In order to enhance the ornamental effect ,maintain hedgerow shape ,reduce artificial pruning times , thereby reducing the cost ,reducing the potential safety hazard existing in the operation of the pruning of work -ers ,the effect of hedgerow stop on was studied in 2012 .The results showed that :in the north ,the appropriate concentration of hedgerow stop on Ligustrum obtusi f olum Siob was 200 ~ 300 times .3 times annual application could ensure that the annual pruning less than 4 times ,which was half times of the usually year ,and effectively reduced the maintenance cost .The suitable concentration of Long age little leaf lilac was 200 ~ 300 times liquid , suitable concentrations of small age little leaf lilac and tree Caragana were 300 times liquid ,not only making shorten internodes ,but also had no effect on the blossom .Hedgerow stop had obvious effect on different varie-ties of hedge plants ,spraying hedge stop 3 times ,only need trim 3 times in the growth season ,5 times fewer than former years ,and the trees shape kept ideal state ,hedge tidy ,tree branches and leaves thick .For the color variety of trees grafted should do a test first ,then large area promotion ,or with other toner to use .% 为了增强绿篱的观赏性,保持造型,减少人工修剪次数,从而降低成本、降低修剪工人在操作时存在的安全隐患,2012年利用一个生长季对不同的绿篱植物进行了施用绿篱停的试验研究。结果表明：在北方绿篱停对水腊适宜的浓度是200~300倍液。全年施用3次,就可以保证全年修剪次数不超过4次,是常年修剪次数的一半,有效地降低了养护成本。树龄长的小叶丁香适宜浓度是200~300倍液,树龄小的小叶丁香及树锦鸡适宜浓度是300倍液,不仅可使其节间缩短而且不影响开花。绿篱停对供试不同品种绿篱植物均有明显效果,一共喷绿篱停3次,整个生长季只修剪3次,比常年少修剪5次,树木形状保持理想状态,绿篱整齐,树球枝叶茂密。对于嫁接的彩色树木品种应该先做试验,再大面积推广,或者配合其它的增色剂来使用。
