Vertical distribution prevalent in the high altitude of 700-800 meters below the hilly and plain. Teak is a tropical species, require a higher temperature. Average annual temperature of origin for the 20 ℃ -27 ℃, the absolute temperature 2 ℃, annual precipitation 1100-3800 mm, wet and dry season significantly. Strong positive species, can grow in sandy shale, granite develop into the red soil and red earth, the hi rich, moist, fertile, well-drained soil. No frost in the low temperature (-1 ℃ -2 ℃), planted in sheltered places. Teak grows fast, strong bud, coppice after cutting. The growth of the best stand on Hainan Island, 10 years old ago, the average annual growth of 1.5 meters high, 1.6 cm in diameter; general stand height growth also has 1 meter, about 1 cm in diameter. 

 Second, seed sowing. 

 Seed species in the 1-2 month brown or light brown shell fruit ripening. Taken back to the fruit, the calyx persistent capsule will be removed, dried, bags possession. 750-100 grams of grain weight, germination rate of 50% -80%. Drying method with a dip before planting germination, the seeds were spread on the concrete floor drying, the surface temperature is highest in the afternoon, put away the seed into cold water overnight, and repeatedly dip the sun for a week to seed. This method results in higher temperatures well. First broadcast, planting about 100 per square meter.

 Third, transplant seedlings planted. 

 3-5 cm in height when two true leaves, into the container bag cultivation, 30-40 cm in height can be Chupu afforestation. Planting hole-like site preparation, point size 50 × 50 × 40 cm, 100-250 grams per fertilizing fertilizer as base fertilizer. Planting density conditions at the site a better platform, plains, plants per hectare 1050-1200; Mountain Site good 1200-1350 plants / ha, spacing of 3-4 meters. 

 Fourth, mixed forest. 

 Teak Leaves large, pre-fast, without shade, without a large initial planting density, preferably mixed planting, choose tree species associated macclurei, Schima superba, Castanopsis hystrix, bayberry, cypress and other construction, mixed 1:2 ratio of grapefruit -3 other associated trees, evenly mixed between the irregular methods opened.
