  • 최근에 농업기술의 발달로 작물의 재배환경과 재배기술 또한 날로 개선되어 가고 있으나 농촌인력의 부족과 재배자의 고령화로 인한 토양 비배 관리의 소홀, 화학 비료의 과다 및 편중 사용, 토양산도 변화에 따른 작물의 영양 흡수 불균형으로 인한 각종 생리적 장해의 발생과 하우스 재배면적의 증가로 인한 연작장해의 발생이 심각한 문제로 대두되고 있다. 본 강좌에서는 $\mathbb{\ulcorner}$영양생리 장해의 발생현황과 발생조건$\mathbb{\lrcorner}$$\mathbb{\ulcorner}$영양생리 장해의 진단$\mathbb{\lrcorner}$에 이어 작물 재배시에 발생하는 각종 $\mathbb{\ulcorner}$영양생리 장해의 대책$\mathbb{\lrcorner}$을 소개한다.

  • 포도 2기작 재배는 아열대 지방인 대만 등에서 온난한 기후를 이용하여 실시되고 있다. 최근에 와서는 일본에서도 시설내 환경조절을 통하여 거봉포도를 한 나무에서 1년에 2회 생산하는 2기작 재배가 시도되고 있다. 2기작 재배 기술이 확립되면 수익의 증가가 기대됨과 동시에 하우스의 이용효율이 높아진다. 또한 수세도 쇠약해지지 않아 정상적인 가온재배에 비해서 수세 유지가 양호하다(Yamamoto, 1993). (중략)

  • This experiment was carried out to investigate the influence of rhizome size and planting space on some agronomic characters and rhizome yield of ginger in greenhouse cultivation. The average air temperature was 9$^{\circ}C$ higher in greenhouse cultivation than in field. The average soil temperature also was 2-4$^{\circ}C$ higher in greenhouse. Plant height, leaf area, stem number and rhizome yield were significantly increased when cultivated at greenhouse compared to field. Under greenhouse the yield of rhizome in 30$\times$30cm planting space were appeared to be increase 121-183% compared with field cultivation. At the planting space of 60$\times$30cm, harvests were increased 76-82% comparing field cultivation. The most suitable rhizome size for planting at 30$\times$30cm planting space found to be 40g in greenhouse cultivation.

  • Spinach downy mildew caused by Peronospora spinaciae is the main reason of yield reduction in Korea as well as in worldwide. After forced ventilation or horizontal air circulation fans were installed to control growth conditions in green house, the changes of temperature, relative humidity (RH), growth and yield, and occurrence of downy mildew were examined. Althought here was no significant difference of temperature between the treatments, RH as 9.2% lower at nighttime by forced ventilation. In addition, final fresh weight was increased to 17.8g compared to control (10.1g), which as 7.7g enhancement. Downy mildew s tarted to show 20 days after sowing (DAS) and increased to 34.7% at 60 DAS on harvest time in control. In contrast downy mildew was occurred 40 DAS with 0.7% incidence rate and 4% at harvest by forced ventilation. The results indicated that reduction of only 9.2% of RH at nighttime by forced ventilation in greenhouse spinach growth was dramatically thrived over 76.2%. Additionally spinach downy mildew occurred 20 days later with extremely lower incident rate, which meant 88.5% reduction of downy mildew.

  • This study investigated seasonal occurrence of Frankliniella occidentalis and its damage on chrysanthemum from 1999 to 2000. F. occidentalis adults were attracted to yellow sticky traps from early April to harvesting time in the field. The highest densities were observed from late April to mid-June in spring culture and from mid-August (just after transplanting) to early September in autumn culture respectively. Seasonal fluctuation in a PVC green house was similar to that in the field. Number of insects per flower were higher in the green house than that in the field. Leaf damages due to the insects were observed from mid-May and increased as chrysanthemum grows (R$^2$ = 0.9200-0.9887$\^$**/, p> 0.01).

  • 거봉, 피오네와 같은 대립계의 4배체 포도는 소비자의 기호에 따른 소비 증가로 재배면적이 전국적으로 증가하고 있다. 대부분의 시설재배 농가에서는 단순히 숙기촉진을 목표로 한 가운데 년 1회 생산을 위한 가온재배가 이루어지고 있으므로 수확이 완료된 하우스는 거의 4∼5개월 이상 시설이 방치 상태에 있게 된다. (중략)

  • 우리 나라에서 채소 중에 가장 많은 재배면적을 차지하고 있는 고추는 대부분 노지에서 건고추용으로 재배되고 있다. 최근에 이상 기상 현상으로 고추는 강우량이 많은 해에는 습해와 병해(역병)가 발생하며 또 가뭄에 의해 생산이 불안정하다. 뿐만 아니라 생육후기의 재배관리가 미흡하여 단위면적당 생산성도 낮은 실정이며, 특히 고추의 재배지가 경사진 밭이 많아 관수를 적절히 하지 못한데서 수량의 감수요인이 되고 있다. (중략)

  • 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.
