The invention relates to low-temperature
phosphate solubilization Sinorhizobium fredii and inoculant thereof. The strain name is ATHC-2, the classification name is Sinorhizobium sp., the preservation unit is the China General
Microbiological Culture Collection Center, the preservation number is CGMCC No. 10651, the preservation date is March 20, 2015, and the preservation address is No. 3, NO. 1 Courtyard, Beichen West Road, Chaoyang District, Beijing. The
bacterial strain ATHC-2 disclosed by the invention can
resist the influence on the growth of the
bacterial strain ATHC-2 by low temperature, and has
high phosphate solubilization activity. Low-temperature-resistant
rhizobium inoculant is used for alleviating influence on soybean nodulation and
nitrogen fixation in agricultural production, improve
soil fertility, reduce the use amount of
fertilizer and improve the yield and the quality of crops including soybean and the like.
