This study systematically collects surface soil and crop samples from four typical agricultural parks in Bijie City,and processes and analyzes the measured data,providing guidance for the development and utilization of selenium rich land and the development of selenium rich agriculture in Bijie City.The results show that the average selenium content in the soil of the four agricultural parks reaches the selenium enrichment threshold(0.4 mg/kg)of the"Natural Selenium Enriched Land Delineation and Identification"(DZ/T 0380-2021),and soil type is an important factor affecting soil selenium content.Among the crops grown in the four agricultural parks,tea,rice,corn,and traditional Chinese medicine all have the potential to develop selenium rich agricultural products.
