Abstract:

Based on the comprehensive and longterm survey of Cinnamomum japonicum var. chenii，the paper described its natural distribution，habitat and regeneration condition，and other morphological and ecological characteristics. After a series of longer term experiments，a complete cultivation technique system was established，which concluded seeds collection，seeds treatment，seeds storage，sowing，cutting，container cultivation，transplanting，seedling management and afforestation techniques. The key cultivation techniques were seed stratification under wet sand and shading young seedlings with the shading net. For cutting propagation，the cutting was better cut from the main branches with heel，and should be treated with 100 mg·L^-1 ABT1 rooting powder，with intermittently spraying mist of water and shading from the sunshine. The big seedlings for gardens can be cultivated with several transplantations. A average height of six year old seedlings reached to 280 cm with the highest 350 cm，and the average diameter at breast height was 3.04 cm，with the most of 3.91 cm. The survival rate was able to reach 95% when the 3year old contained seedlings were planted. Therefore，the container cultivation technique became a new method for planting the species in poor areas on islands.
