摘 要: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。Effects of an organism-mineral blended fertilizer on the yield and nutrient utilization rate of flue-cured tobacco were studied by pot experiments. The results were as following: Compared to common fertilizer with the same NPK amounts, the organism-mineral blended fertilizer specific for flue-cured tobacco could increase the nutrient utilization rates of N by 2.6%-4.5%, P by almost 2% in disposal AB, and BB, and K by 3.6% in disposal AA. The proportion of N, P, and K was also promoted and this enhanced the forming of tobacco leaves. The yields in disposal AA, AB, and BB were 8.52, 24.20, and 15.57% more; the proportions of middle leaves were 12.96, 12.10, and 11.98% more; the proportions of higher leaves were 14.69, 12.22 and 12.61% less compared with the control. Nicotine, total N, and protein were reduced and there were 7.36%-12.27% more K than in the control.
