绿枝扦插技术是加速啤酒花品种更新繁殖的最快途径。绿枝扦插技术就是把生长健壮的枝蔓截剪 ,经过消毒和生长调节剂处理后 ,直接插入苗床土 ,通过对湿度、光照、温度的调控达到生根育苗的效果。但是扦插条生根需要 2 0～ 2 5天 ,在 6～ 8月温度很高的季节 ,扦插成活率很难提高 Green branch cutting technology is to accelerate the hopping breed update the fastest way to reproduce. Green branch cutting technology is to grow robust branch vine cut, after disinfection and growth regulator treatment, directly into the soil bed, through the regulation of humidity, light and temperature to achieve root nursery effect. However, it takes 20 ~ 25 days for rooting of cuttings, and the survival rate of cuttings is difficult to increase in the season with high temperature from June to August
