摘要
选取市场上常见的六种烟草专用复合肥,在相同的施肥量、相同的管理方式下比较其对烤烟植物学性状、产量以及烟叶氮、磷、钾含量的影响。结果表明,施用复合肥的处理均能增加烤烟的株高、茎围、最大叶长和最大叶宽,不同程度地提高烟叶产量和外观品质;施用复合肥处理可以明显降低烟叶中氮的含量,显著提高磷、钾的含量;施用复合肥的处理之间效果差别不明显。
In this research, six kinds of special fertilizer for tobacco which were selected from the common market were adopted to study their effects on the botanical character, the yield as well as the content of N, P and K in the tobacco under the same amount of fertilizer and the same management. The results were as follows： special fertilizer for tobacco could benefit its agricultural properties and improve its yield and quality, but the difference among each fertilizer treatments was not significant and application of special fertilizer decreased the amount of N while increased the amount of P and K in the tobacco,
