植物锌营养研究综述与展望

The Review and Prospect of Plant Zinc Nutrition

就国内外有关土壤锌的含量与化学行为，植物体对锌的吸收，锌的生理功能，土壤和植物体内锌与其它元素间的关系，锌营养的遗传差异，根际和根系分泌物与土壤锌之间的关系等方面的研究现状以及展望进行了综述。

Early in 1912,It was found that Zinc fertilizer is effective to correct the chlorlsis symptom in crops such as maize. Until 1926,Sommer and Lipman gave evidence that Zinc is an essential element for higher plant by doing experiments on sunflower and barley. Since then,the understanding of the nutritive function of zinc has been developed more and more. the fact of the chlorosis symptom of zinc deiciency in crops has been observed by soil scientist, plant nutrition scientist,agronomist, plant physiologist and phytopathologist. And they have done a series of studies in many fields such as zinc content in soils and its chemical actions,Zinc absorption by plant; the functions of zinc in physiological processes,the interctions between zinc and other nutrients and genotypic variation in zinc nutrition,and so on. This is a thesis of an overview on recent advances and prospect in these fields.
