北海道黄杨引种及快繁技术研究

The Technological Study of Introducing and Progagating Hokkaido Box

通过对北海道黄杨引种和繁育试验,总结出北海道黄杨在我市有两次高生长高峰期,即3～5月份和9月份;同时不同浓度生根粉处理对苗木根系生长及苗木高生长有显著的影响,北海道黄杨嫩枝扦插最适宜的生根粉浓度为100mg·kg-1.

Through the experiment of introducing and propagating Hokkaido box, it is concluded that there are two growth peaks of Hokkaido box in Zhumadian City, namely from March to May and in September;also that different treatment by different concentration of rootage powder （methyl anaphthyl acetate）have remarkable influence on the growth of the root system and high- growth of the little plant.The best concentration of the rootage powder for the cuttage of Hokkaido box twig is 100mg·kg^-1.
