摘　　要：为探讨高海拔烟区烟苗移栽期对烟株农艺性状、经济性状、外观质量、化学成分和成熟期烟叶酶活性的影响,于2011年在贵州省威宁县采用随机区组设计,进行了田间不同移栽期试验。结果表明:随移栽期提早,烟株发育提前,移栽到现蕾的时间延长,大田生育期延长;农艺性状各生育期变化不同。总体上株高、叶数和茎围随移栽期的推迟而降低,最大叶长和最大叶宽随移栽期的推迟先升高后降低;产量和上中等烟率随着移栽时间推迟而降低,产值、均价和上等烟率则以当地移栽时间的最高,其余表现为随着移栽时间推迟而降低;中上部烟叶的身份随移栽期的推迟而变薄,上部烟叶色度随移栽期的推迟而变弱,上部烟叶烟碱含量随移栽期的推迟而升高,中部及上部烟叶成熟期的POD和CAT活性随移栽期的推迟而增加,中部叶的SOD先增加后降低,上部叶的SOD随移栽期的推迟而升高。By using randomized block design, various transplanting tests were carried out to study effects of transplanting periods on agronomic traits, economic characters, appearance quality, chemical composition and enzyme activity of maturity tobacco in high-altitude area in 2011 in Weining County of Guizhou Provice. The results indicated that with the transplanting date brought forward, the tobacco plants grew earlier, the duration from transplanting to budding and the field growth period were prolonged; The agronomic traits varied in different growth periods, in general, with the transplanting date delayed, the plant height, leaf number and stem girth decreased, the maximum leaf length and width first increased and then decreased; the yield and high-middle class rate decreased, output value, average price and high class rate of tobacco with local transplanting time reached the highest while others decreased; middle and upper leaves got thin, chroma of upper leaves got weakened, nicotine content in upper leaves was enhanced, POD and CAT activity of middle and upper leaves in maturity stage increased, SOD activity of middle leaves first increased and then decreased, and SOD activity of upper leaves increased.
