摘　　要：４年试验结果表明，在高海拔和冷凉的西宁生态条件下，大豆东农７９－６４－５品系的生育期平均１１８±５天。播种期提早，出苗期相应延长，出苗－始花期也相应延长。出苗６０天前后茎和叶生长速度最快。出苗７０天前后开始结荚。出苗８０天后植株鲜重和干重增长速度最快。出苗９０天，株高、主茎粗和单株叶面积、荚果数、鲜重和干重均达一生最大值。此后生长急剧减缓渐趋成熟。亩产最高可达１５２ｋｇ。The results of test of 4 years indicated that the mean gorwth period duration of Dongnong 79-64-5 soybean strain was 118±5 days under ecological condition of high altitude and cold Xining. The Sowing date shift to an earlier time would result the prolongation of its emergence date and the emergence to the blossom date. The rapidest growth speed of the stems and leaves were around 60 days emergence. The rapidest speed of increase of fresh and dry weight of plants was 80 days after emergence. Pods setting started around 70 days after emergence. The maximum plant height, main stem diameter, leaves area, pod number, fresh and dry weight per plant achieved 90 days after emergence. Herefter rapidly come into slow growth and gradual maturation. The highest yield per mu was 152kg.
