为解决生产中杜仲良种嫁接苗受季节限制造成的短缺矛盾,在20余年研究基础上,建立了杜仲温室快速育苗关键技术。从冬季播种时机、幼苗越冬温度调控、砧木苗水肥管理、良种嫁接、嫁接后管理、延长生长期等一系列关键节点展开研究,实现了杜仲当年育苗、当年成苗的生产目的。本研究切实解决了实际生产中杜仲良种苗木短缺的技术瓶颈,为杜仲良种苗木推广和产业化发展提供有力保障。
In order to solve the contradiction caused by the seasonal limitation of grafted seedlings of Eucommia ulmoides during production, based on the research of more than 20 years, the key technologies of Eucommia ulmoides seedling in greenhouse were established. A series of key nodes such as sowing timing in winter, winter temperature control of seedlings, water and fertilizer management of rootstock seedlings, grafting of elite seedlings, management after grafting, and prolongation of growth stage were studied to achieve the purpose of nursery seedling in Eurasia and seedling production in that year. This study effectively solves the technical bottleneck of Eucommia seedlings shortage in actual production, and provides a powerful guarantee for the promotion and industrialization development of Eucommia seedlings.
