Abstract
Through greenhouse pots experiments, an orthogonal test method was employed here to study the optimum degradation conditions of cold-adapted degrading bacterial and the winter wheat. This orthogonal experiment selected four influencing factors: oil content, bacteria amount, soil moisture content and fertilizer. The results showed that in different stages, the optimum degradation conditions were different. Oil content and the bacterial amount were the two most important factors that influenced the degradation of petroleum hydrocarbons. The impact of fertilizers on the degradation rate increased with time, while water content on the degradation rate decreased with time.
