摘　　要：根据攀枝花荒山造林需要,为培育出优质毛红椿壮苗,开展毛红椿幼苗肥水试验,探讨肥水管理对毛紅椿育苗的影响。结果表明:水肥控制对毛紅椿苗期生长有明显的促进作用。毛紅椿幼苗对水肥控制试验组合的反应是不同的。各个水肥控制试验处理间苗高和冠幅差异不显著,而施肥次数和施肥次数与灌水次数间的交互作用苗木地径差异显著,其中施肥次数影响最大,其次为施肥次数与灌水次数间的交互作用,最优组合为施肥.灌水1次·周-1。To cultivate strong seedlings for the afforestation in the barren mountains of Panzhihua,,the water and fertilizer control experiment was conducted to discuss the impact on seedlings of Toona ciliata var. pubescens. The results showed that water and fertilizer control significantly promoted the growth of seedlings. The response of the seedlings to the combination of water and fertilizer control experiments was different. There was no significant difference in seedling height and crown width under different treatments of water and fertilizer control. But there were significant differences in the seedling ground diameter between fertilization frequency and interaction of fertilization and irrigation frequency,of which fertilization frequency had the greatest impact,followed by interaction between fertilizer frequency and irrigation frequency. The best combination was fertilization and irrigation once a week.
