摘　　要：[目的]探讨施肥对膝柄木苗木生长的影响。[方法]以膝柄木容器苗为试验材料,研究不同肥料组合对1年生苗高度和地径的影响。[结果]与对照相比,0.5%活性肥、0.5%复合肥、0.5%复合肥+0.5%活性肥处理对膝柄木苗高和地径有一定的促进作用,其中0.5%复合肥+0.5%活性肥处理对苗高和地径的生长均有极显著促进作用,0.5%复合肥处理对地径生长有极显著的促进作用、对苗高生长的促进作用不显著,0.5%活性肥处理对苗高和地径生长的促进作用均不显著。[结论]0.5%复合肥+0.5%活性肥处理能有效促进膝柄木苗高和地径的生长。[Objective]To explore the effect of fertilization on Bhesa sinensis seedling growth. [Method]One-year-old container seedlings of B. sinensis were used as research material,effects of different fertilizers and their combination on B. sinensis seedling height and ground diameter were studied. [Result]Results showed that all fertilization treatments promoted the growth of B. sinensis seedling height and ground diameter. The combination of 0. 5% compound fertilizer and 0. 5% active fertilizer has significant promoting effect both on the B. sinensis seedling height and diameter growth. 0. 5% compound fertilizer has significant positive effect on ground diameter,but it has no significant effect on seedling height. 0. 5% active fertilizer has no significant effect on seedling height and diameter growth. [Conclusion]The combination of 0. 5%compound fertilizer and 0. 5% active fertilizer has significant promoting on B. sinensis seedling height and ground diameter.
