推导了具有随机叶片的水平均匀作物冠层（如饲料作物或谷物）瞬时光合作用的解析模型。该模型基于叶片光合作用对辐照度的响应的非矩形双曲线的使用，以及用于树冠截光特性的monsig - saeki理论。提出了一种在光照和温度波动条件下计算日冠层光合作用的近似方法，其精度估计为。gtoreq。1.5%。
An analytical model of instantaneous photosynthesis for a horizontally homogeneous crop canopy with random leaves (e.g., forage crops or cereals) is derived. The model is based on the use of a non-rectangular hyperbola for leaf photosynthetic response to irradiance, and the Monsi-Saeki theory for the light-intercepting characteristics of the canopy. An approximate method for calculating daily canopy photosynthesis in fluctuating light and temperature conditions is developed, with an accuracy estimated at .gtoreq. 1.5%.
