在大田生产条件下 ,采用单株挂牌设置处理的研究方法 ,研究了强化施钾、打顶抹杈以及喷施生长素等化学、生理调控措施对烤烟钾吸收及其在库源中再分配的影响。结果表明 ,打顶后根际集中补施K2 SO4 和KNO3 可以提高腰叶及其以上叶片含钾量 ,而补施KCl主要提高脚叶及下二棚叶片含钾量 ,现蕾后不打顶或打顶结合生长素处理茎断面有利于不同部位叶片含钾量的提高 Under the conditions of field production, the methods of setting up single plant were used to study the effects of chemical and physiological control measures such as potassium fertilizers application, top wiping and spraying auxin on the potassium absorption of flue-cured tobacco and its redistribution influences. The results showed that K2 SO4 and KNO3 could significantly increase the potassium content of the leaves above and below the leaf after the topping, while the KCl supplementation mainly increased the potassium content of the leaves of the leaves and the leaves of the second plant after the topping, Or topping combined with auxin treatment stem section is conducive to different parts of the leaf potassium content increased
