Pinus tabulaeformis Carr .Seedlings were soaked 2 h with 25 mg · kg -1 green biological regulator No . GGR .The results showed this measure promoted seed germination and improved seedling emergence with 7 .11%-13.33% ,developed root system ,increased lateral roots number ,dry matter accumulation ,as well as improved bio-mass yield with 15 .98% -20 .96% .Input-output ratio was 1 :13 .3-1:17 .5 ,which achieved higher economic effi-ciency .It is easy for people to master and practice this soaking technique .
