The Estimation of Soil Trace Elements Distribution and Soil-Plant- Animal Continuum in Relation to Trace Elements Status of Sheep in Huangcheng Area of Qilian Mountain Grassland, China

摘要

cqvip:The purpose of the present study was to survey contents of trace elements of Cu,Mn,Fe,and Zn in the surface layer(0-20 cm) in the soil,pasture and serum of sheep in Huangcheng area of Qilian mountain grassland,China.Also the soil-plantanimal continuum was analyzed.Soil(n=300),pasture(n=60),and blood serum samples from sheep(n=480) were collected from Huangcheng area of Qilian mountain grassland,China.The contents of trace element in the samples were analyzed by atomic absorption spectrophotometer after digestion.The soil trace elements density distribution shows a ladder-like pattern distribution.Equations developed in the present study for prediction of Fe(R2=0.943) and Zn(R2=0.882) had significant R2 values.
