During 2015-2016, five boron treatments were applied to Huaza 9 and Zhongshuang 11 at the experimental field of Tongren University, as B0(0 kg/hm2), B1(3.75 kg/hm2), B2(7.50 kg/hm2), B3(15.00 kg/hm2), and B4(30.00 kg/hm2)of boron per hectare. The effects of boron fertilizer application rate on rapeseed yield, yield components and utilization efficiency of boron fertilizer were studied. The results showed that the application of boron fertilizer could increase the parameters of rapeseed including stem diameter, number of branches, number of pods and pods per plant. The number of kernels per pod, grain yield, and pod yield and aboveground yield were significantly affected, and the boron content and boron accumulation in different parts of rapeseed increased with the increase of boron application. The content of boron and the accumulation of boron in different parts of rapeseed increased with the increase of boron application. Within the range of 3.75-30.00 kg/hm2, B1 had the highest apparent utilization rate, agronomic utilization rate and physiological utilization rate of boron fertilizer, followed by B3. Considering the agronomic characters, yield and utilization efficiency of boron fertilizer, it is recommended that the amount of boron fertilizer used in this rapeseed planting area should be about 15.00 kg/hm2.
