Soil Moisture Characteristics under Hedgerow Intercropping System
Through the research on spatial change of soil moisture in different land use type.The results showed that: The first one was that there was negative correlation between the volume weight of soil and the soil moistare and the correlation coefficient was-0.095.The second one was that soil moisture change had medium variability in different soil layers.The third one was that soil moisture significantly changes( P > 0.05)with different land use type.The hedgerow(T3) without crops has the highest moisture(21.25)and the moisture of grassland was second high.The soil moisture of lands with hedgerow and crops and lands only with crops was the lowest.The forth one was that the field capacity of T2 declines with the depth decreasing.The field capacity of soils under other land use type declines between 0 and 40 cm depth and get the lowest in 40 cm depth,then it slowly decreases with the depth decreasing.
