摘要:: 为筛选出红松嫁接苗期合理施肥方案，以红松嫁接苗（J_5-1）为试验材料，以不施肥处理为对照，按L₉（3⁴）设计9个不同施肥处理，每个处理重复3次，分析了不同施肥处理对红松嫁接苗苗高、接穗高和接穗基径生长量的影响。结果表明：不同施肥处理均能显著提高嫁接苗的生长指标（P＜0.05），尤其是在N₃P₁K₃（尿素1.5 g/株+过磷酸钙0.5 g/株+硫酸钾1.5 g/株）配比下促进红松嫁接苗生长效果极显著（P＜0.01），苗高生长量最高可达7 cm，接穗生长量最高可达5.5 cm，比对照组高71.88%，接穗基径生长量最高可达4.59 mm，比对照组高106%。研究结果为红松嫁接苗的初期施肥抚育管理提供了依据。

Abstract:: To confirm the reasonable fertilization plan for the grafting seedling stage of Pinus koraiensis, the grafted seedlings (J_5-1) were used as the experimental material. With no fertilization treatment as the control, 9 different fertilization treatments were designed according to L₉ (3⁴), with each treatment for three times. The effects of different fertilization treatments on the seedling height, scion height, and scion base diameter growth were investigated and analyzed. The results showed that different fertilization treatments could significantly improve the growth of grafted seedlings (P<0.05). Especially the combination (1.5 g urea+0.5 g superphosphate+1.5 g potassium sulfate for each seedling) promoted the growth significantly (P<0.01), with the seedling height growth of 7 cm, and the scion growth of 5.5 cm, 71.88% higher than that of the control, with the scion base diameter growth of 4.59 mm, 106% higher than that of the control. The research results could provide a theoretical basis for the initial fertilization and nurturing management of grafted P. koraiensis seedlings.
