大岛樱引种和扦插繁殖生产试验研究

都江堰市1993年8月首次从日本引种大岛樱后，经5a引种栽培试验，其年均高1．6～2.0cm，每株产符合规格的叶片达100片以上。采用嫩枝扦插可扩大苗木数量。在生产上，合理施肥，防止积水，预防病虫害，能促进大岛樱叶的生长。

A preliminary Study of Introduction,Cuttage and Generation Production of Prunus donarium

Prunus donarium grow originally in Japan. It is though that Prunus donarium can grow well at warm and humid climate. In August 1993,Prunus donarium was introduced first time to Dujiangyan,through introduction and cultivation for 5 years, the average height annually reaches 1. 6 - 2. 0 cm, more than 100 leaves can be harvested from each tree of Prunus donarim per year. The numbers of Prunus donarium could be increased by cuttage generation. Several feasible methods,such as applying fertilizer,avoiding inundation,preventing diseases and insect pests,can promote leaves growth of Prunus donarium.
