| 摘 要： | 杨树修枝是杨树速生丰产后期经营管理中一项重要的措施,本文综述了修枝对杨树生长、材质以及林下经济的影响。修枝对杨树树高、材积生长量的影响因树种、立地、修枝强度的不同规律不同;修枝会降低胸径的生长量,提高萌枝数量,但可以提高材质。修枝对材质的影响表现在尖削度减小、节子减少、形数和形率增加等。修枝可以增强林下作物光合作用,促进林下植物生长,提高产量;实践中,修枝强度、起始年龄、修枝季节应因树种而异。目前,对于杨树修枝的研究多为短期的、单方面的,系统综合研究尚需进一步加强。

| Abstract: | Poplar pruning is an important measure in later stage management for the fast growing and high yield.The effects of pruning on poplar growth and wood quality and under-forest economy were reviewed in the paper.Pruning effects on tree-height and volume growth changed with tree species and sites and pruning intensity.Pruning could reduce the growth of diameter,increase the number of sprouted branches and improve the wood quality.Effects of pruning on wood quality were following as：reducing the stem taper and the number of knots,increasing form-factor and form-quotient and so on.Pruning was good for the growth of undergrowth by increasing photosynthesis and promoting growth and increasing productivity.In the practice,Pruning intensity,initiation age and pruning reasons depended on poplar varieties.Presently,the researches on poplar pruning were mainly focused on the short-term effect after pruning and unilateral research.Systematic comprehensive research should be strengthened. |
