PROBLEM TO BE SOLVED: To provide a plant cultivation method that can increase the iron content of leaf vegetable.SOLUTION: A plant cultivation method is a method for cultivating leaf vegetable while supplying nutritious liquid. Assuming that a period from dissemination until the day before a-th day is a first period, a period after a-th day until the day before b-th day is a second period, a period after b-th day until a harvest day is a third period, in the second period, nutritious liquid having pH3.5 or more and 4.9 or less to which iron is added by 0.5 ppm or more and 10.0 ppm or less is supplied as nutritious liquid, and in the third period, nutritious liquid having pH3.5 or more and 4.9 or less to which iron is added by 5.0 ppm or more and 100.0 ppm or less is supplied.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2019,JPO&INPIT【課題】葉菜類の鉄含有量を高めることができる植物栽培方法を提供する。【解決手段】養液を供給して葉菜類を栽培する方法であって、播種からａ日目の前日までを第１期、ａ日目以降ｂ日目の前日までを第２期、ｂ日目以降収穫日までを第３期として、第２期では、養液として鉄を０．５ｐｐｍ以上１０．０ｐｐｍ以下添加したｐＨ３．５以上４．９以下の養液を供給し、第３期では、養液として鉄を５．０ｐｐｍ以上１００．０ｐｐｍ以下添加したｐＨ３．５以上４．９以下の養液を供給する植物栽培方法。【選択図】図３
