摘  要：
过碳酰胺是一种新型精细化工品,也是一种新型氮肥,在国外已得到广泛的应用和开发,而我国对其开发和应用刚刚起步。试验研究了3种酸性土壤和3种碱性土壤施入过碳酰胺(和尿素对照)后的氨挥发特性。结果表明,过碳酰胺和尿素在供试6种土壤上的氨挥发强度具有相同的规律,都是先从小到大出现峰值,然后又降低;3种酸性土壤氨挥发高峰期约在第7 d左右,3种碱性土壤的氨挥发高峰期约在第3 d左右。土壤氨挥发含量的变化与pH变化同步。在最初挥发高峰期阶段,过碳酰胺的氨挥发强度在6种土壤上都大于尿素,但在供试的3种酸性土壤上,过碳酰胺的氨挥发总量均略小于尿素,而在供试的3种碱性土壤上,却正好相反。

摘  要：
Percarbamide is an important chemical product and a new fertilizer,widely using in foreign,but just beginning in china.Characteristic of ammonia volatilization of urea peroxide and urea in 3 acidic soils and 3 alkali soils were studied.The results indicated that ammonia volatilization intensity have the same tendency between urea peroxide and urea,and they followed the changes of soil pH: rose to maximum,and then fell in 6 soils with different maximum and different time.The maximum of ammonia volatilization intensity in 3 acidic soils and 3 alkali soils was the seventh day and the third day respectively;the initial ammonia volatilization intensity from urea peroxide was higher than that from urea in 6 soils,while the total ammonia volatilization quantity of urea peroxide were little smaller than urea in 3 acidic soils,and were little higher than urea in 3 alkali soils.
