云南陆良地区6个主栽烤烟品种适宜性分析

发布时间:2019-08-23 来源: 感恩亲情 点击:


  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。

  Abstract:In order to study the suitability of dieffrent flue-cured tobacco varieties in Luliang,Yunnan,241 flue-cured tobacco middle leaves of grade C3F about 6 dieffernt varieties were collected and analyzed in 2010. Results indicated that “NC102” and “Hongda” had good synthetical character:leaf appearance and physical porperties were outstanding,intrinsic chymic composition was in harmonious proportions,all the indicators were in proper range of high quality flue-cured tobacco and fitted for industrially utilizing,both were suitable for planting in Luliang. The difference of total sugar and reducing sugar,stalk and starch content of “K326” was on the highside and the density of leaf was low. The stalk ,starch and nitrogen content of “Yunyan87” was on the highside,while the total sugar,reducing sugar and nicotine content was low,both of these two varieties were not harmonious in intrinsic chemical composition and had low industrial utilization,not suitable for planting in Luliang.Whether “NC297” and “Yunyan97” were suitable for planting locally needs further analysis and validation.

  烤烟品种是烟叶生产的重要物质基础,选择适宜的烤烟栽培品种是获得高品质烟叶的前提[1-2]。烟叶品质的形成是遗传因素、栽培措施和生态环境共同作用的结果[3]。生态因素是品质特点和风格区域特色形成的基础条件[4]。品种和栽培措施是人为可控因素,而生态因素作为影响烤烟生长的主要因素不能人为控制,温度、水分、光照等气候条件对烤烟的生长影响作用巨大。因此,研究烤烟产区特定生态环境下的品种适宜性,合理布局,制定与当地生态条件相适宜的栽培品种和生产措施,对于优质烟叶的生产具有重要的现实意义。
  1 材料与方法
  1.1 试验材料
  2010年,在云南陆良县烤烟原料基地单元进行了大规模取样,按照GB2635-1992烤烟分级技术要求,在各点取烤后C3F烟叶各1.5 kg,用于常规理化性状分析。所取样品为当地主栽品种,K326、NC102、NC297、云烟87、云烟97和红花大金元(红大)分别取样28、24、24、109、35和21个, 6个品种共计241个烟叶样品。
  1.2 测定指标及方法
  总氮、总糖、还原糖、烟碱、氯的含量按照YC/T 159~162-2002《烟草及烟草制品水溶性糖(总植物碱、总氮、氯)的测定连续流动法》中的方法测定,所用仪器为德国布朗卢比公司制造的AA3型流动分析仪;钾含量采用火焰光度计法测定;淀粉含量采用蕙酮比色法测定,标准烟样由湖南农业大学烟草研究院提供。数据采用DPS7.05和Excel软件进行统计分析。
