摘要
采用实验室模拟的方法研究了三峡库区受淹土壤的磷释放特征 ,结果表明 :随着浸泡时间增长 ,磷释放总量增加 ;在高水土比、高温。
The release properties of phosphorus from submarine soil of three-gorge reservoir district were studied through laboratory imitation. The results showed that the released quantity of phosphorus increased with submerge time going on. Larger water-soil ratio, higher temperature and weak acidity or weak alkalinity can accelerate the phosphorus release.
