江河滩地优质大径杨木培育关键技术研究

STUDIES ON KEY TECHNIQUES FOR CULTURING FINE LARGE TIMBER OF POPLAR IN FLOOD LAND

大径材的缺乏 ,已严重制约了我国胶合板等相关工业的持续发展 ,如何利用我国东南沿海丰富的江河滩地资源营建大面积杨树优质大径材基地 ?作者通过近 10a的研究 ,就充分利用江河荒滩等劣质土地培育优质大径杨木 ,在进行产业化培育过程中对新无性系引选、主要立地制约因子、密度与林分工艺成熟年限、边行“优势配置式”造林、复合轮伐期经营、节痕控制技术、合理轮伐期确定及配套优化栽培模式等技术关键进行研究总结 。

Shortage of large timber of Popular has seriously restricted the sustainable development of plywood and its relative industry. By ten years' research on how to utilize the abundant resources of flood land in Southeast Coast to build large area bases of large timber of poplar, some key techniques were proposed, such as introduction to new clones, main site restriction factors, density and technical maturation period of stands, compound rotation management, control of nodal scar, determination rational rotation and optimization of culture pattern, which would provide scientific basis for building large area bases of fine large timber of poplar.
