针对切花红掌日光温室冬季生产时CO_2亏缺严重的现象,以不增施CO_2为对照,研究了增施700、1000、1300μmol·mol~(-1)浓度CO_2对切花红掌‘火焰’光合特性和生长发育的影响.结果表明:增施60 d CO_2,红掌叶片的净光合速率、胞间CO_2浓度和水分利用效率均显著提高,且以1000μmol·mol~(-1)处理的增幅最大;而气孔导度则较对照显著下降.增施CO_2后,红掌叶片的可溶性糖、淀粉和可溶性蛋白含量均较对照显著增加,佛焰苞大小、色泽、花茎长度等切花品质参数,以及叶片发育质量参数和花茎生长速率均有不同程度的提高,且均以1000μmol·mol~(-1)浓度最佳.增施1000μmol·mol~(-1)的CO_2可以有效促进日光温室切花红掌的冬季生产. Aiming at the serious deficit of CO_2 during the winter production of Anthurium andraeanum in greenhouse, the effects of CO_2 at 700, 1000 and 1300μmol · mol -1 on the photosynthesis of Anthurium andraeanum The results showed that the net photosynthetic rate, intercellular CO 2 concentration and water use efficiency of Anthurium were significantly increased after 60 days of CO 2 application, and the highest increase was observed with 1000 μmol · mol -1 While the stomatal conductance decreased significantly compared with the control.After adding CO_2, the content of soluble sugar, starch and soluble protein of Anthurium andraeanum increased significantly compared with the control, and the quality parameters of cut flower such as size, color, The developmental quality parameters and the growth rate of stems all increased to some extent, and the optimum concentration was 1000μmol · mol -1 .The addition of 1000μmol · mol -1 CO 2 could effectively promote the growth of Anthurium andraeanum Winter production.
