【摘要】 以锐齿栎当年播种容器苗为研究对象，选择5种容器规格，采用相同基质进行播种育苗，探讨不同容器规格对锐齿栎苗木生长、生物量和根系发育的影响。结果表明：容器规格显著影响锐齿栎播种苗的生长、根系发育和生物量积累，锐齿栎幼苗的生长、生物量、主根长和侧根数量均随着容器规格的增大而增大，其中21 cm×26 cm和30 cm×30 cm容器的苗高、地径、根系直立率、≤2 cm侧根数、根和叶生物量均显著高于其他规格，分别比12 cm×18 cm、16 cm×20 cm、18 cm×23 cm规格高20.5%～61.7%、16.2%～57.4%、21.4%～113.9%、3.3%～116.5%、2.7%～82.6%和8.0%～113.3%。因此，规格为21 cm×26 cm容器为培育锐齿栎当年播种苗的最佳选择，在提高苗木质量的同时，还能有效控制主根长度，促进根系发育。更多还原

【Abstract】 Taking the container seedlings of Quercus aliena var.Acuteserrata sown in the current year as the research object,five container specifications were selected and the same substrate was used for sowing and seedling raising to explore the effects of different container specifications on the growth,biomass and root development of Quercus aliena var.Acuteserrata seedlings.The results showed that the size of the container significantly affected seedling growth,root development,and biomass accumulation.The growth,biomass,taproot length,and the number of lateral roots of Q.aliena var.Acuteserrata seedlings all increased with container size.Among them,the seedling height,ground diameter,root upright rate,number of lateral roots ≤2 cm,and root and leaf biomass of the 21 cm×26 cm and 30 cm×30 cm containers were significantly higher than those of other specifications.They were 20.5%～61.7%,16.2%～57.4%,21.4%～113.9%,3.3%～116.5%,2.7%～82.6% and 8.0%～113.3% higher than the specifications of 12 cm×18 cm,16 cm×20 cm and 18 cm×23 cm respectively.Therefore,the containers with the specification of 21 cm ×26 cm were the most suitable for cultivating Q.aliena var.Acuteserrata seedlings sown in the same year,as they not only improved the quality of the seedlings but also effectively controlled taproot length and promoted root system development.更多还原
