摘要：茶叶的产量和品质与生长环境关系非常密切,为探明林分不同郁闭度对茶树光合日变化的影响,本研究以不同郁闭度的栾树(Koelreuteria paniculata)-茶(Camellia sinensis)复合系统中茶树为材料,纯茶园为对照(CK),利用便携式LI-6400光合作用测定仪研究茶树分别在0.3(T1)、0.6(T2)和0.9(T3)郁闭度条件下的光合作用参数日变化。结果表明:随郁闭度增加,茶树光合有效辐射(PAR)和叶片温度(Tl)日均值和差值呈递减趋势,日变化呈单峰曲线;茶树净光合速率(Pn)日均值随郁闭度增加呈递减趋势,均表现双峰型曲线;CK和T1的蒸腾速率(Tr)和气孔导度(Gs)日变化午间受到明显的抑制且呈双峰曲线,T2和T3呈单峰型曲线。
The production and quality of tea were very close to growing environment,in order to clarify the effects of different canopy closure on photosynthetic diurnal variation of tea in forest-tea compound model,this study by using the LI-6400 portable photosynthesis system,the effects of different canopy closure,0.3（T 1）,0.6 （T 2） and 0.9（T 3）,on photosynthetic diurnal variations of tea plants in Koelreuteria paniculata-Camellia sinensis compound systems were studied,with pure tea garden as the control.The results were as follows：with canopy density increased,daily mean value and difference value of radiation （PAR）,leaf temperature （T l） had a descending trend,diurnal variation showed single peak curve.Net photosynthetic rate （Pn） decreased with canopy closure increased and showed double-peak curve.Contrary to T 2 and T 3,stomatal conductance （Gs） and transpiration rate （Tr） were inhibited obviously and showed double-peak curve under CK and T 1 treatment.
