| Abstract: | The article investigates and analyzes the content of organic matter and cationic exchange of upper and under layer of soil planting vegetable of 14 villages in Chenggong county. The average contents of organic matter of the upper layer and under layer of the soil are 3.23% and 1.87% respectively. The average contents of cationic exchange are 9.64 cmol/kg and 8.83 cmol/kg respectively. There is distinct positive correlation relation of the content between organic matter and cationic exchange. The changing trend of soil fertility is decrease from the west to the east. The upper layer reaches the grade of fertility, and under layer is light grade and middle grade of leanness. |
