The purpose of this study was to evaluate the control efficacy of major environment-friendly control agents against powdery mildew, as affected by the application condition such as disease-developing stage and microclimate,as compared with the efficacy of pesticides in plug seedling of three Cucurbitaceae vegetables, including cucumber, melon, and oriental melon. Single or combined application of major six environment-friendly control agents was used in the experiment: two biofungicide (Ampelomyces quisqualis 94013 and Bacillus subtilis Y1336),two plant extracts (neem oil and extracts of Rheum undulatum), and two mineral materials (wettable sulfur powder and lime bordeaux mixture). These control agents were treated to the plug seedlings for preventing powdery mildew and curative applications for managing powdery mildew. In all treatments, the disease incidence declined as daily average temperatures increased to 30oC for consecutive 6~8 days with maximum temperature over 40oC. In preventative application, the control efficacy against powdery mildew was the highest in the treatment of wettable sulfur powder, and lowest in the B. subtilis Y1336, with values of 20~40%. In cucumber seedlings, the preventive single application of neem oil or wettable sulfur powder was more effective than curative application of fungicides, while the control efficacy of these agents was similar to those of fungicides in melon seedlings. The single application of R. undulatum extracts was also effective in preventing the disease for both cucumber and melon seedlings, showing a higher control efficacy than those of biofungicides during seedling stage. The treatment of water spray was not effective and showed a higher disease incidence than the untreated control plot in the oriental melon and melon seedlings. The curative application with environment friendly control agents, after powdery mildew was first detected, could not successfully controlled the disease at the middle stage (5~10% of disease incidence) of disease development. The curative combined application of [R. undulatum extracts (1st application) + wettable sulfur powder (2nd) + neem oil (3rd)] showed the highest control efficacy among the other treatments, with control value over 80% at the early stage (less than 1% of disease incidence) of disease development. 본 실험은 박과류(오이, 참외, 멜론)를 공시작물로 하여친환경 육묘시 친환경 제제와 시용조건에 따른 흰가루병의 방제효과를 구명하고 기존 등록된 농약과 대조하여그 효과를 검정하기 위해 수행되었다. 친환경제제는 유효미생물로서 Ampelomyces quisqualis 94013(AQ94013)과Bacillus subtilis Y1336(BS Y1336), 식물추출물로서 님오일(Neem oil)과 대황(Rheum undulatum)추출물, 미네랄제제는 황수화제와 석회보르도액(Lime Bordeaux mixture)을 단용 또는 혼용처리하여 병 발생시기(발생전, 초기,중기)에 따라 처리하였다. 모든 처리구에서 시설내 일평균온도 30oC 이상, 하루 중 최고기온이 40oC 이상의조건이 일주일 이상 지속되는 기간 동안 유묘의 흰가루병의 발병도는 감소하였고, 대조구인 무처리구에서의 발병도도 크게 감소되어 10% 미만으로 나타났다. 발생 전처리시 방제효과는 모든 작물에서 황수화제가 가장 높았고, BS Y1336는 방제가가 20~40%로서 가장 낮게 나타났다. 오이의 경우 발생전 처리시 님오일과 황수화제 처리는 살균제보다 높은 방제효과를 보였으며, 멜론에서는농약과 비슷한 방제가를 보였다. 대황추출물은 전 생육기간 동안 미생물제제보다 높은 방제가를 나타내었고,오이와 멜론작물에서 발생초기 처리시 효과가 우수하였다. 물살포구는 무처리구와 비슷한 발병도를 보여 방제효과가 없었고, 참외와 멜론에서 물살포 처리는 무처리보다 더 높은 발병도를 보였다. 병발생후 친환경제제 처리시 방제효과는 처리하는 시기가 늦어질수록 감소하였다. 친환경제제의 혼용처리에 의한 방제효과를 조사하였을 때, 대황추출물(1주차) + 황수화제(2주차) + 님오일(3주차)의 조합으로 한 가지의 친환경제제를 주당 1회씩총 3주 동안 혼용처리 했을 때, 전 육묘기간 동안 오이에서는 90% 이상, 모든 작물에서 평균 80% 이상의 방제가를 나타내어 다른 조합의 처리에 비해 높은 방제효과를 보였다. 본 실험결과를 통해 박과채소의 친환경 육묘시 흰가루병에 대한 친환경제제의 방제효과는 단용처리 했을 때, 병발생 전후 처리에 상관없이 모든 작물에서 황수화제 처리가 가장 높게 나타났으며, 혼용처리시에는 대황추출물(1주차) + 황수화제(2주차) + 님오일(3주차)의 조합이 가장 효과가 높은 것으로 나타났다.

본 연구는 고온기 원예작물의 안정 생산을 위해 대형 단동하우스 '사계절하우스'를 파프리카 재배에 활용 시 시설 내부 기상환경 및 파프리카 품종별 생육, 수량, 품질 등을 분석하고 근권냉방 효과 등을 구명하여 파프리카 재배환경 조건을 최적화 하기 위한 기초자료로 사용하고자 수행하였다. 정식 후부터 재배 종료 시점(2020년 5-11월)까지 시설내 평균 적산광량은 12.7MJ·m^-2d^-1로, 온실외부의 평균 광량인 14.1MJ·m^-2d^-1의 90% 수준으로 나타났다. 일 년중 가장 기온이 높은 7-8월의 온실내 24시간 평균온도는 외기보다 3.04℃ 낮았고, 장마가 끝난 8월 12일 이후에는 평균 4.07℃ 낮게 나타났다. 시설 내 포그 냉방 가동(6월 13일) 이전 일평균 상대습도는 최저 40%(주간 20%) 수준까지 떨어져 작물재배에 적합하지 않은 상태였으나 포그를 가동한 이후 주간 상대습도는 70-85% 수준으로 증가된 것으로 나타났다. 평균 수분부족분(humidity deficit)은 포그 공급전에는 최고 12.7g/m³ 까지 상승하여 매우 건조한 조건이었으나, 포그 공급 후 고온기(7-8월)에 평균 3.7g/m³으로 감소하였고, 저온기(10-11월)로 갈수록 다시 증가되는 경향이었다. 주간 잔존 CO₂ 농도는 전체 재배기간동안 평균 707ppm으로 나타났다. '20년 7월 27일부터 11월 23일까지 수확한 파프리카의 품종별 상품수량(kg/10a)은 주황색 품종 'DSP-7054'과 황색 품종 'Allrounder'이 각각 14,255kg/10a와 14,161kg/10a로 다른 품종에 비해 높았고, 다음으로 주황색 'K-Gloria orange', 황색 'Volante', 적색 'Nagano' 품종 순으로 나타났다. 사계절하우스에서 고온기(8월)에 생산된 대과종 파프리카의 품종별 과실품질 특성을 조사한 결과, 과고, 과폭, 과실당도, 과육두께에서 품종 간 유의성이 인정되었다. 당도는 주황색 품종인 'DSP-7054'와 'Naarangi'에서 높게 나타났고, 과육두께는 황색과 주황색 품종인 'K-Gloria orange'와 'Allrounder'에서 높게 나타났다. 근권 냉방처리 기간 동안 배지내 일평균 온도는 20.7℃로 나타났고, 근권 난방처리 기간 동안 배지내 일평균 온도는 23.4℃로 나타났다. 근권부 냉난방 처리를 통해 상품수량은 무처리구에 비해 비해 'Nagano' 16.5%, 'Allrounder' 1.3%, 'Naarangi' 20.2%, 및 'Raon red' 17.3% 증가하였고, 품종 전체로는 16.1% 증가하였다. 근권 냉난방처리에 의해 과실의 경도는 4개 품종 평균 5.7% 증가하였으나 다른 품질 지표에서는 유의성있는 차이가 나타나지 않았다. During the growing period, the integrated solar radiation inside the greenhouse was 12.7MJ·m^-2d^-1, and which was 90% of the average daily global radiation outside the greenhouse, 14.1MJ·m^-2d^-1. The 24-hour average temperature inside the greenhouse from July to August, which has the highest temperature of the year, was 3.04℃ lower than the outside temperature, and 4.07℃ lower after the rainy season. Before the operation of fog cooling system, the average daily RH (%) was lowered to a minimum of 40% (20% for daytime), making it inappropriate for paprika cultivation, but after the operation of fog system, the daily RH during the daytime increased to 70 to 85%. The average humidity deficit increased to a maximum of 12.7g/m³ before fog supply, but decreased to 3.7g/m³ between July and August after fog supply, and increased again after October. The daytime residual CO₂ concentration inside the greenhouse was 707 ppm on average during the whole growing period. The marketable yield of paprika harvested from July 27th to November 23rd, 2020 was higher in 'DSP-7054' and 'Allrounder' with 14,255kg/10a and 14,161kg/10a, respectively, followed by 'K-Gloria orange', 'Volante' and 'Nagono'. There were significant differences between paprika cultivars in fruit length, fruit diameter, soluble solids (°Brix), and flash thickness (mm) of paprika produced in summer season at large single-span plastic greenhouse. The soluble solids content was higher in the orange cultivars 'DSP-7054' and 'Naarangi' and the flesh thickness was higher in the yellow and orange cultivars, with 'K-Gloria orange' and 'Allrounder' being the thickest. The marketable yield of paprika, which was treated with cooling and heating treatments in the root zone, increased by 16.1% in the entire cultivars compared to the untreated ones, increased by 16.5% in 'Nagano', 10.3% in the 'Allrounder', 20.2% in the 'Naarangi', and 17.3% in 'Raon red'.

Optimal Levels of N, P, and K for the Cultivation of Single-stemmed Roses in a Closed Hydroponic System

여경환,최기영,이한철,최경이,이용범 한국원예학회 2016 Horticulture, Environment, and Biotechnology Vol.57 No.6

It is necessary to identify the optimum levels of mineral nutrients for the commercial production of single-stemmed roses in a closed hydroponic system to avoid the accumulation of undesirable ions in the root zone and to improve shoot growth and flower quality. We determined the optimal concentrations of nitrogen (N), phosphorous (P), and potassium (K) in a nutrient solution by analyzing the amount of mineral nutrients absorbed by the plant, plant growth, and photosynthesis characteristics. Rose plants (Rosa hybrid L. cv. Red Velvet) were subjected to different concentrations of macronutrients, including N (0, 10, 50, 100, 150, or 200 mg·L-1), P (0, 10, 20, 40, 80, or 100 mg·L-1), and K (0, 10, 50, 100, 150, 200, or 250 mg·L-1). The uptake of nitrate-N (NO3-) was inhibited by high P levels, and the NO3-N concentration in the nutrient solution was significantly higher in the 100 mg·L-1 P treatment than in the other P treatments, indicating reduced NO3- uptake by the plants. The concentration of phosphate (PO4-) decreased considerably in all N and K treatments during the entire growth period. To ensure a sufficient supply of P for single-stemmed roses, it is necessary to increase the PO4- concentration in the nutrient solution. Increasing the K+ level significantly increased the concentrations of calcium (Ca2+) and magnesium (Mg2+) in the nutrient solution. This may be the result of low Ca and Mg absorption from plants over the growth period. Although there was an increase in the fresh weight and stem length with higher levels of N [NO3-and ammonium (NH4+)], PO4-, and K+, growth did not significantly increase at levels higher than 150 mg·L-1 N, 40 mg·L-1 P, and 200 mg·L-1 K treatments. The photosynthetic rates (Pn) increased rapidly as the concentration in the nutrient solution increased to 100 mg·L-1 N, 40 mg·L-1 P, and 150 mg·L-1 K, followed by a reduction as the ion concentrations increased to the maximum ranges. A distinct reduction of the Pn was observed in the plants supplied with nutrient levels above 150 mg·L-1 N, 80 mg·L-1 P, and 200 mg·L-1 K. Considering the nutrient-water absorption patterns, growth, and photosynthesis characteristics of single-stemmed roses, the mineral nutrient levels of 100–150 mg·L-1 N, 30-50 mg·L-1 P, and 100–150 mg·L-1 K were found to be optimal for the production of single-stemmed roses in a closed hydroponic system.

Determination of Optimal Levels of Ca and Mg for Single-stemmed Roses Grown in Closed Aeroponic System

여경환,이주현,이용범 한국원예학회 2013 Horticulture, Environment, and Biotechnology Vol.54 No.6

In the production of single-stemmed roses in a closed system, it is necessary to identify the optimal ranges of ions in the nutrient solution in order to determine the optimal management practices for the crop. This study was conducted to determine the optimal levels of Ca 2+and Mg 2+in the nutrient solution for optimization of nutrition of single-stemmed roses grown in a closed aeroponic system. Single-stemmed roses were grown in the nutrient solution with 7 different levels each of Ca (0, 10, 40, 80, 120, 160, and 200 mg·L -1) and Mg (0, 10, 20, 40, 80, 120, and 160 mg·L -1) for four weeks after transplanting. A sharp pH change was observed in the treatments with low levels of Ca 2+and Mg 2+during the first and second weeks after transplanting, and there was a stable variation in EC in a range of 1.3-1.8 dS·m -1in the treatments of 40-120 mg·L -1Ca and 10-80 mg·L -1Mg. Contents of Ca and K contents in leaf tissue were significantly decreased by increasing Mg 2+level in the nutrient solution. Although there was an increase in the fresh weight and stem length under higher levels of Ca 2+and Mg 2+, plant growth did not increase as compared to the treatments of 120 mg·L -1Ca and 80 mg·L -1Mg. Photosynthetic rate in the leaves of flowering shoots was the greatest in the range of 80-120 mg·L -1Ca, and the stomatal conductance and transpiration rate had a tendency to increase along with the increase of Ca 2+concentration up to 120 mg·L -1before distinct decrease at Ca 2+level greater than 160 mg·L -1. In Mg treatments, photosynthetic responses showed maximum values at around 40-80mg·L -1, and began to decrease at level greater than 80 mg·L -1. Photosynthetic water use efficiency (WUE) was lower in leaves of the treatments of 160 and 200 mg·L -1Ca, and 0 and 160 mg·L -1Mg. Chlorophyll content in five-leaflet leaves as influenced by Mg 2+level tended to increase continuously up to 80 mg·L -1, showing a positive correlation with Mg content in the leaves. Content of anthocyanin in five-leaflet leaves was higher in the treatments with low Mg 2+levels (0 and 10 mg·L -1). Considering the nutrient and water absorption patterns, and growth characteristics of single-stemmed roses with different solution Ca 2+and Mg 2+levels, 80-120 mg·L -1Ca and 30-80 mg·L -1Mg seem to be appropriate for the optimization of plant nutrition in a closed production system.

Estimation of Growth and Yield for Single-stemmed Rose ‘Vital’ in a Single Stem System

여경환,조영열,이용범 한국원예학회 2011 Horticulture, Environment, and Biotechnology Vol.52 No.5

In ornamental crop production, growth models as a function of environmental factors can be used as a valuable tool for predicting the timing of a phenological event for the average of a population, for the optimization of environmental conditions inside a growing system, and for making cultural decisions for increasing crop production. The feasibility of an expolinear growth equation was evaluated by predicting the crop growth of single-stemmed rose ‘Vital’ in a single stem system using recirculating nutrient solution. The objectives of this study were to determine a suitable environmental variable and growth parameters, i.e. maximum crop growth rate (C_m), maximum relative growth rate (R_m), and the lost time (t_b) for expolinear growth equation using biomass data obtained from 4 experiments with different seasons [cut on Oct. and Nov. in 2004 (Expts. 1 and 2), and Apr. and Jun. in 2005 (Expts. 3 and 4)] and then to predict the crop growth based on an empirical model as a function of the environmental variable and plant density (plants/m2) using estimated parameters of the expolinear growth equation. The growth parameters were estimated by fitting the expolinear growth equation as a function of time, thermal units (TUs, ℃・d),or daily incident photosynthetically active radiation (PAR, MJ・m^(-2)・d^(-1)) to observed the biomass per unit area (m^2) using a nonlinear regression procedure with Gauss-Newton method. The use of TUs as a variable of expolinear growth equation improved the accuracy of the model and gave a better estimate of growth parameters as compared with those of time or incident PAR integral. Although the fitted expolinear growth equation effectively described the measured fresh and dry mass per unit area, we concluded that TUs was an appropriate variable of expolinear growth equation for single-stemmed rose ‘Vital’ considering some advantage, such as a cheap and easy way for growers to measure the microclimate inside a greenhouse for cut-flower rose production. This study also investigated the effects of TUs and plant density (67, 89, and 107plants/m^2) on the growth of single-stemmed rose ‘Vital’ in a single stem system by adjusting the expolinear equation. The growth parameters, C_m, R_m, and t_b were estimated by fitting the expolinear growth equation to the measured dry mass measurements obtained from 3 experiments (Expts. 1, 2, and 3) at three different plant densities. Parameters C_m and t_b showed a curvilinear relationship with plant density over three experiments and were fitted to the quadratic function. The R_m was substituted with the mean value of the estimated values at each plant density, 0.0082, because there were no significant differences in R_m values among plant density treatments. The estimation of dry mass per unit area by the expolinear growth equation as inputs of TUs and plant density agreed well with the validation data, but the model tended to overestimate dry mass per unit area. The measured dry mass showed a linear relationship with fresh mass regardless of plant densities. The shoot fresh mass per m2 was estimated by an empirical relationship between shoot fresh mass and dry mass using the estimated shoot dry mass. The estimated and measured shoot dry mass and fresh mass showed a reasonably good fit with 1.142 (R2 =0.988) and 1.168 (R2 = 0.976), respectively.

Optimal Plant Density for Single-node Cutting Roses ‘Vital’ and ‘Red Velvet’ in a Plant Factory

여경환,이용범 한국원예학회 2008 Horticulture, Environment, and Biotechnology Vol.49 No.5

The design of an industrial crop production system, such as a plant factory should optimize plant spacing, which should closely match the natural growth rate. This study was conducted to analyze the variation in growth and yield of single-node cutting (SNC) roses ‘Red Velvet’ and ‘Vital’ as influenced by plant density in a factory-type rose production system. The plants were grown at 7.5 and 10 cm between-row plant spacings and at three within-row plant spacings: 133 plants/m2 (7.5×10 cm), 107 plants/m2 (7.5×12.5 cm), 89 plants/m2 (7.5×15 cm), 80 plants/m2 (10×12.5 cm), 67 plants/m2 (10×15 cm), and 57 plants/m2 (10×17.5 cm). Leaf area (LA), crop growth rate (CGR), and specific leaf area (SLA) were calculated by using shoot fresh weight, shoot dry weight, and leaf area. Plant density had a significant effect on the quality of SNC roses. Flower shoot length, stem diameter and number of petals decreased as plant density increased. In addition, fresh and dry weight per plant decreased with increasing plant density, while yield per area increased except for the plant density of 133 plants/m2 (7.5×10 cm) and 107 plants/m2 (7.5×12.5 cm). When the growth characteristics were analyzed of ‘Red Velvet’ and ‘Vital’, the highest productivity was shown in the treatment of 89 plants/m2 (7.5×15 cm). The most effective and optimal range of plant density for the highest marketable yield was indicated as 107 plants/m2 (7.5×12.5 cm) ~ 89 plants/m2 (7.5×15 cm) for actual growing in a plant factory system.

본 실험은 thermal units을 이용하여 single-stemmed rose($Rosa$ $hybrida$ L.) 'Vital'의 초장, 생체중 및 총엽면적과 각 생육단계에 도달하는 시간을 예측하고, 장미의 신초발달 모델을 개발하기 위해 수행하였다. 기저온도($T_b$), 적정온도($T_{opt}$), 및 최대온도($T_{max}$)는 신초의 발달율과 평균온도의 회귀를 통해 예측하였다. 삽목에서 정식(CT-TP)까지의 생육단계에 대한 신초의 발달율은 linear 함수인 $R_b(d^{-1})$ = -0.0089 + $0.0016{\cdot}Temp$으로 나타났다. 정식에서 수확(TP-HV)까지의 생육단계에서 신초의 발달율은 parabolic 함수인 $R_h(d^{-1})$ = $-0.0001{\cdot}Temp^2$ + $0.0054{\cdot}Temp$ - 0.0484으로 나타낼 수 있었다. $T_b$, $T_{opt}$ 및 $T_{max}$는 각각 5.56, 27.0, 및 $42.7^{\circ}C$으로 나타났다. Tb값 $5.56^{\circ}C$은 single-stemmed rose의 신초발달에 대한 온도함수인 thermal units 계산에 이용되었다. 엽수, 엽면적 및 엽중은 삽목시기에 상관없이 sigmoid curve를 나타내었다. 엽면적(LA) 모델은 thermal units를 사용하여 sigmoid 함수, LA = 578.7 $[1+(thermal units/956.1)^{-8.54}]^{-1}$로 기술할 수 있었다. 삽목에서 정식(CT-TP)과 정식에서 수확(TP-HV)까지의 생육단계에 있어서 요구되는 평균 thermal units($^{\circ}C{\cdot}d$)는 각각 $426{\pm}42(^{\circ}C{\cdot}d)$과 $783{\pm}24(^{\circ}C{\cdot}d$)였다. This study was conducted to predict number and fresh weight of leaves, and total leaf area of a single-stemmed rose 'Vital' based on the accumulated thermal units, and to develop a model of shoot development for the prediction of the time when the flowering shoot reaches a phenological stage in a plant factory system. The base temperature ($T_b$), optimum temperature ($T_{opt}$), and maximum temperature ($T_{max}$) were estimated by regressing the rate of shoot development against the temperature gradient. The rate of shoot development ($R$, $d^{-1}$) for the phase from cutting to bud break (CT-BB) was best described by a linear model $R_b$ ($d^{-1}$) = -0.0089 + $0.0016{\cdot}temp$. The rate of shoot development for the phase from bud break to harvest (BB-HV) was fitted to the parabolic model $R_h$ ($d^{-1}$) = $-0.0001{\cdot}temp^2$ + $0.0054{\cdot}temp$ - 0.0484. The $T_b$, $T_{opt}$, and $T_{max}$ values were 5.56, 27.0, and $42.7^{\circ}C$, respectively. The $T_b$ value was used in the thermal unit computations for the shoot development. Number of leaves, leaf area (LA), and leaf fresh weight showed sigmoidal curves regardless of the cut time. The shoot development and leaf area model was described as a sigmoidal function using thermal units. Leaf area was described as LA = 578.7 $[1+(thermal units/956.1)^{-8.54}]^{-1}$. Estimated and observed shoot length and leaf fresh weight showed a reasonably good fit with 1.060 ($R^2=0.976^{***}$) and 1.043 ($R^2=0.955^{***}$), respectively. The average thermal units required from cutting to transplant and from transplant to harvest stages were $426{\pm}42^{\circ}C{\cdot}d$ and $783{\pm}24^{\circ}C{\cdot}d$, respectively.
