Group 1 - The core idea is that Huai'an is focusing on developing ecological agriculture by creating a high-quality rice industry cluster through innovative use of river sediment [1][2]. - The research team has developed a rice seedling nutrient soil product primarily made from river sediment, which addresses traditional seedling cultivation issues and promotes a new model of "light and simplified seedling cultivation" [2][3]. - The new nutrient soil allows for a significant reduction in the steps required for seedling preparation, saving labor costs and eliminating the need for additional fertilizers or conditioning agents [2][3]. Group 2 - The technology has achieved large-scale resource utilization of river dredging in agriculture, establishing an ecological recycling model that integrates dredging, resource regeneration, and agricultural application [3]. - The research team is committed to building a complete industrial chain model that connects river dredging, nutrient soil production, and green ecological planting, aiming to enhance the efficiency of technology transfer [3].
