四川在成都平原开建“吨粮田”，首批两百万亩 一篇粮食高产稳产的大文章

Core Viewpoint - The construction of "ton grain fields" in Sichuan aims to enhance grain production stability and innovation through technological support and improved agricultural practices, focusing on achieving a yield of one ton per mu of arable land annually [2][3][4]. Group 1: "Ton Grain Field" Construction - The "ton grain field" initiative emphasizes the assurance of high and stable grain production through resource allocation, innovative models, and the promotion of new technologies and varieties [2][3]. - Sichuan plans to deploy technology support teams in the "ton grain field" areas to provide comprehensive agricultural services from planting to harvesting [3]. - The average grain yield in Sichuan was below 380 kg per mu last year, and the province has initiated the construction of 2 million mu of "ton grain fields" this year, primarily in the Chengdu Plain [2][4]. Group 2: Strategic Importance and Implementation - The "ton grain field" project is part of Sichuan's strategy to build a higher-level "Tianfu Granary" and ensure the supply of essential primary products for the nation [4]. - The province has previously launched the "Tianfu Granary·Hundred Counties Thousand Pieces" initiative, which increased grain yield by 4.1 kg per mu through high-yield competitions and the promotion of quality seeds and techniques [4]. - Sichuan's agricultural authorities plan to complete the construction scheme and site selection for "ton grain fields" within the year [4]. Group 3: Additional Measures for Grain Production - In addition to the "ton grain field" initiative, Sichuan is implementing a comprehensive strategy to stabilize and increase grain production, including optimizing 1.15 million mu of low-yield farmland [5]. - The province has raised the subsidy standard for large grain producers in hilly and mountainous areas to 200 yuan per mu and plans to establish 1,000 high-yield demonstration plots across 115 counties [5]. - A total of 354 expert service teams will be formed to provide on-the-ground guidance for production [5].
