（走进中国乡村）辽宁彰武“麦豆轮作”：麦浪固沙 豆香富农

Core Viewpoint - The article highlights the successful implementation of a "wheat-soybean rotation" model in Zhangwu County, Liaoning Province, which not only combats land desertification but also increases farmers' income through double cropping [1][2]. Group 1: Agricultural Practices - Zhangwu County has initiated a "wheat-soybean rotation" model starting in 2023, allowing for two harvests in one year, which effectively reduces wind erosion and enhances soil protection [1]. - The rotation model involves precise timing, with spring wheat sowing advanced to early March, allowing seedlings to protect the soil during peak wind periods in April [1]. - After harvesting wheat in July, soybeans are immediately planted, benefiting from nitrogen-fixing bacteria and providing a protective barrier for the soil [1]. Group 2: Soil Improvement - The soil quality in Zhangwu County has improved, with organic matter content increasing from 0.8% to 1% in most areas, and some regions reaching 1.2% [2]. - The promotion of this agricultural technique is set to expand to 500 acres in five townships in 2024, and to 11,000 acres in 12 townships by 2025, demonstrating significant ecological and economic benefits [2]. Group 3: Economic Impact - The economic benefits of the "wheat-soybean rotation" are notable, with an average profit of over 800 RMB per mu from planting wheat and local black soybeans [2]. - The successful trial of 500 acres of fresh soybeans this year has led to plans for expanding the planting area in the following year [2]. Group 4: Environmental Strategy - The rotation model contributes to food security while establishing a robust ecological barrier, providing a new approach for desertification control in northern sandy regions [3].
