摘要:
以巨菌草为试材，采用盆栽控水试验法，研究了光合-光响应曲线模型-指数模型、直角双曲线模型、非直角双曲线模型及直角双曲线修正模型对巨菌草光合-光响应的适应性，以期为巨菌草合理灌溉及水分亏缺时模型的准确选择提供参考依据。结果表明:光合-光响应曲线会随着调亏灌溉的程度和调亏灌溉处理后处理时间延长而发生变化，亏缺程度和亏缺时间对光合-光响应曲线有叠加效应。模型验证发现，适宜水分亏缺条件下巨菌草的光合-光响应曲线模型为非直角双曲线模型。
Abstract:
In order to reveal the photosynthetic physiological response mechanism of Cenchrus sp.under different water irrigation conditions， Cenchrus sp.was used as experimental material，the adaptability of photosynthesis light response curve model exponential model，right angled hyperbola model，non right angled hyperbola model and right angled hyperbola modified model to Cenchrus sp.photosynthetic light response were studied，in order to provide reference for the accurate selection of models for rational irrigation and water deficit of Cenchrus sp. The results showed that the photosynthetic light response curve would change with the degree of regulated deficit irrigation and the extension of treatment time after regulated deficit irrigation.The degree and time of deficit had a superimposed effect on the photosynthetic light response curve.The model validation found that the photosynthetic response curve model of Cenchrus sp.under suitable water deficit conditions was a non right angle hyperbola model.
