芝麻饼肥对烤烟根系生长发育的影响

Effect of the sesame cake to the flu-cured tobacco root system growth

以烤烟品种 K32 6为材料 ,在盆栽条件下研究了不同配比的芝麻饼肥对烤烟根系生长发育的影响。结果表明 ,腐熟饼肥配比的提高有利于增强根系活力 ,相应的提高了根中的烟碱含量 ;烟碱含量和根系活力在后期亦较高 ,根的总重也相应提高 ;同时 ,根冠比更协调。单施化肥 ,不利于根冠比的协调 ,根系活力微弱 ,但对后期烟碱的合成有一定的促进作用。各处理中以 T2 (饼肥用量占 2 0 % )

K326 act as the staff inch the flue-cared tobacco strain,its living to research below the grown in a pot term difference matches some bodily with somebody than sesame cake the person who develops the effect to the flue-cured totally loot system growth.Result shows:the cake becoming thorough my decomposed matins somebody with some body than the raise is favors of heightening the loot system vitality.The relevant raise nicotine content in the foot.Nicotine content and the root system vitality is living cater stage too tall over;At the same time The root cap contrasts and more harmonizes.Alone execute clerical fertilizer and does not benefit root cap ratio harmonization.The root system vitality is feeble.Yet possess is the specified action.Accelerating to the later stage nicotine compounding,The regulate the function of middle-wormer is appropriately with T2(the cake the amount to be used seizies20%)every share.
