摘　　要：通过田间试验,研究磷肥与油菜产量、品质和植株形态之间的关系,确定油菜高产、优质、高效的磷肥施用量。不同油菜品种磷肥用量试验的结果表明:①每公顷施纯磷360kg的处理,中双9号,每公顷产量达3301.65kg,中油杂2号,产量达到最大值,每公顷产量3781.95kg。②一次分枝对产量影响最大,二次分枝、主花序的贡献相对要小得多。③随着施磷量的增加单位面积有效角果数呈增长的趋势。Through the field trial, the relationship between phosphorus application and yield, quality and plant shape are researched, and the optimum rate of phosphorus application is defined. The yield of Zhongshuang No.9 reaches 3 301.65 kg·ha^-1 in the treatment of purified phosphorus 360kg·ha^-1. In the term of Zhongyouza No.2, its largest yield is 3 781.95kg·ha^-1 in the same treatment. First branch affects yield more than second branch and main inflorescence. Effective pod number showes enhancing trend accompanied with the increasing of phorsphorus.
