摘要 本文就宝鸡烟区烟草专用肥不同肥料基追比对烤烟生长发育和品质的影响进行了研究。结果表明,不同肥料基追比对植株后期田间发育没有显著性影响,不同处理间成熟期农艺性状没有显著性差异;不同肥料基追比可在一定程度上影响中部烟叶总糖和还原糖含量。通过对烟叶化学成分进行赋值计算,适度降低宝鸡烟区肥料基追比可以提高中部烟叶和上部烟叶化学成分的协调性,但基追比最低不宜低于5∶5。 Effects of different base topdressing ratios of tobacco special fertilizer on growth and quality of flue-cured tobacco in Baoji wereevaluated.The results showed that different fertilizer base topdressing ratios had no significant effect on field development in the later stage of plantgrowth.There was no significant difference in agronomic characters among different treatments.The contents of total sugar and reducing sugar in middletobacco leaves were affected by different fertilizer base topdressing ratios to a certain extent.By assignment calculation of chemical composition oftobacco leaves,moderate reduction of fertilizer base topdressing ratio in Baoji tobacco growing area could improve the chemical composition of tobaccomiddle leaves and upper leaves,but the lowest base catch ratio should not be lower than 5:5.
