本文件展示了使用较低数量浓度的超细气泡（UFB）促进大麦种子发芽的指南。这是通过以符合ISO 23016-2的大麦种子发芽率相关数据为起点，然后评估通过改变发芽时间促进大麦种子发芽所需的超细气泡水的最小数浓度范围来实现的。

This document demonstrates guidelines for promoting the germination of barley seeds with a lower number concentration of ultrafine bubbles (UFB). This is achieved by taking the data concerning the germination ratio of barley seeds conforming to ISO 23016-2 as a starting point and then evaluating the minimum number concentration range of ultrafine bubble water necessary for promoting the effect on germination of barely seeds by changing germination time.
