| 摘 要： | 实验结果表明:西红柿、红麻、高梁和玉米作物之间对R_b与K吸收的相关系数为r=0.9842,各生育期对R_b与K吸收及分布的相关系数均在0.9以上,因此可以用R_b做K的示踪剂研究这些作物对钾的吸收。R_b与K在土壤中移动、分布的相关性受质地、水分状况影响较大,用R_b做示踪剂研究K在土壤中的移动要慎重。

| Abstract: | The results showed that, the correlation coefficient of ~(86)Rb and Kabsorpted by tomato, bluisdogbane, sorghum and corn Is 0,9842, At cachgrouwing ptriod of the crops above is around 0.9, Thus, it is suitable to study the absorption with ~(86)Rb instend of K. The corelation of movement in soil of ~(86)Rb and K is affected by the texture of soil and water condition Therefor, the careness is neededfor studing the movement of K with ~(86)Rb. |
