摘要

为探讨稻田氮磷养分地表径流流失特征

以太湖地区典型稻田为研究对象

通过在溧阳、宜兴两地实施田间试验

对稻田施肥后田面水氮磷动态变化特征及径流流失进行了研究。结果表明:两试验点田面水总氮浓度均在施肥当日达到最高

然后迅速下降

基肥在施肥7 d后逐渐趋于稳定

而追肥则在施肥5 d后逐渐趋于稳定;田面水总磷浓度也是在施肥后的当日达到最高

而后迅速下降

8 d后基本趋于稳定;施肥后田面水总氮及总磷浓度与施肥天数均可用指数方程进行拟合

且均达极显著水平;溧阳和宜兴两试验点稻季总氮径流量分别为8.21

10.73 kg/hm2

分别占稻季氮肥总投入量的2.49%和3.25%

总磷径流量分别为0.58

0.75 kg/hm2

分别占稻季磷肥总投入量的0.97%和1.25%。

Abstract

In order to explore the characteristics of nitrogen and phosphorus runoff loss from paddy fields

the paper studied the rule of dynamic changes of TN and TP in surface water of paddy fields after fertilization and runoff loss from paddy fields by filed experiments conducted in Liyang and Yixing of Taihu region.The results showed that the concentration of TN in surface water both reached its maximum value at the first day after fertilization in the two field experiment sites

and then decreased rapidly.It desc...
