According to the research of the cultivation result on the spot farmers for 5 years in order to investigate its cultivation conditions and problems of Lycium chinetrse Mill, the development of the variety with early mature, pest tolerance, and high yielding is urgent and it is call for the development of rooted cutting cultivation by testing of bed soil, growth regulator and cutting times. The development of cultivation method with planting year, planting density, supplementary period and amounts of supplementary of Lycium chinense Mill planted in growing field are required and for the disease and the effective control of disease and insect pest resistance is needed by auxotrophic fertilizing and organic agricultural method, met by agricultural chemicals.

본 연구에서는 표고톱밥 지면재배에서 참나무 톱밥 조직의 분해와 배지의 갈변 특성을 내외부 형태적으로 조사하였다. 표고균 접종 50일후에는 갈변이 시작되었다. 접종 110일 후 표고균사는 참나무 톱밥 목부조직내 도관, 목섬유, 유세포의 내외부에서 세포벽을 분해하고, 톱밥 표면에 밀집한 균사는 세포외벽을 부정형으로 분해하였다. 그동안에 흰색인 배지 표면 균사는 대부분 깨끗한 갈색으로 변하였고, 이 갈변층 두께는 약 0.34 mm로 표고균사가 치밀하였고, 그 아래에는 흰색의 활력있는 균사층이 있었다. 반면에 검정색 층은 두께가 약 1.17 mm로 미끈거리는 표면에는 세균과 잡균 균사 및 포자들이 점유하고, 그 아래에는 활력이 쇠퇴한 균사층이 존재하였다. 갈변표면의 경도는 약 $0.73kgf/cm^2$로 검정색 표면의 경도 약 $0.91kgf/cm^2$보다 물렀으나 탄력이 있었다. 표고 자실체는 표고균사 접종 150일 후에 밝은 갈색의 배지 표면에서는 발생하였으나, 검정색 표면층에서는 발생하지 않았다.

Even though the development of livestock industry in Asia and Australasia has brought the economic growth and thus elevated the living standard in these areas, it has also brought the pollution caused by the increasing amount of animal wastes. Among them, Japan probably is the first country that suffered from the animal waste pollution as early as in 1970s. Nowadays, the animal waste pollution has been a common problem for almost every countries in this region. To solve it, different measures and regulations have been implemented in many countries. In this paper, different methods for animal waste disposal are discussed, including: manure-bed animal housing, composting, anaerobic treatment, odor control, utilization of biogas, aerobic treatment, three-step process, N and P removal, land application, cultivation of algae, anaerobic treatment of dead animals. It is hoped that an animal industry without pollution can be achieved in the future.

This study was carried out to file up structural design data for optimizing Pleurotus eryngii growing houses. Design data are including current farm status of Pleurotus eryngii growing houses in the aspect of structural configuration as well as environmental conditions to be controlled and maintained inside. A structural analysis was performed for the on-farm structures as well as some structures modified and suggested through field survey and analysis. The results are summarized as follows. According to the results of status analysis, Pleurotus eryngii growing houses were categorized as arch-roofed simple type and sandwich panel type. Though the size of Pleurotus eryngii cultivation facilities were considerably diverse, the basic dimensions of Pleurotus eryngii cultivation facilities showed relatively similar pattern: more or less of 20m of length, $6.6\~7.0m$ of width, $4.6\~5.0m$ of peak height, $1.2\~1.6m$ of bed width, and 4 layers of bed. In the aspect of spatial use of cultivation facilities, suggested models were shown to be mostly reasonable in the aspect of heating and cooling, micro-meteorological stability, land use efficiency per unit floor area, etc.. Especially, the standard models suggested so far were thought to be not efficient in its surface area and spatial volume per unit floor area as well as its uneffective structural design in the area around ceiling. In the results of structural analysis for the models suggested through this study by using those section frames to be found on farms, the panel type structures of both single span and double span were estimated to be over designed, whereas arch-roofed pipe houses were mostly found to be under-designed.

Perforated vinyl mulching technique was performed on Pleurotus sajor-caju beds to assess fruitbody formation. Individual fruitbody of P. sajor-caju was transformed into bunch type on vinyl mulching bed. It was effective to grow the mushroom without waterlogging and abortion of small pins on the beds as well as hygienical bed management. A bunch showed 79 fruitbodies and 225 g of weight. Available site for fruiting was reduced up to 20% in comparison of 100% for conventional bed. The color of fruitbody turned on brownish white from treated vinyl mulching bed.

This experiment was conducted to investigate the effects of turf grass growth to seedling rates and bed soil types. The results of this experiment were summarized as follows; the more increasing the seedling rates, the plant height and leaf length were longer, but the number of leaf and number of branch were fewer. Incase of transplanting of turf grass seedling by rice transplanting machine, it might be considered that the proper alternative bed soil was sandy loam soil with regarding to the economic aspects. The maximum seedling rate of turf grass in the seedling tray for rice was 1,000 of seedling amount due to the nutrient competition with intensive seedling. As the results indicated, it might be recommended that the proper alternative bed soil was sandy loam soil with 1,000 of seedling rates in case of transplanting of turf grass seedling by rice transplanting machine.

This study aimed to investigate the effects of an aquaponics system utilizing catfish recirculating water on the growth and water quality in lettuce and chicory cultivation. After 60 d of catfish cultivation in the BFT-AP, the survival rate was 96.0% and average weight gain was 178.5 g. The WGR grew by 241.4% and the SGR was 3.0%. A comparison between lettuce and chicory cultivation using BFT-AP and hydroponics revealed significant increases in shoot height, leaf count per week, and biomass of the cultivated lettuce and chicory. The SPAD values also increased significantly by 15.4-43.3%. Water quality analysis of the BFT-AP systems and crop cultivation beds showed significant differences, except for K and Na. The average NO₃^- concentration in the sediment pond was significantly higher at 45.3±1.0. Comparison of water temperature, pH, EC, DO, and ORP in the BFT-AP system and crop cultivation beds revealed similar monthly water temperatures from July to September. The pH in the catfish culture pond was 0.3-1.2 lower than that in the crop cultivation beds, and the EC was approximately 0.01- 0.03 dS/m lower in the catfish culture pond than the crop cultivation beds. The monthly average ORP in the catfish culture bed steadily increased to 479.9 mV in October. Bacillus velezensis (AFB2-2) and Chlorella fusca (CF) were applied to the biological activation bed; the population density of CF showed a continuous increase, whereas that of AFB2-2 decreased after 15 d and gradually increased thereafter. Thus, the application of the recirculating aquaponics cultivation technology with catfish (BFT) enhances catfish cultivation and promotes the growth of lettuce and chicory. Therefore, it is considered suitable for the environment-friendly cultivation of lettuce and chicory.
