我县主要农作物种子的检验工作中,以大麦种子的发芽率测定较复杂。主要原因是:大麦种子的休眠期较小麦、水稻、棉花等种子要长得多,在当年种子、收获后相当一段时间内,难于直接进行种子的实际发芽率测定,即使用有关的物理、化学处理,也难于有效地打破种子的休眠状态,获得种子的实际发芽率;其次,在夏季高温条件下, In our county main crop seed testing, the determination of germination rate of barley seeds more complicated. The main reason for this is that barley seeds have a much longer dormancy period than wheat, rice, cotton and other seeds. In the current year, it is difficult to determine the actual germination rate of the seeds in a relatively long period of time after harvesting, that is, using the relevant physical and chemical Treatment, it is difficult to effectively break the dormancy state of seeds, to obtain the actual seed germination rate; secondly, under the conditions of high temperature in summer,
