不同的营养元素在作物生长、发育和产量形成过程中,具有同等重要性和不可替代性,某种元素供应不足往往导致生理失调,表现缺素症,从而降低作物产量。虽在一定范围内,各元素间尚有一定的互补性,但严重缺乏时常成为产量进一步提高的限制因子,因而,微量元素同样是不可缺乏的。不 Different nutrient elements are equally important and irreplaceable in the process of crop growth, development and yield formation. Inadequate supply of a certain element often leads to physiological imbalances and deficiencies in performance, thus reducing crop yield. Although within a certain range, there is a certain degree of complementarity between the various elements, but serious lack of often become the limiting factor to further improve the yield, therefore, trace elements are equally indispensable.
