Abstract Analysis on soil moisture in 0 - 100 cm soil layer in nonirrigated apple orchard in Weibei areas during March to October in 2003 and 2004 year showed that water content competition existed between herbage and apple in 0 -40 cm soil layer. But planting herbage had function of retain soil water content to 40 -80 cm soil layer. With different kind of herbage and different water consumption of different kind of herbage, the increasing and decrease of soil moisture storage was different in planting herbage areas, this occurred mainly in spring and in autumn. In the abundance of rainfall, planting herbage impacted less on soil moisture storage. But impacted more on soil water storage in the year of drought.
