以吉林省露水河林区灯台树野生群体为材料,采用样地调查法对其种质资源进行初步调查与分析,结果表明:在3个样地中,以下坡位3号样地生长的植株最多,密度可达349株·hm-2,其中以胸径5~10 cm植株占优势,密度为207株·hm-2,并生长有胸径30 cm、树高16.7 m高大个体。中坡位2号样地密度也较大,为277株·hm-2,而且天然更新极好,幼苗幼树密度为214株·hm-2。在上坡位1号样地中,单位面积密度亦达到149株·hm-2。该林区林地坡度较大地段针阔混交林或杨树纯林是野生种群最为适宜的立地生境。野生植株生长发育正常,无林业有害生物与冻害危害。
Taking the wild population of Dengtao tree in Lushuhe forest area of Jilin Province as the material, the germplasm resources were investigated and analyzed by the sample survey method. The results showed that in the three plots, With the highest density of 349 plants · hm-2. Among them, the plants with the diameter of 5 ~ 10 cm were dominant, the density was 207 plants · hm-2, and the height was 30 cm and the tree height was 16.7 m tall. The density of Zhongzhong2 was also 277 plants · hm-2, and the natural regeneration was excellent. The seedling sapling density was 214 plants · hm-2. In the sample of uphill bit No. 1, the unit area density also reached 149 strains · hm-2. The forest land with a large gradient of coniferous and broad-leaved forest or pure poplar is the most suitable habitat for the wild population. Wild growth and development of normal plants, non-forestry pests and damage hazards.
