| Abstract: | In order to solve the water-logging problem of foreshore reclaimed land in wusi Farm, Shanghai, 2-years' field experiments were conducted. Results show that measures such as the control of water level in outlet channels and drainage by underground pipes have been very effective in water-loging control, desalinization and yield increase. The duration of water -logging for barley has been shortened to 3days. Soil salinity in 1.0 metre soil depth dropped to below 0. 15% from that of 0. 235% before the experiments. Yield of barley increased by over 20%. |
