摘要

对昌平区保护地草莓土壤阳离子交换量进行统计分析,并探讨草莓土壤阳离子交换量与有机质、pH之间的关系。结果表明,土壤阳离子交换量的大小是多种因子共同制约的结果;目前昌平区保护地草莓土壤阳离子交换量平均值为14.9 cmol/kg,处于中等供肥能力水平;土壤阳离子交换量与有机质含量之间存在极显著正相关关系,提高土壤有机质含量能够有效增强土壤保肥性能。
        The cationic exchange capacity of strawberry soil in the protected area of Changping district was statistically analyzed, and the relationship between the cationic exchange capacity of strawberry soil, organic matter and pH was discussed. The results showed that the exchange capacity of soil cation was restricted by many factors. At present, the average cation exchange capacity of strawberry soil under protection in Changping district was 14.9 cmol/kg, which was at the level of medium fertilizer supply capacity. There was a significant positive correlation between soil cation exchange capacity and organic matter content. Improving soil organic matter content could effectively enchance soil fertility.
