摘　　要：采用随机区组设计对红锥实生容器苗进行不同浓度、频率的施肥试验,探讨不同营养水平对其生长指标的影响,旨在揭示红锥实生容器苗生长对复合肥的需求,确定其适宜施肥量和频率。综合分析苗木生长量、生物量等形态特征及质量指数,考虑培育成本,得出培育红锥容器苗施用复合肥的合适处理是浓度1.0%、频率21 d。Aiming at exploring the effects of nutrition level on the seedling growth indexes, revealing the actual need of fertilizer by the seedlings, and then determining the rational application dosage and frequency, a fertilization experiment was conducted with Castanopsis hystrix container bred seedlings, which were treated with different levels of fertilizer concentrations at various application frequencies based on a randomized block design. A compre- hensive analysis on the growth rate, biomass, some morphological characters and qualitative indices of the tested seedlings was made. Taking the cost into consideration, it was showed that the suitable fertilization regime for the Castanopsis hystrix container seedlings was to apply 1.0% compound fertilizer once every 21 days.
