摘要
介绍棉田残膜污染危害的主要表现,包括降低棉田肥力、影响棉种发芽和棉花根系生长、影响棉田机具作业、影响机采棉质量等;通过对比提出机械化残膜回收是目前棉田残膜污染治理的最佳方式;对残膜机械化回收的各主要作业环节进行了简要介绍,总结了棉田残膜机械化回收存在的主要问题。
Main expressions of remnant film pollution in cotton fields are elaborated,including degraded cotton field fertility,weakened cotton seed sprouting and root growth,affected machinery operation,impaired quality of machine-harvested cotton,et al.Mechanized residual film recovery is proposed to be the best way to deal with this pollution in cotton fields by comparisons.The major links of residual plastic films mechanized recycling are introduced,and the existing problems during the recycling process are summarized in this paper.
