Abstract: In order to promote the development of Toona sinensis industry of Yunnan province, two years Toona sinensis were used as materials in the middle of Yunnan province to study the effect of truncation heights, environmental conditions on the germination characteristics and the effect of picking frequencies, picking burgeon lengths on the yield of Toona sinensis by using twoway analysis of variance. The results were as follows: in the same environment (greenhouse), the total bud numbers of 80cm truncation height is about 15 times as many as 60cm truncation height. In the same truncation height (80cm), the total bud numbers in the greenhouse is about 18 times as many as the outdoor. What′s more, compared with the outdoor, the yield was high and the buds mature cycle is short. In the technology of picking Toona sinensis in Greenhouses, the effect of 70cm and 80cm truncation heights on the yield of Toona sinensis was not significant. The effect of picking frequencies on the yield of Toona sinensis was extremely significant. Which picking every 20 days, the yield is highest. And when picking 15cm burgeon length, the yield is higher. However, the interaction of picking frequencies and picking burgeon lengths is not significant.
