Abstract

Melons are mostly grown in soil, but it is susceptible to damage due to injury by continuous cropping such as Fusarium wilt and root rot. Hydroponic cultivation system can overcome the disadvantages of soil cultivation with precise nutrition management and a clean environment. When using the coir substrate, the most environmentally friendly organic substrate used for hydroponics, it is analyzed how the growth and fruit quality of the melon depends on the ratio of chips and dust and the amount of irrigation. The purpose of this study was to provide the basic data of melon hydroponics when cultivated in spring. The two types of the coir substrates used in the experiments were chip and dust ratios of 3 :7 and 5 : 5 respectively. The substrate with high dust ratios had excellent physical characteristics, such as container capacity and total porosity, and the drainage EC level showed a high value of $3.0-6.8dS{\cdot}m^{-1}$. When the amount of irrigation is provided based on the drainage rate, the group provided the nutrient solution on the basis of 10% drainage supplied 91 L per plant, which was reduced by about 30% compared to the group with the highest water supply. In addition, the total drainage showed less than 10 L per plant with a minimum water supply and was reduced by 30 - 70% in substrate with a high dust rates. In substrate with high water supply and high dust ratio, leaf growth and fruit enlargement were good, and the soluble solids content varies greatly from cultivar to cultivar. If you provided the amount of irrigation based on 10% drainage rate, the fruit weight will be decreased, but the amount of irrigation can be reduced. Therefore, it is considered that managing the water & nutrient properly taking into account the characteristics of coir substrate and cultivar can produce melon of uniform quality using hydroponics.

최근 수경재배에서 가장 많이 사용되는 친환경 유기배지인 코이어 배지를 사용하였을 때 코이어 칩과 더스트 비율, 급액량에 따라 멜론의 생육과 과실 품질을 분석하고 봄 재배시 코이어 배지를 이용한 멜론 수경재배의 기초 자료를 제공하고자 본 연구를 수행하였다. 실험에 사용한 2 종류의 코이어 배지는 칩과 더스트의 비율이 각각 3:7, 5:5이었으며, 배액률 10, 20, 30% 수준으로 급액하였을 때 멜론의 생육과 품질 변화, 배지의 물리적 화학적 변화를 분석하였다. 배액률 10%를 기준으로 양액을 공급한 처리구는 총 급액량이 주당 91L로 급액량이 가장 많은 배액률 30% 처리구에 비해 약 30% 절감되었다. 총 배액량 또한 급액량이 가장 적은 배액률 10% 처리구에서 주당 10L 이하로 낮은 값을 나타내었다. 더스트 비율이 높은 칩:더스트 3:7 배지는 5:5 배지보다 총 배액량이 약 30-70% 감소하였다. 급액량이 많고 더스트 비율이 높은 3:7 배지를 사용했을 경우 엽생육과 과실 비대가 좋았고 당도는 품종 간 차이가 컸다. 배액률 30%를 기준으로 급액하면 배액률 10% 기준으로 급액하였을 때보다 과중이 21% 증가하였다. 더스트의 비율이 높은 3:7 배지는 5:5 배지보다 용기용수량, 공극률 등 배지 물리성이 우수하였고, 재배 기간 중 네트발현기 이후 배액 EC가 $3.0-6.8dS{\cdot}m^{-1}$로 높은 값을 나타내었다. 재배 품종 특성 및 재배 조건 등을 고려하여 적정한 양수분 관리를 하면 코이어 배지를 이용한 수경재배 시 고품질의 멜론을 생산할 수 있을 것으로 판단된다.
