【摘要】 以茶肥1号为材料,圆叶决明、草决明为对照,对不同时期的净光合速率、光和二氧化碳响应特性以及不同叶位光合速率进行研究。结果表明,各时期茶肥1号净光合速率最高,与对照达极显著差异;茶肥1号净光合速率、表观量子效率、光饱和点、羧化效率高,二氧化碳补偿点低是茶肥1号光合优势集中体现,冠层整体叶片光合优势是茶肥1号高产青量的主要因素。更多还原

【Abstract】 Net photosynthesis rate(Pn) of Chafei 1#(Cassia sophera L),Cassia rotundifolia,Cassia in different periods,photosynthesis rate response for light and for carbon dioxide was investigate,.The result shows that Pn of Chafei 1# was highest among three green manures in different period,which have significant difference.The Pn,apparent quantum yield(AOY),light saturation point,carbon efficiency of Chafei1#higher that of the other two green manures,and the carbon compensate point of Chafei1#is lower,which are the advantages of photosythetic characteristic of Chafeil#.The pn of canopy photosynthesis another reason for high biomass for Chafeil#.更多还原
