水杉苗截根移栽研究

A study on transplantation of Metaseqoia giyptostroboides

研究表明,实生苗采用截干方法移栽有利于提高栽植效果,尤其是冬季截干,成活率可提高30％,春芽萌动提早5天,发芽高峰期提早12天,全年新梢生长量增大24.72cm。截干处理还有利于提高苗木质量。

With the trunk cutted,thirty percent of seedlings in Metasequoia giy-ptostroboides could be survived, especially during winder,also the spring bud of it could sprout five days earlier, the new sprouts increment an year increased 24.72.
