有机肥与化肥配施对烤烟生长发育的影响

Effect of Combining Application of Organic and Chemical Fertilizers on the Growth and Development of Flue-cured Tobacco

摘要: 通过盆栽试验和田间试验,研究了不同种类有机肥与化肥配施对烤烟生长发育、抗病性、及营养代谢的影响,结果表明:当有机氮肥施用比例占总施氮量的25%时,有利于烤烟根系生长,使烟株生长健壮,提高抗病力,并能协调烟叶中氮磷钾营养的分配比例,提高上部烟叶钾的含量,有利于提高烟叶品质。

Abstract: The pot and field experiments were conducted to study the effect of combining application of different organic and chemical fertilizers on the growth and development of flue-cured tobacco.The results showed that as the amount of organic-N fertilizer applied was 25% of total N levels, tobacco plants grew better, the disease resistance was increased, the concentrations of potassium in upper leaves was also improved.Thus, combining application of organic and chemical fertilizers could improve the quality of flue-cured tobacco.
