To serve the national strategy of ecological protection and high-quality development in the Yellow River Basin, and to promote the revitalization of inland cotton regions and enhance cotton industry quality and efficiency, the Jining Institute of Quality & Metrology Inspection in collaboration with multiple stakeholders, conducted a pilot project to monitor production processand and enhance the quality of cotton in the region from 2023 to 2024. The pilot project innovatively established a "government-industry-university-research-application" collaborative mechanism, leveraging three core measures (superior cultivar selection, equipment renovation and on-site monitoring and standard setting) to built a full-chain quality monitoring system for cotton and operationalize the "whole-chain standardization of cotton industry" model. The key outcomes are as follows. Firstly, Lumianyan 40 exhibited superior comprehensive quality, and its yield reached 351 kg per mu,while that of the control variety is 142 kg per mu. Among it, the proportion of white cotton in terms of color grade accounts for 81.6%, with an average length of 28.5 mm and an average length uniformity index of 82.8%. Secondly, three local standards of Shandong Province were formulated, and green, high-quality and efficient production technologies were promoted, achieving the effect of "three reductions and three increases". Finally, the methodology of "data-driven closed-loop optimization" was summarized. By collecting full-chain data, conducting correlation analysis of multiple factors, establishing quality maps, and reversely guiding production, core production elements such as superior varieties, daytime processing, and controlled dosage of defoliants were identified. In the future, the Jining Institute of Quality & Metrology Inspection will extend the monitoring network to more regions, promote the cross-regional dissemination of experience, and provide “Shandong experience” for improving the quality and efficiency of the national cotton industry.

The big data platforms for all links of the cotton industry have been gradually established and improved, which has laid the necessary foundation for the intensive inspection of seed cotton. The establishment of scientific, efficient and accurate seed cotton inspection results and their data platform is of great significance. Firstly, it can gradually integrate the various processes of seed cotton inspection in processing enterprises, aiming to reduce their acquisition costs and build a platform for both parties to the transaction to determine the price based on quality. Secondly, processing enterprises can rely on accurate inspection results to scientifically and effectively adjust the processing technology, truly achieve the effect of "matching vehicles according to cotton", and provide data support for further improving the quality of cotton processing. Thirdly, as a supplementary link in the big data platform chain of the cotton industry, the seed cotton inspection data platform can not only provide government departments with accurate monitoring data on the quality and variety of seed cotton, but also provide a data basis for local cotton planting and production decisions, which is of reference significance for standardizing the cotton seed market and selecting cotton seeds suitable for planting in the region.

The climate in Guangdong region is hot and humid. After being stored for a long time, the quality of the reserved cotton will undergo variations. Exploring the impact of the quality variations of the reserved cotton on the quality indicators of cotton is helpful for improving the management level of scientific cotton storage.Through experimental design in this paper, the scenario of compressed storage of cotton under pressure is simulated under standardized and controlled warehousing conditions. As the quality variation of cotton originates from multiple factors, this paper uses SPSSPRO software for multiple linear regression analysis, incorporates influencing factors such as storage environment temperature, humidity, storage time, moisture regain, and storage layer height into the regression analysis, and adopts the stepwise regression method to explore the impact of quality variation of Guangdong reserved cotton on cotton quality. The results show that the quality variation of reserved cotton has a significant impact on yellowness and reflectance, with yellowness increasing, reflectance decreasing, breaking tenacity slightly decreasing, while length, length uniformity, and micronaire value are almost unaffected, maintaining the same quality level before and after storage. Finally, this paper puts forward the preliminary concept of cotton storage variation index, aiming to quantify the quality variation degree of reserved cotton and provide data reference for scientific cotton storage.

Based on big data analysis of imported cotton quality inspections from 2022 to 2024, this study examines the primary quality indicator ranges of China's imported cotton and summarizes the distribution and trends of different quality grades.

The compliance rates for different indicators fluctuated slightly across periods. Overall, the main quality grades of imported cotton from 2022 to 2024 accounted for a high proportion with strong consistency, and the compliance rates for key indicator ranges were high.

To ensure the accuracy and authenticity of the notarized inspection data of Xinjiang supervised cotton in Kashir region in 2023, the cotton with a difference of more than 100 kg between the scheduled weight and the weighed weight was retested and the official weight was recalculated. The results showed that 97.35% of the cotton had a reduced gross weight in the retest, the moisture regain difference was concentrated between -0.3% and 0.2%, and the proportion of the difference in official weight to the original measured value was within the range of -0.9% to 0.4%. The influence of storage time and environmental temperature and humidity, inspection factors, processing enterprises, human factors, and packaging methods on the official weight was discussed. Combined with the actual situation of the notarized inspection of Xinjiang supervised cotton, relevant suggestions were put forward.

This study established an evaluation system for the antibacterial performance of superabsorbent polymer (SAP), investigating the impacts of sterilization methods, contact time, and sampling techniques on test results. Using Staphylococcus aureus (ATCC 6538) as test strain, we compared high-pressure steam sterilization (121℃ 30 min) with ultraviolet sterilization (254 nm, 30 min), set contact durations at 1 h, 2 h, 24 h, and employed both fixed-ratio and dynamic quantitative sampling methods. Results demonstrated: (1) The UV sterilization group showed significantly higher antibacterial rate (58.01%) than the steam sterilization group (48.66%, p<0.05); (2) Prolonged contact time to 24h enhanced antibacterial rate to 80.90%, representing a 37.62% increase compared to 1 h group; (3) Dynamic sampling method achieved 63.50% antibacterial rate, 3.45% higher than fixed method, with superior data consistency. This research indicates that UV sterilization better preserves material antimicrobial activity, contact duration positively correlates with antibacterial efficacy, and dynamic quantitative sampling provides more objective assessment of antibacterial properties.

To address the issues of large errors in manual sample placement, low reproducibility, and low efficiency existing in the current detection methods for cotton fiber short fiber content, a novel automated sample placement device for cotton short fiber content has been developed. This device adopts a modular architecture, consisting of three core modules (cotton clamping module, cotton feeding module, and test bench module) and an intelligent control unit. The cotton clamping module achieves accurate gripping and transfer of cotton slivers through high-precision pneumatic grippers and linear guide rails. The cotton feeding module completes secondary width-fixing finishing of cotton slivers by means of a bell mouth, a belt conveyor, and a clamping and narrowing structure. The test bench module ensures the repeatability of sample placement positions by integrating long sliding table guide rails, a lifting comb needle table, and calibration with dual position sensors. In terms of control, a two-level architecture of "host computer-domestic MCU" is adopted. Combined with flat-head contact position sensors and reflective infrared grating sensors, it realizes precise control and efficient coordination.
