川南不同海拔地段麻竹抗寒性分析

An Analysis of Cold Resistance of Dendrocalamus Latiflorus Munro at Different Altitudes

通过在麻竹适生栽培区不同海拔高度低温冻害的典型调查,分析得出麻竹为典型热性竹种,对低温敏感;在1月平均温度低于6℃,极端低温低于-2℃地方易遭受低温冻害,可能造成严重损失;在四川南部地区,麻竹适宜栽培的海拔高度在500m以下。

Through typical investigations of the low-temperature freezing damage in the bamboo suitable cultivation areas at different altitudes, it is concluded that Dendrocalamus latiflorus Munro is a typical hot bamboo species and sensitive to low temperature. It is vulnerable to low-temperature freezing injury in areas with the average temperature below 6℃ and extreme low temperature below -2℃ in January, perhaps resulting in serious loss. In the southern part of Sichuan, suitable areas for cultivation of Dendrocalamus latiflorus Munro are below 500 m above sea level.
