凉山州乡土树种的驯化栽植实验研究

Research on the Experiment of Domesticated Plant to the Indigenous Tree Species in Liangshan Prefecture

选择具有较高观赏价值的石楠、连香树、西康玉兰、银杏四个乡土树种,在高海拔的两个区域(布拖县城边的林场苗圃地海拔高度为2385米,普格县螺髻山风景区山门海拔高度为2060米)分别试种,对其生长状况和成活率作调查,发现四个树种均有一定的成活率(成活率分别是西康玉兰25%,连香树22.5%,石楠30%,银杏53%),说明在凉山州进行高海拔地区城市绿化用乡土树种的驯化工作是可以进行的,所选树种是有驯化可能的。

Photinia serrulata, cercidiphyllum japonicum, magnolia wilsonii, and gingko which are of high ornamental value are selected as the indigenous tree species. And then, respectively, they are planted in two high altitude areas （the nursery garden on the edge of Butuo which has 2385 meters high, and the gate Luoji mountain in Puge county which has 2060 meters high）experimentally. Their growing condition and the survival rate are studied. The study shows that all the four kinds of trees can survive to some degree （the survival rate： magnolia wilsonii 25%, cercidiphyllum japonicum 22.5%, Photinia serrulata 30%, gingko 53% ） , which shows that it is available to afforest cities in high altitude areas in Liangshan Prefecture, and it is possible to domesticate the selected tree species.
