The Extension and Application Experiment on the High-yield Technique of Cavity-injecting Fertilization in Chengdu Area

Neosinocalamus affinis is the main native bamboo species in Chengdu area and the plain of western Sichuan, and also is the largest species of bamboo resources in Sichuan province. At present the degradation of bamboo forests is a realistic problem to agroforestry. In order to increase the productivity of the bamboo forests and promote the industrial development, Chengdu Institute of Landscape Science has firstly imported the high-yield technique of cavity-injecting fertilization from Jiangxi province and applyied BNP to N. affinis strain plexus. The comparative experiment of the same concentration of BNP on N. affinis indicated that BNP could increase the production and rate of bamboo shoots and the production and rate and diameter of bamboo pole forming, and the effects on the former two were more remarkable than others.
