摘  要:
以自然植被下土壤为对照 ,通过对芨芨草地土壤全氮、全磷、全钾、速效磷、钾、土壤有机质及阳离子交换量的测定 ,了解芨芨草对土壤养分的影响。结果表明 ,芨芨草对土壤有机质及全量养分影响不大 ,但能明显提高土壤速效养分的含量 ,并能提高土壤阳离子代换量及降低土壤 p H值

摘  要:
Taking the soil under the natural vegetation as a contrast, the Ji Ji grass' influence on soil nutrient was studied through the determination of nitrogen, phosphorus, potassium, quick acting potassium, phosphorus, soil organic matter and cation exchange capacity in the soil of Ji Ji grassland. The result shows that Ji Ji grass has little influence on soil organic matter and nutrient, but it can improve the quick acting nutrient content of the soil. At the same time, it can raise the cation exchange capacity and reduce the pH of soil.
