摘　　要：为提高南方红豆杉育苗的发芽率并促进其生长发育,采用不同圃地覆盖物、不同基肥、不同遮光度、芽苗移栽与不同播种方式等对南方红豆杉苗生长发育质量做了比较,得出最佳育苗的关键技术是以苗床垫黄心土,播种后覆盖黄心土后再覆盖苔藓,4 000 kg/667 m2 1∶1配比的腐烂猪牛粪加100 kg复合肥(N:15%,P:10%,K:15%,点养分≥40%)为基肥,控制遮光度为85%等,能够显著提高南方红豆杉苗木的生长发育质量。In order to improve Taxus wallichiana var. marirei nursery germination rate and to promote their growth and development, intend using different mulching materials, different base fertilizer, different levels of shading, seedling-transplanting and other planting method to comparison the growth development quality of T. wallichiana var. marirei, draw the key technologies of the best nursery is Seedlings mattress yellow soil, covered yellow soil after sowing, then covered moss again, 4 000 kg/667 m^2 1 ： 1 ratio of rotting pig dung and 100 kg fertilizer （N： 15%, P： 10%, K： 15%, point Nutrient ≥ 40%）, levels of shading on 85%, and so on, can improve the growth development quality obviously.
