本文论述了土壤中氨挥发损失的重要性及氨挥发损失的机理、深入系统的研究了各个环境因子(温度、水分、表面气流速率、NH_4~+浓度、肥料种类、施肥方式)和各个土壤特性(土壤PH、阳离子代换量、土壤质地、尿酶活性)对氨挥发损失的影响和它们之间的相互关系,并对土壤特性之间的相关性和多个土壤特性共同对氨挥发的影响进行了初步探讨,为防止土壤氨挥发损失,提高N肥利用率、指明了防止氨挥发损失的途径和研究的方法。 In this paper, the importance of ammonia volatilization in soil and the mechanism of ammonia volatilization loss are discussed. The effects of various environmental factors (temperature, moisture, surface air velocity, NH 4 + concentration, type of fertilizer, fertilization mode) and soil characteristics (Soil pH, cation exchange capacity, soil texture and urease activity) on the ammonia volatilization loss and their correlation, and the correlation between soil characteristics and multiple soil properties on ammonia volatilization In order to prevent the loss of soil ammonia volatilization and improve the N fertilizer use efficiency, we pointed out the ways to prevent the ammonia volatilization loss and the research methods.
