摘要:
采用CI-340便携式光合仪对苏州洞庭山地区柑桔-茶、板栗-茶、杨梅-茶、枇杷-茶、银杏-茶5种当地常见果茶间作模式下茶树光合特征参数日变化进行了研究。结果表明:5种间作模式下茶树的光合特征参数日变化呈单峰曲线,而对照茶树呈双峰曲线。相关性分析表明:当光合有效辐射强度增大,叶片温度会随之升高,导致净光合速率(Pn)升高,蒸腾速率增大,气孔导度增大,胞间CO2浓度减小。枇杷-茶间作模式下的Pn、蒸腾速率、气孔导度和胞间CO2浓度日均值分别为1.46 μmol?m-2?s-1、0.91 mol?m-2?s-1、60.43 mol?m-2?s-1、305.57 μmol?m-2?s-1,是供试的5种间作模式中较有利于茶树生长的,适合在江苏苏州洞庭山地区进行推广种植。
Abstract:
The diurnal variation of photosynthetic characteristic parameters of five local common fruiter-tea intercropping patterns just as orange-tea,Chinese chestnut-tea,waxberry-tea,loquat-tea and gingko-tea in Suzhou Dongting Mountain region was studied using CI-340 portable photosynthesis system.The diurnal variation of photosynthetic characteristic parameters of five tested intercropping exhibited single-peak curve;and the control was double-peak curve.Correlation analysis showed that the leaf temperature increased with the increasing of the intensity of photosynthetic active radiation,which induced the increase of net photosynthetic rate,transpiration rate,stomatal conductance and the decrease of intercellular CO2 concentration.The results showed that the loquat-tea in five tested intercropping patterns was the most beneficial to the growth of tea plants,and is adaptive for cultivation in Suzhou Dongting Mountain region in Jiangsu Province,and its daily mean of net photosynthetic rate,transpiration rate,stomatal conductance,intercellular CO2 concentration was 1.46 μmol?m-2?s-1,0.91 mol?m-2?s-1,60.43 mol?m-2?s-1,305.57 μmol?m-2?s-1 respectively.
