洋紫荆中等规格绿化苗木快速培育技术研究

Study on quick cultivating technology of Bauhinia Variegata for medium standard greening plantlets

利用胸径4~6 cm的小规格苗木,采用地栽模式,经精细化管理培育2.4年,胸径平均达11.9 cm,可出圃应用;利用胸径10~15 cm的规格苗木,采用控根器集中培育1年,经精细化管理,平均胸径达14.6~17.4 cm,达到快速培育目的,适合现代苗木产业发展,具有可观经济效益,可推广应用。

Using the small standard plantlets with diameter at breast height of 4~6 cm, by field-cultivation, after 2~4 years of detailed management and cultivation, the average diameter at breast height grows to 11.9cm. Using the plantlets with diameter at breast height in 10~15 cm, after detailed management and cultivation for 1 year in the root control device, the average diameter at breast height grows to 14.6~17.4 cm, to achieve the purpose of quick cultivation. This method suits for the development of modern nursery industry, has obvious economic benefit, and can be popularized and applied.
