摘　　要：In order to provide reference for high quality tobacco producion,this experiment adopted a randomized block design in a field plot,and analyzed the effects of boron fertilizer on the growth,development on comprehensive quality of flue-cured tobacco by using mathematical statistics methods such as multiple comparison with NC297 as test material.The results showed that:spraying boron fertilizer on flue-cured tobacco leaves can promote the growth of flue-cured tobacco NC297 to a certain extent,effectively reduce the total particulate matter and tar content of tobacco,and play a positive role in regulating the total sugar,reducing sugar,nicotine and potassium content of flue-cured tobacco;the comprehensive quality of NC297 was the best when boron was applied at medium potassium level(K2B1).以NC297为试验材料,采用大田小区随机区组设计,运用多重比较等数理统计方法分析不同供钾水平下硼肥对烤烟生长发育和综合品质的影响,以期为优质烟叶的生产提供参考。结果表明:烤烟叶面喷施硼肥,能在一定程度上促进烤烟NC297的生长,能有效降低烟支的总粒相物和焦油含量,对烤烟总糖、还原糖、烟碱和钾元素含量有积极调控作用;中钾水平施硼处理(K2B1),NC297综合品质最优。
