摘　　要：以1年生的木荷苗木为材料,分析超级苗选择方法与标准,并通过超级苗造林,促进木荷人工林的速生丰产。结果表明:(1)超级苗选择按苗高、地径同时加1.0δ,入选率12%,入选超级苗苗高≥96 cm,地径≥1.1 cm;(2)13年生木荷超级苗造林林分胸径年均生长量、树高年均生长量均表现优异,材积累积速度较快,达到年平均树高生长量0.85m,年平均胸径生长量1.03 cm的速生丰产能力。The selection method and standard of the superior seedlings were analyzed with 1-year-old seedlings of Schima superba. The results showed that：（1）superior seedlings were selected by using the average height and average basal diameter add one-times standard-deviation to S. superba superior seedlings selection standard, the selected ratio was 12%, height of superior seedling was ≥ 96 cm, basal diameter was ≥ 1.1 cm;（2）forest annual average diameter growth and annual average height growth for 13 ages of superior seedling of S. superba of afforestation were taken on great significant differences, volume accumulation speed was faster, annual average diameter growth was 1.03 cm, annual average height growth was 0.85 m.
