从川滇桤木漂浮育苗材料及准备工作、播种、苗期管理、炼苗、栽植、效益分析等方面探讨了漂浮育苗技术在川滇桤木繁殖中的应用。通过对川滇桤木漂浮育苗与常规育苗的比较,得出川滇桤木漂浮育苗是一种比常规容器育苗成本更低、更省工时且便于管理、育苗周期短,土地利用率高、移栽成活率高的技术,适宜更广泛的推广应用。 This paper discussed the application of floating seedling raising technology in the breeding of Alnus chingii from the aspects of float nursery stock preparation, sowing, seedling management, seedling cultivation, planting and benefit analysis. By comparing the floating nursery stock and common nursery stock of Alnus cremastogyne, it was concluded that floating nursery stock of Nucifera angustifolia was a lower cost than that of conventional container, more labor-saving and easy to manage, shorter cycle of seedling emergence, higher land use efficiency and transplanting High survival rate of technology, suitable for wider application.
