摘  要：
采用室内培养的方法,对尿素硝酸铵溶液(UAN)在不同土壤类型上的氨挥发特性进行了研究。结果表明:尿素及尿素硝酸铵溶液的氨挥发特性均同时受土壤类型及土壤水分状况影响。土壤相同水分条件下,尿素硝酸铵溶液在黑钙土、黑土、白浆土中的氨挥发速率和氨挥发累积量均低于等氮量的尿素,氨挥发累积量分别降低24. 7%、38. 2%、26. 3%。在黑土和黑钙土中尿素硝酸铵溶液的氨挥发损失情况表现为低含水量高于高含水量,氨挥发累积量分别高42. 5%和29. 7%,而在白浆土中,2种含水量的氨挥发累积量无明显差异;尿素硝酸铵溶液在3种类型土壤中的氨挥发速率及氨挥发累积量表现为黑钙土>黑土>白浆土。与尿素相比,尿素硝酸铵溶液在3种类型土壤中的氨挥发损失均相对较低,尤其在黑土和白浆土中表现更为明显。

摘  要：
Ammonia volatilization characteristics of urea ammonium nitrate solution of different soil types were researched by indoor constant temperature cultivating method. In this study,ammonia volatilization characteristics of urea and UAN were affected by soil types and moisture. The results showed that under the same soil moisture,ammonia volatilization rate and accumulation of UAN were lower than that of urea of equal nitrogen amount in chernozem,black soil and albic soil. Ammonia volatilization accumulation decreased by 24. 7%,38. 2% and 26. 3%,respectively. In black soil and chernozem,ammonia volatilization accumulation of UAN with low field water capacity treatment was higher than that with high field water capacity treatment,which increased by 42. 5% and29. 7%,respectively. But there was no significant difference in albic soil. Ammonia volatilization rate and accumulation of UAN in three different types of soil showed an order of chernozem >blacksoil>albic soil. Compared with urea,ammonia volatilization loss of UAN was lower in three kinds of soil types,especially in black soil and albic soil.
