| 摘 要： | 通过对高尔夫球场施用化肥后的降雨过程进行模拟淋滤试验，测试了不同施肥量、降雨强度及植被密度条件下硝酸盐的淋失浓度，并借助SAS9．0软件对测试数据进行了统计分析。结果表明，在降雨总量相同的条件下，淋滤出的硝酸盐氮受植被密度和施肥量的影响较大，而降雨强度则元显著影响；在暴雨-稀草-高肥时的硝酸盐氮淋出量最多，而中雨-密草-低肥淋出量最少。土壤中硝酸盐氮含量与淋滤液中硝酸盐氮的淋失量规律吻合，即硝酸盐氮淋失量大时，土壤中的硝酸盐氮含量低；而硝酸盐氮淋失量小时，土壤中的硝酸盐氮含量高。

| Abstract: | The experiment was carried out to test the leached concentration of NO-3-N after fertilization in the different conditions with golf course rainfall simulation,and analyze the data with SAS 9.0.The results suggested that NO-3-N concentration in the leachate was significantly effected by vegetation and dosage of fertilizer with the certain rainfall.But the rainfall intensity has no effect.The most NO-3-N content in the leachate was leached under the conditions of rainstorm,sparse turf and much fertilizer,and... |
