摘  要：
为探明干旱胁迫下不同种类钾肥配施对烤烟钾素含量的影响,通过盆栽试验研究了干旱胁迫下枸溶性钾肥配施对烤烟农艺性状、干物质积累和钾素含量的影响。结果表明:不同供水水平下配施一定比例的枸溶性钾肥均能促进烤烟生长,增加烤烟生物量;正常供水下枸溶性钾肥配施与硫酸钾复合肥单施相比可显著增加烟叶和烟株含钾量,干旱胁迫下其对烤烟钾素营养效果与单施硫酸钾复合肥相似。前期水分正常、后期干旱条件下,枸溶性钾肥配施可替代硫酸钾复合肥单施,以50%枸溶性钾+50%水溶性钾施肥处理效果较好。

摘  要：
In order to explore the effects of the combined application of different types of potash on the potassium content of flue-cured tobacco under drought stress,through pot experiment the authors studied the effects of combined application of citrate soluble potash on agronomic traits,dry matter accumulation,potassium content of flue-cured tobacco under drought stress.Results:Combined application of a certain proportion of citrate soluble potassium could promote the growth of flue-cured tobacco,increase biomass under different water levels.Under normal water supply conditions,compared with the treatment which applied potassium sulfate compound fertilizer,the combined application of citrate soluble potash could significantly increase potassium content of leaf and plant.Under drought stress conditions,the effects of these fertilizer treatments on potassium nutrition of flue-cured tobacco was similar with potassium sulfate compound fertilizer.The combined application of citrate soluble potash could replace the application of potassium sulfate compound fertilizer solely under the condition of sufficient water in prophase then drought stress and the treatment of 75%citrate soluble potassium +25% water soluble potassium had the better effects.
