160Mu farm land, of which the soil was seriously contaminated by heavy metals, organic pollutants, and along with packing problems and low effective of fertilizers problems, was chosen as the anti-pollution technology study sample. To resolve those problems, we fully use local resources to make a recovery measure by soli self-purification combined with bioremediation.The whole sample farm land was divided into 4 sub samples, each with an area 150Mu, and named Sample A, B, C, D of which Sample D will take as reference object. Sample D will take use of free-pollutant planting skill, and no requirement of crops.(一) Measure one:for heavy metals pollutants problem; we interplant the Agaricusbisporus and cucumber. Considering the Agaricusbisporus is very sensitive to the temperature, greenhouse cultivation may be needed for some cold winter place and however this kind of cultivation can't be guaranteed everywhere, thus, we also prepared an alternative choice-flower planting.(二) Measure two:for packing problems and low effective of fertilizers problems, we use PAM in the rape field and take straw returning to improve the soil quality.(三) Measure three : for the heavy organic pollutants, we use ferment fertilizer-EM skill in the vegetable field to resolve this problems.(四) For some micro pollutant resource, we use the principle of Bio-diversity to resolve this problem. And this also confirms to the principle High gain with smallest investment.(五) Researching anti-pollutant technology, training skilled person and providing technology support can help widely spread the anti-pollutant planting ways and more area of pollutant soil can be treated.According to our site convey and monitor data analysis, those measures works. The soil quality is improved; the ratio of heavy metals decreased; the ration of nitrogen and phosphorus in the organic materials is adjusted against the reference.
