峨眉冷杉(Abies fabri)是我省特有的树种。峨边县是蛾眉冷杉主要分布地区之一。面积占四川峨眉冷杉总面积的37.8％,蓄积占20.2％。峨眉冷杉具有耐寒、耐湿、耐荫等特性,多属藓类箭竹冷杉林型。峨眉冷杉林以成熟,过成熟林为主,面积占该群系的87％,蓄积占94％,平均年龄120—180年,与其他冷杉林比较,其生长速度较快,成熟年龄早,结实周期较长,结实量小,给人工更新用种造成了一定困难。因此,建立母树林基地是加快峨眉冷杉更新速度,提高更新质量的重要措施之一。为此,笔者对川南林业局蛾眉冷杉母树林的生长情况进行了调查。
Abies fabri (Abies fabri) is a unique tree species in our province. Ebian County is one of the main distribution areas of Aberdeen. Area of Sichuan Emei fir the total area of 37.8%, accounting for 20.2% of the accumulation. Emei fir with cold, moisture, shade and other characteristics, mostly moss bamboo spruce forest type. The mature Emeian fir forest is dominated by mature and mature forests, accounting for 87% of the total area and 94% of the fauna, with an average age of 120-180 years. Compared with other fir forests, its growth rate is relatively fast, its mature age is earlier, Long cycle, a small amount of fruit, to use artificial updates caused some difficulties. Therefore, the establishment of the mother tree forest base is to speed up the regeneration of Fir fir, improve the quality of one of the important measures. To this end, I conducted a survey on the growth of Fritillaria moth forest in South China Forestry Bureau.
