The invention discloses a phosphorus non-point source pollution control method for yellow soil slope cropland oilseed rape cultivation. The method includes optimized fertilization cross slope ridge culture, contour living hedgerow arrangement and straw mulching. The method is obvious in technical effect, simple and convenient in operation and high in technique integration. Shortcomings of severe water and soil loss, high runoff producing coefficient and high runoff phosphorus loss rate of a traditional cultivation method are overcome. The technique effectively controls generation of overland runoff of yellow soil slope cropland and reduces total phosphorus output; the runoff producing coefficient is 11.59% and the phosphorus loss coefficient is 0.115, which are distinctively lower than those of the traditional cultivation method. The control method provided by the invention is an effective measure for reducing agricultural phosphorus non-point source pollution risks. 本发明公开了种黄壤坡耕地油菜种植磷面源污染控制方法，包括优化施肥、横坡垄作、等高植物
