PROBLEM TO BE SOLVED: To provide a hydroponics apparatus that uses hydrogen gas to accelerate the growth of plants in hydroponics and improve the quality thereof when plants are grown in hydroponics, while reducing the costs of cultivation.SOLUTION: The present invention provides a plant hydroponics apparatus provided with a device that stores a nutrient solution for plant hydroponics, a hydrogen gas supplying device for supplying hydrogen gas to the nutrient solution, and a blowing device for blowing the hydrogen gas into the nutrient solution. The method employs such a plant hydroponics apparatus to blow hydrogen gas into a nutrient solution during a period from the full development of true leaf to harvest after seeding of plant seeds when culturing plants in hydroponics in the device that stores a nutrient solution.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】水素ガスを用いて、植物を養液栽培するに際し、養液栽培における植物の生育促進や品質向上させるとともに、栽培コストを低減する養液栽培装置を提供する。【解決手段】少なくとも、植物を養液栽培するための養液を貯える装置と、この養液に水素ガスを供給する水素ガス供給装置と、この水素ガスを養液に吹き込むための吹き込み装置を備えた植物養液栽培装置を用いて養液を貯える装置内で植物を養液栽培するに際し、植物種子の播種後、本葉が本格的に展開する時期から収穫までの間に当該水素ガスを養液に吹きこむ植物の養液栽培方法。【選択図】図2
