Study on Bumper-yield Technique for Bamboo Shoots Stand of Dendrocalamopsis oldhami

Pan Yongchun(Company of Bamboo. Firewood and Charcoal of Fujian Province, Fuzhou 350003)  
In order to study the bumper-yield measures and structure of bumper-yield stand for Dendrocalamopsis oldhami under different sites, three plots were sut up on river's sludge, sand soiil and accumulation loess to carry out fertilization and cultivation experiments. The experimental results showed that: the genera:ion number of rational structure is 1. 3~ 1. 6. The proper culm number per clump showed a dynamic equilibrium to density in various stands with different densiti The reasonable fertilization is the proportion of N: P: K=2: 1: 1 or 3: 1: 1 for applied chemical fertilers. The annual applied compound fertilizer amount is 2~3kg per clump and applied by several times before and during shooting. Earthing, reversing shoots, and irrigation and drainage all are the key manage ment techniques
