Group 1 - The "International Conference on Grassland and Grass Industry 2025" was held in Hohhot from July 10 to 13, focusing on the theme "Three Lives Integration, Technology Empowerment" [1] - Over 400 experts and scholars from institutions such as the Chinese Academy of Sciences and various international countries participated, aiming to explore trends in grass science and provide strategic consulting for government and industry development [1] - The conference included an inspection of the collaborative project between Hohhot Agricultural Group and the Chinese Academy of Sciences, which has achieved innovative technological results in grass and livestock industries [1] Group 2 - Inner Mongolia has 1.32 billion acres of natural grassland, accounting for 22% of China's total grassland area, and is a crucial part of the Eurasian grassland [2] - The region has implemented strict ecological protection measures and policies, leading to a stable vegetation coverage of around 45% and improved ecological conditions [2] - Hohhot is recognized as an important ecological barrier for Northeast and North China, with diverse grassland vegetation and unique culture providing a natural experimental field for ecological research and grass industry development [2]

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].
