Effect of Different Management Patterns on Leaf Characteristics and Shoot Yield of Phyllostachys heterocycla ‘Pubescens’

To investigate the effects of different management patterns on leaf characteristics and shoot yield of shoot-use Phyllostachys heterocycla ‘Pubescens’ forest, soil and plant analyzer development value (SPAD) ,leaf area index (LAI) , and bamboo shoots yield in the next spring were investigated and analyzed under four management patterns (clear cutting band, layer transformation, adding transported soil,conventional management) The results showed that SPAD values increased at first and then decreased，LAI did not change significantly. The SPAD value and LAI of D3 (1 m strip, clear some bamboo rhizome of standing bamboo)treated in mechanized strip management model were higher than artificial management, and LAI was significantly higher than mechanized layering and adding guest soil management. The SPAD value and LAI of C2 (clear bamboo rhizome of 0~25 cm soil depth )treated in the layered management model are lower than other treatments in the same period. The processing of D3 treated and T6 (guest soil is 6 cm)treated in the mechanized management mode is the highest. it had evident positive relation of SPAD value, LAI and shoot yield under different treatment.
