高镉地质背景区土壤中镉-硒相互作用的田间试验研究
摘要
Abstract
In this study,tobacco leaves,stems and soil samples were systematically collected from the tobacco growing area of Baguotun,Naguo Village,Jingxi City,Guangxi Zhuang Autonomous Region,and the contents of Cd and Se were determined respectively.The contents,migration and transformation of Cd and Se in soil and tobacco plants without Cd enrichment and enrichment were analyzed.The results showed that there may be antagonism between Cd and Se,and 0.14 mg/kg Se fertilizer is a better concentration,which has a good antagonistic effect on Cd.By analyzing the contents of cadmium and selenium in soil-tobacco leaves under different concentrations of Se fertilizer in typical tobacco planting areas,the migration and transformation rules of cadmium and selenium in soil-tobacco plants were studied,which provided data support for further inhibition of cadmium absorption by tobacco plants and rational application of selenium.关键词
