| 摘 要： | 通过不同钙镁水平处理(正常、低钙、高钙、低镁、高镁)的水培试验,研究了钙、镁水平对烤烟钾吸收量、循环、外排和烟叶钾积累量的影响。结果表明,在本试验条件下,高钙和高镁处理可以促进烤烟根系对钾素的吸收,有效减少根系对钾营养的外排,增加钾的净吸收,同时能有效地调节钾素在烤烟体内的循环,并提高烤烟烟叶含钾量。在收获期,高钙处理的上、中、下部叶的钾含量比对照提高了0.38、0.41、0.69个百分点;高镁处理的分别比对照提高了0.31、0.42、0.60个百分点。本试验条件下,高钙、高镁处理可以提高根系钾的吸收,减少根系中钾的外排量,促进伤流液和韧皮部循环以及增加烟叶的钾积累量,最终提高上、中、下部叶的钾含量。
