冬季作物中,十字花科作物占比重较大,如白菜、甘蓝、萝卜、油菜等,这些作物和芹菜、麦类、胡萝卜等对硼都比较敏感。缺硼不仅作物的生殖生长受到严重影响,而且营养生长受阻,抗寒能力下降,还易诱发心腐病。那么如何补硼呢?施用方法如下:作基肥:硼肥在中度或严重缺硼的泥土上基施效果最好;每亩可用1~1.5斤硼砂与干细土或有机肥料混匀后开沟条施或穴施;或与氮、磷、钾等肥料混匀后一起基施;切忌使硼 Winter crops, cruciferous crops account for a larger proportion, such as cabbage, cabbage, radish, rape, etc., these crops and celery, wheat, carrots, etc. are more sensitive to boron. Boron deficiency not only reproductive growth of crops severely affected, but also blocked vegetative growth, decreased ability to cold, but also easy to induce heart rot. So how to make boron? Application as follows: as a base: boron fertilizer in medium or severe lack of boron on the best infrastructure facilities; available per acre 1 to 1.5 kg of borax and fine dry or organic fertilizer mixed open Gou Shi facilities or points Shi; or with nitrogen, phosphorus, potassium and other fertilizer together after the foundation facilities; avoid boron
