间作模式下大白茶净光合速率的影响因子分析

为分析间作模式下大白茶(Koilodepas hainanense)净光合速率的影响因子,在生长初期(5月)、生长盛期(6月)和生长末期(10月)分别对大白茶茶树的净光合速率和对其影响的相关指标进行测量.结果表明,间作模式下3个时期茶树净光合速率变化均为单峰曲线.在影响净光合速率的指标中,光合有效辐射是主导因素,并和气温、胞间CO2浓度和气孔导度共同作用影响净光合速率.

Study on Influence factor of Net Photosynthetic Rate of Tea(Koilodepas hainanense) under Interplant Patterns

In order to analyze the influence factors of photosynthetic of tea under interplant patterns.The photosynthesis of tea(Koilodepas hainanense) tree;and the indicators of influencing photosynthetic rate were measured at initial vegetal stage(May),blooming vegetal stage(June) and final vegetal stage(October).The results showed that the net photosynthetic rate presented a single peak curve in three different vegetal stages.Photosysthetic available radiation was the dominant factor among the indicators affecting net photosynthetic rate.It influenceed the photosynthetic rate together with temperature,intercellular CO2 concentration and stomatal conductance.
