为了估计作物的叶面积,考虑到必须有一个简单而比较迅速的方法。密勒(Miller)等提出所谓叶乘积的方法,即(K-常数×长度×宽度),认为比其他方法,如用面积计、光电管或干量法更为适宜。斯的克勒(Stickler)等用此法为高粱找到一个叶乘积常数(K=0.747)对六个杂交种都可适用。皮希雪诺(Bhishnoi)却观察到这样一个常数对一个甜高粱品种(K=0.795)和一个非甜高梁品种(K=0.680)有显
In order to estimate the leaf area of a crop, consideration must be given to a simple and quick method. Miller et al. Propose a so-called leaf product method (K-constant × length × width) which is considered to be more suitable than other methods such as area measurement, phototube or dry-method. Stickler et al. Found a leaf product constant for sorghum using this method (K = 0.747) for all six hybrids. Bhishnoi observed that such a constant was significant for a sweet sorghum cultivar (K = 0.795) and for a non-sweet sorghum cultivar (K = 0.680)
