Description

담액식 수경재배용 양액 시스템{Submerged Hydroponic Nutrient Solution System}Submerged Hydroponic Nutrient Solution System for hydroponics

본 발명은 담액식 수경재배용 양액 시스템에 관한 것으로, 보다 상세하게는 EC, pH 및 온도가 조절된 양액을 육묘상자에 지속적으로 공급가능하며, 사용한 양액을 회수한 후 재사용이 가능하도록 하여 양액의 낭비를 방지할 수 있으며 환경오염을 감소시킬 수 있는 담액식 수경재배용 양액 시스템에 관한 것이다.The present invention relates to a nutrient solution system for soaking-type hydroponics, and more particularly, it is possible to continuously supply a nutrient solution with EC, pH, and temperature to a seedling box, and it is possible to reuse the used nutrient solution after recovery, thereby waste of nutrient solution It relates to a nutrient solution system for immersion hydroponics that can prevent and reduce environmental pollution.

육묘는 논이나 밭에 이식할 것을 전제로 한 작물의 어린 식물인 모나 모종을 비교적 고밀도로 집약 육성시키는 것을 의미하는데, 작물의 어린 식물은 기상상태, 잡초 또는 각종 병충해와 같은 환경의 영향을 받기 쉬우므로 모나 모종을 논이나 밭에 직접 파종하는 대신 안전한 장소에서 일정기간 동안 육묘하여 재배하는 것이 생산적인 측면에서 유리하다. 최근 시설원예 면적증가로 모나 모종의 수요가 증가하고 있는 추세이며, 품질이 우수하고 균일한 모종을 선호함에 따라 모종 생산이 가능한 농가 개인이 육묘하던 방식에서 시설과 기술을 갖춘 전문화된 육묘장에서 이루어지는 공정육묘방식으로 점차 변화하고 있다.Seedling refers to the intensive nurturing of seedlings or seedlings, which are young plants of a crop, at a relatively high density, on the premise that they will be transplanted into rice fields or fields. Therefore, it is advantageous in terms of productivity to grow seedlings or seedlings in a safe place for a certain period of time instead of directly sowing them in paddy fields or fields. Recently, the demand for seedlings is increasing due to the increase in the area of facility horticulture, and as they prefer high quality and uniform seedlings. It is gradually changing to a breeding method.

이러한 모나 모종은 논이나 밭에 다른 작물이 재배되고 있을 때부터 육묘를 시작하여 그 작물의 수확 후에 육묘된 어린 작물을 곧바로 이식함으로써 토지를 유용하게 활용할 수 있다. 또한 보온이나 가온 방법에 의하여 일찍부터 육묘를 시작하여 논이나 밭에서 생육할 수 있는 기온이 되는 즉시 이식하게 되면 조기 수확 또한 가능하다는 장점이 있다.Such seedlings or seedlings can utilize the land usefully by starting seeding when other crops are being grown in paddy fields or fields, and transplanting the grown young crops immediately after the crop is harvested. In addition, there is an advantage that early harvest is also possible if seedlings are started early by warming or warming methods and transplanted as soon as the temperature is suitable for growth in paddy fields or fields.

육묘는 모종의 관리와 운반 뿐 아니라 이앙기를 이용한 모내기 작업의 편리성을 도모하기 위하여 대부분이 육묘상자를 모판으로 사용하고 있다. 이러한 육묘상자에 육묘하는 종래기술로는 '대한민국특허청 등록특허 제10-1224110호 딸기 육묘용 장치'와 같이, 저면 급수가 가능하도록 포트 하부에 급수구(62)가 형성된 자묘포트(61), 물을 수용할 수 있고, 수용된 물을 직접 냉각하기 위한 냉각 유체 순환관(20)을 구비하며, 상기 자묘포트(61)를 물이 직접 공급되도록 수용할 수 있는 하나 이상의 재배용기(30); 및 묘주포트(41)를 상기 재배용기(30)의 내부 또는 외부에 포함하는 기술이 알려져 있다.Most of the seedlings use a seedling box as a bed for seedling management and transportation, as well as for the convenience of planting using a rice transplanter. As a prior art for seeding seedling in such a seedling box, as in 'Korea Intellectual Property Office Registration Patent No. 10-1224110 Device for Growing Strawberry', a seedling pot 61 having a water supply port 62 formed at the bottom of the pot to enable bottom water supply, water At least one cultivation vessel 30 capable of accommodating, having a cooling fluid circulation pipe 20 for directly cooling the received water, and accommodating the seedling port 61 so that water is directly supplied; And the seedling port 41 is known technology including the inside or outside of the cultivation vessel (30).

이러한 종래기술을 포함한 일반적인 육묘기술은 밀폐되고 보호되는 내부환경에서 육묘를 재배하기 때문에 외부 이물질에 노출되지 않아 안전성을 확보할 수 있으며, 폭우, 폭설 등 자연재해가 발생해도 온도, 광량 습도 등의 재배환경을 인공적으로 만들어 외부 기상조건에 영향을 받지 않고 육묘를 안정적으로 생산할 수 있다. 이 뿐만 아니라 육묘 성장시 필요한 영양소인 양액을 이용해 육묘를 생산하고 있는데, 양액은 생육에 필요한 무기양분을 비율에 맞춰 물에 용해시킨 액에 해당한다. In general seedling techniques, including these prior art, because seedlings are grown in a closed and protected internal environment, safety can be secured because they are not exposed to external foreign substances. By creating an artificial environment, it is possible to stably produce seedlings without being affected by external weather conditions. In addition, seedlings are produced using nutrient solution, which is a nutrient required for seedling growth. Nutrient solution corresponds to a solution obtained by dissolving inorganic nutrients necessary for growth in water according to the ratio.

이러한 양액은 육묘에 맞춰 염류농도인 EC와 수소이온 농도인 pH 및 수온을 적절히 조절하여 공급하여야 한다. 하지만 양액의 경우 1ton 이상의 양액탱크에 저장된 상태로 육묘에 지속적으로 공급하기 때문에 양액의 EC, pH 및 수온을 매번 조절하기 어렵다는 문제점이 있다.These nutrient solutions should be supplied by appropriately adjusting the salt concentration EC, the hydrogen ion concentration, and pH and water temperature for the seedlings. However, there is a problem in that it is difficult to control the EC, pH and water temperature of the nutrient solution every time because it is continuously supplied to the seedlings in a state of being stored in a nutrient solution tank of 1 ton or more.

본 발명의 실시예에 따른 담액식 수경재배용 양액 시스템(10)은, 도 1 내지 도 6에 도시된 바와 같이 육묘상자(100), 상자지지부(200), 양액순환탱크(300), 양액공급펌프(400), 양액공급배관부(500), 양액배출배관부(600), 양액조절탱크(700), 양액회수배관부(800), 조절밸브(900) 및 제어부(1000)를 포함한다.As shown in FIGS. 1 to 6, the nutrient solution system 10 for soaking hydroponics according to an embodiment of the present invention is a seedling box 100, a box support unit 200, a nutrient solution circulation tank 300, and a nutrient solution supply pump. 400 , a nutrient solution supply pipe unit 500 , a nutrient solution discharge pipe unit 600 , a nutrient solution control tank 700 , a nutrient solution recovery pipe unit 800 , a control valve 900 , and a control unit 1000 .

육묘상자(100)는, 도 2 및 도 3에 도시된 바와 같이 내부에 양액을 저장하고 저장된 양액을 통해 육묘가 재배되는 상자로, 다양한 종류의 육묘가 양액을 통해 수경재배되도록 심어져 있다. 이러한 육묘상자(100)는 육묘의 대량 수경재배가 가능하도록 복수 개가 구비된다.As shown in FIGS. 2 and 3 , the seedling box 100 is a box in which a nutrient solution is stored therein and seedlings are grown through the stored nutrient solution, and various kinds of seedlings are planted so that they are grown hydroponically through the nutrient solution. A plurality of such seedling boxes 100 are provided to enable mass hydroponics of seedlings.

상자지지부(200)는, 도 4에 도시된 바와 같이 복수 개의 육묘상자(100)를 지지하는 선반 역할을 하는 구성으로, 일반적으로 육묘상자(100)를 4단 6열 또는 4단 8열로 지지하도록 구비된다. 즉, 육묘상자(100)는 상자지지부(200) 중 한 층에 길이방향을 따라 6개 또는 8개의 육묘상자(100)가 배치되고 6개 또는 8개의 육묘상자(100)가 4층으로 적층된 상태로 구비되며, 이러한 4단 6열 또는 4단 8열이 하나의 유니트로 이루어진 상자지지부(200)가 서로 간격을 두고 복수 개로 배치될 수 있다.The box support unit 200 is configured to serve as a shelf for supporting a plurality of seedling boxes 100 as shown in FIG. 4 , and generally supports the seedling box 100 in 4 columns, 6 columns, or 4 columns and 8 columns. provided That is, in the seedling box 100, 6 or 8 seedling boxes 100 are arranged on one layer of the box support unit 200 in the longitudinal direction, and 6 or 8 seedling boxes 100 are stacked in 4 layers. It is provided in a state, and a plurality of box support units 200 having 4 columns, 6 columns, or 4 columns and 8 columns as one unit may be arranged at a distance from each other.

경우에 따라서 상자지지부(200)에는 육묘상자(100)의 하부가 지지되는 영역에 LED 램프(미도시)를 더 포함할 수 있다. LED 램프는 백색광을 육묘에 비추어 빛이 들어오지 않는 환경에서도 육묘가 광합성을 할 수 있도록 구비된다. 또한 UV램프(미도시)도 추가적으로 구비될 수 있는데, UV 램프는 양액 내의 세균 또는 바이러스를 제거하여 육묘가 세균이나 바이러스에 의해 시들어 죽는 문제를 방지할 수 있다.In some cases, the box support unit 200 may further include an LED lamp (not shown) in the region where the lower portion of the seedling box 100 is supported. The LED lamp illuminates the seedling with white light so that the seedling can photosynthesize even in an environment where no light enters. In addition, a UV lamp (not shown) may be additionally provided, and the UV lamp removes bacteria or viruses in the nutrient solution to prevent the seedlings from withering and dying by bacteria or viruses.

양액순환탱크(300)는, 육묘상자(100)에 양액을 공급 및 회수하는 구성으로, 육묘를 키우기 위해 육묘상자(100) 내에 공급하기 위한 양액을 저장하는 탱크에 해당한다. 이러한 양액순환탱크(300)를 상세하게 설명하면, 육묘상자(100)에 공급하기 충분한 영양분을 가지는 양액을 양액순환탱크(300)에 저장해둔 상태에서 지속적으로 육묘상자(100)에 양액을 공급하고, 육묘 성장에 사용된 양액은 양액순환탱크(300)로 다시 회수된다. 이때 회수되는 양액은 육묘 성장에 영양분이 사용되어 남은 영양분이 충분하지 못하기 때문에 후술할 양액조절탱크(700)를 통해 양액의 EC, pH 및 온도를 조절한 후, 이를 다시 양액순환탱크(300)로 회수하게 된다.The nutrient solution circulation tank 300 is configured to supply and recover the nutrient solution to the seedling box 100 , and corresponds to a tank for storing the nutrient solution to be supplied into the seedling box 100 to grow seedlings. When describing the nutrient solution circulation tank 300 in detail, the nutrient solution having sufficient nutrients to be supplied to the seedling box 100 is stored in the nutrient solution circulation tank 300, and the nutrient solution is continuously supplied to the seedling box 100 and , the nutrient solution used for seedling growth is recovered back to the nutrient solution circulation tank 300 . At this time, the recovered nutrient solution is used for seedling growth and the remaining nutrients are not sufficient, so the EC, pH and temperature of the nutrient solution are adjusted through the nutrient solution control tank 700 to be described later, and then the nutrient solution circulation tank 300 will be recovered with

종래에는 양액이 재사용되지 않고 한번 사용된 양액은 버려지게 되었으며, 이 경우 양액에 사용되는 많은 양의 물을 재사용할 수 없어 물 낭비가 심할 뿐 아니라 영양분이 일부 포함된 양액이 그대로 강이나 바다에 배수되어 환경오염을 일으킬 수 있다는 문제점이 있었다. 특히 양액이 그대로 강이나 바다에 배수되면 강이나 바다에 존재하는 플랑크톤이 이를 섭취하여 녹조 또는 적조현상을 일으킬 수 있다는 문제점이 있었다. 이에 본 발명과 같이 양액순환탱크(300)를 이용하여 양액을 공급 및 회수하여 재사용할 경우 물과 영양분 낭비를 방지할 수 있어 환경에 유해한 문제를 해결할 수 있다.In the past, the nutrient solution was not reused and the nutrient solution used once was thrown away. There was a problem that it could cause environmental pollution. In particular, if the nutrient solution is drained into a river or sea as it is, plankton existing in the river or sea may consume it and cause green algae or red algae. Accordingly, when the nutrient solution is supplied, recovered, and reused using the nutrient solution circulation tank 300 as in the present invention, it is possible to prevent wastage of water and nutrients, thereby solving a problem harmful to the environment.
