油菜是喜硼作物，特別是甘藍型雜交油菜，對硼素營養尤為敏感。缺硼會導致油菜生長不良，特別是花蕾和角果退化，產生"花而不實"現(xian)象(xiang)，導(dao)致(zhi)油(you)菜(cai)產(chan)量(liang)大(da)幅(fu)度(du)降(jiang)低(di)，嚴(yan)重(zhong)時(shi)甚(shen)至(zhi)絕(jue)收(shou)。我(wo)國(guo)土(tu)壤(rang)中(zhong)硼(peng)的(de)含(han)量(liang)總(zong)體(ti)偏(pian)低(di)，不(bu)能(neng)滿(man)足(zu)油(you)菜(cai)生(sheng)長(chang)的(de)需(xu)要(yao)，因(yin)此(ci)
，必(bi)須(xu)通(tong)過(guo)人(ren)工(gong)施(shi)硼(peng)來(lai)彌(mi)補(bu)不(bu)足(zu)。但(dan)實(shi)踐(jian)中(zhong)，農(nong)民(min)朋(peng)友(you)在(zai)進(jin)行(xing)油(you)菜(cai)施(shi)硼(peng)時(shi)，必(bi)須(xu)走(zou)出(chu)以(yi)下(xia)3個誤區：

、出苗
、生長有嚴重抑製作用，造成"硼中毒"。一般來說，底肥宜畝施硼砂0.5-1千克
，以畝葉麵噴施0.2-0.4%硼砂水溶液50千克為宜。

誤區二：缺硼會造成油菜"花而不實"，suoyihuaqipenpengxiaoguozuihao。zhongsuozhouzhi，youcaidezhenggeshengchangjieduandouxuyaopeng，yibanyimiaoqiheleitaiqiyemianpenpengweiyi，huaqipenpengweishiyiwan
