摘要

该研究评估了在地面以上0.6-0.9米处切断小型林下山毛榉根系吸盘的机会。在一个封闭的树冠不均匀老化的北方硬木林中，用剪枝剪进行切割六年后（试点测试），91%缺乏剩余活枝的高树桩已经死亡。在那些被砍到最低的树枝上的人中，所有人都活了下来。在后来的一次操作试验中，合同工作人员在选择系统切割前的两个生长季节使用链锯，75%没有剩余活树枝的高树桩在第五年就已经死亡。在最初发芽的最低活枝条下切下的树桩中，只有7%在第六年有活枝条。在最低枝条上方切割的高树桩中，84%存活下来。

Beech shearing/high-stumping to control understory interference

The research evaluated opportunities for cutting off small understory beech root suckers at 0.6-0.9 m above ground. By six years (pilot test) after cutting with lopping shears in a closed-canopy uneven-aged northern hardwood stand, 91% of high stumps lacking a residual live branch had died. Of those cut above the lowest living branch, all survived. In a later operational trial by contract crews using chainsaws two growing seasons before a selection system cutting, 75% of high stumps without a residual live branch had died by the fifth year. Of stumps cut below the lowest living branch and that initially sprouted, only 7% had a live sprout by the sixth year. Among high stumps cut above the lowest branch, 84% survived.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
