Abstract
Soaking root with No. 3 , 6 and 7 ABT rooting powder in different periods in Pinus tabulaerormis afforestation, results show that 60 and 90 min. are both suitable periods. Survival rate, top growth increment of seedlings and regenerated root number are increased by 11. 5% ,29% and 14. 5% respectively. No. 3, 6 and 7 ABT rooting powder all can increase survival rates, promote seedling growth and increase above ground biomass, among the three, No. 3 ABT rooting powder is best of all.
