Residual Film Pollution in the Eighth Division of the Xinjiang Production and Construction Corps

Abstract

This study investigated the residual film content and distribution at different soil depths in the Eighth Division of the Xinjiang Production and Construction Corps. Before spring plowing in 2019, representative fields in four areas (Anjihai, Shihezi suburbs, Mosuowan and Xiayedi) were selected for residual film collection. The average content of residual film in the Eighth Division was 104 kg/ha. The residual film content in the four areas decreased in the order Anjihai ＞ Shihezi suburbs ＞ Mosuowan ＞ Xiayedi. The average amount of residual film collected from cotton fields was greater than that from corn fields. Residual film content in the cotton field at soil depths of 0～10 and 10～30 cm was higher than that in the corn field, whereas the residual film content at a 30–50 cm soil depth in the corn field was higher than that in the cotton field. The results showed that farmers do not consider the long-term benefits, the high cost and short time of recycling, and the easy recycling of surface residual film. The shallow that the higher content of residual film, the less water in the soil of cotton. The same time, the results showed that the quantity of residual film in cotton field had greater influence on cotton quality.
