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。
Abstract
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 diame-ter were studied.[Result]Results showed that all fertilization treatments promoted the growth of B.sinensis seedling height and ground diame-ter.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.
