원예용 육모 상토로서의 지렁이 분립의 이용에 관한 연구
한정아(Junga Han),전하준(hajoon Jun),조익환(Ikhwan Jo) 유기성자원학회 1994 유기물자원화 Vol.2 No.1
본 연구는 지렁이 분립의 혼합비율이 고추 플러그묘의 생육에 미치는 효과를 조사하기 위하여 수행되었다. 본 연구에서는 지렁이의 분립은 20, 30, 40, 50%로 투입하고 나머지는 peatmoss 와 vermiculite로 보충하여 배합하였다. 얻어진 결과는 다음과 같다. 1. 엽수, 엽면적, 건물수량등에서 차이가 있었으며 (0.1%의 통계적 유리성) , 지렁이 분립의 혼합비율에 있어서는 엽수, 엽면적 및 경중에서 1%와 엽중, 근중 및 생물학적 건물수량에서 5%의 유의성이 인정되었다. 2. 지렁이 분립을 혼합한 상토가 국내 시판중인 상토 보다 조사후기에 접어들수록 많은 엽수와 엽면적의 증거를나타내었다. 3. 지렁이 분립을 처리한 상토에서 대조구보다 전 육묘기간을 통해 엽중, 경중 및 근중 등이 전반적으로 높았는데, 이러한 경향은 지렁이 분립의 비율이 40% 이상에서 현저하였다. 4. 조사시작 후 3주째까지는 엽중이 경중보다 높았지만 4주째 부터는 경중이 더 높았으며,또한 육묘후기에는 지렁이 분립을 혼합한 처리에서 대조구 보다 경중이 더 높았다. 5. 생물학적 건물수량은 조사초기에는 처리간 차이가 없었으나 후기에는 지렁이 분립을 혼합한 처리구가 대조구보다높았다. Earthworm cast was investigated in this study in order to domestically develop inexpensive and safe plug nursery soil. 20,30,40 and 50% of earthworm cast were added to the nursery soil as vegetable plant growth media, in which peatmoss and vermiculite constituted the rest of the soil. The effects of earthworm cast on the growth of pepper (Capsicum annuum L.) seedling were obtained as fo l1ows. 1. According to the growth stages, significant differences(p=O.OO 1) were recorded in number of leaves, leaf area and biological dry matter yield per plant(shoor or root dry matter yield per plant). In view of mixing ratios in the nursery soil, number of leaves, leaf area and stem weight per plant showed differences significantly at 1 % level and leaf weight, root weight and biological dry weight per plant at 5% level, respectively. 2. The nursery soil with earthworm cast showed increased number of leaves and leaf area per plant compared to the commercial nursery soil particularly in the later stage of this study than in the earlier stage 3. Through the total period of seedling growth, leaf weight, stem weight and root weight per plant in the nursery soil with earthworm cast were genral\y higher than those in the control and this trend was apparant in the treatment of more than 40% of mixing ratio with earthworm cast. 4. Although leaf weight per plant was higher than stem weight per plant till the 3rd week, from the 4th week stem weight per plant was getting higher. In the later stage of seedling growth, the stem weight was higher in the earthworm cast mixed treatment than that in the control. 5. There was no significant difference on biological dry matter yield in the earlier stage of this study, however in the later stage, it was higher in the earthworm cast mixed treatment than that in the control.
養液栽培 方式이 참외의 初期生育과 果實의 品質에 미치는 影響
전하준,황진규,이용세 대구대학교 과학기술연구소 1999 科學技術硏究 Vol.6 No.2
Experiments were conducted to investigate the effect of hydroponic system on the early growth and fruit quality of Cucumis melo L. var. makimw cv. Eunchun. Early growth of oriental melon in three systems of hydroponics was similar and significantly higher than in common soil cultivation but it was lowest in NFT. Early yields of oriental melon also showed similar tendency and yield per plant was the lowest in NFT. But there were no significant differences on mean fruit weight in four treatments. Diameter and length of fruit were not showed significant statistical differences. Soluble solid contents were highest in placenta of fruits grown in fertigation system. Fruits grown in perlite medium system had higher soluble solid contents than in other treatments except placenta in fertigation. These results could be apply to the practical work in hydroponic cultivation for oriental melon by examining more growth conditions.
배지의 종류가 참외의 초기생육과 수량 및 과실의 당도에 미치는 영향
전하준,황진규,이용세 대구대학교 과학기술연구소 1999 科學技術硏究 Vol.5 No.5
This study was conducted to investigated the effect of growth medium of hydroponic system on the early growth, yield and soluble solid content of fruit of Cucumis melo var. makuwa cv. Eunchun. Plant height and length of node of stem was significantly higher in soil cultivation than in perlite and cocopeat medium. So it could be done easily for pinching work of stem. And the diameter of stem was thicker in the plant grown in perlite and cocopeat medium than in soil. Yield per plant was higher in cultivated at perlite and cocopeat medium than cultivated in soil in all sampling times. Mean of fruit weight and soluble solid content were not showed significant differences in all treatment. These results could be apply to the practical work in hydroponic cultivation for oriental melon by examining more growth conditions.
