We present results of a search for 22 GHz NH3(1,1) and (2,2) inversion lines toward 220 sources(1.1mm flux >5Jy) seen in the Bolocam Galactic Plane Survey (BGPS) using the Nanshan 25m radio telescope. The BGPS is a blind survey of the Northern Galactic plane in 1.1 mm thermal dust emission that has cataloged star-forming regions. We detected 173 ammonia sources, among which 127 sources new detected. The detection rate is 78%. We present detection statistics, physical properties of the ammonia sources, and correlations with BGPS sources.
