Effects of Planting Density and Stumping on the Burgeon Yield of Vegetable Toona sinensis

The burgeon of Toona sinensis was considered as a kind of excellent forest vegetable, having rich nutritional value. Studies were made of the influence of planting density and stumping method on the vegetable toon production in order to provide certain guiding basis for the efficient cultivation technique. The results showed that ① there was a fast-growing stage during 2~6 years of age and the production was more than 200 kg per 0.067 hm² during the stable production period since the 7th year. ② The burgeon production under different planting density was 200 kg~250 kg during the stable production period. ③ Stumping significantly increased the branch numbers and improved the harvest efficiency of burgeons, but there was little effects on the burgeon prodution of individual plant.
