油菜是对硼最敏感的作物之一,特别是甘蓝型油菜对缺棚最敏感,需硼量最大,在缺硼土壤和潜在性缺硼土壤种植油菜,其根、茎、叶、花、蕾、果都不能正常生长发育,尤其是苗后期和开花结角期气候干旱会加重缺硼和花而不实的程度,导致菜子产量明显降低。因此,在缺硼土壤和潜在性缺硼土壤及在干旱地区和干旱季节应当特别重视施用硼肥。
Rape is one of the most sensitive crops to boron. In particular, Brassica napus is the most sensitive to the shortage of canopy, the largest amount of boron needed, planting roots, stems, leaves, flowers, buds in boron-deficient soils and potentially boron-deficient soils , Fruit are not normal growth and development, especially in late seedling and flowering knot climate drought will increase the lack of boron and flowers and the degree of false, resulting in significantly reduced yield of colza. Therefore, special attention should be given to the use of boron fertilizers in boron-deficient and potentially boron-deficient soils and in arid and dry seasons.
