在棉田土壤中，经粗略拣拾后，残留地膜累计量为３．５～４．９ｋｇ·ｈｍ￣（－２）·ａ￣（－１）。当残留量达３６０ｋｇ·ｈｍ￣（－２）·ａ￣（－１）以上时，对土壤水分上下移动过度产生明显减慢影响。残膜在分解过程中，土壤有机质测值提高。对其他土壤化学元素无大的影响。土壤中残膜会阻碍主根垂直延伸生长，迫使形成“鸡爪根”、“倾斜根”和“多侧根”，但对棉株产量尚未造成明显影响。随着残膜量的积累，对土壤环境的污染是存在的，务必引起足够的重视。
In the soil of cotton field, after the rough pick-up, the residual film accumulated amount is 3.5 ~ 4.9kg · hm ~ (-2) · a ~ (-1). When the residual amount is more than 360kg · hm ~ (-2) · a ~ (-1), there is a significant slowdown in the movement of soil moisture up and down. In the process of decomposition of residual film, the measured value of soil organic matter increased. No other major impact on soil chemical elements. The residual membrane in the soil hinders the vertical growth of the main root and forces the formation of “chicken root”, “tilted root” and “multi-lateral root”, but no significant effect on cotton yield. With the accumulation of residual film, the pollution of the soil environment is there, must pay enough attention.
