Abstract: For exploring the suitable sowing and transplanting time of the flue-cured tobacco in Longhui flue-cured tobacco planted areas, xiangyan3 as a material, the evaluation of the flue-cured tobacco appearance quality, the economic character index(ECI) and chemical components usability index(CCUI) of the principal grade flue-cured tobacco leaves with different seeding and transplanting time was made by a fuzzy evaluating and weighted method in 2014 and 2015. The result shows as follow: the score of appearance quality index evaluation, the economic character index(ECI) and chemical components usability index(CCUI) of the principal grade flue-cured tobacco leaves, and the weighted value of the three indexes are the best with the treatments of “seeding on 30th Dec. and transplanting on 4th Apr.”. With the delay of the sowing and transplanting time, variation of score of appearance quality index evaluation, ECI and CCUI of the principal grade flue-cured tobacco leaves follows the law of “low-high-low”. Based on the above mentioned analysis, the suitable seeding time in the Longhui areas is late Dec. to early Jan. and transplanting from the end of Mar. to early Apr.”, which brings the benefit of increased yield and quality. This study provides the theoretical basis for setting suitable flue-cured tobacco seeding and transplanting time in Longhui flue-cured tobacco planting areas.

摘要: 为探索隆回烟区烤烟适宜播种移栽期,以湘烟3号烤烟品种为材料,采用模糊数学和加权法,对2014-2015年隆回烤烟不同播种移栽期烟叶的外观质量、主要等级烟叶经济效果指数(ECI)和化学成分可用性指数(CCUI)3项指标进行评价。结果表明,烟叶外观质量指标评价得分、主要等级烟叶ECI和CCUI这3项指标的加权值,均以“12月30日播种4月4日移栽”的处理最高,随着播种移栽期的推迟,采烤后主要等级烟叶ECI和 CCUI均呈现 “低-高-低”的变化规律。综上可知,隆回烟区适宜的播种移栽期范围是12月底到1月初播种,3月底到4月初移栽,这将有利于提高烟叶整体质量和产值。本研究为隆回烟区优质烤烟生产适宜播种移栽期的确定提供了理论依据。
