Cotton Genomics and Genetics 2025, Vol.16, No.2, 95-106 http://cropscipublisher.com/index.php/cgg 104 cotton harvesting seasons in various producing areas are different. We can fully explore cross-regional collaboration, such as transporting seed cotton harvested in the mainland to large-scale processing bases in Xinjiang for centralized processing, and using its advanced equipment and low-cost advantages to achieve complementary advantages. These differentiated and coordinated management ideas will make post-harvest technology more practical and maximize its benefits. 7.3 Policy and institutional support The promotion of cotton post-harvest management technology is inseparable from policy support and the promotion of industry organizations. First, the government should continue to increase support for key links after harvesting, such as improving agricultural machinery subsidy policies, including advanced cleaning equipment and drying and storage facilities in the subsidy catalog, and lowering the threshold for cotton farmers and enterprises to adopt new technologies; tax exemptions or special subsidies should be given for cotton processing by-product utilization projects to encourage enterprises to carry out circular economy practices (Wang et al., 2022). Secondly, formulate and revise relevant standards and specifications to guide technology application. For example, improve the national standard for cotton quality grading, increase the weight of digital detection indicators; formulate cotton foreign fiber content limit standards and detection methods; promote cotton traceability standards, etc. The introduction of these standards will provide a basis for the application of new technologies and improve the acceptance of all parties. In addition, industry associations and scientific research institutes should play a bridging role and increase technical training and demonstration. By holding on-site observations and technical exchanges, mature post-harvest management experience will be promoted in cotton-growing areas across the country, so that more cotton farmers will realize the importance of "growing good cotton and managing it well". At the international level, China can also participate in and lead multilateral cooperation to improve cotton quality, such as cooperating with the International Cotton Advisory Committee (ICAC) and fiber inspection agencies to develop a global unified quality traceability system and certification, so that Chinese cotton can better integrate into the sustainable cotton supply chain. In short, policy and institutional support will provide a good external environment for the development of post-harvest cotton technology in the future and accelerate the transformation and application of scientific and technological achievements. 8 Conclusion Cotton post-harvest management technology is crucial to maintaining and improving cotton quality. This study systematically analyzed the main factors affecting cotton post-harvest quality, sorted out the technological progress in cotton ginning technology, fiber grading, moisture control, quality monitoring, etc. in recent years, and verified the effectiveness of technical measures in combination with Xinjiang cases. The study shows that by optimizing the harvesting method, strictly controlling the impurities and moisture content, using advanced cotton ginning and grading equipment, and improving the quality monitoring and traceability system, the cleanliness and consistency of cotton fiber quality can be significantly improved. These technical measures not only improve cotton quality, but also reflect comprehensive benefits in cost savings and environmental protection, creating conditions for cotton farmers to increase income and industrial upgrading. Of course, different regions need to take local conditions into account when promoting post-harvest management technology, taking into account economic feasibility and social impact. Against the background of rapid development of science and technology, cotton post-harvest management is moving towards digitalization, intelligence, and standardization. In the future, by integrating the Internet of Things and artificial intelligence, accurate control and quality prediction of the entire post-harvest process of cotton can be achieved, further reducing human errors and losses. At the same time, strengthening policy support and international cooperation, and establishing and improving quality standards and certification systems will help consolidate the results of cotton quality improvement and expand its market influence. In short, continuously improving the level of cotton post-harvest management technology is of great practical significance for ensuring the healthy development of the cotton textile industry and enhancing the competitiveness of my country's cotton in the international market. By giving equal importance to technology and management, and innovation and promotion, all links in the cotton industry chain will work more closely together to achieve high-quality, efficient and sustainable development.
