在胶东半岛生态条件下,对春性啤酒大麦进行了观察研究。春播情况下从播种到成熟100—112天,需0℃以上积温1300℃左右。出苗后8天生长锥开始伸长,15天进入二棱期,具有明显的“前短后长”的生育特点。将幼穗分化进程分为7个时期,确定了各分化期的形态指标,并阐明了幼穗分化进程与叶片、节间及大田生育期的同步关系。
In the Jiaodong Peninsula ecological conditions, the spring of barley was observed. Spring sowing conditions from sowing to maturity 100-112 days, above 0 ℃ need to accumulate about 1300 ℃ temperature. The growth cone began to elongate 8 days after emergence and entered the two-ridge period in 15 days, with the obvious characteristics of “short before long and after long”. The process of spike differentiation was divided into seven stages, the morphological indexes of each stage were determined, and the synchronization of spike differentiation stage and leaf growth stage was clarified.
