• Abstract: Different doses of active root promoters were used to treat Rhododendron in spring. 15 days after treatment, it was found that active root promoters promoted the formation and growth of new roots in different degrees, among which active root promoters 4 The effect of mg / L treatment area was the most obvious, which increased the number of root basins of the Yellow seedlings by 2.656 times compared with the control, and increased the length and growth range of the new roots of the normal seedlings by 49.7% and 8% respectively, which had a high value in production. 不同剂量的活性促根剂于春季处理四季杜鹃，处理后 15 d 调查发现， 活性促根剂不同程度的促进了新根的生成及生长，其中以活性促根剂 4 mg/L 处 理区效果最为明显，使黄化苗的发根盆数较对照增加了 2.656 倍，使正常苗的新 根长度、增长幅度分别较对照提高了 49.7％及 8％，在生产上具较高的利用价值。
