摘要
土壤铁素由于有效性差,因而植物铁素营养失调现象是一个非常普遍的植物营养问题,本文对植物铁素营养的研究进展进行了述评,并对植物缺铁失绿的原因、缺铁症的诊断和矫正等进行了综述。
Iron is the first essential microelement for all higher plants which was detected by Griss in1843.It is used for chlorophyll formation as well as the functioning of various iron-containingenzymes in higher plants. Although abundant in most soils,most of these iron is not available fOrplant uptake.So,iron chlorosis is a world wide problem.The recent progress in study on iron nu-trition is reviewed in this paper.The causative factors, diagnostic practices and control measuresof iron deficiency in plants are also summarized.
