日本落叶松原生种质资源及优良林分选择

Selection of Primary Provenance and Superior Stand of Larix kaempferi

摘要:

摘要：以16 a生日本落叶松原生种质资源试验林为研究对象，对生长性状进行分析比较，结果表明：不同种源、林分的胸径、树高和材积、生长量差异均达极显著水平；选择出最适合在中北亚热带高山区栽植“伊那”和“日光”两个种源以及“草津17”、“伊那12”、“伊那18”、“伊那14”四个优良林分。

Abstract:

Abstracts:The growth traits of 16-year-old Larix kaempferi primary provenance test stands were analyzed.The results showed that DBH,tree height and individual volume were significant different between varied provenance and stands.Two provenances“Yina“and “Riguang”with four superior stands “Caojin17th”,“Yina12th”,“Yina18th”,“Yina14th”were selected for central-northern subtropical high mountainous areas.
