| 摘 要： | 为了筛选钾高效品种，在盆栽条件下，研究了黄淮麦区当年广泛种植的28个小麦品种在两个钾素水平下的干物质积累、钾素积累、钾素利用方面的差异。结果表明，不同小麦品种的耐低钾能力不同，淮阴9628、济南17、798、郑州9023、龙丰1号、龙丰2号等6个品种，钾利用效率高，具有低钾下产量性状良好、钾积累能力强、钾利用指数高等特点；不同小麦品种对钾肥的响应程度不同，西安8号、豫西832、偃师16为施钾肥敏感小麦品种，具有低钾下产量水平低、施钾后产量提高幅度大等特点。 |
| 关 键 词： | 黄淮麦区 小麦 品种 钾利用指数 钾肥 吸钾量 |

| Abstract: | By pot cultivation, this experiment was conducted to study the K efficiency among 28 wheat varieties under two K levels in Huang-huai wheat growing region. The results showed that there were great differences among wheat varieties in the K use ability, and Huaiyin 9628, Jinan 17, 798, Zhengzhou 9023, Longfeng 1 and Longfeng 2 were possessed of high K utilization efficiency, which had the characteristics of higher yield in low K level, stronger K absorption ability, and higher K utilization index; Xi'an 8, Yuxi 832 and Yanshi 16 were K fertilizer sensitive wheat varieties, which had the features of lower yield in low K level and relatively bigger increments after the application of K fertilizer. |
| Keywords: | Winter wheat Variety 5 K accumulation amount K utilization index |
