Using wheat and fallow fields in the dry land in south part of Loess Plateau, as study object with establishing 6 kinds of treatments, the influence of cultivation measure and fertilizer condition change on different growth period on soil phosphatase activity and soil nitrous oxide (N2O) emission flux were studied. The cultivation layer soil phosphatase activity and N2O emission flux appeared negative relation markedly, with correlation coefficient of 0.4660. In the wheat growing stage, the soil N2O emissio...
