JA Saga Ogi Taku Greenhouse Satsuma Mandarin Subcommittee has started shipping 2022 Greenhouse oranges at the JA Wide Area Ogi-Taku Satsuma Mandarin Fruit Sorting Plant from April 27, 2022. After sorting the Greenhouse oranges collected from the producers, they were packed by the fruit sorting employees and shipped to markets such as Osaka and Keihin districts. The 2022 production had good germination and flowering, and it seems that the subsequent growth was also going well. Blessed with the weather of menstrual fruit drop, the fruiting was also good. Both quality and appearance were good, and the production volume was expected to be 145 tons. In the future, the subcommittee will endeavor to harvest in a timely manner because there is concern about floating skin due to the high temperature during the day. I heard that they worked on controlling pests such as slips, delivered high-quality Greenhouse oranges to consumers, received confidence again, and made more fans. Agriculture requires multiple abilities. The environment surrounding abnormal weather and changes in international affairs is harsh, but the government will provide as much support as possible. At the beginning of June 2022, the completion ceremony of JA Saga Midori District Training Farm was recently held, and it seems that JA in Takeo City was the Takeo branch office. It seems that three cucumber 4th gen members and 2 tomato 3rd gen members are aiming to become independent as producers after completing the two-year training period. The trainees are in their 20s and 40s and are planning to start farming in Takeo City, Ureshino City Shiota Town, Kohoku Town, and Tara Town. During the period, it seems that he learned through hands-on training at the farm, classroom lectures, and advanced site inspections under the guidance of a full-time lecturer. In the mock training, you will experience how to deal with various problems that you actually face, such as poor growth due to bad weather, and challenge new businesses. JA Saga (administrative 8 cities and 8 towns: Saga city, Tosu city, Taku city, Takeo city, Kashima city, Ogi city, Ureshino city, Kanzaki city, Yoshinogari town, Kiyama town, Kamimine town, Miyaki town, The topography of Omachi Town, Kohoku Town, Shiroishi Town, and Tara Town) can be roughly divided into three areas out of the topography of Saga Prefecture (5 areas). The Saga Flat Area, which occupies the southern part of the prefecture, constitutes the Tsukushi Plain and the Saga Plain, and the land is a fertile and highly productive grain area. Tianshan (1046.2 m) in the northern part of the prefecture / The foot of Mt. In addition, the Mt. Taradake area, which straddles the border of Nagasaki Prefecture, has developed fan-shaped plateaus, paddy fields between the plateaus, upland fields on the plateaus, and many gentle slopes, making it a production center for mandarin oranges. Taking advantage of these natural environments and location conditions, a wide range of agriculture such as vegetables, fruit trees, and livestock will be carried out, centering on land-use agriculture of rice, wheat, and soybeans, and will be returned to us and consumers. I would like to briefly explain the main groups and cities of the Midori district, surrounded by abundant nature and the blessings of the earth. “Kishima District, Saga Prefecture”, Omachi Town is located in the center of the prefecture, bordering Kohoku Town in the east, Takeo City in the west, Shiroishi Town in the south, and Taku City in the north. Saga Prefecture’s main road, National Highway No. 34, runs slightly south of the center of the town, and the Sasebo Line of JR Kyushu runs in parallel with it, and Omachi Station is in the center. Very blessed with transportation location. It is 25 minutes by car to the prefectural city of Saga, 15 minutes to the wide-area living area and central city of Takeo, and 1 hour to Fukuoka, the core city of Kyushu, by using the expressway. Therefore, it is in a very convenient position for commuting to work or school. The total area is as small as 11.50 km2. It has a shape close to a rhombus with 4.46 km east-west and 4.25 km north-south. As for the terrain, National Highway No. 34 and the JR Sasebo Line run from east to west in the central part of the town, and the northern part forms the foot of a mountain with a gentle south slope, and the top is the symbol of the town, Mt. Hijiri (elevation 416 m) and a series of mountains. Is running. The north side of National Highway No. 34 forms a dense urban area, and after that, many beautiful ponds are scattered on the gentle slopes of the hinterland, forming orchards and fields. On the other hand, the southern part is a contrasting flat land dotted with agricultural settlements, and most of them are regularly arranged paddy fields, which form a part of the Saga Plain in the breadbasket. The Rokkaku River meanders to the south and flows gently, forming a border with neighboring local governments. The streets of Omachi are a collection of shops that extend the heyday of the old coal mine era, forming a central city area, but in order to revitalize the shopping street, it is essential to improve access roads and parking lots. It seems that it is thought. In addition, in order to revitalize the industry, it is necessary to support entrepreneurs such as responding to advanced information technology and developing new products for the promotion of creative industries that respond to the new era, and people who work for it, especially I hear that you are trying to supply housing and residential areas for young people. The town is formed by a flat agricultural area that forms part of the Shiraishi breadbasket in the southern part of National Highway No. 34, and has a warm climate and fertile soil. It consists of complex management such as house horticulture and poultry farming, but in the future, we will strive to promote agriculture and forestry, develop special products and establish a sales system and support it toward the creation of a community where farmers can engage in lively agriculture. That’s it. Tachibana Town is located in the southern part of Takeo City, and is surrounded by low mountains in the east and west, with the largest paddy fields in Takeo City centered on the upper Shiomi River basin of the Rokkaku River. Tachibana Town is a historical place that has been open since the Yayoi period, as can be seen in the ancient tombs and archaeological sites of the Shiomi River scattered around the foot of Mt. Kishima Shiomi River. Among them, at the Tamashima Kofun, Otsubo Shingoishi, Miyako Ruins, Shakaji Ruins, etc., castles, bronze swords, bronze mirrors, dwellings, old living utensils, etc. were excavated, and the high cultural style of the time was retained. It can be extended. In the Middle Ages, it was also a transportation hub on the Nagasaki Highway, and even from the power of Mr. Tachibana, who prospered around Nagashima sho（village）, it is a town that has been open for a long time. The town has prospered as a pure farming village with agriculture as its main industry. However, due to social changes and the opening of high-speed cars that cross the center of the town, it has changed to a modern aspect. In recent years, maintenance has progressed, and along with mechanization and labor saving, modernization of agriculture incorporating poultry farming, livestock farming, and fruit trees is being pursued. On the other hand, it seems that the number of homes going to work is increasing. The townspeople are simple, most of them are indigenous and have a strong sense of hometown, and not to mention the residents of the school district, people who are active away from their hometowns are also supported and cooperated both physically and mentally by their enthusiasm and love for their hometowns and schools. I heard that there is a spirit of generosity. “Kashima City”, From the Gisuke flat cave (Furueda), earthenware such as streak and stamped patterns, which are said to be from the early Jomon period, have been excavated, and people have already lived in a part of the foot of Mt. Tara for thousands of years. I know that. During the Yayoi period, relics were distributed in alluvial fans such as the Kashima, Nakagawa, Hamakawa, and Shichiura coasts, and it is speculated that the Yayoi people were fishermen who lived on fish and shellfish from the Ariake Sea. The place name of Kashima first appeared in the history book in the book “Engi-shiki” (927), which says “Hizen Province Kashima 馬 maki”, and it is presumed that it played the role of the station building at that time. In addition, it seems that most of the current Kashima city belonged to “Nomi Township” in Fujitsu District, which is located in “Hizen no Kuni Fudoki”. Since the Middle Ages, Mr. Omura, who is based in Furueda, has been in power in this area, but in the Warring States period, he became a sphere of influence of Mr. Arima. In the early modern period, the administration was transferred to Mr. Nabeshima under the rule of Mr. Ryuzoji. The Kashima branch domain began in 1609, about 400 years ago, when the first feudal lord, Tadashige Nabeshima-Ko, was allowed to know in Fujitsu District, and has ruled the land of Kashima for 13 generations. After the Meiji era, local autonomy as a subordinate organization of the central government began, and there is a history of rapid consolidation and abolition due to the county system and town / village system. In modern times, the Kashima Municipal System was established by the merger of the five towns and villages of Kashima Town, Nogomi Village, Furueda Village, Hamamachi, and Kashima Village on April 1, 1954, according to the 1953 “Municipal Merger Promotion Law”. It started. On March 1, 1955, the then seven ura villages (excluding Ifuku) merged, and the current Kashima city was established. The city is located in the southwestern part of the prefecture, with the Ariake Sea spreading to the east and the Mt. Taradake mountain range to the west, and is blessed with a natural environment. According to the 2015 census, the number of households is about 10,000 and the population is about 30,000. As for the transportation system, National Highway No. 207 runs in parallel with the Nagasaki Main Line, and the JR Nagasaki Main Line is about an hour away from Fukuoka City and Nagasaki City. In the city, valuable historical townscapes remain nationwide in the Hama district and Omuragata district of Furueda, but these precious townscapes are gradually breaking down or disappearing and cannot be maintained by individual power alone. It’s done. It is said that it is planning to preserve this important historical heritage until the age of children and grandchildren, and to utilize it for creating an image of the city and tourism resources to promote the city and Hizenhama inn. On April 21, 2006, the two districts in Hizenhama inn were simultaneously selected as the “Important Traditional Buildings Preservation District (Important Preservation District)” by the national government (Agency for Cultural Affairs), and Kashima City is proud of its nationwide. It has been certified as a valuable historical heritage. This area is a post town for repatriation of Tara on the Nagasaki Highway, and it seems that the brewing industry and the fishery processing industry prospered as a port town facing the Ariake Sea. “Tara Town Fujitsu District”, The town is located in the southwestern part of Saga Prefecture, facing the Ariake Sea in the east, bordering Omura City in Nagasaki Prefecture in the west, Isahaya City in the south, and Kashima City in the north. The total area is 74.30 km2, 12 km east-west, and 12 km north-south. According to the Hizen Fudoki, when Emperor Keiko went to this place, he was said to be ”a small quadmo, a food helicopter”. It is said that it has become a “town of swords”. In 1953, the town administration was established and Tara Village was changed to Tara Town, and in 1955 it merged with Oura Village to become Tara Town. In March, Oaza Ifuku, a part of Shichiura Village in Kashima City, was incorporated and has been nurtured with a rich emotion. The area around 123ha, the symbol of the town, was designated as the “Saga Prefecture Natural Environment Conservation Area” on October 31, 2002. This is the second case after the Kashibaru Marsh in Nanayama Village. This was designated by Saga Prefecture for the purpose of nature conservation in the area of Mt. Tara, which is a treasure trove of rare animals and plants. Since 1993, the town has been pursuing conservation by sequentially purchasing natural forests around Mt. Tara and forests around Mt. Kyogatake, but with this designation, 22 species of plants such as B. amabile and P. tripteron, Japanese In principle, the collection and capture of five species of animals such as dormouse and Hynobius naevius was prohibited, and the prefecture’s permission was required for building construction and logging. As a result, the green property of Tara Town will be preserved in the future. A treasure trove of rare flora and fauna, Mt. Tara, which moisturizes people as a green dam in Tara Town, and many hikers are visiting to enjoy its rich nature. “Ureshino City”, The city is located in the southwestern part of the prefecture and was established in 2006 as Ureshino City by the merger of former Ureshino Town and former Shiota Town. Ureshino Onsen in Ureshino Town is one of the largest hot spring towns in West Kyushu, famous for its tea, hot springs, and ceramics. Many inns and hotels are lined up around the Ureshino River, and the hot spring is selected as one of Kyushu’s most famous hot springs, “Japan’s Three Great Skin Hot Springs,” which has a hot spring source with abundant hot water. Also, “Ureshi no Onsen boiled tofu”, which uses hot spring water, is very famous. Shiota Town prospered as a Shiota inn on the Nagasaki Highway (Sugar Road) and as a port of the Shiota River, and the old townscape remains. Is certified as a Japanese heritage site. Shiotazu is a historical and cultural area where you can see the two sides of “Kawaminato Shiotatsu” and “Nagasaki Highway Shiota inn” where the water transportation of the Shiota River due to the large ebb and flow of the Ariake Sea and the land route of the Nagasaki Highway intersected. It’s a town. Shiotatsu, which was selected as an “Important Traditional Buildings Preservation District” in 2005, has undergone repairs and landscape repairs to preserve the old townscape, and has been damaged by fire and storms and floods with the architectural style established in the Edo period. The heavy townscape lined with large townhouses “Iguraya” covered with strong white plaster form an emotion and landscape. The Shida area began producing ceramics around 1700, and under the name “Shida ware,” plates were mass-produced in five climbing kilns and sold nationwide during the heyday of the late Tokugawa period. In the Meiji era, they began to make products for overseas markets, and Shidashonosato, which was shipped from Shiodatsu, was shipped to various places. Ureshino Green Tea: It is said that the tea was cultivated in earnest in 1191 when Eisai Zenshi sown the seeds brought back from Song Kingdom (China) on the hillside of Yoshinogari Town, Saga Prefecture. The history of tea begins in 1440 when it was cultivated for private use in Kamifudo Saraya Valley, Ureshino Town, by a Chinese immigrant from mainland China. It is said that Reimin KO, a potter who came from Ming in 1504, brought in a Nanjing kettle and taught him how to make kamairi green tea. In Saga Prefecture, the cultivation of house oranges began in 1973 in what is now Karatsu City, and now boasts the largest production in Japan. House oranges, which can be eaten in the summer, have a perfect balance of sweetness and acidity. The exceptional taste has made it a popular product among consumers. Citrus unshiu, which is normally cultivated in the open field, is harvested from autumn and reaches its peak during the year-end and New Year holidays. It is the practice of house mandarin oranges to reach fruit one or two pairs earlier than this time. It is cultivated in a house and the house is heated from around October. Mandarin oranges are grown during the winter and shipped to various parts of the country from April (late) to September. In order to produce high quality and delicious oranges, thorough cultivation management such as temperature and water control is required, and behind that, there is work day and night of the producer and dedicated efforts, and in the summer house. The temperature is high and the work in it seems to be unimaginable. Green House Satsuma mandarin oranges produced in Saga Prefecture, which is famous as a top brand representing Japan, has the highest production volume in Japan. It is preferably slightly flat, thin-skinned, dark orange and bears fruit. “Green House mandarin” is a Satsuma mandarin orange whose skin is green and only the fruits inside are ripe. It is juicy and has a good balance of sweetness and acidity, and you can enjoy a refreshing aroma. In addition, it seems that cultivation is carried out with less heating than house mandarin oranges. I’ve heard that this makes it possible to harvest one to two months earlier than those cultivated in the open field. “Green House Satsuma Mandarin” from Saga Prefecture is on sale from July to September, so please order early before the deadline.
It is a Citrus unshiu grown in a heated greenhouse. Ordinary open-air oranges seem to line up in stores from early autumn to March. Greenhouse mandarin oranges produced in Saga prefecture are worth cultivating with great care, and consumers can enjoy them from April to October. By starting to heat the inside of the greenhouse from autumn, it makes us think that spring has come and promotes the flowering of Satsuma mandarin. At the greenhouse, which began heating in mid-October, the flowers are in full bloom in mid-November, and harvesting begins in late April. In addition, it seems that the influence of the weather can be reduced because it is cultivated in a situation that is half isolated from nature using a greenhouse. Therefore, not to mention the temperature, water and soil can be adjusted to good growth conditions for Satsuma mandarin. And, by adjusting the exquisite growing environment of the fruit tree farmers in this prefecture, it seems that beautiful, deep and delicious excellent fruits can be produced.
Greenhouse mandarin oranges that have been grown faster by heat-saving cultivation (consumes less soaring petroleum fuel), which has a lower heating temperature than ordinary house oranges. The bright green color has a refreshing sweet and sour taste, and the taste reminiscent of the countryside spreads throughout your mouth. In facility horticulture, there is a growing interest in energy conservation due to the recent rise in fuel costs. There is an urgent need to research materials that save energy by improving the thermal efficiency of heaters and improving the heat retention of green houses. However, at cultivation sites, it seems that there are many ways to reduce fuel costs by lowering the control temperature at night. It seems that lowering the control temperature at night slows down the growth rate of the plant, which may result in a decrease in yield. If the fuel cost has decreased but the yield has also decreased, it means that the fuel cost per yield has not changed, and as a result, energy saving has not been achieved. On the contrary, if the yield can be increased more than before by performing appropriate heating control when necessary, the fuel cost per yield will be smaller.
In Saga Prefecture, the cultivation of Greenhouse oranges began in 1973 in Karatsu City, which is now the city of Karatsu, and now boasts the largest production in Japan. Greenhouse oranges, which can be eaten in the summer, have a perfect balance of sweetness and acidity. The exceptional taste has made it a popular product among consumers. Citrus unshiu, which is normally cultivated in the open field, is harvested from autumn and reaches its peak during the year-end and New Year holidays. Greenhouse oranges will bear fruit earlier than this time. Cultivated in Greenhouse and warmed Greenhouse from around October. Mandarin oranges are grown during the winter and shipped to various parts of the country from late April to September. It is during this time that consumers are waiting.
This area is blessed with soils with different expressions, from the fertile land of the Saga Plain to the mountains and the Ariake coastal area. We have established a generous support system for new farmers who will be responsible for the irreplaceable future of regional agriculture. Among them, cucumber cultivation, which is well-known nationwide, is fully equipped with a training farm equipped with the latest environmental control technology. Also, in tomato cultivation, it seems that you can learn cultivation techniques using high wire cultivation by Venlo green house. High side wall structure of greenhouses: It seems that it is often expressed by the height of the pillars on the side. It refers to a greenhouse with a high height, and it is not a clearly defined structure but a general name. It is not clearly defined how many meters or more is called high eaves height, but at present, it seems that about 3.0 to 3.5 m or more is a guideline. It seems that if the roof shape is different, the size of the space under the roof and the height of the roof top will be significantly different even if the eave height is the same. Since the roof slope is large in a double-roofed greenhouse, the height of the building seems to be very high if the frontage is wide. On the other hand, in the Venlo type greenhouse, the roof slope is small and there are two small roofs for one frontage, so it seems that the building height is low even if the eave height is the same as the gassho double roof type. At the high eaves high facility, the upper space of the crop community is large, so it seems that sufficient space can be secured for using environmental control devices such as curtain devices, supplementary lamps, fine fog cooling, and circulation fans. A high eave height is advantageous for alleviating high temperatures in summer, and the shadows of members such as roofs and gutters are diffused, and it seems that unevenness in the light environment is reduced. In addition, since the volume of the cultivation space is large, the time change of the indoor environment becomes slow. The fuel consumption for heating is disadvantageous in a house with a small floor area because the ratio of the heat dissipation area increases when the eave height is high, but it seems that the difference in eave height almost disappears when the floor area is large. In Japan, until the early 1990s, the roof structure of glass greenhouses was mainly a gassho double-roof type with a wide frontage, and this type of high-elevation glass greenhouse was used for year-round cultivation of flowers.
