利用盆栽试验研究了有机-无机专用混配肥对烤烟产量和养分利用的影响。结果表明,与施等NPK养分的普通专用肥相比较,施用有机-无机烟草专用混配肥AB、BB处理的氮肥利用率提高2.6%～4.5%,磷肥利用率提高近2%,处理AA钾肥利用率提高3.6%,增加烟叶中氮、磷和钾的分配比例,有利于烟叶产量的形成,提高烟叶可利用程度,处理AA、AB和BB增产8.52%、24.20%、15.57%,中部烟叶所占比例提高12.96%、12.10%和11.98%,上部烟叶所占比例下降14.69%、12.22%、12.61%;烟碱、总氮、蛋白质含量有所下降,钾含量提高7.36%～12.27%,烟叶施木克值、糖碱比更趋于协调。
Pot experiments were conducted to study the effects of organic-inorganic mixed fertilizers on yield and nutrient utilization of flue-cured tobacco. The results showed that compared with the conventional special NPK fertilizers, the nitrogen use efficiency of organic-inorganic tobacco mixed fertilizers AB and BB increased by 2.6% -4.5% and the phosphorus utilization rate increased by nearly 2% The utilization rate increased by 3.6%, increased the distribution proportion of nitrogen, phosphorus and potassium in tobacco leaves, which was in favor of the formation of tobacco leaf yield and the availability of tobacco leaf. The yield of AA, AB and BB increased 8.52%, 24.20% and 15.57% The proportions increased by 12.96%, 12.10% and 11.98% respectively. The proportions of upper leaves decreased by 14.69%, 12.22% and 12.61% respectively. The content of nicotine, total nitrogen and protein decreased while the content of potassium increased by 7.36% ~ 12.27% Muck value, more than sugar and alkali coordination.
