- Abstract:
-
Based on field investigation and analysis in lab, the variation of physical properties and organic matter of soil under impacts of Caragana korshinskⅡ plantation with different ages in loess hilly region were studied in this paper. The results showed that as age grew, Caragana korshinskⅡ plantation could increase silt and clay proportions in soil but lower the bulk density (except 50 years old plantation), besides, improve the soil porosity, promote positive development of the soil. In the aging process of Caragana korshinskⅡ plantation, the content of water stable aggregate>5 mm gradually increased; the content of water stable aggregate>0.25 mm and organic matter declined at first, then increased. Caragana korshinskⅡ plantation had the most obvious improving effect on physical properties of top soil layer. But deeper the soil profile was, the weaker the effect was.
