摘要： 在大田条件下，研究了不同施硼措施对烤烟生长及产质量的影响，结果表明：与基施（P0）或不施硼肥（CK）处理相比，叶面喷施对促进烤烟生长，增加烟叶产量，提高烟叶质量有更显著的作用，且叶面整株喷硼（P4）的烟株其产值分别比基施硼肥，喷施上部叶（P1）、喷施中部叶（P2）、喷施下部叶处理（P3）高12.4%、56.1%、37.3%、48.1%。叶面喷硼处理对中部叶糖含量、钾含量以及烟碱含量的调控有积极的作用，整株叶面喷施硼肥处理的烟叶烟碱含量明显低于其他处理。

Abstract: A field experiment was conducted to study the effects of boron（B） application methods on the growth, leaf yield and quality of flue-cured tobacco, the results indicated that, compared to the treatments of applying boron(B) to tobacco plants basically or no B fertilizer application, the tobacco plants applied B by foliage dressing had higher growth potential, and produced much more tobacco leaf and better leaf quality. The tobacco plants foliar sprayed B whole plants gave much more output, and higher 12.4%、56.1%、37.3%、48.1% than that of foliar sprayed on the central leaves, upper leaves or lower leaves. Foliar spraying B promoted potassium uptake by plants, transforming from slowly available potassium to available potassium, and had a positive effects on adjusting and controlling the total sugar, potassium accumulation and nicotine in cutters.
