１８个供试土壤平均有效硼含量为０．５３ｍ ｇ／ｋｇ。油菜ＮＰＫＢ处理平均产量为１８７２．３ｋｇ／ｈｍ ２，ＮＰＫ区（无硼）相对产量为６６．１％ ，施硼油菜平均增产６１１．４ｋｇ／ｈｍ ２，增产率达４８．５％ 。生产百千克油菜籽需硼量为５．０７ｇ，土壤供硼率为６２．７％ 。硼肥的当季平均利用率为４．３％ ，土壤有效硼含量与无硼区油菜籽相对产量呈极显著相关，ｒ＝ ０．５９９１，ｎ＝ １８；与油菜施硼增产量之间达极显著负相关，ｒ＝ － ０．６６１０，ｎ＝ １８。供试土壤有效硼临界值为０．５６ｍ ｇ／ｋｇ。
The average available boron content of 18 tested soils was 0.53 m g / kg. The average yield of rapeseed NPKB was 1872.3kg / hm 2, and the relative yield of NPK (no boron) was 66.1%. The yield of rapeseed was increased by 611.4kg / hm 2 and the yield was 48.5%. The production of one hundred kg of rapeseed requires 5.07g boron and the boron supply rate of the soil is 62.7%. The seasonal average utilization rate of boron fertilizer was 4.3%. The available boron content in soil was significantly correlated with the relative yield of non-boron rapeseed (r = 0.5991 **, n = 18) Significantly negative correlation between the r = - 0.6610 **, n = 18. The critical value of available boron in soil is 0.56 m g / kg.
