互叶白千层景观树修剪措施与效果分析

Pruning Measures and Effect Analysis of Alternate Leaf and White Melaleuca Landscape Trees

分析了互叶白千层不同定干高度、不同修剪方法的体量性状、三维绿量、消光值、透光系数、透视率的变化及其差异性。结果表明:互叶白千层通过定干、修剪等技术措施可以培育具有美感观赏价值的规整球形景观树,体量性状规整,树态典雅,枝叶浓密且集中分布。通过对比试验认为采用齐地截干,分别在每年8月、9月和10月各修剪1次,加上休眠期修剪1次的K0S3D处理,和采用齐地截干,分别在每年4月、5月和6月各修剪1次的K0S3C处理较为合适,经营效果较好。

The changes and differences of volume characteristics,three-dimensional green quantity,clipping value,transmittance coefficient and perspective of Melaleuca alternifolia different fixed tree height and different pruning methods were analyzed.The results showed that the regular spherical landscape trees with aesthetic and ornamental value could be cultivated by fixing the trunk and pruning of Melaleuca alternifolia,with regular volume,elegant tree form,dense branches and leaves and concentrated distribution.Through comparative experiments,it is considered pruning once in August,September and October,plus K 0S 3D processing with one dormant pruning,and the K 0S 3C pruning once in April,May and June are more suitable and the operation effect is better.
