摘要:
根据在江苏省扬州市沿运灌区开展的一项大田观测试验,研究了稻田控制排水对浅层地下水中氮素的影响。结果发现,与常规排水相比,控制排水稻田浅层土壤排水中的铵态氮(NH+4-N)平均质量浓度有所降低,但硝态氮(NO-3-N)质量浓度则有所升高,二者变幅几乎相等; 施肥后NH+4-N的变化较NO-3-N的变化更为剧烈,高浓度过程更为短暂。因此控制排水对于氮素浓度的影响有限,其减排效果主要是对排水量的削减。
Abstract:
According to a field observation experiment carried out in the Yanyun Irrigation Area of Yangzhou City, Jiangsu Province, the effect of drainage control measures on nitrogen concentration in shallow groundwater of paddy field was studied. The results showed that compared with conventional drainage, the average mass concentration of ammonium nitrogen(NH+4-N)in the shallow soil drainage of the controlled drainage paddy field decreased, while the mass concentration of nitrate nitrogen(NO-3-N)increased, and the variation was almost the same. After fertilization, the change of NH+4-N was more intense than that of NO-3-N, and the process of high concentration was shorter. Therefore, the effect of controlled drainage on nitrogen concentration was limited, and its emission reduction effect was mainly on the reduction of drainage.
