努力让农田“高产”又“绿色”（迈向“十五五”的创新图景）

Core Viewpoint - The article emphasizes the importance of food security in China and the need to enhance agricultural production capacity and quality while ensuring efficient resource utilization and environmental protection [1]. Group 1: Agricultural Innovations - The "Green Ton Half Grain" initiative aims to increase the annual yield of grain crops to over 1.5 tons per acre without increasing resource costs [1]. - In Quzhou, the annual grain yield was around 700 kilograms in the early 2000s, with traditional farming methods leading to soil salinization and compaction [1]. - The research team focuses on soil-crop systems, aiming for "uniform, robust, and synchronized" seedlings through comprehensive technological innovations in soil, fertilizer, water, seeds, and management [1]. Group 2: Integrated Production Techniques - The "Winter Wheat - Summer Corn" integrated green production technology significantly reduces irrigation water usage and ensures balanced nutrient supply, laying the foundation for increased yield and soil restoration [2]. - In the Quzhou demonstration area, the annual yield of wheat and corn reached 1,522 kilograms, achieving water savings of 30%, fertilizer savings of 20%, and a 46% reduction in nitrogen loss [2]. - The "Green Ton Half Grain" model has been implemented in 18 demonstration sites across 7 provinces, showing adaptability and replicability, with yields reaching 1.82 tons in Qixian and 1.84 tons in Linzhi [2]. Group 3: Sustainable Agricultural Development - Soil health is crucial for sustainable agricultural development, as improper soil use can lead to decreased yields and a vicious cycle of increasing inputs with declining soil fertility [2]. - The introduction of the "plant-soil feedback" theory aims to maintain soil health and enhance plant growth, complemented by variety breeding and management innovations [2]. Group 4: Future Outlook - The "Green Ton Half Grain" model will continue to be promoted, focusing on creating a food production pattern that integrates different regional cropping systems [3]. - The integration of modern technologies such as artificial intelligence, big data, and the Internet of Things with agricultural practices aims to achieve precise management of farmland [3].
