| 摘 要： | 在砂培条件下，对47个棉花品种进行了钾高效基因型品种筛选研究。结果表明，不同棉花品种的耐低钾能力不同，其中602、新陆早6、角棉、18 3、新海13号等品种的钾利用效率较高，具有低钾条件下钾积累能力强、钾利用指数高等特点；石K7、新陆早10号、新海14号为钾低效基因型品种，具有低钾下干物质积累较少、吸钾能力相对较弱等特点。

| Abstract: | River sand pot experiment was conducted to study screening of the potassium high efficiency among 47 cotton varieties. The result indicated that there were great difference among cotton varieties in the low potassium ability, cutivars 602, Xinluzao 6, Xinluzhong 15, Xinhai 16, JiaoMian, 18 3, and Xinhai 13 had higher K utilization efficiency, stronger K absorption ability, and higher K utilization index in low K level; while cutivars ShiK 7, Xinluzao 10 and Xinhai 14 had lower K efficiency , fewer K absorption ability and lower K utilization index in low K level. |
