摘要
紫椴(Tilai amurensis Rupr)在林内分布数量较少,更新与无性系繁殖比其他树种较困难。于1978年在黑龙江省带林业科学研究所,对该树种无性系繁殖进行试验研究。并通过不同时间不同嫁接部位。不同嫁接方法进行研究。结果表明,嫁接成活率由60％提高到95％以上。筛选出成活率在89％以上的“贴接法”应用于生产。在5月9日到5月15日嫁接成活率最高,先在原始林选优建立采穗圃,再在采穗圃采穗嫁接可提高成活率。
The distribution of Tilia amurensis quality is little in stands and reforestation and asexual reproduction is more difficult than other species. Dailing Forestry Institute is engaged in research experiment for asexual reproduction of Tilia amurensis by way of different time, grafting position and grafting method in 1978. The survival rate raised from 60％ to more than 95％. Survival rate of more than 89％, was selected to use in production. The grafting survival rate was the highest on May 9 to 15. Collection scion nursery was set up by selecting excellent trees in natural forest, then collecting scions in nursery can raise survival rate.
