Field simulation block trials found that 80 mg 15% bacterium fluid, kg - 1 processing has good final repair ability, calibration degradation rate achieve results. 10% bacterium fluid 60 mg, kg - 1 and 15% bacterium fluid 80 mg, kg - 1 two processing methylene chloride chrysanthemum acid concentration increases rapidly in 5d appear to maximum after reduced and 15% bacterium fluid 60 mg, kg - 1 and 10% bacterium fluid 80 mg, kg - 1 with 2 always increase slowly and ultimately to converge. Degradation between middle product benzene oxygen radicals benzoic acid concentration in 3d appear a maximum after gradually reduce, appear a maximum value of relative lag time.

Through field simulation test ,it is found that the experimental plot treated with 15% bacterium fluid as 80 mg•kg-1 achieves better final repair ability. Correction degradation rate achieves up to 37.4%. In both treatments with 10% bacterium fluid as 60 mg•kg-1 and 15% bacterium fluid as 80 mg•kg-1 , the concentration of 2,2-dimethyl-3-(2,2-dichlorovinyl) cyclopropanecarboxylic acid reduces after rapidly reaching to the maximum value at 5d, while in both treatments with 15% bacterium fluid as 60 mg•kg-1 and 10% bacterium fluid as 80 mg•kg-1 , the concentrations of 2,2-dimethyl-3-(2,2-dichlorovinyl) cyclopropanecarboxylic acid slowly increase all the way , and finally tend to be consistent. The concentration of 3-phenoxybenzoic acid — the intermediate product in degradation process — reaches a maximum value at 3d, and then gradually reduces, for which it is relatively lagged to reach a maximum value.
