【摘要】 用我国六种不同土壤研究了土壤农化特性对春小麦吸收⁹⁰Sr的影响。证实了土壤pH和代换性钙含量对^9OSr从土壤进入小麦植株有显著的影响。随土壤种类的变化,小麦对⁹⁰Sr的吸收及浓集系数均变动在1—7倍范围内。更多还原

【Abstract】 Absorbing fission products from soil is one source of crop contamination from radioactivities. The activity of fission products in soil changes with types of soil. This experiment studied the effect of agrochemical properties of soil on absorption of 90Sr by-spring wheat using six types of soil. The result showed that amount of exchangable calcium and pH value are significantly negative correlated with amount of 90Sr uptaken by wheat plant. The differences between six types of soil are 1-6 times in amount of 90Sr absorbed and concentration coefficient in wheat plant. The concentration coefficient in wheat seed varied in the range of 0.08 to 0.59.更多还原
