Abstract:: The 3-year-old Toona sinensis, which was planted by regime of uneven row spacing，was served as experimental materials to trail the experiment of the fertilization with watering control and cutting-stem effect of these three factors on the sprouting and its vegetable output of Toona sinensis under applied the L9(34) orthogonal design.The results showed that it was beginning sprouting after 7 days of implemented the trail with mean sprouts of 4.1-7.7 and branches of 1.4-2.2 per stem，respectively.There were 2.8-4.0 mm，3.5-8.3 cm and 2.9-4.2 mm，4.0-9.0 cm of sprouting diameters and lengths of T.sinesis，respectively，after trail implemented for 50 days and 70 days.For 70 days of the experiment carried out，total output and value of sprouting vegetable were 661.3-3 161.8 kg/hm2 and 13 225.2-63 236.0 RMB/hm2，respectively.It was presented significant differences of sprout growth and sprouting vegetable yields between treatment combinations with pivotal factor of organic fertilizer influencing these two parameters.The optimal treatment combination of the highest sprouting vegetable yield was organic fertilizer 0.25 kg/stem with 20 cm cutting-stem and watering once every 4 days.
