Description
We carried out experiments with the aim of chemi-killing to the various species.
Chemi-killing the low-grade hardwoods by means of sodium chlorate is a new technigue for conversion of the plantation.
Nearly the half of the sawtimber volume in Hikmi College Forest is unmerchant able. Moreover, the major part of the volume is in cull trees and trees of noncommercial species.
At Hikimi College Forest, in order to convert the present stand we have tried chemi-killing by means of sodium chlorate on the various species in Aug. 1957.
Sodium chlorate were applied to some cuts given by a hatchet and the chemicals went up all right along with the sap flow.
The experimental results are shown in Table 1.~Table 4. The withering phenomena were seen after applying sodium chlorate into the tree extended downwards from top to botton.
Rhus sylvestris, Prunus Jamasakura, Meliosma myriantha Carpinuslaxiflora, Zelkova serrata, Ostrya japonica, and Kalopanax septemlobus were easy to be killed chemically within two weeks.
Carpinus Tschonoskii, Zanihoxylum ailanthoides, Cornus controversa, Styrax obassia, Carpinus carpinoides, Cornus Kousa, Cercidiphyllum japonicum, Lindera erythrocarpa, Acer rufinerve, and Quercus myrsinaefolia were difflcult to be killed chemically within two weeks.
Acer palmatum, Fraxinus japonica, and Quercus salicina were difficult to be killed chemically within one year.
Chemi-killing by means of sodium chlorate is an effective method to the low-grade hardwoods.
