施用硼肥可促进油菜增产,特别是缺硼严重的土壤施用硼肥,增产更加显著,多年的实践证明,少则增产20%,多则增产30%以上。硼肥的施用方法有基施、叶面喷施、浇施、种子处理和配合施用等。当前各地销售的硼肥主要有硼砂、硼酸等,但以硼砂为主。1.基施在油菜播种或移栽前将硼肥施入土壤中,有利于满足油菜全生育期对硼素的需要。基施不仅肥效长,且节约用工,在严重缺硼土壤,增产效果尤为显著。每亩(1亩=667平方米,下同)用
Application of boron fertilizer can promote rapeseed production, especially boron deficiency in the application of boron fertilizers, more significant increase in production, many years of practice has proved that, at least 20% increase, while more than 30% increase in production. Boron fertilizer application methods basal, foliar spray, pouring, seed treatment and application of such applications. The current sales of boron fertilizer are mainly borax, boric acid, etc., but mainly borax. 1. Kashi facilities in the rapeseed or transplanted before the application of boron fertilizer into the soil, is conducive to meet the rape growth period boron needs. Basal fertilizer not only effective, and save labor, in a serious lack of boron soil, yield-increasing effect is particularly significant. Per acre (1 mu = 667 square meters, the same below) use
