Abstract:

With the increasing years of plastic mulch usage, the "white pollution" caused by its massive residues has significantly deteriorated farmland soil quality and agricultural production, posing a substantial threat to rural ecological safety. This study analyzes the changing trends of plastic mulch usage and covered area from 2001-2021, and the status and recycling of mulch residues from 2019-2022 based on data from China's Rural Statistical Yearbook and fixed-point monitoring. It suggests enhancing farmers' environmental awareness, establishing a mulch recycling system, strengthening monitoring and evaluation, and improving the mulch residue monitoring network. The findings provide data support for the scientific use and recycling of farmland plastic mulch in Guizhou Province and serve as a reference for residue pollution control, fostering high-quality green agricultural development.
