| Abstract: | The soil alkai-hydrolyzable nitrogen(SAN) and total nitrogen(STN),available phosphorus(SAP) and total phosphorus(STP),available potassium(SAK) and total potassium(STK)in spring wheat field after two years of regulated deficit irrigation(RDI) were studied in Hexi oasis irrigation region,as well as the differences analysis in soil nutrients between 2003 and 2004 experimental years,aiming at providing some useful gist for the study on effects of RDI on soil nutrients in spring wheat field in this region. |
