| 摘 要： | 为研究硝态氮在宁夏黄灌区灌於土中的基本运移规律,采用水平土柱进行硝态氮水平运移规律研究,并采用自制垂直土柱完成了硝态氮垂直运移规律研究.硝态氮水平运移规律研究表明:硝态氮运移与水分湿润峰迁移具有很好的一致性,随着硝态氮运移距离的增加,硝态氮浓度升高,并在湿润峰处累积；硝态氮浓度随含水量的增加而减少,并呈幂函数关系；硝态...

| Abstract: | Nitrate nitrogen(NO-3-N) transport has special patterns in anthropogenic-alluvial soil of Ningxia irrigation area.In this paper,we studied the NO-3-N transport characteristics using the horizontal and vertical soil columns.The results on NO-3-N horizontal transport experiment indicated that the NO-3-N horizontal transport followed very well with the soil moisture movement.With the increases of NO-3-N horizontal transport distance,the concentration of NO-3-N was higher,and reached the maximum at the interfac... |
