摘要: 为深入了解黔西南州烤烟氯含量状况,研究了该地区烟叶氯含量分布特征及影响因素。结果表明:黔西南州烤烟氯含量的变化范围为0.24%~0.43%,平均值为0.30%,含量适宜;贞丰县烤烟氯含量极显著高于其他各县;烤烟氯含量空间分布有从东北部向西南部递减的分布趋势。‘兴烟1号’品种的氯含量显著高于‘K326’;烤烟氯含量有随着土壤粘粒含量和土壤有机质含量升高而增加的趋势;当土壤pH在5.2~6.8范围内时,随植烟土壤pH升高,烟叶氯含量有升高的趋势;土壤pH在6.8~7.5或5.2以下时,随植烟土壤pH升高,烟叶氯含量有降低的趋势。

Abstract: The distribution of chlorine contents of flue-cured tobacco and its influencing factors were analyzed in order to understand their characteristics in Qianxinan. The results showed that the range of variation of chlorine content in the flue-cured tobacco leaf was 0.24%-0.43%, the mean content was 0.30% and belonged to good-chlorine tobacco-planting areas. The chlorine content of flue-cured tobacco in Zhenfeng Country was significantly higher than that of other counties. The spatial distribution of chlorine content had a tendency of decreasing gradually from the northeast to southwest. The chlorine content of‘Xingyan1’was significantly higher than that of‘K326’. The chlorine content in flue-cured tobacco had an increasing trend along with increasing of soil clay content and soil organic matter content. When soil pH was 5.2-6.8, along with soil pH rising, the chlorine content in flue-cured tobacco had an increasing trend; when soil pH was 6.8-7.5 or below 5.2, along with soil pH rising, the chlorine content in flue-cured tobacco had a falling trend.
