摘要
研究了硫磺在旱地土和水稻土中的氧化特征。结果表明 :在培养 2 0～3 0d内硫磺的氧化速率最大 ,到 3 0d后基本达到稳定水平。在一定温度范围内 ,温度越高 ,氧化速率越大 ,3 0℃恒温条件下的氧化速率是 1 5℃恒温下的 2倍以上。湿润条件下的氧化速率比淹水条件下快近
This paper preliminarily studied the oxidational characteristics of elemental sulphur in upland soil and paddy soil through soil incubation experiment.The results showed that the oxidational rate of sulphur during 20～30 days' incubation was the highest on the whole,and the available sulphur content in soil approached to the peak after 30 days' incubation.The oxidational rate increased as the rise of temperature in some limited temperature range.The oxidational rate of sulphur under the condition of field moisture capacity was nearly two times of that under the condition of flooded soil.\;
