Although environmental degradable film has been degraded from block disintegration to “rice water” appearance “dissolved” into soil environment under the natural environmental conditions effects of light, temperature, water, atmosphere and microorganisms, the "dissolved" plastic film still have serious pollution to environment which has become new hotspot of discussion. In this study, the orthogonal test L9(34) methods was applied to investigate the effects of four factors (the molecular weight of polyethylene, the amount of polyethylene residue, soil type and depth) on the soil phosphatase activities. The results indicate that the mean activity of phosphatase is 2135.7 μg /(h＊g),1472.97μg/(h＊g) and 1687.23μg/(h＊g) in the seeding, flowering and mature stage of brasscia juncea in clay soil, respectively, and 2.54, 1.56, 1.22 fold in that of sandy soil and 1.32, 0.87, 0.79 in that of loam, respectively.
