土壤理化条件变化对含硫气体释放的影响

The Influences of Physico chemical Factors on the Emission of Volatile Sulfur Gases from Soil

研究在不同的室内培养条件下，土壤的各种物理化学条件对含硫气体释放的影响．结果表明，土壤在含水率为５０％ ～７５％ ，ｐＨ＝ ３．２５～８．６２，较大的ＣｖＮ 条件下，各含硫气体的释放量较大．而光照条件对于不同的硫源释放含硫气体的情况各有不同．

In this paper,the influences of physico chemical factors on the emissions of volatile sulfur gases from soil were investigated under different incubation conditions.The results showed that under 50%～75% of water content,pH=3.25～8.62,more ration of organic carbon and nitrogen,sulfur gases emitted more;and under different light,emission was different from different sulfur sources.It was concluded that the reason of different emission was that environmental condition changed the amount of sulfur emission by changing activities of the microbes.
