氯是烤烟需要而又应限量的营养元素。烟叶含氯量过低,叶片吸湿力小,弹性差,易破碎,降低填充力;烟叶含氯量过高,燃烧性降低,香味变坏,安全性变差。据贵州烤烟质量普查报告,贵州烟叶的含氯量,一般在0.1%左右,氧化钾含量在1.6%左右,氯和钾的含量均低。因此,需要同时供给钾、氯,使其含量提高到适宜水平。考虑到贵州土地和气候条件的特点,如果用氯化钾部分代替硫酸钾,不仅可为烟株同时提供钾、氯,而且可以降低肥料成
Chlorine is a flue-cured tobacco needs and should limit the amount of nutrients. Tobacco leaf chlorine content is too low, leaf moisture absorption is small, poor flexibility, easy to break, reduce the filling force; Tobacco leaf chlorine content is too high, combustion decreased, the smell worse, the safety worsened. According to the Guizhou tobacco quality census report, Guizhou tobacco leaf chlorine content, generally about 0.1%, potassium oxide content of about 1.6%, chlorine and potassium content are low. Therefore, it is necessary to supply potassium and chlorine at the same time so as to raise the content to a suitable level. Taking into account the characteristics of land and climatic conditions in Guizhou, if potassium chloride is used instead of potassium sulfate, not only can potassium and chlorine be supplied to tobacco plants at the same time, but also fertilizer can be reduced
