对黑龙江省九三地区1954～1996年大豆单产与备年气象因子（包括大豆生育期间5～9月份降水量、各月平均气温、光照、无霜期、≥10℃积温等）进行了相关分析．结果表明，大豆产量与≥10℃积温、无霜期呈高度正相关，其相关系数分别为0．517和0．509；另外夏早与夏涝也影响大豆产量． The correlation analysis was made between the yield and annual meteorological factors of soybean in 1994 ~ 1996 in Jiu San region of Heilongjiang province (including precipitation from May to September in soybean growing season, monthly average temperature, light, frost - free period, accumulated temperature ≥10 ℃). The results showed that there was a highly positive correlation between soybean yield and ≥10 ℃ accumulated temperature and frost-free period, and the correlation coefficients were 0.517 and 0.509 respectively. In addition, the early summer and summer floods also affected the soybean yield.
