Abstract:
      Through soil and plant survey in the sampling site and determination for soil physical and chemical properties,soil properties under the desert vegetation in Aral irrigated area were studied.The result showed that sand content was the highest in the particle composition,accumulation of organic matter in topsoil was very clear,soil nitrogen and phosphorus content was relatively low,soil potassium content was relatively high,and soil pH showed alkaline reaction. According to the Chinese Soil Taxonomy(3rd edition),the soils tested belonged to 3 soil classes,3 subclasses,3 great soil groups and 4 subgroups.That is to say,T-01 belonged to Mollic Hapli-Udic Cambosols,T-02 belonged to Calcaric Aridi-Orthic Primosols,T-03 belonged to Mottlic Hapli-Udic Cambosols,and T-04 belonged to Umbric Hapli-Orthic Gleyosols.
