Effect of Stump Treatment on Productivity of Phyllostachys heterocycla cv. Pubesence Stand

From November 2012 to July 2015, experiments were conducted on stump cutting with four treatments namely 0, 225, 450 and 675 stumps/ha, in Phyllostachys heterocycla cv. pubescence stands in Anji, Zhejiang province. The result showed that biomass and quality of new bamboos at stands with different treatments increased with intensity of cutting. Stand with cutting intensity of 675 stumps/ha had biomass of new bamboo of 35.4 t/ha, 27.57% more than that of the control, density of large diameter new bamboo （DBH＞10cm）was 1.43 time of the control, and internode length at breast height was 1.8 cm longer than that of the control. The experiments also revealed that stump treatment could significantly improve the quality of medium and small diameter new bamboos.
