摘　　要：硒(Se)作为一种重要的微量元素,对作物的生长、营养品质以及人类健康具有显著影响,因此了解其在土壤中的分布特征至关重要。本研究旨在探讨陇南市两当县农用地土壤中硒的分布特征及其利用前景。通过对两当县不同区域土壤样本的采集与分析,结果表明该地区土壤中硒含量及有效硒含量与土壤pH值和有机质含量之间无明显相关性,杨店乡豆坪村、鱼池乡乔河村及太阳乡前川村的硒含量只达到足硒标准,无法用于天然富硒农产品开发,可通过人工施肥来使农产品富含硒元素。Selenium(Se),as an important trace element,has a significant impact on crop growth,nutritional quality and human health,so it is crucial to understand its distribution characteristics in soil.This study aimed to explore the distribution characteristics and utilization prospects of selenium in agricultural land soil in Liangdang County,Longnan City.Through the collection and analysis of soil samples from different areas in Liangdang County,the results show that there is no obvious correlation between the selenium content and available selenium content in the soil in this area and the soil pH value and organic matter content.The selenium content in Doupingcoen Qiaohecun and Qianchuan Village of Taiyang Township only reaches the sufficient selenium standard and cannot be used for the development of natural selenium-rich agricultural products.Artificial fertilization can be used to make agricultural products rich in selenium.
