摘    要:运用系统聚类的方法,研究了不同施肥处理下的中龄油茶的光合生理指标,结果表明,不同施肥处理的油茶在净光合速率、水分利用率、气孔导度等生理指标上存在明显的差异,这些生理指标的综合作用决定了油茶的光合特性和产量水平。施肥处理对油茶光合性能具有很好的改善作用,不施肥或施过量的肥料对油茶光合性能影响均不明显,要提倡平衡施肥。

关 键 词:油茶  光合生理特性  平衡施肥

Abstract:The system cluster analysis was used to study the photo-biological indexes of mddle-aged oil-tea.The result indicated that different fertilizing treatments had obvious diversity in the indexes of photosynthesis rate(Pn),water using efficiency(WUE),stomatal conductance(Cs),and so on.The synthetical effect of all these physiological indexes decided the photo-biological characters and output of oil-tea.Fertilization improved the photo-biological characters of oil-tea,on the contrary,no fertilization or over fertilization had little effect on the photo-biological characters,so balanced fertilization should be recommended.
Keywords:oil-tea  photo-biological characters  balance fertilization
