| 摘 要： | 以淹水种植水稻为处理,以淹水不种水稻为对照,探讨植稻对模拟土柱(40 cm埋深处)渗漏液NO-3-N、NH4+-N淋出数量及在土壤中垂直分布的情况.结果表明,培养试验期间,种植水稻与不种水稻处理相比,种植水稻条件下NO-3-N流失远大于不种水稻处理,在土壤中的垂直分布也呈现相同趋势.而NH4+-N则与之相反.从绝对数量看,种植水稻与不种植水稻氮处理渗漏都以NO3--N为主.

| Abstract: | The purpose of this experiment was to research the leakage and distribution in soil of nitrogen in the condition of waterlogged rice growth.The results showed that there was more NO3—N losing under the condition of rice planting than without rice planting,and it was the same in its distribution in soil.But NH4+-N was reverse to NO3—N in the leakage anddistribution in soil.From the absolute quantity,no matter in rice planting or not,the main loss of nitrogen was NO-3-N. |
