| Abstract;In the Hetao irrigation district, soil salinization and water shortage have been occurring. To study the effect of traditional desalinization techniques, we set up experimental sites near Shahaoqu station and started soil improvement since 1994. The techniques emplyed were mixing organic materials in soil and ponding irrigation in autumn(leaching). This paper reports the results of annual changes of soil chemical and physical properties at experimental sites. Mixing organic materials in soil did not improve soil physical properties, however EC values(soil surface and profile) were lowered by ponding irrigation in autumn. It was confirmed that soil desalinization can be done by ongoing desalinization techniques. (author abst.) |
