摘　　要：[Objective] This study aimed to investigate the effect of inoculation with various rhizobium strains on growth status, phosphorus uptake, yield and quality of soybean plants. [Method] Using Dongnong 42 and Dongnong 46 as experimental soybeans, four treatments were designed, including non-inoculated CK group and three treatment groups inoculated respectively with rhizobium strains R2, R, and Rs, to analysis the effects of rhizobium inoculation on growth status, phosphorus uptake, yield and quality of soybean plants. [Result] Inoculation with different rhizobium strains could significantly increase the biomass and phosphorus content of the roots and shoots of Dongnong 42, to be specific, rhizobium strain R2 showed the best ef- fect, followed by Rs, and those of roots were improved greater than the shoots; in- oculation with rhizobium could significantly increase the yield of Dongnong 42, and R5 showed the best effect, but the yield of Dongnong 46 was decreased; after in- oculated with rhizobium, the protein content and fat content of soybean were signifi- cantly increased, and R2 showed the best effect, but the effects on different varieties varied, to be specific, the protein content of Dongnong 42 was significantly in- creased, while the fat content of Dongnong 46 was significantly increased; different rhizobium strains inoculated to different soybean varieties showed different effects. Inoculation with suitable rhizobium can improve plant growth characteristics, promote phosphorus uptake of plants, increase soybean yield, and effectively improve soy- bean quality. [Conclusion] This study provides theoretical basis for solving the prob- lem of soil phosphorus deficiency, increasing soybean yield and improving soybean quality in the future.[目的]探讨接种不同根瘤菌对大豆植株生长状况、磷素吸收及产量品质的影响。[方法]以东农42和东农46为供试大豆,试验设4个处理,即不接种根瘤菌的CK组和分别接种根瘤菌R2、R4和R5的处理组,分析接种根瘤菌对大豆植株生长状况、磷素吸收以及产量和品质的影响。[结果]接种不同的根瘤菌可以显著增加东农42大豆植株根部、地上部的干生物量和磷含量,其中,根瘤菌R2的效果最好,其次是R5,并且根部增幅均较冠部明显;接种根瘤菌可以使东农42的产量明显增加,R5表现最好,但东农46的产量降低;接种根瘤菌后,大豆的蛋白质和脂肪的含量显著增加,R2表现最好,但是不同品种表现效果不同,东农42蛋白质含量增加明显,而东农46脂肪含量增加明显。不同菌种接种在不同品种大豆上表现效果是不同的。大豆接种适合的根瘤菌可以改善植株的生长特性,促进植株对磷素的吸收,提高大豆的产量,有效改善大豆品质。[结论]该研究结果为今后解决土壤缺磷问题、增加大豆产量和提高大豆品质提供了理论基础。
