冻融作用对土壤中氨氮的影响

Effects of Freezing and Thawing on the Content of Total Phosphor in Soil

我国对土壤冻融作用研究主要集中在自然环境条件下冻土环境变化。本文是对齐齐哈尔市南郊污水处理厂附近的氧化塘中的冻融土壤进行研究,论述了冻融作用对土壤中氨氮的影响。研究表明,季节性冻融作用对土壤氨氮有较大影响。

The research about the effect of freezing and thrawing of the soil was focused on the natural environment under the conditions of permafrost environmental change in our country.The research to freezing and thrawing soil in the oxidation pond near the southern suburbs of Qiqihar city sewage treatment plant was carried out The effects of freezing and thawing on the content of ammonia-nitrogen in soil were discussed.The studies showed that the content of ammonia-nitrogen in soil were influential by seasonal freezing and thrawing.
