以黄菇娘为试材,采用直角双曲线修正模型、分段函数等5种模型对黄菇娘的光响应及CO2响应曲线进行拟合,研究相关光合参数的变化,比较其拟合效果。结果表明:5种模型中以直角双曲线修正模型、分段函数的拟合效果较好。直角双曲线与非直角双曲线2种模型的LSP、CSP远小于观测值,而Pmax和Amax也远大于观测值。二次多项式的光响应曲线预测值与实测值相对偏离较大,尤其在弱光区域(0~400μmol·m-2·s-1),LCP为负值。
The light response and CO2 response curve of Huanggunsiang were fitted with five models including rectangular hyperbolic correction model and piecewise function. The changes of photosynthetic parameters were studied and their fitting effects were compared. The results show that the correction model of rectangular hyperbolic curve in the five models is good, and the fitting effect of piecewise function is better. The LSP and CSP for the two models of rectangular hyperbola and non-rectangular hyperbola are much smaller than the observed values, while Pmax and Amax are much larger than the observed values. The quadratic polynomial light response curve predicted deviate from the measured value, especially in the low light region (0 ~ 400μmol · m-2 · s-1), LCP negative.
