Effects of Soil Treatments on Rhizosphere Soil Microorganisms in Continuous Cropping of Codonopsis Pilosula
To explore the measures to alleviate the continuous cropping obstacle of codonopsis pilosula,the continuous cropping of codonopsis pilosula was taken as the research object,and different soil treatments were used to analyze the effects of different soil treatments on the rhizosphere soil microorganisms of codonopsis pilosula,the mitigation effect of continuous cropping obstacle of codonopsis pilosula was studied.The results showed that AWCD value of codonopsis pilosula rhizosphere soil treated with Kekebao + Junyiduo was significantly higher than CK.The Shannon diversity index,Evenness index and McIntosh index were the highest,and the utilization ability of various carbon sources in the soil was the best.The results showed that the combined treatment of Kekebao + Junyiduo could significantly improve the microbial diversity,microbial metabolic capacity and community function in the rhizosphere soil of continuous cropping codonopsis pilosula,balance the microbial community structure,effectively alleviating the continuous cropping obstacle of codonopsis pilosula.
