摘　　要：为了阐明铁炉渣施加对稻田水养分动态的影响,对福州平原稻田不同铁炉渣施加水平下稻田水养分动态进行测定与分析。结果表明:对照、处理一、处理二、处理三样地稻田表层水中磷酸盐含量分别为657.3,622.2,546.8,474.1μg/L;铵氮含量分别为3.9,3.5,3.1,2.4mg/L;硫酸盐含量分别为82.8,69.1,66.0,69.6mg/L;溶解性有机碳含量分别为13.1,14.4,14.2,13.4mg/L。0-10cm土壤水中磷酸盐含量分别为135.4,141.7,161.1,201.4μg/L;铵氮含量分别为3.0,4.8,5.5,5.1mg/L;硫酸盐含量分别为84.6,59.1,81.6,70.6mg/L;溶解性有机碳含量分别为37.6,46.0,44.5,43.6mg/L。10-20cm土壤水中磷酸盐含量分别为68.6,100.3,113.8,141.6μg/L;铵氮含量分别为4.7,4.9,8.7,5.6mg/L;硫酸盐含量分别为81.9,75.1,62.8,60.0mg/L;溶解性有机碳含量分别为55.5,43.8,58.3,48.8mg/L。20-30cm土壤水中磷酸盐含量分别为138.0,156.1,166.6,188.6μg/L;铵氮含量分别为2.3,2.3,4.2,4.7mg/L;硫酸盐含量分别为78.6,61.5,70.2,73.3mg/L;溶解性有机碳含量分别为49.4,42.8,50.1,45.4mg/L。表层水中磷酸盐、铵氮和硫酸盐含量对照样地高于处理样地,0-30cm土壤水中磷酸盐、铵氮对照样地低于处理样地,硫酸盐含量高于处理样地,溶解性有机碳变化特征不明显。To clarify effects of iron slag adding on water nutrient dynamics in paddy fields,the water nutrient dynamics in Fuzhou plain paddy fields after adding different levels of iron slag were determined and analyzed.The results showed： Phosphorus content of surface water under control,and treatment one,treatment two and treatment three in paddy fields were 657.3,622.2,546.8,474.1 μg/L;ammonium nitrogen were 3.9,3.5,3.1,2.4 mg/L;sulfate were 82.8,69.1,66.0,69.6 mg/L;dissolved organic carbon were 13.1,14.4,14.2,13.4 mg/L.Phosphorus content of 0-10 cm porewater were 135.4,141.7,161.1,201.4 μg/L;ammonium nitrogen were 3.0,4.8,5.5,5.1 mg/L;sulfate were 84.6,59.1,81.6,70.6 mg/L;dissolved organic carbon were 37.6,46.0,44.5,43.6 mg/L.Phosphorus content of 10-20 cm soil water were 68.6,100.3,113.8,141.6 μg/L;ammonium nitrogen were 4.7,4.9,8.7,5.6 mg/L;sulfate were 81.9,75.1,62.8,60.0 mg/L;dissolved organic carbon were 55.5,43.8,58.3,48.8 mg/L.Phosphorus content of 20-30 cm soil water were 138.0,156.1,166.6,188.6 μg/L;ammonium nitrogen were 2.3,2.3,4.2,4.7 mg/L;sulfate were 78.6,61.5,70.2,73.3 mg/L;dissolved organic carbon were 49.4,42.8,50.1,45.4 mg/L.Phosphorus,ammonium nitrogen and sulfate content of surface water in control plot were higher than those of treatment plots,but phosphorus and ammonium nitrogen contents of 0-30 cm soil water in control plot were lower than that of treatment plots,and sulfate content was inverted,and dissolved organic carbon had not significant difference.
