| 摘 要： | 研究了海南14个胶园土壤表面电荷特性与主要影响因子之间的关系.结果表明:①供试胶园土壤负电荷总量(CEC8.2)介于3.81～15.66 cmol/kg;永久负电荷量(CECP)介于0.82～9.82 cmol/kg之间 ,可变负电荷t(CECv)介于0.88～13.09 cmol/kg之间:可变负电荷量占表面负电荷总量的比例介于12.27%～88.00%之间,平均值60.64%.土壤的阴离子交换量(AEC)为0.45～3.46 cmollkg.②胶园土壤表面负电荷总量及可变负电荷量均是玄武岩发育的胶园土壤>砂页岩>花岗岩>变质岩>浅海沉积物;胶园土壤表面阴离子交换量(AEC)是玄武岩母质发育而成的胶园土壤>浅海沉积物>变质岩>花岗岩>砂页岩;③影响胶园土壤表面负电荷含量的主要因子是土壤有机质含量,而影响胶园土壤表面正电荷量的主要因素是土壤中游离铁含量.

| Abstract: | Soils from 14 rubber plantations in Hainan Province were collected to investigate their surface charge properties and their relationship with the major influencing factors. The amount of negative charge (CEC8.2) of the rubber plantation soils ranged from 3.81 cmol/kg to 15.66 cmol/kg, the amount of permanent negative charge (CECP) from 0.82 cmol/kg to 9.82 cmol/kg, the amount of variable negative charge (CECv) from 0.88 cmol/kg to 13.09 cmol/kg, and the anion exchange capacity ( AEC) from 0.45 to 3.46 cmol/... |
