摘要: 对于稻、麦和玉米,群体穗数(Y)和种植密度(x)的数量关系,可用变形双曲线方程 Y=x/(a+bx)作有理描述。本文讨论了该方程的基本性质;并由之推出17个公式,用以表示穗数和密度数量关系上的各种特点。此外,也讨论了从穗数——密度的实验数据建立该方程的具体方法,并附实例。

Abstract: In respect to rice,wheat and corn crops,the quantitative relation of planting rate (x)to the number of heads or ears per mu (Y) may be expressed by modified hyperbolic equation:Y=x/(a+bx) (3)where“a”and“b”are two positive parameters.The value of“a”is the regression coefficient of1/yon1/x,which
