Growth Relationship Between Transplanting and Non-transplanting of Seedlings of Pinus Sylvestris Var.Mongolica

Investigation of survival ratio and growth after transplanting and non-transplanting indicated that transplanting of Pinus sylvestris var.mongolica should adopt 1-year seedlings .Adopting lower quality seedlings could reduce prominently the survival rate of transplanting .Seedlings of Pinus Sylvestris var.mongolica should be drawn enough frozen water to fill before outplanting and it could ensure survival rate of transplanting seedlings.There existed a positive correlation between moisture content and survival rate of transplanting seedlings in transplantings practices. People should lift with transplanting along with planting. (seedlings should be dip in mud ).It could reduce baring time of seedlings outside.
