In order to prolong the supply period and increase the economic value of Toona sinensis, the protected cultivation of T. sinensis was carried out on mountainous slope to achieve stagger-season planting and the year round supply. The results showed that in late October to mid-November, the temperature was moderate (1-10℃) and suitable for the lifting of seedlings and temporary planting dormancy. The line spacing of rooted seedlings in greenhouse was （22-24） cm × （4-5） cm and planting density was 900 000-1 200 000 seedlings/ha. The line spacing of seedlings was (14-13) cm ×( 3-4 ) cm and planting density was 1 950 000-2 100 000 seedlings/ha. T. sinensis began to sprout at 8-10℃ and stretch at 10-12℃. When the temperature was stable at 14℃ or above, T. sinensis started bolting and emerging leaves. The terminal buds sprouted in 40-50 d for the T. sinensis planted in greenhouse with the day temperature of 15-22℃ and night temperature over 10℃; the terminal buds sprouted in about 15 d for those planted in the greenhouse with day temperature of 20-25℃and night temperature over 10℃. T. sinensis could be picked 3 times when planted in greenhouse, and the yield was about 24 720 kg/ha.
