Stereoscopic layered device for fast breeding of virus-free seedlings of potatoes

The invention discloses a stereoscopic layered device for fast breeding of virus-free seedlings of potatoes. The device comprises a culture tank, a filter net, a liquid returning space and a nutritiontank; the culture tank comprises a first culture tank body, a second culture tank body, a third culture tank body and a fourth culture tank body; the filter net comprises a first filter net body, a second filter net body, a third filter net body and a fourth filter net body; the liquid returning space comprises a first liquid returning space body, a second liquid returning space body, a third liquid returning space body and a fourth liquid returning space body. The device solves the problems that a traditional production mode of of the virus-free seedlings of the potatoes not only wastes massive manpower and material resources but also causes serious threats to environmental protection and soil and water conservation, and there is the uncertainty that harvesting of the potatoes depends onweather. 本发明公开了一种立体分层快繁马铃
