日本落叶松混系扦插苗造林应用初步研究

Study on Mixed Cutting Seedlings Afforestation of Larix kaempferi(Lamb.)carr.

为了探索日本落叶松扦插造林效果,笔者利用9 a生的生长数据对建始县高岩子林场的日本落叶松混系扦插苗造林试验林进行了分析。日本落叶松混系扦插苗与实生苗造林成活率、保存率差异不大,但胸径、蓄积之间存在极显著性差异,树高之间存在显著性差异,日本落叶松混系扦插苗胸径、树高、蓄积分别是实生苗的1.16,1.10,1.39倍。混系扦插苗大多来源于本地苗木的优株。

In order to get afforestation effect of Larix kaempferi（Lamb.）carr.,the authors analyzed its 9-year old growth data in Gaoyanzi Forest Farm.its cuttings mixed with the seedling survival rate,preservation rate is insignificant,but between diameter and accumulation have significant difference as well as height,department of Japanese larch cuttings mixed with DBH,tree height,accumulation seedlings were 1.16 times,1.10 times,1.39 times.Most of mixed cuttings were from the local superior plant.
