摘　　要：为考察不同施肥方式对樟子松幼苗生长的影响,以甘肃武威凉州地区为试验地,对樟子松幼苗设置不同的施肥量,考察不同施肥处理下樟子松幼苗的生长情况与生理特性。结果显示,不同施肥量处理后下的樟子松幼苗株高、地径以及单株总生物量差异显著,其中施肥量为40 g/株时樟子松幼苗株高、地径、单株总生物量以及叶绿素b含量达到最大值,显著高于其他T处理方法。在此施肥条件下,樟子松幼苗株高较空白对照增加了34.33%,地径较空白对照提高了51.67%,单株总生物量较空白对照提高了69.94%,叶绿素b含量较空白对照提高了32.56%。In order to investigate the effects of different fertilization methods on the growth of Pinus sylvestris seedlings,the growth and physiological characteristics of Pinus sylvestris seedlings under different fertilization treatments were investigated in Liangzhou area.The results showed that there were significant differences in seedling height,ground diameter and total biomass per plant under different fertilizer treatments.The seedling height,ground diameter,total biomass per plant and chlorophyll b content reached the maximum value when the fertilizer rate was 40 g/plant,which was significantly higher than that under other T treatments.Under these fertilization conditions,the seedling height,ground diameter,total biomass and chlorophyll b content were increased by 34.33%,51.67%,69.94%and 32.56%respectively compared with the control.
