Abstract:
To understand the status of saline-alkali of new farmland，the typical saline-alkali land of Duiziliang town in Dingbian county of Shaanxi Province was surveyed，and the collected soil samples and water samples were analyzed in time.The new farmland survey results of Wangtanzi and Xiaotanzi and Baitugangzi villages in Duiziliang town showed:the 0-60 cm depth soil pH profiles were all higher and greater than 9;and the soil salinity of 0-60 cm depth soil profiles were increased gradually in order.The water of drainage ditches were alkaline water，and water salinity were ranged from 322 to 1 462 mg?L-1.Based on the status of saline-alkali new farmland of Duiziliang town and the successful experiences of soil improvement and salinity control of neighborhood regions，this study proposed the suitable saline-alkali soil improvement measures，e.g.soil tillage，soil surface cover，salinity barrier，chemical improvement，irrigation，and phytoremediation measures，and so on，in order to control and improve saline-alkali new farmland of Dingbian county.
