PROBLEM TO BE SOLVED: To provide a method capable of watering plants by a watering amount preferable for the growth of plants, as a cultivation method of plants using solid culture medium.SOLUTION: A cultivation method of plants using solid culture medium which restricts a root zone includes: (a) a process of setting a watering amount per solar radiation amount (b) a process of setting an upper limit value and a lower limit value of soil moisture content of the solid culture medium (c) a process of measuring soil moisture content of the culture medium, comparing the soil moisture content with the set upper limit value and lower limit value, and adjusting the watering amount and (d) a process of giving water of a watering amount per solar radiation amount which is adjusted by the process (c) to the solid culture medium when solar radiation reaches a preset solar radiation amount.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】固形培地を用いる植物の栽培方法として、植物の生育に好適な潅水量により潅水を行うことができる方法を提供する。【解決手段】根域を制限する固形培地を用いる植物の栽培方法であって、(a)日射量当りの潅水量を設定する工程、(b)前記固形培地の土壌水分量の上限値及び下限値を設定する工程、(c)培地の土壌水分量を測定し、該土壌水分量と前記設定された上限値及び下限値とを比較し、前記潅水量を調節する工程、ならびに(d)予め設定された日射量に日射が達したときに、工程(c)により調節された日射量当りの潅水量の水を前記固形培地に与える工程、を含む前記栽培方法。【選択図】図1
