【摘要】 通过对我省10年种烟土壤与烟叶含钾量的分析，及烤烟钾肥施用技术研究表明：种烟土壤速效钾含量较高，而烟叶含钾量偏低；单纯提高基把中钾的用量，达不到提高烟叶含钾量的目的。而在烤烟吸收钾高峰期前，采用根外追肥的方法，烟叶含钾量明显增加。更多还原

【Abstract】 Based on the 10 years Potassium analysis of tobacco Soil and tobaclo leaf in Heilongjiang province.The paper reports the study on the application andeffect of potash fertilizer. It showed that the contentof rapid release K in Henlong Jiang tobacco soil isvery high; but the potassium content in the to baccoleaf is low; The K content in the tobacco leaf cannot in crease to the standard level only by raise thecontent of potassium in the basal fertilizer. The experiment confirmed that the patassium content inthe tobacco leaf will increase significalltly by applythe potash fertilizer on the leaf before the coming ofwhich to bacco plant absorb potassium.更多还原
