摘要 [目的]为绿篱植物大叶黄杨探索节约型的化学修剪新途径。[方法]研究不同浓度多效唑对大叶黄杨的矮化效果和经济效益的影响。[结果]单一大叶黄杨绿篱以浓度为6 667 mg/kg多效唑、用药量500 ml/m2、喷施3次的处理最佳;使用该技术全年节约成本约4.6元/m2。[结论]绿篱植物大叶黄杨喷施一定剂量多效唑可以代替人工修剪,经济效益和景观效益显著。 [ Objective] The research aimed to find out an economical way of chemical priming for a hedge plant, Euonyraus japonicus. [ Method] ]The effects of different concentrations of paclobutrazol on the dwarfing effect and the economic benefit of E. japon/cus were studied. [ Result ] The optimum com- bination was as follows:6 667 mg/kg paclobutrazol, drugs dose of 500 ml/m^2 and the spraying frequency of 3 times. The cost could be saved by 4.6 yuan/m^2 annually by using that technique. [ Conclusion ] Artificial pruning could be replaced by spaying certain concentration of paclobutrazo on E. japonicus. And it had remarkable economic and landscape benefits.
