NOVELTY - Method for biologically recovering soil polluted by organophosphorus pesticide, involves preparing Glomus intraradices as microbial inoculating agent, inoculating agent into polluted soil, seeding seeds of host plant, allowing seeds to grow, cutting upper part of host plant, inoculating agent in soil to-be-recovered, planting rapidly growing plant, clearing polluted soil, inoculating amplified intraradices agent in soil, planting seeds of rapidly growing plant, transferring plant to soil, growing plant for 2-3 months, and planting obtained plant.    USE - The method is useful for biologically recovering soil polluted by organophosphorus pesticide.    ADVANTAGE - The method can reduce pesticide residue in agricultural product, reduce transfer of pesticide to water and air and reduce harm to health of human body, and is simple and environmentally-friendly.    DETAILED DESCRIPTION - Method for biologically recovering soil polluted by organophosphorus pesticide, involves preparing Glomus intraradices as microbial inoculating agent, inoculating 3-5% of the agent into the polluted soil by layer implementation method or mixed implementation method to agitate the uniformly, adding 18-22% of water into the soil, seeding seeds of the host plant chosen from sudan grass, whitetip clover and corn in soil, allowing the seeds to grow for 3-4 months, cutting upper part of the host plant, shearing the root segment and mixing the segments uniformly, where the air-dried soil with host plant root segment, intraradices spore and outside-root hypha are used as intraradices agent, inoculating the agent in the soil to-be-recovered, planting rapidly growing plant, clearing the soil polluted by organophosphorus pesticide, inoculating the amplified intraradices agent in the soil, where amount of intraradices agent in each unit area is 200-300 kg, the intraradices agent are sowed in cavity or in layer or both, planting the seeds of the quickly growing plant with density of 10000-15000/unit area or rooting the quickly growing plant in the intraradices agent, transferring the plant to the soil to-be-recovered, growing the plant for 2-3 months, adding fertilizer to the plants, obtaining plant after the plant grows for 2-3 months, and planting the obtained plant in spring, summer or autumn, where plant cannot grow normally in winter.
