采用双因素随机区组试验,研究密度、留叶数及其互作对烤烟(云烟97)光合特性、经济性状的影响。结果表明,密度、留叶数及其互作对烤烟光合特性、经济性状产生显著影响,且留叶数效应较大,密度和互作效应较小。同一留叶数下,随密度增加,光合速率(Pn)、气孔导度(Gs)、胞间 CO2浓度(Ci)、蒸腾速率(Tr)、叶绿素含量均表现出先升高后降低的趋势;低、中密度下,Pn、Gs、Ci、Tr、叶绿素含量随留叶数增加,均逐渐升高,高密度下则先升高后降低。不同处理的光、CO2响应曲线类型均相同,但曲线参数存在差异,低、中密度下,随留叶数增加,最大Pn逐渐升高,高密度下则先升后降。相同密度下,烤烟产量、产值均随留叶数增加而显著上升;留叶数一定时,随密度增大,产量呈上升趋势,但产值先升后降。综合分析,密度16500株/hm2、留叶23片/株效果最好;理论适宜密度、留叶数范围分别为17093~17665株/hm2、21.3~23.1片/株。
採用雙因素隨機區組試驗,研究密度、留葉數及其互作對烤煙(雲煙97)光閤特性、經濟性狀的影響。結果錶明,密度、留葉數及其互作對烤煙光閤特性、經濟性狀產生顯著影響,且留葉數效應較大,密度和互作效應較小。同一留葉數下,隨密度增加,光閤速率(Pn)、氣孔導度(Gs)、胞間 CO2濃度(Ci)、蒸騰速率(Tr)、葉綠素含量均錶現齣先升高後降低的趨勢;低、中密度下,Pn、Gs、Ci、Tr、葉綠素含量隨留葉數增加,均逐漸升高,高密度下則先升高後降低。不同處理的光、CO2響應麯線類型均相同,但麯線參數存在差異,低、中密度下,隨留葉數增加,最大Pn逐漸升高,高密度下則先升後降。相同密度下,烤煙產量、產值均隨留葉數增加而顯著上升;留葉數一定時,隨密度增大,產量呈上升趨勢,但產值先升後降。綜閤分析,密度16500株/hm2、留葉23片/株效果最好;理論適宜密度、留葉數範圍分彆為17093~17665株/hm2、21.3~23.1片/株。

A field experiment was conducted using two-factor randomized complete block design to investigate the effects of density (D), number of leaves remained (L) and their interaction on photosynthetic characters and economic traits of flue-cured tobacco (cv Yunyan 97). The results showed that D, L and their interaction had significant effects on photosynthetic characters and economic traits of flue-cured tobacco, and the responses from the D were greater than those from L and their interaction. Under same L condition, Pn, Gs, Ci, Tr and chlorophyll content increased first and then declined as D increased. As for the low and medium D conditions, with L increasing, Pn, Gs, Ci, Tr and chlorophyll content increased gradually, but they increased first, and decreased later under high D conditions. In addition, light and CO2 response curve type from all treatments were the same, but response curve parameters were different. With L increasing, maximum Pn rised gradually under low and medium D conditions, while increased first, and decreased later under high conditions. With L increasing, both yield and output value increased significantly under seam D conditions;under seam L conditions, yield rised gradually, but output value increased firstly and then declined, when D increased. On the consideration of comprehensive analysis, effect of 16500/23 treatment was best; and theoretically the appropriate D and L for Yunyan 97 were 17093-17665 plant/ha and 21.3-23.1 leaves/plant respectively.
