Abstract
[Objective] To study effects of the basic conditions of the purple soil on soil selenium in Jiangjin district of Chongqing City.[Method] Using soil selenium in Jiangjin district in Chongqing agricultural soil as the main research object,soil basic properties in the region and different forms of selenium content in soil were analyzed,and effects of soil conditions on content of water solulde seleinum,Olsen selenicum in the soil were discussed.[Result] The total selenium,water soluble selenium,Olsen selenium in purple soil were closely related to the basic properties of the soil.Total selenium had extremely significant negative correlation with water-seluble selenium,and total selenium was significantly positively correlated with Olsen selenium;Selenium content in the soil had a certain relationship with the parent material,but was also affected by exogenous factors;Soil pH and total selenium,water soluble selenium,01sen selenium showed extremely significant positive correlations,and in acidic soil selenium content was relatively large;With the increase of organic matter content,total selenium and water soluble selenium content increased gradually,while Olsen selenium content gradually reduced.[Conclusion] The study provides theoretical basis for adjusting the selenium content in soil,improving plant selenium nutrition and prevention and control of selenium reaction disease.关键词
