Effects of Iron Slag Adding on Water Nutrient Dynamics in Paddy Fields
摘要
Abstract
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.关键词
