摘要
田间小区试验研究了贫氯土壤增施氯肥对烤烟产质量的影响。结果表明,在一定范围内增加适量的氯肥可提高烟叶中氯素、钾素和还原糖含量,促进干物质的有效累积,降低烟叶中烟碱含量,烟叶化学成分趋于协调。同时,增施氯肥的处理烟株农艺性状、经济性状和内在化学品质均优于对照,其中增施氯22.5kg/hm2效果最佳,烟叶产量增幅最大、外观质量最好,增施18.75和26.25kg/hm2氯的效果次之。
The effects of applying chlorine fertilizer to the soil with deficiency of chlorine on yield and quality of fluecured tobacco were studied through field experiments.The result showed that proper application of chlorine fertilizer can increase contents of chlorine,potassium and reducing sugars in tobacco leaf,enhance the effective accumulation of dry matter and reduce the nicotine content in tobacco leaf;the chemical constituents in tobacco leaf tend to be harmonious.Meanwhile,the agronomic characters of tobacco plant that applied with chlorine fertilizer was superior to Ck,in which the effect of treatment applied KCl of 22.5 kg/hm2 was the best（the increase amplitude of tobacco yield and appearance quality were the best）,the effects of treatment applied KCl of 18.75 kg/hm2 and 26.25 kg/hm2 were the next.
