摘要: 采用盆栽试验研究了褐土区不同钾肥施用量对烤烟生长过程中几种酶活性的影响.结果表明,施用钾肥提高了烟株的硝酸还原酶(NR)活性和根系活力,增强了烟株生长前期叶片合成叶绿素的能力;钾素对超氧化物歧化酶(SOD)活性具有调节作用,在烟株生长的前期和中期有提高SOD活性的能力;栽后75 d,烟株的蔗糖酶活性小于栽后60 d的,施用钾肥对蔗糖酶活性有一定的提高,但是钾肥的不同用量处理间差别不大;在烤烟生长中后期,随着烟株的生长发育,根系ATP酶活性是降低的,施用钾肥提高了根系ATP酶活性.

Abstract: Experiments in pot were carried out to study the effect of different potassium application rate on some enzymes activity during the course of the growth of Flue-cured tobacco in Cinnamon soil area. The NR ac-tivity and root activity are enhanced and the leaf ability of composing chlorophyll during the prophase of the growing process is increasing by using potassium fertilizer. Potassium can adjust the SOD activity and increase the SOD activity during the prophase and metaphase of the growing process. The invertase activity of 75 days after transplanting is lower than that of 60 days after transplanting. The invertase activity is increased by using potassium fertilizer, but the difference among the different potassium application rate treatments is small. Dur-ing the metaphase and anaphase of the growing process the ATPase activity of root is added by using potassium fertilizer, but the ATPase activity of root is reduced along with the growing of the plant.

Key words: Cinnamon soil, Potassium, Flue-cured tobacco, Enzyme
