This study investigates the effects of different fertilization treatments on the growth of 5-year-old Pinus sylves-tris var.mongolica container seedlings in a 30 cm × 30 cm cup,as well as the distribution of total organic C,total N,total P,and total K nutrients in plant leaves and branches.The aim is to explore the optimal fertilization scheme for the growth benefits of Pinus sylvestris var.mongolica container seedlings in the Zhanggutai area,with the aim of improving the pro-ductivity and healthy management of Pinus sylvestris var.mongolica plantations.The results showed that the T-3 treatment(ammonium sulfate 2.50 g/plant,calcium superphosphate 4.00 g/plant,potassium sulfate 1.25 g/plant)showed the best performance in seedling height and diameter growth,reaching 27.75 cm and 0.35 cm respectively.Among the 5 fertil-ization treatments,the T-3 treatment had the best comprehensive effect on the growth and nutrient distribution of 30 cm x 30 cm cup container seedlings of Pinus sylvestris var.mongolica.
