响叶杨Populus adenopodaMaxim系杨柳科高大落叶乔木,为我省自然分布较为普遍的独有杨属树种。它适应性强,生长快,材质好,是一个有发展前途的用材树种。我所自1978年起对这一树种的采种育苗进行了试验,初步摸索了这方面的一些规律,1982年又进行了采种时间和采种母树对种子发芽影响的研究。材料与方法试验地设在我所喻家溪圃地,位于山坡中下部,海拔600米,东南坡向,土壤为砂岩发育的山地黄壤。苗床高20厘米,宽100厘米,南北走向。
Populus adenopodaMaxim poplar is tall Willow Branch deciduous trees, the province is more common in the natural distribution of the unique Populus species. It is adaptable, fast growing, good material, is a promising timber species. Since 1978, we have carried out experiments on seed-raising and seedling cultivation of this tree species. We have tentatively explored some laws in this respect. In 1982, we conducted researches on the effects of seed-planting time and seed-planting on seed germination. Materials and methods The experiment is located in the garden of Yujia Creek, which is located in the middle and lower part of the hillside. It has an elevation of 600 meters and a southeast slope. The soil is yellow mountain soil with developed sandstone. Seedbed height of 20 cm, 100 cm wide, north-south direction.
