不同土壤菌配置对赣南山区土壤酶活性及微生物数量的影响OA

With the continuous development of China's economic construction,site restoration in the later stage of project construction is an important link to protect the environment and maintain ecological balance.In order to solve this problem,the soil bacteria configuration and guest soil spray seeding technology were used to restore the trace.different soil bacteria configurations(DL1+DL2,DL1+DL3,DL2+DL3,and DL1+DL2+DL3)were added to the spray seeding substrate and laid to the slope of the mountain area of southern Jiangxi.In order to solve the problem of slope restoration in the later stage of mountain slope in southern Jiangxi,the optimal allocation model of soil bacteria was put forward.The results showed that the application of soil bacteria promoted the activity of soil microorganisms and accelerated the biochemical reaction in soil.the addition of soil bacteria could significantly increase the activities of catalase,sucrase,neutral phosphatase and cellulase,and the total number of fungi,bacteria,acti-nomycetes and microorganisms in the slope soil of southern Jiangxi province.Among them,the DL1+DL2 configuration mode of soil bacteria has the most obvious effect on improving the soil enzyme activity and the number of microorganisms in the mountainous area of southern Jiangxi.
