Abstract
Description
[水耕栽培装置によって栽培される植物]
本実施の形態の水耕栽培装置100を用いて栽培される植物11の例として、オタネニンジン(高麗人参または朝鮮人参)等の根菜類が挙げられる。ただし、水耕栽培装置100によって栽培され得る植物は、これに限定されるものではない。
[本実施の形態における水耕栽培装置の構造]
図面を参照して、本実施の形態の水耕栽培装置100を説明する。
図1及び図2に示されるように、実施の形態の水耕栽培装置100は、筐体200内に設置されている。筐体200は、例えばコンテナや小屋のような内部空間を構成するものである。筐体200には、扉(図示せず)が設けられ、栽培者は、その扉を開閉することにより、筐体200に入ることができる。筐体200内の空間が水耕栽培装置100の地上空間Bを構成している。
からなるが、光源であれば、蛍光灯であってもよい。
[本実施の形態における水耕栽培装置の方法及び作用]
上述の構成により、本実施の形態では、以下のような方法及び作用で植物11に空気が供給され、植物11に対して最適な空気を送ることができる。
[効果など]
以上より、本実施の形態における水耕栽培装置100は、植物11を育成する育成槽1と、風を供給する送風部3と、送風部3から送られた風を植物11へと誘導する送風配管4と、を有している。送風配管4は、相互に略平行となる第一配管4aと、第二配管4bとを備えている。第一配管4a及び第二配管4bは、それぞれの管長手方向に複数の送風孔41が設けられ、送風孔41から植物11へ風を供給する。送風部3は、第一配管4a内の風の向きと第二配管4b内の風の向きとを略逆向きに風を供給する。
[変形例]
以上、本発明に係る水耕栽培装置100について、実施の形態に基づいて説明したが、本発明は、上記実施の形態に限定されるものではない。
1 育成槽
3、3a、3b 送風部
4 送風配管
4a 第一配管
4b 第二配管
5 送風制御部
