一、生长规律(一)具有较广的生态幅长白松的自然分布区,虽只限于长白山北坡一块面积不大的狭长地带,气候土壤条件似无显著变化,但是引种栽培区域较广(见表1)。(二)速生的生态相对性通常认为长自松是一个速生树种,但仔细观察与进一步分析,这种笼统的说法不妥。长白松在不同立地条件下,其生长状况区别较大(表2)。从这里也可看出它对气候、土壤等条件的适应程度。白城地区万宝与哈拉毛都由于土壤条件这一主导因子的不 First, the growth pattern (A) with a wide ecological breadth White pine natural distribution, although only limited to the northern slope of Changbai Mountain a small strip of land, climate and soil conditions seem to be no significant change, but the introduction of cultivation of a wide area (see Table 1). (B) the ecological relativity of fast-growing Usually considered as a long-term self-prickly tree species, but careful observation and further analysis, this general statement is not appropriate. Changbai pine in different site conditions, the growth difference between the larger (Table 2). From here you can see its adaptation to climate, soil and other conditions. Baobo area Wanbao and Hala Mao are due to soil conditions, the dominant factor is not
