Abstract: The stock age,grafting method,using protection cover,grafting time and so on would influence the svrvival rate about the grafting of Pinus armandii.The results of the experiment showed that the better grafting methods were graf ting of hard branches and grafting of tender branches.The stock age was from three to five years,and good results came from grafting in the middle of the stock with the tender branches protected by covers and better operating techniques.Compared with other weather conditions,grafting was better in cloudy and rainy days,and the living rate was higher than that in sunny days.The grafting time about hard branches of grafting was from February to March,and about tender branches of grafting was from March to May.The svrvival rate about grafting of Pinus armandii has been increased,and grafting time has been also prolonged through this experiment.
