采用切根及喷云大-120 处理对刺槐苗木生长的效果进行试验, 结果表明: 切根和喷云大- 120 能够促进刺槐苗木的生长; 切根、云大-120 处理及其交互作用, 对刺槐苗期生长有一定的影响; 在各处理中, 切根喷云大- 120 和不切根喷云大- 120 的效果较好, 其次是切根不喷云大- 120。不切根喷云大- 120 的苗高、地径、冠幅、茎叶鲜重、侧枝数、根长、根幅、根鲜重、主根发育明显的株数和根瘤等性状平均值分别比对照高77-80% 、13-89% 、29-97 % 、140-72 % 、353-33% 、24-63% 、6-23% 、105-54 % 、21-90 % 、34-78% 。
The results showed that cut rooting and spraying Yun - Da - 120 can promote the growth of seedlings of Robinia pseudoacacia. The effects of root cutting, cloud - 120 treatment and their interactions, The effect on the growth of Robinia Pseudoacacia seedlings had a certain effect. In each treatment, the effects of cutting root sprayed Yun-120 and uncut root spraying Yun-120 were better, followed by that of cutting root without spraying cloud-120. The results showed that seedling height, diameter, crown width, fresh weight of stems and leaves, number of lateral branches, root length, root width, fresh weight, number of obvious root nodules and nodules were significantly higher than those of control High 77-80%, 13-89%, 29-97%, 140-72%, 353-33%, 24-63%, 6-23%, 105-54%, 21-90%, 34-78% .
