| 概要 |
本報告は,竹林の合理的作業法を見出さんとする意図のもとに設定した試験林の概況と試験方針ならびに方法の概要である.1.試験林は,福岡県粕屋郡久原村の村有竹林内に1953年2月設定したものである.2.竹種はマダケで,試験対象林分の面積その他については第1図に示す通りである.3.試験地の概況は第1表の通りである[table]4.試験方法 竹林の基本的作業種,特に主として採用することについての可能性を検討...する価値があると考えられる前記の6種類について,その林分構成状態の変化を検討すると共にそれらの各種作業法の立地関係・事業運営上の利害得失・経営成果への影響等をもあわせて考察することとした.
This, intended as an advance report, outlines the test forest set up for the purpose of finding effective working methods in the bamboo stands and the plan of testing. 1. The test forest was set up in the village-owned bamboo forest in Kuhara-mura, Kasuya-gun, Fukuoka Prefecture, in February 1953. 2. The bamboos are MA-DAKE's (Phyllostachys reticulata C. Koch), and the area under test is as shown in Fig. I. 3. The general condition of the test area is given in Table I. 4. Method of testing: The fundamental working systems in bamboo stands, particularly the following six types of systems mainly employed in Kyushu District, are to be investigated by means of volume production as the measure, and the orientation, relative merits in operation, differences in management results and other factors are also to be studied. Working Systems in Bamboo Stands A, Block Working 1. Clearcutting with Natural Reproduction by Self-sown Rhizome a) Whole stand clearcutting b) Clearcutting in strips i Alternate strips method…(1) ii Progressive method c) Spot clearcutting 2.
