杉木连根采掘试验研究

An Experimental Study of the Fulling up a Tree by Roots of Chinese Fir

本文通过对杉木全树采伐工艺分析和采掘试验研究。结果表明:杉木连根拔树采掘可延长应用主干28cm,造6m材每单株平均可净增产值25.78元,是一种综合利用杉木资源,提高经济效益的有效途径。

The angalysis of the technigue of felling Chinese fir by digging and the experimental studins show that a greater length of 28cm can be achieved for the use of the trunk,and that a net increase of 25.78 Youan on an average for indivedual timber of 6m can be obtained. There fore the uprooting felling method can be regarded as an effective approach to the compre-hensive utilijatiou of Chinese fir resources and to the growth of economic benefit as well.
