近年来，我们在河北曲周的中低产盐碱地上，开展了"绿色吨半粮"创建工程。具体来说，就是在不增加 甚至降低资源环境代价的前提下，使一亩农田一年种植粮食作物的产量提高到1.5吨以上。 2000年初到曲周时，当地粮食周年亩产徘徊在700公斤左右。当地农民长期采用"大水、大肥、浅旋"的 耕作方式，造成土壤盐碱化和板结，粮食增产难。 面对这种情况，我们从土壤—作物系统本身找答案。团队长期扎根田野一线，记录土壤养分供给和植物 养分吸收情况。为实现技术精准落地与光温资源高效利用，我们瞄准"苗齐、苗壮、苗匀"的目标，围 绕"土、肥、水、种、管"开展综合技术革新。 提升农业综合生产能力和质量效益。 ——摘自"十五五"规划建议 粮食安全是"国之大者"。如何在有限的耕地上实现粮食产量产能持续提升，进而实现资源高效利用与生 态环境保护双赢？这是我国推动农业现代化必须要面对的课题，也是我们科研团队长期以来攻坚的方 向。 经过持续试验与集成优化，我们逐步形成了"冬小麦—夏玉米周年'四密一稀'浅埋滴灌水肥药一体化绿 色生产技术"，并将种植模式、灌溉施肥与植保管理融为一体。该技术既大幅减少了灌溉用水，又实现 了养分的均衡供应，为提升产量和恢复 ...

Core Insights - The article highlights the achievements of the Quzhou Technology Courtyard team from China Agricultural University, which has significantly contributed to agricultural innovation and green development in Quzhou County, Hebei Province [2][3][4] Group 1: Team Achievements - The Quzhou Technology Courtyard team has developed and promoted 37 high-yield and efficient agricultural technologies over the past 16 years, increasing the adoption rate of these technologies from 17.9% to 53.5% between 2009 and 2014 [4] - The team was awarded the 2025 China Youth May Fourth Medal Collective, with 90% of its 122 members being under 35 years old, emphasizing the youth-driven approach to agricultural innovation [2][3] Group 2: Agricultural Practices - The team introduced the "Water-Nitrogen Postponement" technique, which reduced irrigation from four times to two, resulting in wheat yields exceeding 650 kg per mu, thus saving costs and improving productivity [3] - The "Green Ton Half Grain" initiative aims to achieve an annual yield of 1.5 tons per mu while reducing emissions by over 30%, with the 2024 demonstration bases already achieving a yield of 1.52 tons per mu, surpassing the county average by 42% [6] Group 3: Community Engagement - The Quzhou Technology Courtyard team engages closely with local farmers, providing hands-on training and support, which has led to the training of over 80,000 farmers and the cultivation of more than 1,000 "soil experts" and rural leaders [8] - The team has established 16 technology courtyards, allowing farmers to consult freely and receive immediate assistance, thereby bridging the gap between research and practical agricultural needs [3][5]
