油菜对微量元素的需要量极少,但不可缺少,也不能相互代替,尤其是硼锰等,多属酶、辅酶和一些维生素的组成部分,它们与光合作用和碳水化合物的运转和积累都有密切关系,如果供给不足,油菜植株中的叶绿素减少,产生失绿现象,削弱光合作用。还参与氮素代谢,并促进磷及其他矿质养份的功能,有助于保持养份平衡,有助于产量和质量的提高,增加含油量。
Rape on the trace elements in the minimal, but indispensable, can not replace each other, especially boron and manganese, mostly enzymes, coenzymes and some vitamins, and their photosynthesis and carbohydrate operation and accumulation have Closely related, if the supply is insufficient, the chlorophyll in the rape plants is reduced, resulting in the chlorosis phenomenon and the weakened photosynthesis. It also participates in nitrogen metabolism and promotes the function of phosphorus and other mineral nutrients, helps maintain the balance of nutrients, contributes to the increase of yield and quality, and increases the oil content.
