中文摘要	以喀什地区泽普县荒漠河岸林土壤为研究对象,采用室内模拟方法,研究氮沉降对不同含水量土壤氮素矿化的影响,以期为新疆喀什荒漠区土壤氮素及水分合理施用提供理论依据。结果表明,氮沉降处理土壤矿质氮含量高于CK(不添加外源氮素的处理) ,培养7 d时,两处理土壤矿质氮含量均达到最大值。土壤含水量为40%时,氮沉降处理土壤净硝化速率最大;培养28 d时,土壤净硝化速率最大(土壤含水量为0的处理除外) 。土壤含水量为20%时,氮沉降处理土壤净矿化速率最大;培养7 d时,氮沉降处理土壤净矿化速率最大。
英文摘要	The effect of simulated nitrogen deposition on soil nitrogen mineralization was studied with desert riparian forest soil as material using indoor simulation method under different water conditions in Kashi area, so as to provide a basis for rational fertilization and irrigation in the research area. The results showed that soil mineral nitrogen content of nitrogen deposition treatment was greater than that of CK without nitrogen deposition,mineral nitrogen contents of the above two treatments reached maximum when the soil was cultured for 7 d. The soil net nitrification rate of nitrogen deposition treatment reached maximum when the soil moisture content was 40%; the soil net nitrification rate of nitrogen deposition treatment reached maximum(except the treatment with soil moisture content of 0) when the soil was cultured for 28 d. When the soil moisture content was 20%, the net mineralization rate of nitrogen deposition treatment reached maximum; the net mineralization rate of nitrogen deposition treatment reached maximum when the soil was cultured for 7 d.
