秸秆变身“金疙瘩” 农科专家让农业废弃物“香”起来

Core Viewpoint - The recent training session in Taicang City focused on the comprehensive utilization of agricultural straw, showcasing innovative technologies that transform waste into valuable resources, thereby promoting green development in rural areas [1][2]. Group 1: Technological Innovations - The Jiangsu Academy of Agricultural Sciences introduced technologies for the "fertilizer, energy, feed, substrate, and raw material" utilization of straw, aiming to convert agricultural waste into valuable resources [1]. - The research team developed a substrate block/tray from straw that can replace traditional non-degradable plastic seedling trays, enhancing transplant efficiency and promoting straw recycling [1]. - A fully biodegradable film made from straw was created to address traditional film pollution, providing multiple benefits such as environmental protection, temperature increase, moisture retention, and weed suppression [1]. Group 2: Fertilizer Utilization - The principle of "reasonable organic-inorganic ratio" was emphasized for the production of mature organic fertilizer from straw, which improves soil structure and quickly supplements nutrients [1]. - The "one factory, six centers" project in Taicang, involving a commercial fertilizer factory and six initial composting treatment centers, aims to enhance the efficiency and environmental friendliness of straw fertilizer utilization [1]. Group 3: Straw Utilization Statistics - Taicang has over 160,000 tons of straw annually, with a collection capacity exceeding 100,000 tons [2]. - The comprehensive utilization rate of straw reached 100% in 2024, with the straw leaving the field rate surpassing 16.8% [2]. - Plans are in place to increase the leaving rate by nearly 8 percentage points this year, establishing an integrated model for collection, storage, transportation, and high-value utilization [2].
