Introduction & Extension Of Bambusa Pervariabilis×Dendrocalamopsis Oldhami No.3

On the base of analyzing the industry transition of Chuannan forest bureau, construction of "6 forest projects "of china and eco-environment, social economy sustainable development strategy, this paper introduced 1-year stem-cutting shootings from Liuzhou Forest Science Institute of Guangxi province to trial farms of Daxing village of Jianwei county ,Leshan city; Yangwan, Leshan city; Fuxi town of E'meishan city; Shuikou town of Shawan district; Tongxing village of Jinkouhe district respectively. It was indicated that Bambusa pervariabilis X Dendrocalamopsis Oldhami No.3 had been introduced successfully. It could grow normally in the areas of where the altitude is under 1000m, and it's survival rate, preserving rate, grow speed, economic effect were superior to local dominate bamboos species -Neosinocalamus affinis. It was difficult to extend to semi-arid-heat vale areas for high price, low production and high cost, although it can grow and as be one of eco-restoration tree species. The bamboo shooting's rate is 99.6% in the trial area, beyond to Neosinocalamus affinis and only below to that in original. Meanwhile, this study have probed into technologies of quickly multiplication and seedling management, and i nferred a s eries o f m ultiplication & c ultivation t echnologies o f i ntroducing Bambusa pervariabilis X Dendrocalamopsis Oldhami No.3 in the trail area, and propagated amounts of seedlings by cutting and sprouting. The introduction of Bambusa pervariabilis X Dendrocalamopsis Oldhami No.3 take a very important role in impulsing eco-environment construction and social economy development in this area.
