摘　　要：为解决朱顶红种球自产及花期调控提供参考。通过对进口朱顶红商品球和二年生播种苗进行生长动态的比较,探讨朱顶红播种苗与商品球的生长习性。开花商品球的叶面积远远大于二年生播种苗的叶面积,在4月-9月间一直在增加,9月初达到高峰。2年生的播种苗8月叶面积最大,9月淤滞持平,10月开始凋落。进口成品球叶片7月达到最多,9月开始降低。二年生播种苗的叶片8月以前一直增长,商品球和二年生播种苗最终叶片数分别为10和8。从叶片存在的时间分布来看,成品球叶片存在的时间长于二年生的叶片。朱顶红幼苗与成品球的生长发育存在一定的差别,国产杂交苗经过两年的生长就可以成为商品球。The study was to supply references for bulb self-production and flowering control of hippeastrum.Through the growth dynamic comparison of commodity bulb of imported hippeastrum and 2-year-old seedling,their growth habits were discussed.The leaf area of flowering commodity bulb was much larger than that of 2-year-old seedling,all with increased from April to September and at its peak at the beginning of September.The leaf area of 2-year-old seedling was largest in August,stable from September and the leaf started to fall in October. The leaf area of imported product bulb got largest in July and started to reduce from September, The 2-year-old bulb was all through increasing before August. The finally formed leaf numbers of commodity bulb and 2-year-old seedling were 10 and 8 respectively. As for the time distribution of leaf existence, the existence time of product bulb was longer than that of 2-year-old seedling. There was some difference between the growth and development of hippeastrum seedling and product bulb and the domestically produced hybrid seedling could grow into commodity bulb after two year growth,
