Effects of pre-sowing soybean seed inoculation with Bradyrhizobium japonicum alone or with mixed inoculants containing soybean rhizobia and Azotobacter chroococcum were compared. In the pot experiment all the tested strains of soybean rhizobia in pure cultures or in mixtures with A. chroococcum significantly improved nodulation of soybean plants and seed yields of this crop. In micro-plot experiments pre-sowing soybean seeds treatment with the inoculant containing the most effective strain 94P of B. japonicum alone or with the mixed inoculant of strain 94P and A. chroococcum were equally effective in improving nodulation intensity and seed yields of soybean in comparison to the uninoculated soybean.
比较了单独接种大豆根瘤菌（Bradyrhizobium japonicum）或接种含有大豆根瘤菌和固氮菌（Azotobacter chroococcum）的混合菌剂对大豆种子的影响。在盆栽试验中，所有测试的大豆根瘤菌纯培养物或与固氮菌混合的培养物都显著提高了大豆植株的结瘤和该作物的种子产量。在小区试验中，与未接种大豆的大豆相比，单独用最有效的菌株 94P 或用菌株 94P 和固氮菌混合的接种剂处理大豆种子，同样可以有效提高大豆的结瘤强度和种子产量。
