| 摘 要： | 通过盆钵和田间试验,研究了表面分子膜对水体氨挥发的影响。结果表明,表面分子膜可有效抑制氨的挥发,但抑制效果跟分子膜用量有关。Ｌｏｇｉｓｔｉｃ模型可以很好模拟预测盆钵试验中的氨挥发过程,通过修正氨挥发速率常数ｃ,可较好地模拟田间氨挥发过程。

| Abstract: | Pans and field experiments were conducted to investigate the effect of surface film on ammonia volatilization from water. Results showed that surface film could reduce ammonia volatilization significantly, but the effect was correlative to the addition rate of surface film. Logistic model was introduced to simulate the process of ammonia volatilization with surface film applied. Combined with modified parameter c, ammonia volatilization was fitted well by the model. |
