农田土壤硝酸盐淋失是导致地下水硝酸盐污染的主要原因，影响农田土壤中硝酸盐积累和淋失的因素很多，主要有施肥、降水、灌溉、土壤性质以及耕种制度等。 - Owing to less water evaporation and undeveloped wheat roots under zero tillage, it was easy to leaching of nitrate nitrogen below the soil depth of 100 cm. As a result, both the ratio of nitrogen utilization and the wheat yield decreased.
另外，由于免耕处理蒸发较小和小麦根系不发达，NO3&N淋失到土壤剖面的100cm以下，不仅使氮肥利用率低，也是造成免耕减产原因之一。 - But during the rice growth season, the nitrate content of the surface soil layer in soil profiles was lower than that of bottom soil layer. It was leaching phenomenon of nitrate.
但在水稻生长季节土壤剖面中表层土壤的NO3N含量低于底层的NO3N的含量，出现明显的淋溶现象。 - The results showed that the leaching loss of nitrate nitrogen in the soil was far more than that of phosphorous.
