切根及喷云大- 120 处理对郭芬柏苗木效果的试验结果表明: 切根和喷云大- 120 处理能够促进郭芬柏苗木的生长; 切根、喷云大-120 处理及其交互作用, 对郭芬柏苗期生长有显著影响, 特别是切根喷云大-120 处理与对照间的差异十分明显; 在各处理中, 切根喷云大- 120 的效果最好, 其苗高、地径、冠幅、单株茎叶鲜重、侧枝数、根长、根幅、单株根鲜重、主根发育明显的株数和侧根数等性状分别比对照高32-44 % 、34-62 % 、20-56% 、114-79% 、17-96 % 、12-73 % 、9-45% 、39-76% 、-60-14 % 和-10-75 % , 其次是切根不喷云大-120 和不切根喷云大-120。
The results showed that the effects of cutting root and spraying cloud big - 120 treatment on the growth of seedlings of Gufenbai seedlings; the effects of root cutting, spraying cloud treatment and its interaction on the seedling growth of Guo Fenbai, The seedling growth had a significant effect, especially the difference between the root-cutting spray cloud-120 treatment and the control was obvious. In each treatment, the effect of cutting root spray cloud-120 was the best, and its height, diameter and crown The fresh weight per plant, branch number, root length, root width, fresh weight per plant, obvious number of stalks and lateral root number were 32-44%, 34-62%, 20-34% 56%, 114-79%, 17-96%, 12-73%, 9-45%, 39-76%, -60-14% and -10-75% And do not cut root spray big -120.
