摘　　要：为研究植物根系分离与植物根系不分离2种方式水培植物组合净化室内甲醛效果,确定能够最大限度地发挥水培植物组合净化甲醛的科学栽培方式,并为设计和制造水培植物组合栽培容器与设备提供有效指导,该文以6种常见水培植物:尖尾芋(Spathiphyllum floribundum)、鹅掌柴(Schefflera octophylla)、鸟巢蕨(Neottopteris nidus)、绿萝(Epipremnum aureum)、绿精灵合果芋(Syngonium podophyllum‘Pixie’)、狼尾蕨(Davallia bullata)为试验材料,采取真实房间污染模拟,根据试验房间甲醛浓度变化与植物逆境生理指标分析植物甲醛吸收能力与耐受能力的差异。研究发现,水培植物组合吸收甲醛能力排序为植物根系分离实验组>植物根系不分离实验组>水对照组。隶属函数分析法表明,植物根系分离水培植物组合方式能够增强植物甲醛耐受能力。植物根系分离的水培植物栽培组合方式能够更好地发挥水培植物净化甲醛效果。The effect of two combinations of hydroponic plant root separation group and root non-separation group on the indoor formaldehyde purification was studied,to determine the scientific cultivation method that can maximize the purification of formaldehyde by hydroponic plant combination,which would provide effective guidance for design and manufacture of combined hydroponic containers and equipment.Common hydroponic plant species including Spathiphyllum floribundum,Schefflera octophylla,Neottopteris nidus,Epipremnum aureum,Syngonium podophyllum‘Pixie’,Davallia bullata were selected as experimental material.Based on the changes in concentration of tested room and physiological indexes of plants under stress,the simulation of real room pollution was used to analyze the differences in hydroponic plants’formaldehyde absorption and tolerance of formaldehyde.Results indicated that the ability of hydroponic plant combinations to absorb formaldehyde was ranked as plant root separation experiment group>plant root non-separation experiment group>water control group.The membership function analysis showed that the combination of root non-separation could enhance formaldehyde tolerance of hydroponic plants.The hydroponic plant’s combination method with plant root separation can better purify formaldehyde.
