摘要

2015—2016年,在贵州省铜仁学院试验基地,以华杂9号和中双11号为试验材料,设置5个硼肥施用量处理,即B0(0 kg/hm~2)、B1(3.75 kg/hm~2)、B2(7.50 kg/hm~2)、B3(15.00 kg/hm~2)和B4(30.00 kg/hm~2),研究硼肥施用量对油菜产量、产量构成因子以及硼肥利用率的影响。结果表明:增施硼肥可提高油菜植株茎粗、分枝数、分枝角果数和单株角果数等性状参数值;对每角粒数、籽粒产量、角果皮产量、地上部产量影响显著;油菜各部位的硼素含量及硼素累积量随着施硼量的增加而不断提高;施硼量在3.75～30.00 kg/hm~2,B1处理硼肥的表观利用率、农学利用率和生理利用率最高,其次是B3处理的;综合油菜的农艺性状、产量及硼肥的利用效率考虑,推荐贵州省油菜种植区的硼肥使用量为15.00 kg/hm~2左右。
        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/hm~2), B1(3.75 kg/hm~2), B2(7.50 kg/hm~2), B3(15.00 kg/hm~2), and B4(30.00 kg/hm~2)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/hm~2, 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/hm~2.
