摘　　要：【目的】对广西大豆接种根瘤菌种植效果进行研究,为广西大豆生产推广接种根瘤菌提供依据。【方法】在广西宜州和都安大豆产区,以广西主推大豆品种桂春8号、桂夏3号和华南品种华春6号、华夏3号4个大豆品种进行接种根瘤菌种植试验,于苗期、分枝期、开花期、鼓粒期、成熟期取5株长势一致的大豆植株,调查其根瘤数、植株鲜重,并测产。【结果】不同试点的大豆品种接种根瘤菌后,其产量均较未接种根瘤菌的增产1.06%～8.74%,桂春8号在宜州点和都安点接种根瘤菌后较对照增产幅度比华春6号高;大豆接种根瘤菌后,不同品种和不同种植区域的大豆根瘤数均较对照增加,且大豆地上生物产量也增加。【结论】在广西大豆生产上通过接种根瘤菌来提高大豆产量是可行的,但各区域要选择合适的根瘤菌及与其适宜的大豆品种。[Objective]The effect of Rhizobium inoculation on the growth of soybean has been studied in order to provide foundation for popularization of Rhizobium inoculation technology for soybean production system.[Method]Four major soybean varieties,viz.,Guichun 8,Guixia 3,Huachun 6 and Huaxia 3 were planted after inoculation with Rhizobium in Yizhou and Du＇an areas of Guangxi.The quantity of Rhizobium and plant fresh weight were investigated at the seedling,branching,flowering,filling and maturity stages in five randomly plants and the yield was recorded at harvest.[Result]Rhizobium inoculation increased soybean yield in the range of 1.06-8.74%.This increase was higher in Guichun 8 in comparison to Huachun 6 in Yizhou and Du＇an sites.After inoculation of Rhizobium,both the quantity of Rhizobium and fresh weight of above ground parts increased in different soybean varieties planted in different planting areas.[Conclusion]The results revealed feasibility of Rhizobium inoculation technique for yield increase in soybean,however,selection of suitable Rhizobium species and its compatibility with soybean varieties need to be taken into account,depending on the local entironmental conditions.
