The Bamboo Grove Structure of Phyllostachys aureosulcata f. spectabilis and Ph. Propinqua in Beijing
The grove structure of phyllostachys aureosulcata f.spectabilis and Ph.propinqua were studied at different sites in Beijing.The results indicated that their density was too high,the DBH of most bamboo shoots was too small,the high ratio of old bamboos was too high,and the effective phosphorus in the soil was too low.The DBH of bamboo shoots at most sites were about 2cm,and reached the high yield standard 3.5cm only at the reference site.The density was higher than 80000 shoots per hm2,4-12 times of the commercial cultivation density.Old bamboo accounted for 1/5-4/5 of the bamboo populations and the share of young bamboo shoots was less than 1/2.Therefore,it is urgent to adjust the bamboo grove structure in a planned way so as to improve the forest quality and landscapes.
