摘　　要：为提高尾巨桉(Eucalyptus urophylla×E.grandis)无性系的穗条产量和质量,开展2种不同类型的肥料以及8种不同采穗母株剪顶高度对穗条产量和质量影响的试验,结果表明:在生产中高架沙床采穗圃施用全水溶性肥B效果更好;高架沙床采穗圃尾巨桉无性系采穗母株剪顶的最佳高度8～9 cm,不仅产穗数量多,质量好,扦插成活率也最高。To increase the output and quality of cutting seedlings of Eucalyput urophylla x E. grandis clones, a trial of impacts of 2 different types of fertilizers and 8 different top pruning heights of mother plants for scion-plucking on output and quality of cutting that total water-soluble fertilizer B exerted the best effects seedlings was carried out. The results showed in elevated sand bed orchid. The best top prun- ing height range was 8 - 9cm of mother plants for scion-plucking of Eucalypt urophyUa x E. grandis clones. The cutting seedlings were not only of high output and good quality, but also with high survival rate.
