摘　　要：对胡桃楸种子萌发及幼苗的生长规律进行深入研究的结果表明,胡桃楸种子经层积混沙埋藏法处理后,在播种前给种子增温增湿可以提高种子的出苗率(最高达70%),胡桃楸1年生幼苗的地径、苗高主要生长期在6、7月份,苗高在8月下旬停止生长,地径在9月上旬停止生长。应在6、7月份要做好抚育管理、施肥、病虫害防治等工作,促进苗木生长。Study on seed germination and seedling growth of Juglans mandshurica,the data analysis showed that after the seedlings of Juglans mandshurica were treated by layering and sand burying,the seedling rate can be increased by increasing the temperature and humidifying the seeds before sowing(up to 70%),the ground diameter and seedling height of 1a juglans are mainly grew in June and July,the seedling height stopped growing in late August;the ground diameter stops growing in early September.In June and July,we should do a good job in tending management,fertilization,pest control,etc.to promote seedling growth.
