冷杉别名衫松、白松。产于我国东北牡丹江流域山区、长白山及辽宁东部海拔800~1300米地带。北京引种后生长良好,河北省塞罕坝亦有引种,生长良好。冷杉具有较强的耐阴性,适应温凉和寒冷的气候。土壤以山地棕壤土和暗棕壤土为主。常在高纬度地区至低纬度的亚高山至高山地带的阴坡、半阴坡及谷底形成纯林。根据冷杉的生物学特征,现将其容器育苗技术介绍如下。湿土土壤施肥。冷杉一般选用1~2株出圃的苗木,根据冷杉前期速生的特点,装罐要早。一般坝上地区在4月中旬至5
Firs alias pine, white pine. Produced in China’s northeast Mudanjiang basin mountains, Changbai Mountain and eastern Liaoning elevation 800 ~ 1300 meters strip. After the introduction of Beijing grow well, also introduced the Saihanba Hebei Province, grow well. Fir has strong resistance to negative, to adapt to cool and cold climate. The soil is dominated by mountain brown soil and dark brown soil. Often in the high latitudes to the low latitudes of the sub-alpine to high mountain shady, semi-shady and valley bottom to form a pure forest. According to the biological characteristics of fir, container seedling technology is introduced below. Wet soil fertilization Fir generally use 1-2 plants nursery stock, according to the characteristics of fast-growing early fir, canning earlier. General dam area in mid-April to 5
