Multi Cultivation Remote-control System(MCRS) for crpos through characteristics of multi-safe sensors was realized. It was carried out to investigate into the effect of LED Control with the physiological activity of crops(for examples, sprouts). We have also composed a Combined Automatic Control System possible for the control of temperature and humidity at the same time. The applied multi-safe sensors for measurement are blue, green, red, white, yellow leds and humidity sensors, web camera sensors under safe conditions for crops cultivation. And we producted the remote control OS using Linux and defined the characteristics of automatic control about sprouts.

In order to develop a smart cultivation facility based on ICT (Information Communication Technology), a cultivation house was selected. Sensor devices were installed to monitor any changes in the cultivation environment. A control panel was constructed to monitor and control the data on environmental changes collected by the sensors. To efficiently manage the proceedings of the cultivation environment, the cultivation process was divided into 4 stages. We designed an environmental control module using these processes. PC and mobile phone software were designed for remote monitoring and control to develop a smart cultivation system that can conveniently manage the cultivation environment and produce mushrooms in a more stable manner.

This study was conducted to reduce the phenomenon of biased cultivation and to pursue the diversification of mushroom items. We focused on developing Sparassis latifolia varieties with a short cultivation period, stable pinheading, and a high yield. We have collected and determined the characteristics of genetic resources domestically and abroad since 2016. We bred the unique domestic variety, "Hanyeoul" and the results of this study are as follows. The optimal temperatures for mycelial growth and fruit body growth were 22~25℃ and 19~21℃, respectively. The color of the pileus was pale-yellowish white, which was similar to the color of the control variety, "Neoul". The number of days required for cultivation was 125 for bottle cultivation and 98~102 for bag cultivation, which was shorter than the number of days required for the control variety. Bottle cultivation took 39 days shorter for the new variety than the control variety. The fruiting body of the new variety was similar in size or larger than that of the control variety. The pinheading rate was more than 90% in bottle cultivation and bag cultivation, which was more stable than pinheading in the control variety. The yield was 79.1 g/bottle (1,100 cc) for bottle cultivation, which was 22.6% higher than the yield of the control variety, and 641.1~689.5 g/bag (2.6 kg) for bag cultivation, which 5.8~10.4% higher than yield of the control variety.

The importance of plant factory which blend agriculture and manufacture has been discussed widely. This company has researched hydroponics technique for cultivation which has been mainly developed in the sites of Okinawa and Hyougo Prefecture. In 1987, we stopped the previous research there, and started a new one far plant factory at the Agricultural Research Center of Chiba Prefecture. In 1989, we built four experimental plant factories (120㎡) at Chiba Oil Factory Refinery in Ichihara-city, developing techniques of cultivation, equipment production and environmental control for cultivation system of tomato, strawberry and leaf vegetables.

Crop protection strategies in organic horticulture aim to prevent insect pest and plant disease problems through utilization of non-chemical based control means. In order to develop a model for management of plant diseases and insects in organic cucumber cultivation, we compared efficacies between chemical pesticide spraying system and biological control means in semi-forcing and retarding cucumber cultivation during 2005 and 2006. Conventional chemical spray program using various chemical pesticides was applied 5 - 10 days intervals, while two different non-chemical pesticide application programs using two formulated biopesticides Topseed$^{TM}$ and Q-fect$^{TM}$, Suncho$^{TM}$, and Sangsungje$^{TM}$ (biocontrol agents 1) and using egg-yolk and cooking oil(EYCO), Bordeaux mixture, Suncho$^{TM}$, and Sangsungje$^{TM}$ (biocontrol agents 2) were applied 5 - 7 days intervals during entire cucumber cultivation period. Efficacy of both biocontrol agents programs was effective to comparable to conventional chemical pesitice spray program to control plant diseases such as powdery mildew and downy mildew as well as insect pests such as aphids and thrips which are known as major threats in cucumber organic cultivation. In this study, we established and evaluated an effective and economic crop protection strategy using various biological resources can be used to control plant diseases and pests simultaneously in organic cucumber cultivation field.

우리나라에서 사용되고 있는 원예시설 피복자재는 대부분 PE (polyethylene), EVA(ethylene vinylacetate)와 PVC (ployvinychloride) 등의 플라스틱 연질필름을 소재로 되어있다. 이러한 연질 피복자재는 광투과율, 내구성, 그리고 장파방사 측면에서 불리한 조건을 가지고 있다. 또한 연질필름의 기능성 가운데 분쟁의 소지가 많은 방적성을 현장에서 개선하기 위해서는 단순하면서도 경제적인 방법이 요구된다고 하겠다. (중략)

우리나라 시설원예 면적은 '95년 43,093ha에서 '01년 말 현재 52,125ha로 연평균 3.2%의 증가율을 보인 반면 난방면적은 연평균 10.8%씩 증가하여 12,710ha로 전체 시설재배 면적의 24.4%를 차지하고 있다. 또한 난방연료의 95% 이상이 경유이며, 최근 국제정세 불안 등으로 유가가 급등하여 시설재배농가의 연료비 부담은 더욱 가중되고 있다. (중략)

우리나라 전체 시설원예 면적 52,135ha(2001년) 중 난방을 하고 있는 시설원예 면적은 12,710ha로서 약 24%정도를 차지하고 있다. 시설재배면적의 지역분포를 비교해 보면, 시설채소의 경우 중부 이북지역에 44%, 남부에 56%의 비율로 분포해 있으며, 시설화훼의 경우 중부 이북 58%, 남부 42%로서 난방비가 많이 소요되는 지역이라도 수도권을 중심으로 유통이나 지리적 면에서 유리한 지역에 시설재배면적이 많이 분포해 있다. (중략)
