摘　　要：试验以"791宽叶雪韭"为试材,采用水培的方法,将单体型和组合型2种类型漂浮板在不同催芽时间(7、8、9d)内对韭菜生长、生理指标等进行了分析比较,以期获得最适韭菜水培的漂浮板类型。结果表明:2种漂浮板随着浸液时间的延迟,发芽率逐渐增加;在韭菜假茎粗、叶片数、叶长、叶宽、根体积、根系活力、叶绿素总量、干鲜质量上,处理间不存在显著性差异;在青苔发生上,组合型漂浮板比单体漂浮板减少81.37%,显著降低了青苔面积。说明组合型漂浮板可以作为韭菜水培的一种新选择,并能起到有效减少青苔面积的作用。In order to obtain the optimal hydroponic Chinese Chive floating plate type,taking‘791wide blade Chinese chive＇as the test material.The effects of two types of floating plates（solo and combined floating plate）on the growth and physiological indexes of hydroponic Allium tuberosum under different germination time were studied.The results showed that the germination rate of both the floating plates was gradually increased with the delayed time of immersion.In stem diameter,leaf number,leaf width,root volume,root activity,total chlorophyll content,fresh and dry weight,there were no significant difference between the two types of floating plates;the combined floating plate significantly reduced the area of moss to 81.37%.Combined floating plate could be used as a new choice of hydroponic Chinese chive and played an effective role in reducing the area of moss.
