Title: Preliminary Analysis on the Experiment of Acacia delbata Cultivation
Abstract: The experiment of root cutting and spraying BR-120 to Acacia delbata shows cutting roots can promote growth of the parts under ground,while spraying BR-120 can improve the growth of the parts above ground.The effect on the growth of seedlings by cutting roots and spraying BR-120 lays mainly in 5 characters, namely height, canopy, root range, and fresh weight of roots and development of main roots.In various treatments, spraying BR-120 without cutting shows the best effect,in witch the height,ground diameter,canopy,fresh weight of leaf and stem,number of lateral branches,length and range of the roots are 17 35%,5 26%,35 92%,36 02%,775 00%,8 00%and 3 35% higher than those of the control.However,the average value of the number of lateral roots and fresh weight of roots are 0 33% and 5 71% lower than those of the control.
