自然分布的风箱果(Physocarpus amurensis )自然更新能力较差。通过对采自风箱果枝条不同部位的插穗采用不同药剂、不同浓度及不同处理时间的扦插试验，研究了风箱果嫩枝扦插的生根效果。结果表明：100 mg L-1 IBA处理5 min的插穗生根效果较好；经100 mg L-1 IBA处理5 min的插穗，其中枝条梢部插穗的生根率最高，达92.22%，中部和下部插穗的生根率差别不大。
自然分佈的風箱果(Physocarpus amurensis )自然更新能力較差。通過對採自風箱果枝條不同部位的插穗採用不同藥劑、不同濃度及不同處理時間的扢插試驗，研究瞭風箱果嫩枝扢插的生根效果。結果錶明：100 mg L-1 IBA處理5 min的插穗生根效果較好；經100 mg L-1 IBA處理5 min的插穗，其中枝條梢部插穗的生根率最高，達92.22%，中部和下部插穗的生根率差彆不大。

The natural regeneration capacity of naturally-distributed Physocarpus amurensis is much poor.Cutting experiments of different aqents,concentration &time on different parts of cuttings for Physocarpusamurensis were conducted.The roooting effcet of softwood cuttings of Physocarpus amurensis were studied.Result shows that :the rooting rate of cutting is greatly improved by treating with 100 mg L-1 IBA for five minutes;the rooting rate of cut-tings of top branch are maximized (92.22%)by treating with 100 mg L-1 IBA for five minutes.The rooting rate of the middle & lower cutting has little difference.
