Title: 수경재배용식물의생장용기및재배방법
Filed: 1999-04-02
Abstract: 본 발명은 가정에서 애용하는 콩나물과 같은 애용식물을 손쉽게 기를수 있도록 하기위한 발명인 동시에 대량생산을 하여 제조원가를 줄이기 위한 발명인 것이다. 
     종래의 콩나물은 시루와 같은 용기에 콩을 담아 용기의 상부에서 물을 살포 하여주다보니 수분을 흡수하는 뿌리부분까지 수분이 도달하는 시간이 오래 걸리기 때문에 뿌리 썩음 병과 같은 질병이 발생하다보니 병충해를 예방하기 위하여 농약과 같은 약제를 식물에 살포하는 사례가 종종 발생되곤 하였던 것이다. 
     이러한 결점을 해결하고자 하는 본 발명의 구조는 다음과 같다. 
     피이티병의 재질과 같은 완전 밀폐된 용기에 있어서 용기의 상부에는 소수의 숨구멍을 구성시켜 주고 용기의 하부옆면에는 다수개의 흡배수 구멍을 구성시켜주어 식물이 필요로 하는 수분을 손쉽게 공급 시켜줄수 있도록된 구조이며 다수개의 통공구를 구성시켜준 형상이다. 
     수분의 공급 방법은 용기의 하단부옆에 형성되는 하부배수 구멍으로 하여주는 것이 식물의 생장에도 유익한 것이다. 
     식물의 재배상자에 재배용기를 다수개 투입시킨다음 식물재배상자의 상단에 구성된 유동자를 주기적으로 유동시켜주어 물탱크속의 물이 재배용기에 침투될수 있도록 구성시킨 구조이다, 유동자의 조절은 감속기를 이용한 주기적인 유동을 조절하여 주면 되는 것이다. 
     이러한 용기를 이용하여 식물을 생장시켜주게 되면 다음과같은 효과가 있는 것이다. 
     콩나물과 같은 식물의 생장 한계점을 용기의 크기에 의하여 억제 시켜주기 때문에 식료품점에서 항상 물속에 담아놓고 싱싱한 콩나물과 같은 식물을 판매할수가 있는 것이다. 
     또한 재배하는데 필요한 인력이 절감되기 때문에 재배 용기의 비용을 상쇄 하고도 남을 것이다. 
     밀폐된 용기에 구성된 상,하부의 숨구멍을 통하여 다수개의 식물 씨앗을 투입한다음 감속기에 의하여 유동하는 유동자의 재배방법을 이용하여 재배하여주면 간단히 식물의 재배가 완료되는 것이며 용기속의 식물을 시장판매 하는 시점은 재배자의 자율 사항이지만 용기속의 식물이 밀폐용기의 상부에 다다르기 전에 시장출하 하여주게 되면 유통과중에 웃자라는 공간을 확보하여줄수가 있는 것이다. 
     이러게 하여주는 이유는 콩나물과 같은 식물을 유통하여 주다보면 유통과정중에 웃자란 콩나물과 같은 것을 속아내어 재차 상품화하다보니 오히려 판매 상인들이 불편해 하였던 것이다.
