| 摘 要： | 对栗茶间作模式和单作模式下茶树叶片的光合生理生态特征分析表明,栗茶间作模式下净光合速率(Pn)日变化为单峰曲线,单作模式下净光合速率(Pn)日变化为双峰曲线;栗茶间作模式下茶树净光合速率(Pn)与胞间CO2浓度(Ci)和光合有效辐射(PAR)和大气温度(Ta)和叶面温度(Tl)呈显著相关,单作模式下茶树净光合速率(Pn)与胞间CO2浓度(Ci)和蒸腾速率(Tr)呈显著相关;栗茶间作模式和单作模式的回归方程分别为Pn=12.8713-0.0267Ci,Pn=23.1111+22.7827Cond-0.0770Ci.

| Abstract: | A series of physiological characteristics of the tea leaves photosynthesis and environmental factors in the intercropping pattern of Chinese chestnut with tea and in monoculture were studied.The results indicate that diurnal variation of net photosynthesis rate(Pn)in intercropping pattern of Chinese chestnut with tea assumed single peak curve,diurnal variation of Pn in monoculture assumed double peak curve;photosynthetic available radiation(PAR),intercellular CO2 concentration(Ci),air temperature(Ta),leaf temperature(Tl)had positively relationship with Pn in intercropping pattern.Ci,transpiration rate(Tr)had positively relationship with Pn in monoculture;the regression equation of the intercropping pattern and monoculture are Pn=12.8713-0.0267 Ci,Pn=23.1111+22.7827 Cond-0.0770 Ci,respectively. |
