The present invention provides a method of cultivating shiitake mushrooms by using extruded germanium water and using a germanium water production device (40) comprising: a production device (10) which includes a germanium extruded water (G) production means (11) in which regular water (1) introduced from an upper part thereof, while flowing below a germanium stone laminated plate (12) and a germanium filter (13), is slowly pressurized in a vortex to have a germanium component sufficiently permeated in the regular water (1)； a mixing and stirring unit (20) which is communicated with downstream of the production device (10) to receive the primarily produced germanium extruded water (G) and at the same time, to enhance chemical molecular bonding of the regular water (1) and the germanium component through a uniform rotation； and a water collection unit (30) which is communicated with downstream of the mixing and stirring unit (20) to store the secondarily produced germanium extruded water (G), wherein the shiitake mushrooms are cultivated as the germanium extruded water (G) is regularly sprayed on shiitake mushroom seeds (51) cultured in a culture medium (50) by communicating with a water collection unit (30) of the germanium water production device (40). By spraying the germanium water produced through the germanium water production device evenly on the shiitake mushrooms cultured in the culture medium, the present invention improves the productivity of shiitake mushrooms and enables the cultivation of shiitake mushrooms of good quality. Further, the cultivated shiitake mushrooms which are rich in the germanium component provide health benefits including improvement of blood circulation, prevention of aging, prevention of adult diseases, and improvement of immunity in a human body.본 발명은 게르마늄 압출수를 이용한 표고버섯의 재배방법에 있어서； 상부로부터 유입된 일반수(1)가 게르마늄석 적층판(12) 및 게르마늄필터(13) 아래로 흐르는 과정에서 와류형태로 서서히 가압시켜 게르마늄 성분이 일반수(1)에 충분히 함유되도록 게르마늄 압출수(G)의 생성 함유수단(11)을 갖는 생성장치(10)와； 상기 생성장치(10)의
