Abstract: In this paper, different fertilization methods such as rare earth, nitrogen, phosphorus and potassium fertilizer were used to cultivate young camellia oleifera forest. Nine fertilization methods were compared with two groups of control group, and the growth of crown width and plant height of young camellia oleifera forest under different fertilization methods were compared. The results showed that the growth and yield of camellia oleifera were greatly different when the same potassium fertilizer concentration was used in treatment 3 and treatment 7, The results show that K fertilizer plays a certain role in the growth of camellia oleifera young forest, which is not the main factor. The effect of applying rare earth micro fertilizer alone is limited, so it should be combined with phosphorus fertilizer, nitrogen fertilizer and potassium fertilizer, pay attention to the application amount and construction time interval, and control it within the best limit. At the same time, in the process of rare earth fertilization, appropriate fertilization amount should be adopted in combination with plant types and their growth stages.
