摘要：心材对木材品质的影响至关重要,其形成受多种内外因素的影响。基于心材形成的管道模型、代谢调控和激素调控理论,文中总结了水分、矿质营养、光照和气温等环境因子及灌溉、施肥、修枝和间伐等抚育措施对心材形成的影响及其内在机制,得出适度干旱、特异矿质元素、充足的光照、高纬度高海拔低温有利于心材形成,科学合理的灌溉、施肥、修剪和间伐等抚育措施能够促进心材形成,并有助于形成高品质的心材;提出当前心材研究存在的不足与展望,以期为今后心材形成机理及人工林心材定向培育理论与技术等研究提供参考。
Heartwood is critical to wood quality,and its formation is influenced by a variety of internal and external factors.Based on the theories of heartwood formation,such as pipeline model,metabolic regulation and hormone regulation,this paper summarizes the effects of environmental factors such as moisture,mineral nutrients,illumination and temperature as well as management measures such as irrigation,fertilization,pruning and thinning on heartwood formation and their intrinsic mechanisms,and concludes that moderate drought,specific mineral elements,sufficient illumination,and low temperatures at high latitude and high altitude are conducive to the formation of heartwood,and that reasonable science-based management measures like irrigation,fertilization,pruning and thinning can promote the formation of high-quality heartwood.The shortcomings and prospects of the current heartwood research are proposed,with a view to providing references for future research on the mechanism of heartwood formation and the theory and technology of directional heartwood cultivation in plantation forests.
