研究表明：巴青1号青稞在青海高寒地区种植，大部分在抽穗之后开花，小花开放顺序通常由中部向上下两端开放，单个花序开花持续时间为5～8d，群体开花时间可达到10d。一日开花高峰在上午09～11时和下午13-15时，青稞开花的适宜温度为17．2℃～22．6℃，相对湿度55％～65％，结实率为85．7％。
The flowering behavior of highland barley was studied.The results showed that Baqing NO.1 of highland barley was in most flowering after heading stage.The opening order of the flowers was usually from middle-upper to the two ends.The flowering duration time of per spiked was 5 to 8 days,and groups spikes was 10 days.The flowering peak of highland barley was mainly at 09 :00~11:00 pm and 13:00~15:00 am everyday.The most favorable temperature of bud opening was between 17.2℃ and 22.6℃ and the most suitable humidity was 55%～65%.And its seed setting rate was 85.7%.
