摘　　要：于2022年,在福建省林业科学研究院内,以鹅掌柴、花叶青木(洒金珊瑚)、大花栀子、六月雪等4种立体绿化植物为试验材料,采用不同浓度的多效唑、丁酰肼、矮壮素等3种植物生长抑制剂对其进行灌根处理,比较不同植物生长抑制剂处理对4种立体绿化植物的矮化效果。结果表明,在自然生长情况下,鹅掌柴和花叶青木的景观效果维持度优于大花栀子和六月雪。鹅掌柴和花叶青木对不同浓度的3种植物生长抑制剂均不敏感;多效唑对大花栀子的矮化率最高(57.80%~59.21%),其次是六月雪(38.00%~41.82%)。因此,建议对鹅掌柴和花叶青木采用粗放型管理,对大花栀子和六月雪施用多效唑300 mg·L^(-1)以控制其生长速度,稳定绿化效果。In 2020,four types of three-dimensional greening plants were used as experimental materials,including Heptapleurum heptaphyllum,Aucuba j aponica var.Variegata,Gardenia jasminoides and erissa japonica at the Fujian Academy of Forestry in Xindian Town,Jin’an District,Fuzhou City,Fujian Province.Di fferent concentrations of plant growth inhibitors such as paclobutrazol,daminoz ide,and chlorocholine chloride were used to irrigate the plants.The dwarfing effects of different plant growth inhibitors on the four types of three-dimensi o nal greening plants were compared.The results of this study indicated that unde r natural growth conditions,the maintenance of landscape effects of H.heptaphyllum and A.japonica var.var iegata was better than that of G.jasminoides and S.japonica.H.heptaphyllum and A.japonica var.variegata were not sensitive to different concentrations of th ree pla nt growth inhibitors;the dwarfing rate of G.jasminoides with p aclobutraz ol was the highest(57.80%~59.21%),followed by S.japonica(38.00%~41.82%).Therefore,it was recommended to adopt extensive management for H.heptaphyllum and A.japonica var.variegata,and apply 300 mg·L^(-1) of p aclobutrazol to control the growth rate of G.jasminoides and〖WTBX.japonica,in order to stabilize the greening effect.
