The application effects of organic boron on oilseed rape {Brassica nap us L) production were studied. The results showed that after treated by 1.50 mg/L of boron,plant height was increased by 8.95%; and height of first branch was decreased by 39.96%. The number of first branches and secondary branches increased *by 15.91% and 29.67% respectely. The chlorophyll contents of main stem leaf were increased; and chlorophyll fluorescence parameters were improved. The effective pods per main stem and per plant were increased by 24.44% and 33.26%. The seed yield per 666.67m2 was increased by 37.06% after organic boron treatment.%采用有机态硼肥(国家发明专利号:ZL200810243821.2)在油菜薹期施用,研究其对油菜的生长、主茎托叶叶绿素含量和荧光特性以及产量的影响.结果表明,在有效硼浓度为1.50 mg/L处理后植株高度增加8.95％,而一次分枝高度比对照降低39.96％,一次分枝数和二次分枝数分别增加15.91％和29.67％.同时能够提高油菜主茎托叶叶片中的叶绿素含量和改善叶绿素的荧光动力学参数.主茎英数、单株总英数和产量分别比对照提高24.44％、33.26％和37.06％.
