施用亚硒酸盐和硒酸盐（土施或叶面喷施）对土壤中硒的转运，转化和分布及其对小麦（Triticum aestivum L.）
发布时间：2022-01-10 15:14
硒（Se）是环境和生物学研究中重要的微量元素。过去几十年来,人们对硒对人类和动物健康的重要性进行了广泛的研究,并讨论了它们可能在植物代谢中的作用,但它们对植物的重要性仍然存在争议。饮食是人类硒摄入的主要途径,作物硒的生物强化已经被证明可以增加普通食物中的硒含量,从而增强人类的营养。硒生物强化是一项农艺措施,通过植物育种,基因工程或施用硒肥如硒酸盐和亚硒酸盐等增加作物中硒的积累。小麦在生产富硒的食物增加人类的硒摄入量中起着重要的作用,因此全面了解土壤-植物系统中的硒以及它的循环是非常必要的。为此,我们进行了一系列盆栽试验和田间试验以评估小麦中硒的分布,转运,积累和生物有效性。通过对不同小麦品种进行不同施硒水平、施硒种类（硒酸盐和亚硒酸盐）与不同施硒方式（土施或叶面喷施）的试验。得到的主要观点和结果如下。1)研究了硒酸盐和亚硒酸盐对土壤中硒元素的分布,转化的影响以及硒对小麦各部位的积累和有效性的影响。使用不同浓度的外源亚硒酸盐或硒酸盐(0.5,1,2.5,5和10mg kg-1含硒土壤)进行盆栽实验。采用连续浸提法测定土壤中硒的形态,并用不同模型研究硒在土壤中的转化及...
