Based on the daily temperature,the daily precipitation,≥ 10 ℃ effective accumulated temperature,10 cm ground temperature,density,yield and number of day growth of different soybean growth periods,from 1981 to 2014 of seven representative agrometeorological observatories in Heilongjiang Province,the suitable temperature and precipitation of Heilongjiang Province soybean were analyzed statistically,and combined with previous research results to obtain quantitative indexes.The results showed that from the sowing stage to the emergence stage,the suitable ground temperature of 10cm was 8 ℃.From the emergence stage to the flowering stage,the suitable average temperature was 18-22 ℃,and the suitable average precipitation was 70-145 mm.From the flowering stage to the pod stage,the suitable average temperature was 19-25 ℃ and the suitable average precipitation was 70-120 mm.From the pod stage to the maturity stage,the suitable average temperature was 15-21 ℃ and the suitable average precipitation was 110-185 mm.
