采用调查研究和田间试验对保山市烟叶氯含量状况进行了分析研究;根据调查分析结果,进行了不同施氯量的田间试验。结果表明:保山烟叶含氯量很低,平均为0.12%,变幅为0.01%~0.97%,有91.08%的烟叶样本含氯量低于优质烟叶要求的含氯下限(0.3%),缺氯的烤烟样品占8.91%。烟叶含氯量低已成为影响保山烟叶质量的因素之一;在该地区氯含量较低的土壤上,施用氯肥不仅可以提高烟叶的产量、产值、上中等烟比例、均价,而且还可改善烟叶的外观质量和内在品质,主要表现为使烟叶颜色加深、色度增强、油分增加,烟叶中氯、钾、糖含量也随施氯量的增加而增加。
Investigation and field experiments were carried out to analyze the chlorine content of tobacco leaves in Baoshan City. According to the results of investigation and analysis, field experiments with different application rates of chlorine were conducted. The results showed that the content of chlorine in Baoshan tobacco was very low with an average of 0.12% and the range of 0.01% -0.97%. The content of chlorine in 91.08% of the tobacco samples was lower than the minimum (0.3%), Of the flue-cured tobacco samples accounted for 8.91%. Tobacco leaf chlorosis has become one of the factors that affect the quality of Baoshan tobacco; in the lower chlorine content of the soil in the region, the application of chlorine fertilizer can not only increase the yield of tobacco leaves, output value, upper middle-grade tobacco, the average price, but also The appearance quality and internal quality of tobacco leaves were improved. The main features of tobacco leaves were darker color, stronger chroma and higher oil content. The content of chlorine, potassium and sugar in tobacco also increased with the increase of chlorine application rate.
