| 摘 要： | 节痕是影响杨木质量的最主要因子。有效地控制杨木节痕和减少虫眼是提高杨木质量的关键技术之一。研究表明:整枝、控制虫眼和科学造林是提高杨木无节化程度的重要措施。可根据加工工艺要求, 采用等高整枝或等径整枝。加强对天牛的预防是减少杨木木材虫眼的重要手段。若发现天牛危害, 采用甲胺磷原液注射或用40 %氧化乐果药棉堵塞。引进抗虫能力强的杨树优良无性系, 采用多无性系造林、萌蘖造林和2 根1 干苗造林, 可以大大提高杨木自然无节的比例。图1 表2 参4

| Abstract: | Nodal scar is the most important factor affecting timber quality of poplar .It is one of the key techniques of improving timber quality of poplar to effectively control the nodal scars of stem and decrease the numbers of insect hole .The results indicate that pruning (pruning in equal height and pruning in equal diamater), controlling insect hole and scientific forestation are important measures to enhance the non-nodal degree of stem.Strengthening prevention and control of long-horned beetles is a way of decreasing numbers of insect hole .Therefore , many plus clones with worm resistance should be introduced in forestation .Planting by suckers and planting by stock with twoyear- old root system and one-year-old stem should by popularized in order to increase the natural non-nodal proportion of poplars. |
