摘要

在一个有 16 年树龄的杂交杨树（杨树）种植园收获后的一个生长季，对 100 个树丛中的萌芽进行疏伐，以保留优势萌芽；同时保留 100 个树丛作为对比。经过三个生长季后，疏伐过的树丛和未疏伐过的树丛在每一树丛的萌芽总数或优势萌芽的直径方面没有差异。在未疏伐的树丛中，优势萌芽明显更高。不建议在收获后对杂交杨树萌芽丛进行疏伐。

Hybrid Poplar Sprout Clumps: Thinning Does Not Improve Development

One growing season after the harvest of a 16-year-old hybrid poplar (Populus sp.) plantation, sprouts from 100 clumps were thinned to retain the dominant sprout; 100 clumps were left for comparison. After three growing seasons, thinned and unthinned clumps did not differ in total number of sprouts per clump or in diameter of dominant sprouts. Dominant sprouts were significantly taller in the unthinned clumps. Thinning hybrid poplar sprout clumps after a harvest is not recommended.
