摘要： 本文通过实测并采用叶片受光加权法获得水稻群叶光照率(Rj)及各层群叶的总光照率(Rs)。与理论计算法比较,本方法更接近实际的群叶光照度。实际测定表明,水稻群体边界群叶光照比率(A)与群体平均叶片倾斜角a之间、根据群体内光通量计算的消光系数(K)与根据群叶光照度计算的消光系数(K′)之间分别存在极显著的直线关
Abstract: A weighted average method is used to measure the illumination oneach plant and the amount of light intercepted by each layer of ricefoliage.As there is a significant linear relation between the illumination ra-tio on the margin of rice canopy(A)and the mean leaf inclination an-gle of rice foliage(?)
