摘　　要：[目的]研究氮磷钾比例、氮肥浓度和微量元素浓度对温室盆栽绿萝生长的影响,以期为绿萝的施肥管理提供参考。[方法]以青叶绿萝为试验材料,以氮磷钾比例、氮肥浓度和微量元素浓度为试验因子,采用L_(9)(3^(3))正交设计的方法对温室盆栽绿萝生长的影响进行研究。[结果]氮磷钾比例对温室盆栽绿萝总根长、叶面积的影响差异极显著,对茎长的影响差异显著。氮肥浓度对根系表面积、SPAD值的影响差异显著。[结论]氮磷钾比例、氮肥浓度和微量元素浓度最有利于温室盆栽绿萝生长的最佳组合是A_(2)B_(2)C_(3),即氮磷钾比例1.3∶1∶1,氮肥浓度648.8 g/m^(3),微量元素浓度9.38 g/m^(3)。[Objective]Effect of NPK proportion,nitrogen concentration and microelement concentration on growth of Scindapsus aureus was studied to provide reference for fertilization management with Scindapsus aureus potted in greenhouse.[Method]Orthogonal design with 3 factors L_(9)(3^(3))was operated to investigate the interaction of NPK proportion,nitrogen concentration and microelement concentration on growth of Scindapsus aureus named“green leaf”.[Result]NPK proportion promoted the total root length and leaf area of Scindapsus aureus extremely significantly,promoted the stem length significantly.Nitrogen concentration promoted root surface area and SPAD value significantly.[Conclusion]The best formula fertilizer combination of Scindapsus aureus was A_(2)B_(2)C_(3),meaning NPK proportion 1.3∶1∶1,nitrogen concentration 648.8 g/m^(3),microelement concentration 9.38 g/m^(3).
