为了探讨水稻高产栽培合理的株行距配比和栽插密度,在分析水稻株高与栽插密度关系的基础上,提出了确定水稻合理株行距配比的黄金分割优选法,即依赖于水稻株高（x,cm）的株行距配比为：行距（cm）=0.309 x,株距（cm）=0.191 x,建立了水稻株高密度（y,穴/m^2）的幂函数模型：y=169437x^-2（R^2=1）。应用该方法确定的目前生产上具代表性水稻品种的株行距和栽插密度,符合当前水稻高产栽培要求。

To explore the rational plant-row spacing and hill density for rice high-yielding cultivation,relationship between plant height and planting density in rice was analyzed.On this basis,golden section method was presented for determining the rational plant-row spacing,which depended on the plant height（x,cm） and could be calculated as follows： row spacing（cm）=0.309x,plant spacing（cm）=0.191x.In addition,power function model for describing relationship between the plant height and hill density（y,hills/m2） was established as follows：y=1694...
