| 摘 要： | 为探明不同施钾量对烤烟钾高效基因型新品系生长发育和含钾量的影响，本试验以‘K326’为对照，高钾新品系GK2、GK8为供试材料，分析比较烟株农艺性状、干物质积累量及含钾量在不同供钾水平下的差异。研究结果表明：增施钾肥可以明显改善烤烟高钾新品系的农艺性状，促进烟株株高、茎围、叶片大小及单株叶数的增加；团棵期不同供钾水平下烟株的长相长势基本一致，进入旺长期后，施钾240 kg/hm2时，烟株长势最好，不同品种（系）间表现为：GK8>GK2>‘K326’。烤烟高钾新品系根、茎、叶的干物质积累量随着施钾量的增加而增加，不同时期各器官干物质积累量为：叶>茎>根；不同供钾水平为：T3>T2>T1；不同品种（系）间表现为：GK8>GK2>‘K326’。
