施用亞硒酸鹽和硒酸鹽（土施或葉面噴施）對土壤中硒的轉運，轉化和分布及其對小麥（Triticum aestivum L.）
發(fā)布時間：2022-01-10 15:14
硒（Se）是環(huán)境和生物學研究中重要的微量元素。過去幾十年來,人們對硒對人類和動物健康的重要性進行了廣泛的研究,并討論了它們可能在植物代謝中的作用,但它們對植物的重要性仍然存在爭議。飲食是人類硒攝入的主要途徑,作物硒的生物強化已經被證明可以增加普通食物中的硒含量,從而增強人類的營養(yǎng)。硒生物強化是一項農藝措施,通過植物育種,基因工程或施用硒肥如硒酸鹽和亞硒酸鹽等增加作物中硒的積累。小麥在生產富硒的食物增加人類的硒攝入量中起著重要的作用,因此全面了解土壤-植物系統(tǒng)中的硒以及它的循環(huán)是非常必要的。為此,我們進行了一系列盆栽試驗和田間試驗以評估小麥中硒的分布,轉運,積累和生物有效性。通過對不同小麥品種進行不同施硒水平、施硒種類（硒酸鹽和亞硒酸鹽）與不同施硒方式（土施或葉面噴施）的試驗。得到的主要觀點和結果如下。1)研究了硒酸鹽和亞硒酸鹽對土壤中硒元素的分布,轉化的影響以及硒對小麥各部位的積累和有效性的影響。使用不同濃度的外源亞硒酸鹽或硒酸鹽(0.5,1,2.5,5和10mg kg-1含硒土壤)進行盆栽實驗。采用連續(xù)浸提法測定土壤中硒的形態(tài),并用不同模型研究硒在土壤中的轉化及...
