Third, water, soil, plant trees to be maintained, it is necessary to use tree planting to curb soil erosion, afforestation must be, because the trees are as large as the crown of the root system, like giant hands firmly grasp the general soil.

第三，植树使水土得到保持，就要利用植树来抑制水土流失，所以必须要植树造林，因为树木有像树冠那样庞大的根系，能像巨手一般牢牢抓住土壤。

Comparing as BA, 0.1mg·L〓 TDZ was more effective in inducing germinating and developing of buds, regenerating prolific caespitose buds via organogenesis, promoting rhizogenesis and activity of root system greatly, as a result, acclimation survival rate was improved significantly.
