Growth Evaluation Of The 2 Kinds Of Pinus Sylvestris Var.Mongolica Seedlings In Different Transplantation Environment

Pinus sylvestris var.mongolica is one of the main tree species in Midwest of the Inner Mongolia Autonomous Region plantation,in terms of species conservation,scientific research,ecological and economic benefits,have research value and protection-In this study,la of Pinus sylvestris var.mongolica mycorrhizal and light matrix nutrition bag seedlings as the research object,made study on the growth of different planting environment of these two kinds of Pinus sylvestris var.mongolica seedlings,and reached the following conclusions:1.Intelligent greenhouse can provide an ideal growing environment for improving largely survival rate,growth and seedling biomass of the two kinds of Pinus sylvestris var.mongolica.2.Pinus sylvestris var.mongolica mycorrhizal.seedlings are superior to the light matrix nutrition bag seedlings in the intelligent greenhouses and open space,where transplanting survival rate,growth and large biomass of seedlings are higher.Under solar panels light,the transplanting survival rate shows that the Pinus sylvestris var.mongolica mycorrhizal seedlings are superior to the light matrix nutrition bag seedlings,but the growth capacity and seedling biomass are light matrix nutrition bag seedlings are superior to the light matrix nutrition bag seedlings.3.In the same growth environment,the environmental adaptability of Pinus sylvestris var.mongolica seedlings is better environmental adaptability than the light matrix nutrition bag seedlings.
