  • 1. 고추 무농약재배 비가림 시설재배 효과 무농약 고추 노지 터널재배와 비가림 재배의 수량성을 검토하고, 관행 비가림 시설에 측고와 동고를 높이고 가로대를 보강하여 최소한의 투입으로 작물재배 환경을 개선으로 농작업에 편리성을 도모하고자 시험을 수행한 결과 비가림 시설재배가 노지 터널재배에 비하여 생육이 양호하고. 수량이 2배정도 많았다. 노지재배 고추는 강우로 인하여 탄저병이 40% 정도 발생되었으나, 비가림 시설재배는 탄저병과 역병이 전혀 발생되지 않았다. 2. 고추 비가림 시설 환경 개선 효과 구명 비가림 시설의 측과와 동고를 높이는 간단한 환경개선으로 여름철은 시설내 온도가 관행 비가림 시설보다 낮아지는 효과가 있었다. 또한 비가림 시설환경 개선에 의해서 "녹광" 풋고추의 생육은 증가되었으며, 홍고추 "조양" 품종도 같은 경향이었다. 고추의 수량은 풋고추 "녹광" 품종이 홍고추 "조양" 품종보다 수확량이 현저하게 많았고 처리간에는 비가림 시설의 환경을 개선한 시설이 관행 비가림 시설에 비하여 증수되었다. 그리고 비닐온실의 측고를 높인 결과 비닐 온실 내 측면으로 사람의 통행이 자유로워 작업환경 도도 개선되었다.

  • This study was compared to outdoor field (OF) and rain shelter greenhouse (RSG) according to cultivation type of Gastrodia elata Blume. Also, the effects of yield and quality for mulching materials in RSG were compared. The yield of G. elata was investigated good merchantable quality, and the quality was investigated hardness, chromaticity, weight loss and the contents of the major functional components. The cultivation of RSG was increased the yield, hardness, gastrodin, and vanillyl alcohol compared to OF, and the weight loss, chromaticity, and ergothioneine were almost equal. Rice straw treatment showed higher than those of the control and other treatments on the yield and hardness. As a result, the yield and the quality of RSG, which can control the soil moisture, were better than that of OF. And the lower the soil moisture content according to the mulching material, the harder the surface and the higher the hardness.

  • This experiment was carried out to investigate the effect of rain shelter cultivation on growth characteristic and yield on Paeonia lactiflora Pallas. The sprouting time and flowering time of rain shelter cultivation were 9days and 15days, more quickly than that of field conditions, and stem length and number of stem per plant were many more or larger. The disease occurrence rain shelter cultivation was decreased of rust, anthracnose, powdery mildew and root rot disease compared to field conditions, and leaf spot disease was to similar. The root length, number of root and root diameter were to be good in the rain shelter cultivation. Root color and commercial ratio of rain shelter cultivation were better lighten and improved than field cultivation. Root yield of rain shelter was 2,395kg/10a, this was increased 9% and 27% respectively, compared to 2,201kg/10a, 1,892kg/10a of field A and field B.

  • This experiment was carried out to investigate the effect of rain shelter cultivation on the its quality of safflower. The development and growth of safflower, especially the number of secondary branches per plant was increased by rain shelter. Under the rain shelter started earlier, the seed yield was increased by 95% compared with that of non-shelter condition. The number of plants in a unit area the number of flower buds and seeds per plant and seed weight were increased in rain shelter condition. As those plants were cultivated under the rain shelter, lightness(L) of their seeds was increased but redness (a) and yellowness (b) were decreased.

  • Growth and tuber development of ‘Black Magic’calla lily as affected by the rain shelter with 50% shading and the tuber size were investigated. Tubers of five grades in size were cultivated in the rain shelter or in the open field (control). Days to emergence of shoots in the rain shelter was accelerated by 4.2 days as compared to the open field. Emergence ratio was higher as the tuber was larger, tubers grown in the rain shelter showed the significance in the growth characteristics as compared to the control. There were no significant differences in the number of flowers per tuber between the rain shelter and the open field. Flower quality was 12.2 cm longer than that in the open field. flowering characteristics was improved with the increasing tuber size. Low infection of soft rot disease of 3∼22% was found in the rain shelter as compared to the that of 19∼83% in the open field. Thus tubers produced under the rain shelter showed improved quality, Even if the small tubers with diameters of 0.5∼1.0 cm were cultivated in the rain shelter, the weight and diameters of tuber harvested after approximately 7 months were 50.2 g and 5.7 cm, respectively.

  • The physico-chemical properties of the rainfall interception culture (85 sites) and the open field culture soils (85 sites) in the area of Gochang-gun, Jeollabuk-do were surveyed. Soil textural distribution of the rainfall interception culture and the open field culture soils was 74% and 64% for silt loam, 16% and 35% for loam, and 10% and 1% for clay, respectively. The percentage of aggregate rates was higher in the open field culture soils (60.06%) than rainfall interception culture soils (55.84%). Electrical conductivity, exchangeable cations, and anions in the rainfall interception culture soils were higher than those in open field soils. Specially, accumulated amount of anion in rainfall interception culture soils was remarkably higher 2~3 times than open field culture soils. The results from the analyses of rainfall interception culture soils suggested that the most critical problem is the salts accumulation caused by over-fertilization of chemical fertilizer and compost. Therefore, application rates of chemical fertilizer and compost should be controlled in order to conservation of soil and water for sustainable agriculture.

  • Asparagus varieties popular in the foreign countries were collected and tested on their productivities and qualities for five years under rain shelter and open field conditions. Among the tested varieties, cultivars of UC309 and Excel showed superior productivity to the others in spear weight but the initial growth was not different among the tested varieties. However, the growth index was higher than the other varieties. According to the result from eight-year experiment, the best variety in productivity and quality were UC309 and Excel both for rain shelter and open field cultivations. To avoid the damage caused by stem blight, rain shelter and soil surface mulching treatments were tested with var. Excel. The spear sprouting and first harvesting date were a few days earlier in rain shelter cultivation than in open field, but there were no differences among the mulching materials. The number of spears and the spear weight per plant were increased in rain shelter cultivation, especially with rice straw and black P.E. mulching treatments. Marketable yield also increased by 253% in black P.E film mulching in rain shelter cultivation compared to non-mulching in open field. The stem blight examined in the autumn, 1997 was not observed under rain shelter treatment, but severe damage was observed in the open field regardless of the mulching materials. In the experiments, high asparagus yield could be achieved by black P.E. film mulching in rain shelter cultivation without the occurrence of stem blight.

  • This study was conducted to investigate the plant growth and seed yield between rain-shelter plastic house and out-door cultivation, and analysed the effect of harvesting time on seed quality. In rain-shelter plastic house cultivation, emergence date was 3 days and flowering date was 8 days earlier than out-door cultivation. Seed yield of rain-shelter plastic house cultivation was increased $25\%$ compared to out-door cultivation and it's more beneficial than out door cultivation. The crude fat content was higher and seed was whiter and better quality in rain-shelter plastic house cultivation than out-door cultivation. In out-door cultivation, the crude fat content was steadily increased until 40 days after full bloom, but the seed color was getting dark which was harvested at 30 days after full bloom and the color was turn to the dark brown when the seed was harvested at 40 days after full bloom. Harvesting of safflower seed's quality is best between 20 days and 30 days after full bloom.

  • The residual patterns of azoxystrobin and cyenopyrafen were investigated to compare the differences between rainshield and plastic house conditions of the grapes. Initial residue concentrations of azoxystrobin were $0.54\;mg{\cdot}kg^{-1}$ under rainshield condition and $0.9\;mg{\cdot}kg^{-1}$ under plastic house condition. And cyenopyrafen was 0.55 and $0.64\;mg{\cdot}kg^{-1}$ respectively. Biological half-life of azoxystrobin was calculated as 13.28 days under rainshield and 15.58 days under plastic house condition. And cyneopyrafen was 7.99 and 12.65 days, respectively. In comparison with two different cultivation conditions, pesticides in/on the grape were decomposed more faster under plastic house than rain shield conditions.
