广东烟区烤烟钾氯硫元素含量的变异分析

分析了广东不同产区、不同等级、不同品种、不同年份烤烟样品中钾、氯、硫含量及变异特点.结果表明:广东烤烟平均钾含量((2.29±0.33)%)、硫含量((0.46士0.10)%)、钾氯比(11.33±5.68)适宜;氯含量(0.26±0.13)%)略低,氯含量的变异系数(51.16%)最大,钾含量的变异系数(14.26%...

Variance analysis on contents of potassium, chlorine and sulfur of flue-cured tobacco leaves in Guangdong tobacco-growing areas

The contents and variation characteristics of potassium,chlorine and sulfur of flue-cured tobacco leaves collected in Guangdong tobacco-growing areas from different production areas,different tobacco gradings,different tobacco cultivars and different years were analyzed.The results indicated that the contents of potassium,sulfur and the ratio of potassium to chlorine were medium with the mean of(2.29±0.33) %,(0.46±0.10) % and(11.33±5.68),respectively,and chlorine content was lower with the mean of(0.26±0.13) %.The variation coefficient(51.16 %) of chlorine content was the highest,the variation coefficient(14.26 %) of potassium content was the lowest.Extremely significant differences of the contents of potassium,chlorine and the ratio of potassium to chlorine of flue-cured tobacco were found among the different production areas.Extremely significant differences of potassium content of flue-cured tobacco were found among the different gradings.The differences of content of potassium,chlorine,sulfur and the ratio of potassium to chlorine of flue-cured tobacco leaves didn't reach to the significant level among different cultivars and different years.
