摘　　要：为探究不同施肥方式对樟子松幼苗生长的影响,通过施肥总量的不同配比,分别观察了不同配比复合肥和尿素及不同施肥量对樟子松幼苗生长的影响。结果表明:施肥方式对樟子松幼苗的生长指标产生了显著影响,其中处理组C表现出最佳的生长效果,其平均苗高、地径、主根长和侧根数分别为30.96 cm、6.98 cm、59.43 cm、28.61个,分别比对照组提高了47.42%、33.56%、17.59%和34.11%,其次是处理组B、D、G、F、E。在生物量方面,处理组C也表现出最高的生长效果,与生长指标研究结果一致,该施肥方式下其地上部位生物量为39.56 g/株,地下部位生物量为32.89 g/株,整株生物量为72.45 g/株,分别比对照组提高了30.16%、62.37%、42.91%。指出了适当增加有机肥比例可以显著促进樟子松幼苗的生长发育。研究为樟子松幼苗种植过程中施肥方式的选择提供了重要参考依据。This study aims to investigate the effects of different fertilization methods on the growth of Pinus sylvestris var.mongolica seedlings.The effects of different ratios of compound fertilizer,urea and fertilizer application on the growth of Pinus sylvestris var.mongolica seedlings were observed.The fertilization method had a significant impact on the growth indicators of Pinus sylvestris var.mongolica seedlings,among which treatment group C showed the best growth effect,with an average seedling height,ground diameter,main root length,and lateral root number of 30.96 cm,6.98 cm,59.43 cm,and 28.61,respectively,which were increased by 47.42%,33.56%,17.59%,and 34.11%compared with the control group,followed by treatment groups B,D,G,F,and E.In terms of biomass,treatment group C also showed the highest growth effect,consistent with the research results of growth indicators.Under this fertilization method,the aboveground biomass was 39.56 g/plant.The underground biomass was 32.89 g/plant,and the whole biomass was 39.56 g/plant.The biomass of the plant was 72.45 g/plant,which increased by 30.16%,62.37%,and 42.91%respectively compared with the control group.Properly increasing the proportion of organic fertilizer can significantly promote the growth and development of Pinus sylvestris var.mongolica seedlings,which provides important reference for the selection of fertilization methods during the planting process of Pinus sylvestris var.mongolica seedlings.
