As part of the joint research conducted by Japan and China on the agricultural development of the Mu Us Shamo Desert, surveys on soil physical properties, moisture consumption, and the irrigation effect have been carried out on several plants in the fields of the Mu US Shamo Research Center since 1985. Using these results, schedules were established for the irrigation of a pilot farm which was constructed at the Research Center in 1991. The irrigation schedules were mainly based on the design guidelines of the Ministry of Agriculture, Forestry and Fisheries of Japan. As a result, the dimensions for the irrigation interval and water quantity per irrigation unit were estimated under the various plants in the pilot farm. From these design dimensions and the daily rainfall measured during the past 27 years, the net water requirement was estimated considering the effective rainfall. Also, the characteristics of the irrigation and rainfall could be explained by discussing the ratio of the total net water requirement to the total evapotranspiration, which subsequently indicates the factors in the pilot farm's future water management. Finally, in order to prevent the salinization of soils and groundwater and to select suitable irrigation methods, some recommendations are given for better use of technology in conservation management for the pilot farm.
