摘　　要：为研究不同施硼水平对油菜生物学性状和产量的影响,选用秦优10号,采用田间裂区做试验。结果表明,适量硼肥可以促进油菜植株生长,表现为增加油菜分枝节位、主花序的长度和分枝数的数量。硼肥量为30 kg/hm^(2)时,分枝节位长度最长;硼肥量为15 kg/hm^(2)时,主花序长度最长;硼肥量为22.5 kg/hm^(2)时,分枝数最多;施硼量为15 kg/hm^(2)时,油菜有效角果数、每角粒数和产量均达到最高,产量最高为2061 kg/hm^(2)。综合分析硼肥推荐施用量为15 kg/hm^(2)较为适宜。In order to study the effects of different boron application levels on the biological characters and yield of rapeseed,Qinyou 10 was selected and the field split-plot test was used.The results shows that an appropriate amount of boron fertilizer can promote the growth of rapeseed plants,which is manifested by increasing the length of rapeseed branch nodes and main inflorescences and the number of branches.The branch node length is longest when the boron fertilizer amount is 30 kg/hm^(2),the main inflorescence length longest when the boron fertilizer amount is 15 kg/hm^(2),the number of branches highest when the boron fertilizer amount is 22.5 kg/hm^(2),and the number of the effective horn fruit,the number of grains per horn and yield of rapeseed reaches the highest when the boron fertilizer amount is 15 kg/hm^(2),and the highest yield is 2061 kg/hm^(2).Comprehensive analysis showed that the recommended application rate of boron fertilizer is 15 kg/hm^(2).
