A light absorption model (LAM) for vegetative plant canopies has been derived from the Suits reflectance model. From the LAM the absorption of light in the photosynthetically active region of the spectrum (400-700 nm) has been calculated for a Penjamo wheat crop for several situations including (a) the percent absorption of the incident radiation by a canopy of LAI 3.1 having a four-layer structure, (b) the percent absorption of light by the individual layers within a four-layer canopy and by the underlying soil, (c) the percent absorption of light by each vegetative canopy layer for variable sun angle, and (d) the cumulative solar energy absorbed by the developing wheat canopy as it progresses from a single layer through its growth stages to a three-layer canopy. This calculation is also presented as a function of the leaf area index and is shown to be in agreement with experimental data reported by Kanemasu on Plainsman V wheat.
一种用于植物营养冠层的光吸收模型（LAM）是从休茨反射率模型推导出来的。根据该光吸收模型，已针对彭贾莫小麦作物的几种情况计算了光合有效光谱区域（400 - 700纳米）的光吸收情况，包括：（a）叶面积指数为3.1且具有四层结构的冠层对入射辐射的吸收百分比；（b）四层冠层内各层以及下层土壤对光的吸收百分比；（c）不同太阳角度下各植物冠层层对光的吸收百分比；（d）生长中的小麦冠层从单层生长到三层冠层过程中吸收的累积太阳能。该计算结果也表示为叶面积指数的函数，并显示与卡内马苏报道的关于普莱恩斯曼V型小麦的实验数据一致。
