Oats ( L.) are forage grasses moderately tolerant to saline-alkali soil and are widely used for the improvement and utilization of saline-alkali land. Using the oat varieties collected from the Qaidam Basin as experimental materials, based on the analysis data of the main agronomic traits, quality, and soil physical and chemical properties of different oat varieties at the harvest stage. The hay yield of Molasses (17,933.33 kg·hm) was the highest ( < 0.05), the plant height (113.59 cm) and crude fat (3.02%) of Qinghai 444 were the highest ( < 0.05), the fresh-dry ratio (2.62), crude protein (7.43%), and total salt content in plants (68.33 g·kg) of Qingtian No. 1 were the highest ( < 0.05), and the Relative forage value (RFV) of Baler (122.96) was the highest ( < 0.05). In the 0-15 cm and 15-30 cm soil layers of different oat varieties, the contents of pH, EC, total salt, Ca, Mg, and HCO showed a decreasing trend at the harvest stage compared to the seedling stage, while the contents of organic matter, total nitrogen, Cl, and SO4 showed an increasing trend. The contents of K and Na maintained a relatively balanced relationship between the seedling stage and the harvest stage in the two soil layers. Qingtian No. 1, Qingyin No. 1, and Molasses all rank among the top three in terms of production performance and soil physical and chemical properties, and they are the oat varieties suitable for cultivation in the research area.
燕麦（L.）是对盐碱土耐受性中等的饲草，被广泛用于盐碱地的改良和利用。以采自柴达木盆地的燕麦品种为试验材料，基于不同燕麦品种在收获期的主要农艺性状、品质及土壤理化性质的分析数据。糖蜜燕麦的干草产量（17,933.33 kg·hm）最高（<0.05），青海444的株高（113.59 cm）和粗脂肪（3.02%）最高（<0.05），青甜1号的鲜干比（2.62）、粗蛋白（7.43%）和植株总盐含量（68.33 g·kg）最高（<0.05），巴勒燕麦的相对饲用价值（RFV）（122.96）最高（<0.05）。在不同燕麦品种0-15 cm和15-30 cm土层中，与苗期相比，收获期土壤pH、电导率、总盐、钙、镁和碳酸氢根含量呈下降趋势，而有机质、全氮、氯离子和硫酸根含量呈上升趋势。两个土层中钾和钠的含量在苗期和收获期保持相对平衡的关系。青甜1号、青引1号和糖蜜燕麦在生产性能和土壤理化性质方面均位列前三，是研究区域适合种植的燕麦品种。
