摘　　要：为明确武汉地区不同修剪方式对紫薇二次成花的影响,以武汉市园林科学研究院地栽紫薇为试验材料,进行不同修剪试验,测量紫薇二次开花的花序数量、长度及花期。结果表明:轻度修剪(仅剪除花序)可显著增加紫薇二次成花的花序数量,中度修剪(剪除枝条1/2)新生花序数量最少。中度修剪紫薇花序最长,轻度修剪次之,均显著高于对照。随着修剪时间的推后,紫薇二次开花达盛花期的时间由32 d延长至37 d,盛花期由12 d缩短至6 d。合理修剪可促进紫薇新梢萌发,形成更多的花芽,武汉地区在8月初对紫薇进行轻度修剪,二次开花效果较好。In order to identify the effects of different pruning patterns on the reflowering of Lagerstroemia indica in Wuhan area,using Lagerstroemia indica grown in Wuhan Institute of Landscape Architecture as the experimental material,conduct different pruning experiments to measure the number,length of inflorescences,and flowering period of the reflowering.The results showed that mild pruning(only pruning the inflorescence)significantly increased the number of inflorescences,while moderate pruning(pruning 1/2 of the branches)resulted in the least number of inflorescences.Moderate pruning has the longest inflorescence,followed by mild pruning,both significantly higher than the control treatment.With the extension of pruning time,the time for the reflowering of Lagerstroemia indica to reach its peak flowering period has been extended from 32 days to 37 days,and the peak flowering period has been shortened from 12 days to 6 days.Reasonable pruning can promote the germination of new shoots of Lagerstroemia indica and form more flower buds.In Wuhan area,the reflowering of Lagerstroemia indica was better under mild pruning in early August.
