银杉(Cathaya argrophylla)为我国一级保护珍稀植物,由于其自然繁殖能力弱而使得本身就已十分稀少的种群数量难以扩大。本文通过对金佛山野生银杉的扦插繁殖试验说明,经100ppmABT9号生根粉和500ppmJH强力生根剂处理的插穗,在春、秋两季扦插都可获得成功,最高成活率可达13%。 Cathaya argrophylla (Cathaya argrophylla) is the first grade protected rare plant in our country. Due to its poor natural reproduction ability, Cathaya argrophylla makes it difficult to expand its own population. In this paper, the experiment of cuttings propagation of wild silver fir in Jinfo Mountain showed that the cuttings treated with 100ppm ABT9 rooting powder and 500ppmJH strong rooting agent could succeed in spring and autumn. The highest survival rate could reach 13%.
