| 육묘장의 두상관수장치는 균일하게 관수되어야 모종도 균일하게 성장한다. 본 연구에서는 부채꼴 분사노즐을 이용한 두상관수장치의 노즐 설치위치에 따른 관수상태를 조사하여 균일관수방법을 구명하였다. 살수량은 주행속도에 반비례하였고, 관수균일도는 노즐과 관수면과의 거리에 큰 영향을 받으며 주행속도의 영향은 없었다. 단일노즐에 의한 두상관수인 경우 노즐 끝에서 관수면이 60cm 이상 멀어질수록 관수균일도가 향상되며, 연속노즐에 의한 두상관수인 경우 관수면이 노즐분사 각도의 2차 교차점에 위치할 때 관수균일도가 가장 좋은 것으로 나타났다. 두상관수장치의 균일관수를 위해서는 작물의 머리높이가 분사노즐의 2차교차점에 일치하도록 노즐의 위치를 정해야 하며 작물의 자람에 따른 노즐대 놀이를 조절해 주는 것이 바람직한 것으로 판단된다. |

| The one of basic functional conditions of suspended overhead sprayer, which is openly made use of irrigating on bedding plants in greenhouse, is to be kept the growing uniformity of bedding plants by making uniformly the spraying irrigation depending on the distribution of sprayed water. This study was performed to find out the optimum position of sector formed injection nozzle which is placed from the top of plant 0 the tip of the nozzle to keep spraying uniformity. The test of spraying distribution using a overhead sprayer, which was installed in a row of sector formed injection nozzles, was performed The measuring factor to represent spraying distribution was the water weight filled in each cup when the overhead sprayer was moving across the upside of the cups which were placed directly under the nozzles on keeping the distance from nozzle tip. The test results were as following , The standard mr of weights of each cup filled with spraying water was lower values at Position far from more than 60cm under nozzle tip. The driving speed variation of sprayer was not effected on spraying uniformity but the spraying water weight was inversely proportioned to the speed. To make best spraying uniformity, it was represented that the tip of the nozzle is positioned to keep the distance which the top of plants is placed at the second cross point of each injection sector of nozzles |
