  • An Aero-NFT nutriculture system using microcomputer for cultivation of greenhouse melon was developed and the performance of the system was evaluated through experiments. The system could control temperature, EC and pH of the nutrient solution within the error ranges of $\pm$ 0.2$^{\circ}C$, $\pm$ 0.2 mS/cm, $\pm$ 0.1 pH, respectively. The results of cultivation experiment showed that temperature, EC and pH of the nutrient solution were generally controlled within the setting ranges during cultivation period. The growth results were good until pinching, but the fruit quality of melons was not high except sweetness and shape. To optimize performance of the system, more techlical information for nutriculture of greenhouse melon was needed.

  • Hydroponics, Nutriculture, Soilless culture 라고 불리워지는 양액재배는 결코 새로운 기술은 아니지만 최근 집약적 생산을 위한 공장적 재배 등을 통해서 다시 주목을 받고 있다. 과거에는 재배관리의 어려움 때문에 전문가 이외에는 재배가 곤란했지만, 최근 재배관리의 자동화경향 때문에 비전문가에 의한 관리도 가능하게 되고 있다. 양액재배는 토양재배에 비하여 여러가지 장점을 가지고 있다. 양액관리를 위한 장치의 개선과 적용작물의 선택, 생력관리기술이 확정되었고, 연작장애 대책, 안정적 계획생산, 무공해식품의 평가가 높기 때문에 양액재배 면적은 서서히 증가하는 추세라 할 수 있겠다.

  • 현재 우리나라의 양액재배 농가에서의 양액관리는 대부분은 계측에 의하여 양액의 농도를 조절해 주지 못하고 있으며, 대부분이 일정비율 내지 일정간격으로 양액을 보충해 주거나 몇 일 간격으로 양액 전체를 교환해 주고 있는 실정이며, 자동화 장치를 가지고 양액재배를 하는 농가는 거의 없는 실정에 있다. 따라서 양액관리의 정확성 및 성력화가 이루어지고 있지 못하며 이에 따른 생산성 향상 및 고품질을 기대하기란 실로 어려운 상황에 있다. (중략)

  • This experiment was conducted to investigate the effects of concentrated pig slurry using membrane filter on growth of tomato in nutriculture. Pig slurry was filtered by ultra filtration and concentrated by reverse osmosis process. Filtration of pig slurry was necessary to prevent the hose clogging in nutriculture. The concentrated pig slurry (CS) and nutrient solution (NS) were mixed by six different mixing ratios of 0:100, 20:80, 40:60, 60:40%, 80: 20 and 100%:0% based on nitrogen content. The chemical nutrient solution was the solution of National Horticulture Research Station for the growth of tomato. The concentration of nutrient solution was adjusted a range of $1.6{\sim}2.0mS/cm$ in EC. The plant height of tomato treated with CS 20+NS 80% was similar with NS 100% control plot. Plant height was highest in the plot of CS 20+NS 80%. The treatment of 100% concentrated pig slurry was lowest in the gowth characteristics of tomato. Number of cluster was very lower in 100% concentrated pig slurry compared with plot of chemical nutrient solution. In the beginning of growth stage, SPAD reading value was reduced in plot treated with CS 100%, but CS 20+NS 80% plot was higher compared to 100% concentrated pig slurry. SPAD value of tomato leaves was decreased as the amount of CS was increased. The SPAD value also in treatment of concentrated pig slurry was lower in the middle growth stage compared to control plot. The dry weight of stem and leaf were 107.4, 104.2g in plot of NS 100% and CS 20%+NS 80%, respectively. The fruit number and weight were decreased at high application plots of concentrated pig slurry, The fruit setting of tomato showed lowest in the plot treated with 100% concentrated pig slurry, and the growth of tomato severely decreased after application of 100% CS treatment. In conclusion, the growth characteristics such as plant height and fruit weight of tomato were not significantly different between the plots treated with mixture of 20% CS +80%NS and 100% nutrient solution treatment. In conclusion, the mixture solution of 20% of concentrated pig slurry and 80% of nutrient solution could be used as a nutrition solution of tomato nuticulture.
