摘　　要：[目的]找出深山含笑1年生播种苗的年生长发育规律,培育出优质健壮的深山含笑苗木。[方法]通过深山含笑播种育苗试验,应用有序样本聚类分析法将深山含笑1年生播种苗苗高生长过程分为出苗期、生长期、速生期和生长后期4个时期,分析各生长期生长情况。[结果]从种子发芽出土到6月期间生长慢,7月生长速度中等,11～12月生长较慢甚至停止生长。[结论]根据深山含笑速生期的生长特点,应在速生期的前1个月追肥,并加强水肥管理及病虫害防治。[Objective]The law of growth and development of annual Michelia maudiae Dunn seedling was explored and the high-quality Michelia maudiae Dunn seedling was cultured.[Method]Thesituation of Michelia maudiae Dunn growth in seedling,growth,fast-growing period and the late growth period according to the height of its seedling was studied with the method of accumulation analysis based on the experiment in its sowing.[Results]In theperiod from seed germination to June,Michelia maudiae Dunn grew slowly,in July its growth rat was moderate,and from November to December it was slower growth or even stopped growing.[Conclusion]According to its growth characteristics in fastgrowing period,the topdressing for Michelia maudiae Dunn should be done in one month before fast-growing period and the management of water/fertilizer and the control of pest/disease should be strengthened.
