| 摘 要： | 通过盆栽试验,研究不同碳形态有机质(褐煤、锯末粉、面粉、小麦秸秆粉)对土壤氮磷流失的影响。结果表明,添加有机质能有效增加土壤全氮含量,而降低土壤有效氮含量,特别是添加小麦秸秆粉后,有效的减少了氮素的流失量,但却增加了磷的流失量。

| Abstract: | Effect of different carbon sources of organic matter(lignite,sawdust powder,flour,wheat straw powder) on the soil nitrogen and phosphorus loss were investigated by pot experiment.The results showed that the addition of organic matter can increase soil total nitrogen content,and decreased the content of available nitrogen in soil.In particular,it was effective reduction of the nitrogen loss,but increased the amount of phosphorus loss by addition wheat straw powder. |

| Keywords: | organic matter organic carbon nitrogen phosphorus losses wheat straw |
