Abstract
Effect of rootstock selection,grafting time,grafting methods on survival rate growth of Pinus koraiensis were analyzed.Result shows that: Pinus sylvestris var.mongolica,Pinus tabulaeformis,Pinus densiflora all can be used as rootstock;single-bud appear optimal than multiple-bud;appropriate early grafting received favorable on scion lignification improvement;result of orthogonal experiment shows that :the optimal treatment combination is A1B1C1,namely the the combination of stock being Pinus sylvestris var.mongolica+bud-side wedge grafting being in mid-April can obtain survival rate being over 90%.
