奏响新时代“黄河大合唱”的草牧乐章——来自沿黄省份的一线调研

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].
