【摘要】 作者通过七年的试验证明,亚硫酸盐酒糟醪液采脂其松脂产量比常法采脂增加27.2％;木材生长量比常法采脂少损失5.3％;木材物理力学指标,高于未采脂松树7—18％,而常法采脂基本上不改变松树木材的物理力学性质,不影响木材的利用价值。更多还原

【Abstract】 Results of tapping experiments in the period of seven years on Pinus massoniana using spent sulfite liquor, after alcoholic fermentation and distillation, as stimulator showed that the oleoresin yield was 27.2% higher and the loss of volume growth was 5-3% lower in compare with, those of traditional tapping method. Most physico-mechanical measurements were 7-18% high than those of the untapped trees. Whereas traditional wood tapping method had practically no effect on physico-mechanical properties and utilization of the wood.更多还原
