摘要
在云南 4个烟区对 3个烤烟品种进行了大田各生育时期钾在烟株中的积累和分配的研究。结果表明 ,烤烟成熟期钾素积累缓慢或下降 ,烟叶含钾量降低 ,是云南烤烟含钾量低的关键 ,钾在烟株中分配不够合理也是云南烤烟的低钾原因之一 ,这种不合理分配在品种间存在着明显的差异。
The potassium accumulation and distribution in tobacco plant during different growth stages in four soil types and three flue\|cured tobacco varieties were studied. The results showed that the main reason of low potassium content in Yunan tobacco were slowness or decrease of potassium accumulation during maturing stage and unreasonableness of potassium distribution in tobacco plant, which was related to the varieties.\;
