摘要
微量元素在土壤中的含量较少,但对植物的生命活动却不可或缺。微量元素的缺乏通常发生在植物新生部位的幼嫩组织,且该营养元素易被植物老叶片等组织所固定,很难被再次利用。通过对微量元素的认识,可以分清缺素都是植株矮小、缺绿黄化等通病,对指导技术人员从事植物的生产活动有着积极的意义。
There is little microelement in soil but it is important for plant active.Microelement was often lacked in the tender tissue of plant＇s fresh part and it is easy to be fixed by old leaves.The common fault of plant that is lack of microelement is low and yellow.This paper is of actively significance for technical personnel to direct production work.
