| Abstract: | The contents of organic matter in purple soil are low in the Three Gorges Reservoir Region. After the contour hedgerow had been planted for five years, the contents of soil organic matter increased prominently. The HA/FA of humic acids added, the qualities of humic matters of the contour hedgerow of Leucaena leucocephala cv. salvador, Coriaria sinica and Vitex negundo raised, which resulted in the improvement of the granular structure of the soil in some degree. |
