| 摘 要： | 针对不同母质砖红壤中氨的挥发损失进行了研究。结果表明,在施用等量的尿素条件下,不同母质的土壤氨挥发损失具有明显差异。在供试的6种土样中,尿素氨挥发损失率的顺序为:滨海沙土(17.37%)>浅海沉积物(11.31%)>紫色砂页岩(10.31%)>变质岩(5.95%)>花岗岩(3.11%)>玄武岩(1.25%)。氨挥发量的高峰从高到低的顺序为:紫色砂页岩>变质岩>浅海沉积物>滨海沙土>花岗岩>玄武岩。从总体上来说,不同母质砖红壤的pH值对氨挥发的量均有影响。

| Abstract: | Volatilization of ammonia from latosol soils with different matrixes was evaluated in the present study.The results indicate that the volatilization exhibited obvious differences,when urea as a fertilizer was applied with identical amounts.Of the six latosol soils studied,the volatilization rates were in a rank of : coast soil(17.37%)>neritic deposit(11.31%)>purple arenaceous shale(10.31%)>metamorphic rock(5.95%)>granite(3.11%)>basalt(1.25%;Losses of ammonia by volatilization were in an order: purple arenaceous shale>metamorphic rock>neritic deposit>coast soil>granite>basalt.In addition.In addition,pH value of the latosol soils from different matrixes affected the volatilization amounts of ammonia at a certain degree. |
