摘 要:
对温室条件下杏（金太阳、凯特）净光合速率进行了测定，系统分析了它们的日变化规律。杏的净光合速率Pn的日变化曲线呈明显的双峰曲线。铺设反光膜、吊反光幕以后，杏Pn日变化趋势没有发生改变，但同期Pn值明显增加，日平均Pn增长19％。加富CO2后杏Pn的日变化曲线由双峰曲线变成单峰曲线，日平均Pn提高18．12％。[著者文摘]

Abstract:
The net photosynthesis（Pn） of Aprecot （Jintaiyang and Kaite） were studied in greenhouse. The resullts were as follows. The diurnal variation trend of Pn of Aprecot was a double-peak curve in greenhouse. After reflection of light film laid, the diurnal variation trend of Pn of Apricot have not been changed, but Pn has markedly increased in same time, the diurnal average Pn of Apricot has 19% . After CO2 enrichment in the greenhouse,the diurnal curve of Pn of Apricot has changed a onepeak and Pn was 18.12% higher than that of control piot.[著者文摘]
