Abstract

Melons, a rich source of vitamins and fibers, are commonly grown in the soil. Hydroponic cultivation could improve yield and quality of melon and selection of substrate volume and the kind of substrates is important for hydroponic cultivation of melons. This study investigated the effect on melon growth according to volume of granular rockwool and substrates of coir and rockwool slab. 'Geumsegye' melon (Cucumis melo L. cv. Geumsegye) was cultivated hydroponically according to volume of granular rockwool to 1.0, 1.5, 2.0, 3.0, and 4.0 L, and was also cultivated using coir and rockwool slabs. Logistic model was applied to estimate the growth characteristics of melons such as plant height, leaf length, leaf width, and the characteristics of fruit. The growth characteristics of melons were significantly increased at 4.0 L compared to those grown of 1.0 L volume of on granular rockwool, and the results were the highest in coir and rockwool slabs. Melons grown in rockwool slabs showed the largest fruit fresh weight, fruit length, and fruit width. During hydroponic cultivation, growth characteristics of melon appropriate at the 4.0 L volume of granular rockwool, and the highest at coir and rockwool slabs. This study provides a basis for understanding the effect of root zone environment to the growth characteristics and fruit quality of non-netted melon.

멜론은 풍부한 비타민과 섬유질을 제공하는 작물로 대부분 토양에서 재배하고 있다. 그러나 수경재배를 통해 생산량과 품질을 높이기 위한 시도가 늘어나고 있는 추세에 있으며, 생육을 최대화할 수 있는 배지에 대한 요구도가 높은 작물이다. 본 연구에서는 입상 암면 배지를 이용하여 근권부 용량을 다르게 수경재배한 경우와 코이어 및 암면 슬라브 배지를 활용하여 수경재배한 경우 멜론의 수체와 과실의 생육에 어떠한 영향이 있는지 파악하고자 하였다. '금세계' 품종(Cucumis melo L. cv. Geumsegye)을 입상 암면 용량을 1.0, 1.5, 2.0, 3.0, 4.0L로 달리하여 수경재배하였으며, 코이어 슬라브와 암면 슬라브를 사용해 재배하였다. 작물의 초장, 엽장, 엽폭 등 생육 특성을 조사하여 로지스틱 모델을 적용하였으며, 과실의 특성을 분석하였다. 멜론의 생육 특성은 1.0L 용량의 입상 암면에서 재배한 것에 비해 4.0L 용량에서 유의하게 증가하였고, 코이어 슬라브와 암면 슬라브에서 가장 높은 결과를 나타내었다. 암면 슬라브에서 재배한 멜론에서 가장 과실 생체중과 과장, 과폭이 크게 나타났다. 수경재배 시 입상 암면 용량은 4.0L 수준에서 가장 생육이 좋으며, 코이어 슬라브와 암면 슬라브 등을 이용하는 것이 가장 좋은 생육을 보였다. 앞으로 무네트 멜론의 근권부 환경에 따른 생육을 확인하는 연구가 추가적으로 수행될 필요가 있다.
