云南陆良地区6个主栽烤烟品种适宜性分析

摘要

对云南陆良地区6个主栽烤烟品种烟叶的物理特性、化学成分进行了采样调查，共计收集241个 C3F 烟叶样品。结果表明，NC102与红花大金元两个品种的综合表现良好，烤后烟叶外观物理特性突出，内在化学成分协调，各指标均在优质范围内，工业可用性较高，适宜在陆良地区种植。K326含梗率、双糖差及淀粉含量偏高，叶片密度偏低；云烟87含梗率、淀粉及总氮含量偏高，双糖及烟碱含量偏低；二者内在化学成分不协调，工业可用性较低，不适宜在陆良区域种植。NC297、云烟97两个品种在陆良烟区种植适宜性有待进一步分析验证。%In order to study the suitability of dieffrent flue-cured tobacco varieties in Luliang, Y unnan, 241 flue-cured tobacco m iddle leaves ofgrade C 3F about6 diefferntvarieties w ere collected and analyzed in 2010.R esults indicated that “N C 102” and “H ongda” had good synthetical character: leaf appearance and physical porperties w ere outstanding, intrinsic chym ic com position w as in harm onious proportions, allthe indicators w ere in properrange ofhigh quality flue-cured tobacco and fitted forindustrially utilizing, both w ere suitable forplanting in Luliang.The difference oftotalsugarand reducing sugar, stalk and starch contentof “K 326” w as on the highside and the density of leaf w as low .The stalk , starch and nitrogen contentof “Y unyan87” w as on the highside, w hile the totalsugar, reducing sugarand nicotine contentw aslow , both ofthese tw o varietiesw ere notharm oniousin intrinsic chem icalcom position and had low industrial utilization, notsuitable for planting in Luliang.W hether “N C 297” and “Y unyan97” w ere suitable for planting locally needs further analysisand validation.
