摘　　要：８ａ引种试验结果表明，大豆７９６４５选系在西宁生态条件下生育期平均１１６ｄ。出苗６０ｄ左右茎叶生长速度最快，７０ｄ前后开始结荚，８０ｄ左右植株鲜重和干重增长速度最快，９０ｄ左右营养生长量、单株荚果数和物质生产积累量均达一生最高值，１００ｄ左右荚果大小基本定型。此后生长急剧减缓渐趋成熟。最高产量达２８９５．１ｋｇ／ｈｍ２。The soybean introduction experiments for 8 years indicated that the mean growth period duration were around 116 days of Dongnong 79645 soybean strain in ecological condition of Xining, the rapidest growth speed of the stems and leaves were around emergence 60 days. Start setting pods were around emergence 70 days. The rapidest increase speed of fresh and dry weight of plant were around emergence 80 days. The vegetative growth amount,the plant pods count,the matter production and accumulation amount achieved the biggest value were around emergence 90 days. The pod size development finished were around emergence 100 days. The highest yield achieved 2895.1kg/hm 2.
