过去我局生产木材多采用斧头砍伐,由于伐口过大,伐桩偏高,使许多木材变为废渣废料,白白损失掉,降低了木材利用率。1987年宽滩林场结合经营采伐生产,对传统的采伐作业方式作了改进,即采取斧劈树根降低伐桩后,用弯把锯贴地伐木。此法与斧头砍伐相比,不仅降低了伐桩高度,而且伐口亦大大缩小,从而使过去伐口处变为废渣和干基部变为伐桩的木材都变废为宝,增加了干材长度,出材量平均提高达8％。该场去年仅经营采伐100亩即多生产木材121.51立方米,增收29 968元。采伐方式的这一改进,为次生林经营开辟了一条增加木材产量
In the past, I produced more lumber by using ax cutting. As a result of the excessively large cut-outs, the pile was too tall, turning many of the lumber into waster waste and losing it in vain, reducing the utilization of timber. In 1987 the Broadbeach Forest Farm combined with the operation of harvesting, the traditional method of harvesting operations has been improved, that is, using ax to reduce the stump cut, the saw with curved stick to logging. Compared with ax cutting, this method not only reduces the height of pile cutting but also significantly reduces the number of cuttings. As a result, the wood that has been turned into waste slag and dried base into stumps in the past has turned into waste, adding dry materials Length, the average amount of material increased up to 8%. Last year, the market only operated more than 100 mu of timber, which produced 121.51 cubic meters of wood, an increase of 29,968 yuan. This improvement in harvesting has opened up an increase in timber production for secondary forest management
