Core Viewpoint - The successful completion of the national "14th Five-Year" key research and development project led by Xinyan Group marks a significant achievement in agricultural pollution control technology [1][6]. Group 1: Project Overview - The project, initiated in 2021, involved a transition from being a participant to a host, reflecting a four-year journey of overcoming challenges in organization, research management, and execution [3][8]. - The research team focused on nitrogen source pollution control in intensive agricultural areas, conducting mechanism studies, product development, and technology integration [3][8]. Group 2: Achievements and Innovations - The project resulted in the development of four new products, including "Super Control" coated urea and "Water Touch Membrane 3.0" slow-release fertilizer, creating a comprehensive technology system for nitrogen reduction and efficient utilization [3][10]. - Demonstration results in the Huanghuaihai region showed that the integrated "product + agronomy + machinery" model improved nitrogen fertilizer utilization to over 43%, reduced ammonia volatilization by over 49%, and increased crop yields by 5% to 15%, with economic benefits rising by 10% to 24% [10]. Group 3: Collaborative Efforts and Future Directions - The project led to the promotion of 18 research professionals and the joint training of 38 master's and doctoral students, fostering a stable collaborative innovation network across institutions [10]. - Xinyan Group aims to continue its open cooperation with universities and research institutes to promote the transformation of outstanding research results, contributing to the high-quality green development of agriculture in China [10].
