所谓株高构成指数,是指小麦茎秆上下节间长度存在一定比例。这种比例关系,其数值为任一节间长度与该节间加下一节间长度之和的比值。我们知道,把长为1的线段分成两部分,使其较长部分正好是全线段和另一部分的比
The so-called plant height composition index refers to the length of the upper and lower stems of wheat stalk there is a certain proportion. This ratio, the value of any length of an internode plus the length of the next internode length ratio. We know that the length of the line segment is divided into two parts, so that the longer part of exactly the same length and the other part of the ratio
