增施不同生物钾肥对烤烟生长发育及烟叶品质的影响

试验以云烟100为材料,研究了增施不同生物活性钾肥对烤烟农艺特性、经济性状、常规化学成分和感官质量等的影响。结果表明:增施不同生物活性钾肥处理对烤后烟叶的产质量和烟叶钾含量均有一定影响,其中喷施叶面生物活性钾肥B 500 g/667m~2的处理烤烟均价、产量、产值分别为29.85元/kg、128.60 kg/667m~2和3838.71元/667m~2,中上等烟比例为95.20%;同时,该处理烟叶的内在化学成分协调,钾离子含量明显增高,烟叶抽吸品质较好,工业可用性提高。

Effects of Increase Different Biotic-potassium Fertilize Application on Development and Quality of Flue-cured Tobacco Leaves

Taking Yunyan 100 as material, the ifeld experiment was conducted to study the effect of increase different biotic-potassium fertilized application on botanical character, economic character, and chemical component sand sensory quality of flue-cured tobacco leaves. The results showed that increasing different biological potash application inlfuenced roast tobacco leaf production, quality and potassium content. Spraying on the leaf of biological activity of potash 7 500 g/hm2 B, average acres of lfue-cured tobacco, yield and output value reached 29.85 yuan (RMB)/kg, 1 929kg/hm2 and 57 580.65 yuan(RMB)/hm2, the proportion of superior tobacco reached 95.20%. At the same time, tobacco intrinsic chemical composition had better coordination, potassium content increased obviously, the sensory evaluation of suction quality became better, and industrial availability increased.
