摘　　要：田间试验和定位试验结果表明，在土壤有效硼含量≤０．３３ｍｇ·ｋｇ－１的缺硼土壤上栽培油菜，底施硼肥较叶面喷硼的增产效果好，一般亩施硼砂０．４—０．５ｋｇ能满足油菜丰产对硼的需要，但需年年施硼．油菜底施硼肥可节省人工，投资少，增产显著．Plot and fixed position experiments were conducted,and the results indicated that applying boron as base fertilizer could increase yield of rape more significantly than spraying it on leaves in boron-deficiency soil (the soil available boron content≤0. 33mg.kg-1). In general, 0. 4 to 0. 5 kilogram sodium borate per mu was enough for rape growth,but it was necessary to apply boron fertilizer every year. The results also showed that base boron fertilizer could simpfy the fertilizing procedure but increase rape yield.
