摘要
以适宜新疆地区种植的彩色树种紫叶白蜡为研究对象,通过低温处理,用电导法测定紫叶白蜡相对电导率,并用Logistic方程拟合求拐点值来估计其半致死温度,探讨其抗寒性。结果表明,紫叶白蜡的半致死温度为-38.9℃,在新疆寒冷的冬季不采取任何措施,紫叶白蜡可安全过冬,是园林绿化兼防护功能于一体的优良树种。
Color species,namely Fraxinus autumn Purple were taken as research objects that are suitable for cultivating in Xinjiang region. Relative conductivity of Fraxinus autumn Purple was determined by conductometry under low temperature. Logistic equation fitting for inflection point value were used to estimate its semilethal temperature and explore its cold resistance. The result shows that semilethal temperature of Fraxinus autumn Purple is -38.9 ℃. Fraxinus autumn, one of the landscaping and protective superior species, can over the winter safely without any measures in cold winter in Xinjiang region.
