粉单竹引种川南的适应性研究

Research on Adaptability of Bambusa chungii in South Sichuan

本文报道了四川长宁世纪竹园粉单竹引种及其气候适生性。分析表明:粉单竹在世纪竹园经历5年复壮后发笋量逐年增加,形态大小保持稳定;并安全渡过2008年冰雪冻害,耐寒能力强于四川盆地内推广的杂交竹、麻竹;粉单竹其材质性能、景观效果方面均表现优良,目前可在相宜(极端最低温高于-5℃)区域大面积推广利用,立地条件改善和经营水平科学化可保证其高产性能。

This paper reported the introduction of Bambusa chungii by Changning Century Bamboo Park in Sichuan and its adaptability to climate. Analysis indicated that B. chungii had the increased amount of shooting after experiencing the 5-year growth and they had remained stable in their shape and size. And they went safely through the extreme low temperature with snow and freezing rain in 2008, showing their stronger cold- resistance in comparison of hybrid bamboo and Dendrocalamus latiflorus Munro. Due to its better performance in property and landscaping effect, B. chungii is suitable to be extended and used in large area of Sichuan with the extremely lowest temperature at -5℃. The site condition improvement and scientific management could ensure its high yield and better performance.
