| 摘 要： | 对温室栽培条件下桃(早红株、早红霞)净光合速率的测定结果表明,桃的净光合速率Pn日变化曲线呈明显的三峰曲线;铺设反光膜、吊反光幕以后,桃Pn日变化趋势没有发生改变,但同期Pn值有明显增加。日平均Pn增长17.8%。加富CO2后温室桃Pn的日变化曲线由三峰曲线变成双峰曲线,日平均Pn提高21.7%。 |

| Abstract: | The net photosynthesis(Pn) of peach(Zaohongzhu and Zaohongxia) were studied in greenhouse.The resullts were as follows:The diurnal variation trend of Pn of peach was a three-peak curve in greenhouse,after reflection of light film laid,the diurnal variation trend of Pn of peacht have notchanged,but Pn has markedly increased in same time,the diurnal average Pn of peach has increased 17.8%.After CO2 enrichment inside the greenhouse,the diurnal curve of Pn of peach has changed a two-peak and Pn was 21.7% higher than that of control. |
