摘　　要：以五角枫、火炬树为材料,运用3因素5水平二次正交旋转组合试验设计方法,研究了石质丘陵春季造林中,保水剂、ABT生根粉和基肥3项造林辅助措施对造林成活率和新植幼树生长量的综合作用。结果表明:保水剂、ABT对2个树种造林成活率的促进作用分别达到极显著和显著水平;施用基肥虽然对2个树种造林成活率有显著的不利影响,但对成活后的2个树种幼树生长量都有极显著的促进作用;保水剂、ABT生根剂对五角枫的新梢生长量有显著的促进作用,对火炬树高生长影响则不显著。综合成活率和幼树生长2个目标,经计算机模拟优化得出:保水剂的推荐用量,火炬树为36.8～39.9g/株,五角枫为35.1～39.2g/株;生根剂的推荐使用量,火炬树为31～53.7mg/kg,五角枫为41.9～60.1mg/kg;基肥则以不用为宜。Techniques of afforestation to survival rate and young tree＇s growth increment were tested by the materials of Acer mono and Rhus typhina with the factors including super absorbent polymer, ABT and base fertilizer. The result obtained by the experiment of L9 （3^5 ） orthogonal rotatable central composite design indicated that super absorbent polymer and ABT reached the very significant level and significant level respectively with the survival rate; the base fertilizer took significant effect in growth increment while it had adverse effect with survival rate; super absorbent polymer and ABT took significant promoting effect with growth increment of A. mono＇s new branch while R. typhina not. According to the survival rate and young tree＇s growth increment, optimized by computer simulation, the recommended amount of super absorbent polymer was followed as ： Rhus typhina 36.8--39.9 g per tree, Acer mono 35. 1--39.2 g per tree. The amount of ABT was fallowed as： Rhus typhina 31--53.7 mg/kg, Acer mono 41.9--60.1 mg/kg. Base fertilizer was not recommended.
