利用4株分离自云南石漠化地区豆科植物的根瘤菌，接种于播种8个月的红三叶的盆栽苗（基质为石漠化土壤），测定根瘤菌对石漠化土壤的理化性质和红三叶的生长指标的影响、植株结瘤情况。结果表明，4株供试根瘤菌能改善土壤的理化性质，降低石漠化土壤的pH值，明显提高土壤的有机质、 N、 P、 K、 Ca、 Mg等营养元素的含量；4株供试根瘤菌能提高红三叶的生长特性，增加其相对叶绿素含量和生物量，促进根系的生长，改善红三叶的结瘤情况，增加结瘤数量及根瘤的质量。红三叶生长周期短，根系发达，抗逆性强，是石漠化植被恢复治理的优良草种。

Study on ecological effect of 4 leguminous Rhizobia in rocky desertification ecological system by pot exper -iment was conducted .The results showed that the 4 Rhizobia could improve soil physical and chemical properties of rocky desertification .Soil pH value was significantly reduced with obviously increase soil organic matter , such as N, P, K, Ca and Mg nutrients content .The 4 Rhizobia could improve the growth characteristic , relative chlorophyll content , and biomass of Trifolium pretense, and then promote root growth , improve nodular situation , increase the quantity and the quality of the nodule .Trifolium pretense could be widely applied in rocky desertification governance in the process of vegetation restoration with its short growth cycle , developed root system and strong resistance .
