Abstract
In the initial growth stage of Acacia confusa and Acacia mearnsil fallow afforestation, the height growth increase of the C treatment (Control group) is greater than A treatment (increasing depth and width cave sites) and B treatment (furrow sites) and has significant difference, and There was no significant difference in the development of root system and the ability to enhance the resistance to wind damage among three treatment sites. Because the tree is still in the early growth stage, and we can not be concluded that there is no effect in the soil physical property Improvement treatment between increasing depth sites and furrow sites, and it was still to be observed later.
