水质向好 农业增值 农民增收安徽巢湖全链条一体化防治农业面源污染

Core Insights - The project "Integrated Prevention and Intelligent Control Technology for Agricultural Non-Point Source Pollution in the Chaohu Lake Basin" aims to improve water quality, increase agricultural value, and enhance farmers' income through a comprehensive approach [1][4]. Group 1: Project Overview - The project is led by Anhui Agricultural University in collaboration with ten other domestic institutions, focusing on a full-chain approach to tackle agricultural non-point source pollution [1]. - The project team has developed an information technology platform for precise diagnosis of agricultural pollution sources, completing data collection of 1.5 million entries across 5 cities and 17 counties [2]. Group 2: Technological Innovations - The team has created low-cost, portable monitoring equipment for nitrogen and phosphorus, along with a three-dimensional monitoring network using drones and satellites [2]. - New technologies include specialized fertilizers that reduce chemical fertilizer use by 20% without affecting yield, and pesticide reduction techniques that enhance product quality while controlling pests [3]. Group 3: Implementation and Impact - The project employs a grassroots promotion model, with over 20 agricultural educators living in villages to demonstrate new technologies directly to farmers [4]. - The implementation of new techniques has resulted in cost savings of approximately 20 yuan per mu for fertilizers and 30 yuan for labor, with an estimated increase in income of 50 yuan per mu due to improved yield and quality [4]. - Over 20,000 mu have been promoted with these new technologies, leading to a reduction of 1,648 tons of nitrogen and phosphorus fertilizers and a decrease of 121 tons in emissions [5].
