摘　　要：通过盆栽试验,研究了喷施Mg+B、Mg、B、Mo、Ca对烤烟烟叶烟碱、总氮、多酚类、蛋白质和水溶性总糖含量的影响。结果表明:经Mg+B、Mg、B、Mo、Ca处理后,烟叶烟碱含量分别比对照下降了19.1%、15.1%、14.4%、20.9%、11.9%;总氮比对照下降了31.5%、26.9%、13.8%、40.0%、10.4%;蛋白质含量比对照也有所下降,Mo处理的效果最为明显,比对照降低了41.7%。Mg+B、Mg、B、Mo、Ca处理都不同程度降低了烟叶多酚类物质的含量,但降低幅度都不大,对水溶性总糖的积累均起促进作用。The effects of foliar spraying of Mg ＋ B, Mg, B, Mo, and Ca on pot cultured flue-cured tobacco were studied, and the nicotine, total nitrogen, polyphenols, proteins and water soluble sugars in tobacco leaves were determined. The results showed that comparing with the control, nicotine and total nitrogen in tobacco treated with Mg ＋ B, Mg, B, Mo, Ca decreased by 19.1% , 15.1% ,14.4% , 20.9% , 11.9% and 31.5% , 26.9% , 13.8% , 40.0% , 10.4% , respectively. Protein content decreased to a certain extent, particularly in Mo treatment which reduced by 41.7%. All treatments reduced polyphenols in different degrees, though not significantly, and promoted the accumulation of water soluble sugars in treated tobacco leaves.
