摘　　要：针对洞庭湖地区油菜常规施硼（叶面喷施）效果不稳定的问题,于2004~2005年在沅江市北部垸田区进行了油菜不同施硼方法的试验。结果表明,硼肥基施加叶面喷施比单纯叶面喷施效果更佳,以基施7 500 g/hm2＋喷施1 500 g/hm2增产效果最好,经济效益最高,可在生产上推广应用。To solve the problem of instability of effect of spraying boron fertilizer on rape leaf surface in Dongting Lake area, a field experiment on different fertilization patterns of boron fertilizer, foliage spraying （FS） and basal application in soil and foliage spraying （BA＋FS）, was conducted in north of Yuanjiang city in 2004~2005. The results showed that the yield of rape in BA＋FS treatment was higher than that in FS treatment. The increasing effect on yield and economic benefit was highest under application boron fertilizer 7 500 g/hm^＋ in soil and spraying 1 500 g/hm^2 on leaf surface.
