摘　　要：为了探索适宜的乌桕采穗圃的经营方式,分别以嫁接部位与修剪程度、栽植密度和施肥处理为试验因子,采用双因素完全随机区组试验设计,在1年生乌桕采穗圃内,就其对穗条生产的影响情况开展了两项试验。结果表明:采用春季于距分枝点10 cm处嫁接、夏季在枝条15 cm处修剪的经营方式,能生产较多较优质的穗条;栽植密度宜为50 cm×100 cm;经营期可适量施用氮肥和磷肥,尽量少用或不用钾肥。In order to explore reasonable management style of cutting orchard in Sapium Sebiferum,two tests of scions production were carried out in one-year-old S.Sebiferum cutting orchard,taking grafting place,pruning degree,planting density and fertilizer application as the tested factors,using double-factors completely random block design.The results showed that the method of grafting at 10 cm branch in spring and cutting at 15 cm branch in summer could increase the yield of high-quality scions,and the best planting density was 50 cm×100 cm.Appropriate N and P fertilizers should be applied in management period except K fertilizer.
