시설원예의 급속한 증가와 더불어 시설재배에 있어서도 증수, 품질의 향상, 노동력 절감 둥의 관점에서 물관리의 중요성이 대두되고 있다. 시설재배 작물의 물관리를 합리적으로 실시하기 위해서는 시설재배에 있어서의 증발산량의 파악이 불가피한데 이에 관한 연구예는 경지의 그것에 비하여 매우 적고, 일부 실측된 예가 있으나 시설환경이나 재배방식 등을 고려하여 정량적으로 파악된 예는 거의 찾아볼수 없으며, 따라서 그것을 구명하는 것은 시설재배 작물의 소비수량 산정에 중요한 자료가 될 수 있을 것이다.(중략)

세계 최대 시설용량이며, 국내최초인 조력발전소의 마무리공정이 한창 진행되고 있는 대역사의 현장을 지난 17일 오후 2시에 찾았다. 짭쪼름한 바닷내음이 점차 진해진다 싶을 때 시야에 들어온 '청정 무공해 전력생산기지' 시화조력발전소. 발전소는 경기도 안산시 오이도와 대부도 사이를 잇는 길이 11.2Km 시화방조제 중간(작은 가리섬)에 위치한 가운데 본격가동의 카운트다운을 준비하고 있다. 지난 4월 10호기를 시작으로 6개월간에 걸친 각종 설비기능시험 등을 거쳐 오는 11월 상업운전을 통해 본격적인 전기 생산에 돌입할 예정인 시화조력발전소의 건설 의미와 주요시설 및 설비구성, 그리고 준공에 따른 기대효과 등을 조망해 본다.

최근 들어 시설재배는 토양재배에서 관비재배, 관비재배에서 양액재배방식으로 전환하려는 농가가 급속히 늘고 있어 시대가 변천하면서 더욱 생력적이고 효율적인 농업방식으로 발전하고 있다. 이는 시설의 구조나 형태가 작물생육에 적합한 환경을 제공하기 위하여 지속적으로 개선되어 왔고, 또한 토양재배시 초래되는 연작장해를 회피하기 위한 농가의 요구가 반영된 결과이다. (중략)

Number of crop residues generated at large amount in agriculture can be utilized as substrate in methane production by anaerobic digestion. Greenhouse vegetable crop cultivation that adopting intensive agricultural system require the heating energy during winter season, meanwhile produce waste biomass source for the methane production. The purpose of this study was to investigate the methane production potential of greenhouse vegetable crop residues and to estimate material and energy yield in greenhouse system. Cucumber, tomato, and paprika as greenhouse vegetable crop were used in this study. Fallen fruit, leaf, and stem residues were collected at harvesting period from the farmhouses (Anseong, Gyeonggi, Korea) adopting an intensive greenhouse cultivation system. Also the amount of fallen vegetables and plant residues, and planting density of each vegetable crop were investigated. Chemical properties of vegetable waste biomass were determined, and theoretical methane potentials were calculated using Buswell's formula from the element analysis data. Also, BMP (Biochemical methane potential) assay was carried out for each vegetable waste biomass in mesophilic temperature ($38^{\circ}C$). Theoretical methane potential ($B_{th}$) and Ultimate methane potential ($B_u$) off stem, leaf, and fallen fruit in vegetable residues showed the range of $0.352{\sim}0.485Nm^3\;kg^{-1}VS_{added}$ and $0.136{\sim}0.354Nm^3\;kg^{-1}VS_{added}$ respectively. The biomass yields of residues of tomato, cucumber, and paprika were 28.3, 30.5, and $21.5Mg\;ha^{-1}$ respectively. The methane yields of tomato, cucumber, and paprika residues showed 645.0, 782.5, and $686.8Nm^3\;ha^{-1}$. Methane yield ($Nm^3\;ha^{-1}$) of crop residue may be highly influenced by biomass yield which is mainly affected by planting density.

This experiment was conducted to investigate host preference, occurrence and intraplant distribution of Trialeurodes vaporariorum (Westwood) and Encarsia formosa (Gahan) in greenhouse. T vaporariorum preferred cucumber over tomamto. 7: vaporariorum adults distributed at upper part of cucumber plant. Nymphs also distributed at upper part in early growing stage of cucumber but became to distribute lower part after 40 days. E. formosa adults were found mainly at mid-upper part of plant but there was no significant difference in statistics all analysis among each parts and also mummy distributed mid-low part. E. formosa were released when five ir: vaporariorum were caught by yellow sticky trap per week in glasshouse. The treatment of one tag (50 mummies) of E. formosa per five plants controlled successfully the 7: vaporariorum population after 40 days.

An epidemic of target leaf spot of cucumber (Cucumis sativus) occurred in commercial greenhouses in Korea in 2000/2001. The early symptoms on the leaves were small brown spots with yellow halos. These lesions became irregular enlarging in diameter and eventually defoliation resulted. The causal agent was a fungus with morphological characteristics matching Corynespora cassiicola. The sequence of the ITS region of C. cassiicola CM2000-1 was identical to that of an authentic strain of Corynespora cassiicola. Optimal germination of spores and mycelial growth on plate was at 3$0^{\circ}C$. A long dew period on the leaf surface and high temperatures were the main contributing factors for disease development and the greenhouse epidemic. Artificial inoculation of the Korean isolate of C. cassiicola revealed resistance in some Korean cucumber cultivars.

The contents of total phenolics and flavonoids, antimicrobial and tyrosinase inhibition activities of five growth stages with four greenhouse-grown cucumber extracts were investigated. Total phenolic content was high in Jangjukcheongjang, Janghyeongnakhap and five growth stage(24~27 cm). The content of total flavonoid did not differ between cultivar or growth stages. Among the four cucumber cultivars, the extract of Janghyeongnakhap showed a relatively strong antimicrobial effect against Staphylococcus aureus. The inhibition zone against Staphylococcus epidermidis of the samples tested in this experiment was 8~12 mm. And the antimicrobial effects against Malassezia furfur was high in Jangjukcheongjang, and showed the highest by the inhibition zone of 14mm in three(17~20 cm) growth stage. The tyrosinase inhibition activity of cucumber extracts showed relatively high activity in Jangjukcheongjang and Sinjoeunbaekdadagi, followed by Janghyeongnakhap. From these results, we confirmed that the extract of cucumber has high antimicrobial and whitening efficacy, and that in the future, the cucumber will be increase the availability in the field of high-value cosmetic materials.
