摘　　要：Calophyllum polyanthum is a climax tree species in the tropical rain forest of south Yunnan, China. It has excellent timber qualities and straight and orbicular bole which be favored by the local residents and be prepared for selection in afforestation. But so far, the research on the afforestation techniques of this species is scarce. In this paper, we demonstrated the silviculture characters of C. polyanthum through the researches of its seed and seedling biology, the techniques of nursery, and the ecological and geographic adaptability experients in different climate zones. The results showed that:①The seeds of C. polyanthum are not resistant to storage, less than 40% of the seeds can germinate after 3 months storage under the condition of room temperature, so, it should be collected and sowed as soon as the fruits are ripe.②It is harder to be survived by planting naked root seedlings due to its flourishing and less fibrous root taproot.③The seedlings can not bear the direct sunlight, but the full sunlight is needed after several years growing. Therefore, one year old seedlings must be planted in shade or the understory of the forest, 2 years old seedlings can be planted in open area. ④1/2 of each leaf should be cut before planting if some fineroots are damaged. ⑤Good irrigation and fertilization condition are needed for the growth of C. polyanthum seedlings, and the major limitation of the plantation is low temperature the plants will die if the temperature is under 0℃ for continuous 7 days. We conclude that C. polyanthum can be planted in the mountainous areas characterized by semi shade or shade slope at 500～1 000 m above sea level to the north of the tropic of cancer, such as Southern Yunnan, Southern Guangxi and the whole Hainan Island.Calophyllum polyanthum is a climax tree species in the tropical rain forest of south Yunnan, China.
