花木修剪应在什么季节进行

植物图片 2019-12-01 17:24

前面已经介绍过，花木的整形修剪有4大目的。依据不同的目的和花木的习性，修剪有不同的时间。

首先是疏剪，它的目的是为了给花木提供良好的通风、透光环境，因此在整个生长期中可反复进行多次。其次，对于衰老株的更新，其时间可结合冬天或春天的大修剪进行，也可以随时进行。

造型修剪是一件细致的工作，必须一步步将花木攀扎、修剪成目标形态。其时间应以冬天和春天的修剪为主，配合平时对徒长枝的控制。

可爱的桂花

最难掌握的是促进开花结果的修剪。需要因树制宜。修剪时间通常落叶花木在休眠期或落叶后，常绿花木在春天树液萌动时。具体到每种花木又有所不同。春天先开花后长叶的花木，如桃花、迎春、梅花、玉兰等，花芽是在头年的新生枝条上长成的，所以要在开完花后的春天进行修剪，促进萌发新梢。冬天再剪，就会把花芽剪掉。夏秋开花的菊花、茉莉、桂花等，花芽多长在当年的新梢上，所以应在冬天修剪，促其春天发壮芽。耐寒的花卉如月季、石榴、小叶黄杨等宜在晚秋、初冬强剪。耐寒性差的花卉如米兰、一品红等，应在春天修剪。另外，一些花卉在园艺上为促进其一年开多次花，在整个生长期中，都可以在花开过后马上修剪，并配合施肥促进其再一次开花，如月季。
