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/m2)的幂函数模型:y=169437x-2(R2=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。
Based on the analysis of the relationship between plant height and transplanting density of rice, a golden section optimization method was proposed to determine the reasonable ratio of row spacing in rice, which was dependent on the plant height (x, cm) was calculated as follows: Row spacing (cm) = 0.309 x, Plant spacing (cm) = 0.191 x. The power function model of high density rice plant was established: y = 169437x- 2 (R2 = 1). The line spacing and transplanting density of representative rice cultivars, which were determined by this method, were consistent with the current high yielding cultivation of rice.
