- Abstract:
-
It is very meaningful to understand the effect of contour hedgerow intercropping and ephemeral gully on spatial and temporal distribution of slopeland soil moisture in hilly red soil region.Soil water content of a depth of 45 cm at 15cm intervals along with soil and water losses were analyzed and the reasons for these changes were discussed based on soil water content measurement from late May to early November in 2007.The results showed that,soil moisture of 3 soil layers are gradually decreased during the rainy season,soil moisture along the vertical gradually increased during the dry season,and the mean variation of soil moisture in control treatment is weaker than that of Vetiver (Vetiveria zizanioides) treatment.For Vetiver treatment,soil water contents decrease at beginning,then increase or keep flat from its top to the bottom along longitudinal direction; for control treatment,soil water contents increase at beginning then decrease until keep increase.Vetiver increased variability of soil moisture along horizontal direction to agreat extent,but longitudinal direction still has more influence on soil moisture than horizontal direction.
