The present application relates to a kind of parabacillus (Bacillus paralicheniformis) Bacillus paralicheniformis ) HMF14, the preservation number is CGMCC No.30480.The parabacillus HMF14 of the present application can resist salt and alkali, can simultaneously antagonize fusarium oxysporum, microdochium nivale var. avenae and xanthomonas campestris pv. tridii, also has toxic effect to pratylenchus penetrans and tetranychus cinnabarinus, can effectively prevent and treat wheat take-all disease and wheat black foot disease.

The present application belongs to the field of soil remediation, and particularly relates to a method for remediation of cadmium contaminated soil. The specific technical scheme is as follows: a soil remediation method comprises the following steps: before planting economic crops, applying sulfate-reducing bacteria to the soil to be remediated; after harvesting the economic crops, planting cadmium extraction crops in the soil to be remediated. The present application provides a water-flood rotation soil remediation method which can produce while remediation. On the one hand, the biological passivation can reduce the biological availability of cadmium in the soil, thereby reducing the stress of cadmium on plants and the absorption and accumulation of cadmium by plants; on the other hand, the biological technology can strengthen the ability of nightshade to extract cadmium, thereby extracting cadmium in farmland soil.
