硒是盐碱、贫瘠土壤中富含的无机物,植物吸收后富集在食物中对人和动物构成危害。美国科学家G.S.Banuelos 正在寻找一种“吃硒”植物,这种植物能抗盐碱、贫瘠,阻止或清除土壤中硒的有害富集。他从200多种已知的喜硒植物中选出了一种最好的植物—来自巴基斯坦的野生芥子。将其幼苗栽培在温室内含有大量硒盐的土壤里(3.5毫克/1000克土,相当于美国最富硒地区土壤中的剂量),芥子就轻易吸收了60%的硒而不表现过量。而一般喜硒植物。如羊茅,仅能吸 Selenium is an inorganic substance that is rich in salt and alkalis and poor soil. After being absorbed by plants, the plants are enriched in food and endanger humans and animals. G.S. Benuelos, a U.S. scientist, is looking for a “selenium-rich” plant that is resistant to salinity, infertility, deterring or eliminating the harmful enrichment of selenium in soils. He selected one of the best of 200 known Se-like plants - wild mustard from Pakistan. Planting its seedlings in soils containing large amounts of selenium salts in the greenhouse (3.5 mg / 1000 g soil, equivalent to the amount of soil in the US selenium-rich area), mustard readily absorbs 60% selenium without overdosing. The general hi selenium plants. Such as fescue, can only suck
