摘 要：This study was carried out to investigate the properties of soil and water under Double-cropping SSH followed by whole crop barley(SSFWB) or by Hairy vetch(SSFHV) in paddy land.A field study was conducted at Baeksan-myeon,Kimje,Jeonbuk province in Korea on clay loam soil for 3 *** plots were arranged in completely randomized design with three *** pH and the contents of T-N and organic matter (OM) in soil samples collected at the end of the experiment were remarkably higher than those at the beginning of the experiment in both SSFWB and SSFHV treatment(P0.05).The contents of an exchangeable cations at the end of the experiment were remarkably higher than those at the beginning of the experiment in both SSFWB and SSFHV (P0.05).And then,the concentration of NO-N,NH-N and PO-P in discharge and leaching water were not influenced by the cropping system
