41,and significantly negatively correlated with Candidatus_Udaeobacter,Arthrobacter;and there was significantly negative correlation between acid phosphatase and Mycobacterium.In summary,biocontrol bacteria stimulated the growth and reproduction of beneficial microorganisms in soil,increased the fertility and enzyme activity of the soil,and improved the soil nutritional status.Therefore,biocontrol bacteria should be expected to become an effective way to repair degraded soil.关键词
