This book is based on this background to carry out research, the occurrence characteristics of exogenous selenium and the aging model as the research object, combined with the action mechanism of salinized soil in arid areas. The first chapter of this book is the study of the influence mechanism of exogenous selenium on crops in arid regions, looking for crops in arid regions with strong selenium accumulation ability, and exploring the impact of exogenous selenium on crop yields in arid regions, in order to study the effect of exogenous selenium on increasing drought. Lay the foundation for the application of regional crop yields. The second chapter mainly introduces the analysis of salinized soil in arid areas. The problem of soil salinization is the main obstacle restricting the agricultural development in arid areas. It mainly analyzes the important factors that affect the stability of the oasis ecological environment. The third chapter is the study of soil selenium bioavailability, which mainly analyzes the influencing factors of soil selenium deficiency, insufficient selenium content in edible plants and crops. The fourth chapter is the analysis of the aging model of exogenous selenium in salinized soil in arid area. The fifth chapter mainly introduces the analysis of the assignment characteristics of exogenous selenium in arid areas and salinized soils. Chapter 6 analyzes the absorption mechanism of exogenous selenium in the soil.
