【摘要】 新疆南疆地区种植的紫花苜蓿因苗期生长缓慢、受风沙影响成活率低，普遍采用小麦保护紫花苜蓿播种的方式。为探索一种资源利用率高、经济效益好且适合当地推广发展的最优种植模式，本研究以新疆南疆地区紫花苜蓿主要种植模式为切入点，选择当地常见的紫花苜蓿5种种植模式，研究了不同种植模式下紫花苜蓿干物质产量、营养价值及经济效益。结果表明：在2020年播种青贮玉米，2021年实施春小麦套种紫花苜蓿的种植模式(M5)在紫花苜蓿干物质总产量、粗蛋白含量以及经济效益方面的增益效果更为明显，适合当地推广种植。更多还原

【Abstract】 The alfalfa planted in the southern Xinjiang region has a slow growth rate at the seedling stage and a low survival rate due to the influence of wind and sand.The wheat-protected alfalfa seeding method is generally adopted.In order to explore an optimal planting mode with high resource utilization rate, good economic benefits and suitable for local promotion and development, this study took the main planting modes of alfalfa in southern Xinjiang as the starting point, and selected five common local alfalfa planting modes.The dry matter yield, nutritional value and economic benefit of alfalfa under different planting modes were studied.The results show: Sowing silage corn in 2020 and implementing spring wheat interplanting alfalfa planting mode(M5) in 2021 has more obvious gains in terms of total dry matter yield, crude protein content and economic benefits of alfalfa, which is suitable for local promotion.更多还原
