27 Mar A Study on the Methods to Establish the Evergreen Broadleaved Forest on Artificial Slopes
Abstract
造成直後ののり面へ, より遷移の進んだ段階の植生である常緑広葉樹林を導入する手法の検討を目的として, アラカシ小苗の高密度植栽と, 肥料木混植手法を試験した. 植栽後7年を経過し, ほとんどの試験区で樹冠が閉鎖した現在, 小苗密植か大苗疎植より群落としての生育に有利であること, 肥料木混植のアラカシ生育に与える影響は明らかでないか, 盛土のり面での混植は植生量増加の点で好ましいこと, などか判明した.English Abstract
In order to study the methods of establishing the evergreen broadleaved forest, which is a relatively developed vegetation in the plant succession series on artificial slopes of poor sites, we tested the dense planting of Quercus glauca and mixed planting of fertilizer tree (Alnus Sieboldia ). Seven years after planting, tree canopy is almost closed in each plot, and results at present are as follows.
(1) Dense planting of small nursery trees is more profitable than sparse planting of big ones.(2) Effects of fertilizer tree on the growth of Quercus glauca are not clear. but mix planting on the fill-in slopes resulted in a great deal of standing mass.(3) Land treatment (cut or fill) is the most effective factor for the size of Quercus glauca, and initial plant size is less effective.
