当土壤经过干湿以后，土壤会发生明显的固定钾作用，土壤含钾量越高，固定钾能力越强。
The soil potassium fixation was increased after dry and humid alternation. Soil with higher potassium content had a higher fixation ability.
试验结果也表明，在生长中期土壤水分保持在60%，生长后期保持在80%的处理在获得了较高产量的同时也获得了较高的烟叶含钾量。
The experiments also indicated high leaf yields and potassium content in the treatment of soil moisture at the level of 60% in middle stage and 80% in latter stage respectively.
土壤水分和钾用量能提高叶片栅栏组织和海绵组织的含钾量。
Soil moisture and potassium amount could improve potassium content of palisade tissue and spongy tissue.
通过大田试验，研究了不同供钾方式对烟叶含钾量的影响及提高石灰性土壤上烤烟含钾量的可能途径。结果表明，施钾能显著提高烟叶产量，其中以粉肥结合喷优丰处理效果最好。
Field experiment was conducted to study the effect of different supplying styles of potassium fertilizer on potassium content in flue-cured tobacco leaves and the methods to increase the content.
