钼是植物体内不可缺少的微量元素之一.它能增加植物氮代谢有关的氧化还原酶的活性,提高植物体内蛋白质含量,并对植物细胞内核酸的形成提供良好条件.豆科作物根瘤菌的固氮作用,唯有在钼的参与下,才能完成其生理过程.它能提高固氮菌的固氮能力,并使硝态氮肥料变为可利用状态.它能提高叶绿素的稳定性,增强植物的抗病、抗旱和抗寒能力,促进植物生长发育,提早成熟.但是,钼不能代替氮、磷、钾三要素,而只能促进植物对这三要素的吸收.因此,在较高的施肥水平条件下,或在缺乏这三种元素的土壤上施用钼肥,增产效果相当显著.
Molybdenum is one of the essential trace elements in plants, which can increase the activity of plant nitrogen metabolism-related oxidoreductases, increase the protein content in plants and provide good conditions for the formation of nucleic acids in plant cells. Nitrogen fixation, only in the participation of molybdenum to complete its physiological processes.It can increase nitrogen fixation capacity of nitrogen-fixing bacteria, and nitrate nitrogen fertilizer becomes available.It can improve the stability of chlorophyll, enhance plant resistance However, molybdenum can not replace the three elements of nitrogen, phosphorus and potassium, but can only promote the plant’s absorption of these three elements.Therefore, under the condition of higher fertilization level Under or in the absence of these three elements of the soil on the application of molybdenum fertilizer, the yield is quite significant.
