内蒙古拥有13.2亿亩天然草原，占中国草原总面积的22%，是欧亚大陆草原的重要组成部分。记者 了解到，我区多年来深入践行"绿水青山就是金山银山"的理念，实施最严格的草原生态保护制度，持续 推进草原生态保护补助奖励政策，落实草畜平衡和禁牧休牧轮牧制度，有效遏制了草原退化沙化趋势。 全区草原综合植被盖度连续多年稳定在45%左右，重点生态功能区草原生态环境持续改善，广袤的草原 重新焕发出勃勃生机。 与会专家表示，呼伦贝尔不仅是欧亚大陆草原带的重要组成部分，更是维系东北、华北地区生态安 全的重要屏障。其丰富的草原植被类型、多样的生物物种和独特的草原文化，为草原生态研究与草业发 展提供了天然的试验场。近年来，呼伦贝尔探索"草原生态旅游+特色草产品开发"模式，积极在退化草 原修复、草畜平衡管理、碳汇交易试点等领域开展创新实践，给出了全球草原可持续发展的"中国答 案"。 本次大会由中国植物学会、中国草学会联合中国科学院植物研究所、饲草种质高效设计与利用全国 重点实验室、兰州大学、中国农业大学共同主办，呼伦贝尔农垦集团、内蒙古农牧业科学院等承办。 以"三生融合 科技助力"为主题的"国际草原与草业大会2025"，7月10日至1 ...

Core Viewpoint - The article emphasizes the importance of promoting a comprehensive green transformation in development and enhancing the quality of the Yellow River Basin's ecological and agricultural systems, particularly through the advancement of grass and livestock industries [1]. Group 1: Grass and Livestock Industry Development - The Ministry of Agriculture and Rural Affairs has launched a three-year project for high-quality development of grass and livestock in the Yellow River Basin, aiming to balance ecological protection with production [1]. - In Qinghai, the mixed planting of forage oats and peas has improved the efficiency of grass production, with fresh grass yield per mu reaching 3.6 tons, a 12% increase compared to previous monoculture practices [2][3]. - The protein content of mixed forage can reach 13%, nearly a 50% increase compared to single-crop oats, leading to reduced reliance on concentrated feed and shortening the fattening period for cattle by 10-15 days [3][4]. Group 2: Technological Innovations in Forage Production - The introduction of membrane hole sowing technology in Gansu has increased seedling emergence rates by 18% and survival rates by 15%, significantly improving the economic viability of forage production [6]. - The use of acid fertilizers instead of alkaline ones in saline-alkali soils has enhanced the effectiveness of fertilization by over 20%, contributing to the successful cultivation of high-quality alfalfa [8]. Group 3: Ecological and Economic Benefits - The implementation of mixed planting and advanced cultivation techniques has led to a 20% reduction in soil erosion rates and improved vegetation coverage in regions like Gansu [6]. - In Henan, the rotation of alfalfa with grain crops has improved soil fertility, with pH levels decreasing from 8.6 to 8.2 and salt content dropping from 0.3% to 0.2%, resulting in increased crop yields [9].

Core Viewpoint - The article highlights the dedication and contributions of Yu Chengqun, a prominent figure in the field of grassland science in Tibet, who has significantly advanced the cultivation and management of high-quality forage species to support local pastoral communities [1][2][4]. Group 1: Contributions to Forage Cultivation - Yu Chengqun has successfully bred five excellent forage varieties and developed eight high-yield planting technology standards for Tibet's main forage crops, significantly benefiting local farmers [2][4]. - Under his guidance, over 100,000 acres of forage have been planted, leading to an increase in annual income of more than 3,000 yuan per household for nearly 10,000 pastoral families [3][4]. Group 2: Technological Innovations - The research team has developed 25 technical specifications for the industrialization of high-quality forage suitable for Tibet's unique climate, addressing key technological bottlenecks in grassland agriculture [4]. - Yu Chengqun's work includes extensive field research across all 74 counties in Tibet, accumulating over one million kilometers in travel to implement successful forage cultivation projects [4]. Group 3: Community Engagement and Impact - Yu Chengqun maintains active communication with local farmers, providing ongoing support and guidance to ensure the success of forage cultivation efforts [3]. - His commitment to improving the ecological safety and agricultural development of Tibet is evident in his hands-on approach, emphasizing the importance of practical application of scientific research in the field [3][4].
