A strain of soil nitrate conversion bacteria is separated from greenhouse soil for protected planning for many years, and is called as Bacillus pumilus through classification, the number of the bacterial strain is SrN7, and the preservation number is CGMCC No. 9685. The microorganism strain is mixed with bran to prepare a microorganism bacterium agent after activation, enlarging cultivation and fermentation treatment, and the obtained microorganism bacterium agent is applied to soil at the roots of target vegetables. The obtained bacterium agent is a pure biological agent and is harmless for the body and the environmental health, the concentration of nitrate in protected soil can be reduced, so that the content of the nitrate in vegetable bodies is reduced, the plant growth can be promoted, and the basic physicochemical property of the soil is improved; compared with other methods for reducing the nitrate of the protected soil, under the precondition of not influencing normal production, the content of the nitrate in the soil can be reduced while production, and the effect of repairing while production is achieved.
