摘要
落新妇（Astilbe chinensis）是一类具有观赏和药用价值的野生植物.通过引种驯化试验,旨在研究其生长特性.研究发现,落新妇具有喜肥、抗旱、耐涝、耐寒的特点.在有性繁殖过程中,赤霉素对种子萌发具有显著影响;无性繁殖可以通过切分根茎获得种源;栽培过程中,选择适时打顶可以提高观赏价值.此外,落新妇的主要病害有白粉病,虫害主要有红蜘蛛、尺蛾.
Astilbe chinensis is a kind of wild plants of ornamental and medicinal values. This research aims to study the growth character- istics through domesticated test. The study found that Astilbe chinensis had the features like fertilizer tolerance, drought, water and cold resistance. On the condition of sexual reproduction, Gibberellin had significant effect on seed germination; and in vegetative propaga- tion, the provenances were obtained by method of cutting rhizome. During the cultivation, cutting tip pruning in appropriate period can prove the ornamental value. In addition, the main disease of Astilbe chinensis is powdery mildew, and pests are spider mite and geometrid moth.
