为了明确潍坊烟区NC55品种适宜的移栽时间,试验设置了4个移栽时间处理(5月2日、5月12日、5月22日、6月1日),以调查移栽时间对烤烟生长发育、光合特性、叶绿素代谢酶活性、经济性状及感官评吸质量的影响。结果表明,移栽时间显著影响烤烟生长、光合特性和叶绿素代谢酶活性。与5月2日移栽相比,推迟移栽缩短了烤烟生长的伸根期、旺长期和采收期,从而缩短了大田生育期。随移栽时间推迟,旺长期、平顶期叶绿素含量和净光合速率显著提高,叶绿素酶和脱镁螯合酶活性显著降低,叶片长宽和单叶重增加;成熟期叶绿素含量和净光合速率显著降低,叶绿素酶和脱镁螯合酶活性显著提高;烟叶均价、上等烟叶比例和烟叶感官评吸质量呈先增加后降低趋势,以5月12日移栽最高,5月22日移栽次之。因此,建议生产上适当推迟移栽,潍坊烟区以5月12日前后移栽至5月22日结束为宜。
為瞭明確濰坊煙區NC55品種適宜的移栽時間,試驗設置瞭4箇移栽時間處理(5月2日、5月12日、5月22日、6月1日),以調查移栽時間對烤煙生長髮育、光閤特性、葉綠素代謝酶活性、經濟性狀及感官評吸質量的影響。結果錶明,移栽時間顯著影響烤煙生長、光閤特性和葉綠素代謝酶活性。與5月2日移栽相比,推遲移栽縮短瞭烤煙生長的伸根期、旺長期和採收期,從而縮短瞭大田生育期。隨移栽時間推遲,旺長期、平頂期葉綠素含量和淨光閤速率顯著提高,葉綠素酶和脫鎂螯閤酶活性顯著降低,葉片長寬和單葉重增加;成熟期葉綠素含量和淨光閤速率顯著降低,葉綠素酶和脫鎂螯閤酶活性顯著提高;煙葉均價、上等煙葉比例和煙葉感官評吸質量呈先增加後降低趨勢,以5月12日移栽最高,5月22日移栽次之。因此,建議生產上適噹推遲移栽,濰坊煙區以5月12日前後移栽至5月22日結束為宜。

To identify the most suitable transplanting time of NC55 in Weifang, A field experiment was conducted with four transplanting time treatments (05/02, 05/12, 05/22, 06/01) to evaluate its effect on growth, photosynthesis characteristics, chlorophyll metabolism enzyme activity, economical character and sensory evaluation in flue-cured tobacco. The results showed that transplanting time had significant effect on growth, photosynthesis characteristics and chlorophyll metabolism enzyme activity in flue-cured tobacco. Compared to 05/02 transplanting, later transplanting shortened its root elongation, vigorous growth and picking stages, thus its growth duration decreased. As the transplanting time delayed, chlorophyll content and net photosynthetic rate significantly increased but Chlase and MDCase activity decreased in vigorous growth and topping stages. But reverse trends were observed in maturing stage. As the transplanting time delay, the rate between tobacco average price and upper-middle-tobacco leaves increased first and decreased afterwards, while sensory and taste quality of flue-cured tobacco showed the opposite trend. So transplanting time of tobacco production may be delayed up to May 12 to May 22 in Weifang.
