摘　　要：鉴于国内对于大规格朴树容器苗全冠移栽的针对性研究不足,通过对苗圃中朴树不同断根时间和断根次数的对比试验,分析各种操作方式对苗木生长势的影响,为大规格朴树全冠移栽提供技术支持。结果表明,休眠期断根比生长期断根能显著增强苗木生长势,多次断根比单次断根在第1年可明显改善苗木生长状况。建议在准备期较长的实际全冠移栽作业中,在树体休眠期提前进行分次断根处理。In view of lack of targeted research on full crown transplantation of large-sized container seedlings of Celtis sinensis in China,two comparative experiments had been conducted on different root cutting time and frequencies of C.sinensis in a nursery to analyze effects of various operating methods on growth and development of seedlings,for providing technical support for full crown transplantation of large-sized C.sinensis.The results showed that root cutting during dormancy significantly enhances seedling growth compared to root cutting during growth,and multiple root cutting treatments could significantly improve seedling growth compared to single root cutting treatment in the first year.It is recommended that in the actual full crown transplanting operation,if preparation period is long,the root cutting treatment should be carried out in advance during the dormant period of the tree.
