摘要
研究了渗滤液灌溉土壤后，土壤含水率变化及矿物氮含量变化与粘壤土N2O释放的关系，结果表明：在含水率为25％时投加渗滤液的土壤样品N2O的释放通量是投加（NH4）2SO4溶液的2倍～3倍，当土壤含水率增加至40％时，N2O的释放通量明显增加。
It studies the relationship between changing of soil water content, mineral nitrogen content and the clay loam N2O releasing after the leachate irrigating the clay loam, results prove that, when the water content is 25 %, the N2O releasing amount of the soil sample auto-adding with leachate is 2 or 3 times of the soil sample auto-adding with （NH4）2SO4 solution, as the water content increasing to 40%, .the releasing amount of the N2O is always increased obviously.
