氯化铵;硝化率;挥发量
摘  要：
本试验采用室内模拟的方法,探讨氯化铵在上海郊区三种主要土壤上的硝化、挥发农业化学(以下简称农化)特性。结果表明:氯化铵在不同土壤上的硝化率,挥发量均以夹沙泥最高,沟干泥次之,青紫泥最低,且硝化和挥发进程可用经验方程Y=A·T~B表示;氯化铵入土后具有较高的稳定性;氯化铵中氯离子能一定程度地抑制土壤硝化微生物的活性,与尿素混施可延缓尿素的硝化率。

摘  要：
In this experiment, imitation method was used in laboratory for investigating the agrochemical properties of nitrification and volatilization of ammonium chloride on three main kinds of soil in Shanghai suburbs. The result showed that the nitrification rate and volatilization ammounts of ammonium chloride on different soils may be ranked in following order: Jiasha-Ni (sandy loam paddy soil)>Gougan-Ni (a percolating paddy soil)>Qingzhi-Ni (water-logged paddy soil, which retained organic matter more than 3%). The processes of nitrification and volatilization may be simulated by the power function equation. Y= A·T~B. The ammonium chloride was possessed of rather good stability after it had been buried into the soil. The chlorine anion of ammonium chloride can inhibite the nitrification activity of soil microorganism to a certain degree, so that when it is mixed with urea, the nitrification rate of urea may be decreased.
