    摘要:

    为了解抚仙湖流域植烟土壤的烟叶综合质量,对流域内4种类型土壤(水稻土、沙壤土、红壤土、紫色土)及其烤后烟叶样品进行检测分析和评价。土壤检测结果显示:4种植烟土壤pH值为6.16~6.73;有效磷和速效钾含量较高,分别为19.03~64.48 mg/kg和111.09~397.89 mg/kg;水稻土的碱解氮含量118.02 mg/kg,较适宜,其他土壤的整体偏低,在51.68~59.66 mg/kg;沙壤土有机质含量仅4.14 g/kg,其他3种土壤有机质含量较适宜,为17.44~21.06 g/kg。红壤土烟叶外观质量得分最高,上、中、下3部位烟叶得分分别为81.25、83.50和74.75。沙壤土得分最低;4种土壤烟叶化学成分均符合优质烟叶要求,化学成分协调性较好;红壤土烟叶感官质量评吸结果得分最高,上、中、下部烟叶得分分别为83、84和81,沙壤土得分最低,上、中、下部烟叶得分分别为80.0、81.0和77.5。通过比较,红壤土烟叶初烤后综合质量最好,沙壤土的最差。

    Abstract:

    In order to study the comprehensive qualities of flue-cured tobacco from 4 soil types(paddy soil, sandy loam, red loam and purple soil) in Fuxian Lake basin, soil samples and tobacco leaves were tested, analyzed and evaluated. The results showed that pH values of 4 different soil types were 6.16-6.73 and the contents of available phosphorus and available potassium were high, which were 19.03-64.48 mg/kg and 111.09-397.89 mg/kg respectively. The content of alkaline hydrolytic nitrogen of paddy soil was 118.02 mg/kg, which was suitable. The content of alkaline hydrolytic nitrogen of the other 3 soil types were 51.68-59.66 mg/kg, which were low. The content of organic matter of sandy loam soil was 4.14 g/kg, which was low. The content of organic matter of the other 3 soil types were 17.44-21.06 g/kg, which were suitable. The appearance quality of tobacco leaves in red loam was the best in all soil types. The appearance quality of tobacco leaves in red loam was the best in all soil types, the scores of upper, middle and lower tobacco leaves were 81.25, 83.5 and 74.75 respectively; and scores of that in sandy loam were the lowest. Chemical components of tobacco leaves in 4 soil types all accorded with the standard range of high-quality tobacco leaves, and coordination of chemical components of tobacco leaves in all soil types were good. Sensory evaluation of tobacco leaves in red loam was the best in all soil types, the scores of sensory evaluation of upper, middle and lower tobacco leaves were 83, 84 and 81 respectively, and scores of that in sandy loam were the lowest, which were 80.0, 81.0 and 77.5 respectively, for upper, middle and lower tobacco leaves. Comprehensive quality of flue-cured tobacco in red loam is the best, followed by that in purple soil and in paddy soil, and in sandy loam is the worst.
