The main root of Toona sinensis bred by sowing method is obvious and the growth is exuberant. Before sowing, the seeds should be soaked in water at a temperature of 20 ℃-30 ℃ for 12 hours.

The cuttings after treatment are deeply cut on the sand bed. In order to keep the temperature at 25 ℃-30 ℃) and humidity, we can cover the cuttings with transparent plastic cloth.
