主要谷类粮食作物富硒研究概述

Overview of Research on Selenium Enrichment in Main Grain Crops

硒元素对人和动植物都十分重要,其摄入过量或缺少都会有一定的危害。人和动物可以从植物中摄取硒元素。着重选取近年来水稻、玉米、小麦具有代表性的富硒研究成果进行总结分析,结果表明:对作物适度施硒,不仅可以间接保证人体对硒元素的需求,还可以增加作物产量、提高作物品质和籽粒饱满度、减少作物对重金属元素的吸收,硒与某些中微量元素搭配施用可相互促进吸收。通过综合分析,为人们关注和合理补充硒元素,也为贫硒缺硒、重金属含量较高地区的作物种植提供参考。

Selenium is very important to humans,animals,and plants.However,excessive or inadequate supplementation may pose certain risks.Both humans and animals can acquire selenium through plant consumption.Therefore,this paper primarily presents a summary of recent research findings on selenium-enriched crops such as rice,corn,and wheat.The appropriate application of selenium fertilizer not only indirectly fulfills the human body's selenium requirements but also enhances crop yield,improves crop quality and grain plumpness while reducing heavy metals absorption by crops.Furthermore,when combined with specific trace elements,fertilization can facilitate mutual absorption.Through a comprehensive analysis presented in this paper,it aims to provide guidance for individuals to pay attention to and adequately supplement selenium while serving as a reference for crop cultivation in regions characterized by low selenium levels and high heavy metals content.
