Based on nitrogen concentrations of different forms, total phosphorus and soluble phosphorus in the surface water, nitrogen and phosphorus pollution sources were further explored by means of a field undisturbed tension-free monolith lysimeter(1 m2 in area and 1 m in depth)in combination with the 15N-tracing method.

随着工农业生产的快速发展，人口的急剧增加和化学肥料使用量的增加以及生活污水的直接排放，河流、湖泊等地表水体的氮磷污染有加重趋势，如北方的辽河、汾河、海河及淮河，南方的黄浦江、太湖、巢湖、滇池等都遭受严重污染[1￣3]。

Where the irrigating frequency was 1 or more than 1 every four days, it did not remarkably affect the ET of potato; but where the irrigating frequency was 1 every six days or 1 every eight days, the ET of potato measured by a lysimeter was obviously higher than what it was in the treatment with a higher irrigating frequency.

大于或等于1次/4 d滴灌灌水频率对马铃薯的腾发量影响不明显；但当滴灌灌水频率为1次/6 d或1次/8 d时，由蒸渗仪测得的马铃薯腾发量明显低于更高频率处理。
