一、硼肥蔬菜缺硼表现在植株茎叶柄变粗、变脆易分裂,根系发育差,叶片暗绿,新叶色淡而变形,花器发育不正常,生育期延长。常用的硼肥有硼砂和硼酸。硼肥可作基肥、追肥、种肥施用。在缺硼土壤上作基肥用时,每亩可施硼砂或硼酸0.5公斤～1.5公斤;作种肥浸种时浓度为0.01%～0.1%,拌种时平均每公斤种子用肥量为0.4公斤～1.0公斤;叶面喷施宜用0.1%～0.2%的硼砂或0.05%～0.1%硼酸溶液。
First, the lack of boron fertilizer boron plant stems in the stem thicker, brittle and easy to split, root development is poor, dark green leaves, the new leaf color light and deformed, floral development is not normal, the growth period is extended. Common boron fertilizers are borax and boric acid. Boron can be used as basal, top dressing, fertilizer application. When used as basal fertilizer on boron-deficient soil, bauxite or boric acid can be applied at a rate of 0.5 kg to 1.5 kg per acre. Concentration of 0.01% to 0.1% when soaked in seed fertilizer is 0.4 kg ~ 1.0 kg Kg; foliar spraying should use 0.1% ~ 0.2% borax or 0.05% ~ 0.1% boric acid solution.
