Research on Post-Harvest Management Technology to Improve Cotton Quality

Cotton is an important cash crop worldwide, and its production is related to the livelihoods of millions of farmers. However, cotton quality faces many challenges in the post-harvest stage, such as increased impurities due to improper harvesting methods and fiber deterioration caused by poor storage. This study focuses on improving cotton quality through post-harvest management technology. It systematically analyzes the key factors affecting cotton post-harvest quality, including harvesting time and methods, field processing and transportation, storage conditions, etc.; reviews advanced post-harvest processing technologies, such as cotton ginning process innovation, fiber grading and sorting, and moisture control methods; explores new technologies for cotton quality assessment and monitoring, including fiber quality parameter testing, digital monitoring, traceability systems, and quality certification mechanisms; evaluates the sustainability and economic impact of post-harvest technology, and analyzes it from the aspects of cost-effectiveness, environmental friendliness, and social effects; and takes Xinjiang as a case to introduce regional challenges, technology introduction, and its effectiveness. Finally, the future development direction of cotton post-harvest management technology is prospected, such as digital intelligent system integration, localized customization, and policy and institutional support. This study aims to provide a reference for improving cotton quality and value and promote the high-quality development of the cotton industry chain.
