Core Insights - China's agricultural policy will shift towards supply-demand balance and competitiveness enhancement, aiming to establish a market-based pricing mechanism for agricultural products within the next two to three years, alongside a direct subsidy system to protect farmers' interests and promote sustainable agricultural development [5]. Group 1: Grain Production - The total grain production in China reached 1,339 billion jin in 2020, an increase of 11.3 billion jin from the previous year, marking a year-on-year growth of 0.9% and achieving a continuous harvest for the seventeenth consecutive year [4][5]. Group 2: Grain Quality and Storage - The moisture content of harvested grain is crucial for both commercial use and seed purposes, with the ideal drying level being close to the critical moisture content for microbial growth, ensuring safe storage, preventing mold and quality deterioration, and maintaining freshness, taste, and germination ability [5]. - Moisture and temperature jointly affect the respiration of grain, with low moisture levels resulting in minimal temperature impact on respiration, while increased moisture leads to significant respiratory intensity changes with temperature fluctuations [7]. Group 3: Experimental Findings - Experiments indicate that grain with a moisture content of 18%-23% experiences a rapid increase in respiration at temperatures of 50-55°C, followed by a sharp decline, whereas grain with a moisture content of 14%-16% maintains stable respiration intensity over several days at the same temperature [8].

Core Viewpoint - The article highlights the efforts of Xinzhuang Town in Suqian City to enhance village-level collective economy through the promotion of three spirits and the empowerment of party building, leading to a new path of strong villages and prosperous residents. Group 1: Resource Activation - The establishment of a land share cooperative in Xinzhuang Community and Shijiquan Village has consolidated individual farmland into a "10,000-acre rice base," resulting in a stable increase in collective income exceeding 2 million yuan [1]. Group 2: Industry Integration - The integration of agriculture and tourism in Zhenyou Community and Shanhuyuan Community has created a cluster of business types, with over 2 million visitors received this year, significantly boosting tourism revenue and establishing agri-tourism as a new growth engine for the collective economy [1]. Group 3: Development Challenges - The town party committee has implemented a "one village, one policy" support mechanism, utilizing 3,000 square meters of factory resources to aid community development, resulting in the cultivation of four strong village companies and the creation of over 300 local jobs, with an expected collective operating income of over 18 million yuan by 2025 [1].
