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(33)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 2B 2C 3,即氮磷钾比例1.3∶1∶1,氮肥浓度648.8 g/m3,微量元素浓度9.38 g/m3。

Abstract [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(33)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 2B 2C 3,meaning NPK proportion 1.3∶1∶1,nitrogen concentration 648.8 g/m3,microelement concentration 9.38 g/m3.

绿萝( Scindapsus aureus) 原产印度尼西亚所罗门群岛的热带雨林,生长于热带地区。绿萝属天南星科绿萝属大型室内攀藤观叶花卉,是重要的室内装饰植物之一,在国内及国际花卉市场占有重要地位。目前,绿萝主要采用温室大棚生产,施用通用型肥料,缺乏绿萝专用型肥料。在绿萝栽培管理过程中,施肥不足容易造成绿萝生长发育不良,延长生产周期,影响品质和产量;过度施肥容易引起绿萝灼伤、黄化、枯萎,同时造成肥料的浪费和环境的污染,从而对我国农业产业可持续发展产生不良影响。……
