本研究旨在探讨土壤盐分积累对蒙古草原畜牧业生产的影响。在盐碱区和对照区，我们比较了土壤盐度、植物和羊毛中的钠浓度以及母羊的体重。高盐区土壤平均盐分、钠浓度和生长迟缓程度均高于对照区。羊毛样品中钠潴留增加是饮食中钠过量的证据。这些结果反映了钠通过植物从土壤溢出到羊，这种溢出会降低盐碱区的牲畜生产力。
The aim of this study was to examine the effects of accumulated soil salt on livestock production in Mongolian grasslands. In saline and control areas, we compared soil salinity, sodium concentrations in plants and wool, and body weights of ewes. Mean soil salinity, sodium concentrations, and growth retardation were greater in the high-salinity area than in the control region. Increased retention of sodium in wool samples was evidence of excess dietary sodium. These results reflect sodium overflow from soil to sheep via plants, and this overflow can diminish livestock productivity in saline areas.
