| 摘 要： | 通过海南典型4类胶园土壤对磷的等温吸附与解吸试验,结果表明:所有供试胶园土壤磷的等温吸附曲线与Langmuir方程都很吻合,其相关系数为0.9480**～0.9999**;胶园土壤磷最大吸附量(xm)在555～909 mg/kg之间,磷的吸附强度因子(K)差异很大,在0.09～1.71之间.当加入磷浓度较低时,土壤磷解吸量较少且土壤间差异小;当加入磷溶液浓度大于30mg/kg时,磷解吸量开始明显增大,土壤差异变大.

| Abstract: | Experiments for phosphate sorption and desorption on rubber tree plantation soils were carried out in Hainan.The results showed that the sorption data for all the soils sampled in the rubber plantations could be simulated well by Langmuir equation and that the correlation coefficient ranged from 0.948 0**to 0.999 9**.The maximum phosphate sorption(Xm) and sorption intensity factor(K) calculated by Langmuir equation varied from 555 mg/kg to 909 mg/kg,and 0.09 to 1.71,respectively.The phosphate desorption was... |
