| Abstract: | A field experiment was conducted in yellow earth and calcareous soil in karst mountainous region of Guizhou province. The result showed that ridge making of green manure, return of straws into soil and the combination of the two measures could enhance the accumulation of soil organic matter and nutrient availability to some extent. Because of the improvement of soil physical properties and fertility, the growth and development were better. Consequently, the annual average compound yield increased by 5.68 to 20.97% compared with the control. |
