Techniques for Seedling Cultivation of Corylus heterophylla×Corylus avellana with Upright Twig and Lamination

平欧杂种榛传统的压条育苗技术方式是利用结果母树进行育苗,不仅出苗率低,而且壮苗数量少。利用建苗圃的育苗方式进行压条育苗,可以将一些等级低的苗木利用起来,而且育苗数量逐年增加,Ⅰ级苗率达85%以上。文章从育苗圃地选择及规划、母株定植与管理、压条育苗技术等几个方面总结了平欧杂种榛嫩枝直立压条育苗技术,为相关从业者提供技术指导。

The traditional layering seedling cultivation technique for Corylus heterophylla×Corylus avellana is to use fruiting mother trees for seedling cultivation,which not only has a low emergence rate but also a small number of strong seedlings.By using the seedling raising method of building a nursery for layering seedlings,some low-grade seedlings can be utilized,and the number of seedlings is increasing year by year,with a grade I seedling rate is over 85%.The article summarizes the techniques of upright and layering seedling cultivation of Corylus heterophylla×Corylus avellana from several aspects,including the selection and planning of nursery sites,mother plant planting and management,and layering seedling cultivation techniques,providing technical guidance for relevant practitioners.
