Abstract:

To explore the effects of different modes of rhizobium inoculation on the biomass accumulation and the yield, three isolated, identified and purified rhizobium strains, and multiple soybean varieties of SUINONG35 was selected as materials, the effects of the three rhizobium inoculation application methods of seed dressing, seed fertilizer, and drip application on the rhizobia nodule number, dry weight of root nodules, aboveground dry matter accumulation and distribution, yield and its composition were compared. The results showed that the rhizobium inoculation could promote the nodule formation of soybean roots, among which, seed dressing inoculation method of SN7-2, seed fertilization inoculation method for SMH12 and SN7-2, and drip inoculation for T6 had the best nodule effect. Seed dressing inoculation method of SN7-2, seed fertilization inoculation method for SMH12 and SN7-2, and drip inoculation for T6 coiled significantly promote the dry matter accumulation of soybean. Seed dressing method and seed fertilizer inoculation method of SN7-2, and drip inoculation method for T6 could promote dry matter distribution to reproductive organs. The seed yield of soybean improved by increasing the number of main stem nodes, pod number per plant, grain number per plant and 100 grain weight with different inoculation methods. The seed dressing method and seed fertilizer method were suitable for the SN7-2, whilst, for the T6, the suitable application method was dripping.
