Manchurian fir (Abies holophylla maxim.)

用法例句

In order to serving to introducing Abies concolor successfully, several index representing the ability to resist cold and drought was surveyed, in simulated condition of cold and drought, using six months old seeding of nine provenances of Abies concolor, and three species of domestic firs: Abies holophylla, Abies fabric and Abies squamata Mast.

本论文以服务于科罗拉多冷杉的引种工作为目的,对科罗拉多冷杉的九个种源半年生幼苗为试材,对其进行了模拟低温和干旱的处理,测定了抗寒性和抗旱性的相关理化指标,并与同样处理下的我国本土冷杉品种辽东冷杉、峨嵋冷杉及鳞皮冷杉半年生幼苗的对应指标作比较分析,用比较结果来估测科罗拉多冷杉在我国的适生范围。
