Abstract:
Ten superior rhizobia strains matched well with the soybean (Glycine max) cultivar Jindou 25 were screened from 20 rhizobia varieties that isolated from Loess Plateau region according to nodule numbers, nodule dry weights, plant dry weights and total N contents by vermiculite and soil pot experiments. Subsequently, three inoculation methods were adopted in field experiments and two strains of Bradyrhizobium liaoningense 4345 and Sinorhizobium fredii 4338 were selected by their performance of nitrogen fixing and competitive nodulation ability from the 10 strains in drought resistant and soil pot experiments. Spraying showed better effects in plant dry weight, nodulation competitiveness, seed yield and total N content than the other two treatments for B. liaoningense 4345. Moreover, seed dressing showed the best effects in plant dry weight, nodulation competitiveness, seed yield and total N content for S. fredii 4338 in the field experiment. The results indicated that the inoculation methods of spraying and seed dressing were Suitable for rhizobium application in Loess Plateau region.
