In fiscal 2021, the national food self-sufficiency rate was less than 40% on a calorie basis, but in Yachiyo Town it seems to be over 100%. Many people are aware of the splendor of agriculture in the town, and activities such as SGDs（持続可能な開発目標）are also active throughout the country.
The Yachiyo District Management Study Group is a study group consisting of 18 members with the aim of trying more advanced initiatives within the JA Joso Hikari Yachiyo District Horticulture Club. The functional variety “Orange Quinn Chinese Cabbage”, which has been shipped since 2017, about five years ago, has extremely high quality and seems to be highly evaluated by the market. As you probably know well, the JA Joso Hikari Yachiyo area is an outdoor vegetable production area centered on Chinese cabbage, lettuce, and melons. Chinese cabbage, in particular, boasts one of the largest shipments in Japan, with 2 million cases per year. The management study group, which is the producer of these items, seems to have been organized in 2011. Every year, the study group conducts training in advanced areas to increase knowledge, and as a challenge to improve management, it seems that new items have been examined and cultivation has begun. This excellent agricultural product cultivated by the research group contains cis-lycopene, which can be expected to have an antioxidant effect, and carotene, which can be expected to have an immunity effect. In addition, it seems that it is easy to cause leaf tips to die, and that the cultivation characteristics are different from Chinese cabbage, which is usually cultivated, so it was known that the quality is likely to vary. Therefore, in addition to conducting soil diagnosis at the production area and designing fertilization including soil nitrogen, it seems that they have carefully held seminars and field trips to understand the characteristics of the variety. As a result of these efforts, the quality of the research society is Orange Quinn Chinese Cabbage has been highly evaluated by the market, and it seems that it is selling more favorably than the normal white varieties. Furthermore, the research group will continue to improve the technology and will continue to search for new shining items that will please consumers. Yachiyo Town, Yuki District, located in the southwestern part of Ibaraki Prefecture, is the prefecture’s largest producer of Chinese cabbage and is characterized by flat fields that stretch on forever. It seems that Chinese cabbage has been cultivated in this area since the Taisho period. In the Showa era, the start of shipping to Tokyo following the establishment of a gardening association and the introduction of new cultivation techniques to save labor seem to have triggered the scale expansion. After that, in 1966, it became a designated production area, and planned shipments and subsidies for pest control equipment began to be implemented. Orange Quinn Chinese cabbage, which is also synonymous with orange Chinese cabbage, is a breed that was created by crossing Chinese cabbage and European turnip. It is a Naka-Wase cultivar characterized by a bright orange color on the inner part, and it seems to be harvested from autumn within the year in warmer regions, and in autumn in cooler regions. This excellent agricultural product is a registered trademark of Takii Seed Co., Ltd., and was launched in 1990. It is an epoch-making Chinese cabbage that was created through the fusion of biotechnology and breeding technology at the time. The outer leaves are green like regular Chinese cabbage, but the inner leaves are orange. The impression is that it has a strong sweetness and a good crispness, and there is little peculiar grassy smell. The orange core leaves seem to contain cis-lycopene, which is not contained in common Chinese cabbage. C40H56 (5,9-cis-lycopene) seems to have the property of being more easily absorbed into the body than normal lycopene. In addition, a wide range of Plasmodiophora brassicae Woronin (Ago, Kasama City, Ibaraki Prefecture) is a soil and water-borne disease caused by a type of filamentous fungus. In addition to Chinese cabbage, it occurs in cruciferous plants such as cabbage and broccoli. When infected with this disease, the growth of stems and leaves declines, and the leaves and stems wither and turn pale yellow. When plants are pulled out, bumps appear on the roots. The size of the bumps varies from small to large, ranging from about 1 cm in diameter, to almost all of the roots. , It occurs frequently in fields where cruciferous vegetables are continuously cultivated. This pathogen grows at 9-30°C, but it seems to be most likely to be affected at around 18-25°C. Avoid continuous cropping of cruciferous vegetables and gramineous plants. Crops and crop rotation Correction of acid soil with lime and drainage measures Introduction of resistant varieties In the nursery and fields planned for planting, soil disinfection Sampling and disposing of diseased strains and formation of bumps It seems that it is good not to leave the roots in the field.) In addition, cislycopene is a pigment component contained in orange-yellow tomatoes, and can be expected to have the same effect as C40H56 contained in red tomatoes. Lycopene intake induces colonic regulatory T cells in mice and suppresses food allergy symptoms (Lycopene intake induces colonic regulatory T cells in mice and suppresses food allergy symptoms), Jumonji Gakuen Women’s University A research group led by Chihiro Ushiroda, Assistant Professor, Department of Food Development, Tomohisa Takagi, Associate Professor, Graduate School of Medicine, Kyoto Prefectural University of Medicine Graduate School of Medicine, Associate Professor, Tomohisa Takagi, and Yuji Naito, Professor, Department of Bioimmunonutrition, Allergy model mouse A research paper on this topic was published in the scientific journal “Pediatric Allergy and Immunology” on November 16, 2021). I have a report. The major carotenoids of Chinese cabbage are β-carotene and lutein, while the major carotenoids of orange Chinese cabbage are prolycopene, β-carotene and phytoene. The amount of total carotenoids and polyphenols is higher than that of normal Chinese cabbage, and it seems to have a strong antioxidant capacity. Isomer of Lycopene-Prolycopene. Lycopene is known to be the major carotenoid in tomatoes and has a strong antioxidant capacity. Two between intramolecular C. It is also called all-trans-lycopene because all the double bonds are trans-type. As an isomer of lycopene, there is pro-lycopene, which has a cis-type double bond in the molecule and is also called “cis-lycopene.” It has been reported that when both are ingested as food, cis-lycopene has a higher absorption rate. Anticipating even greater health benefits. The pigment composition of orange Chinese cabbage and Antioxidant capacity: Chinese cabbage in general contains carotenoid pigments such as beta-carotene and lutein found in green vegetables. On the other hand, orange Chinese cabbage contains the highest amount of prolycopene. To date, there have been no reports of Chinese cabbage containing prolycopene. In plant carotenoid synthesis, pro-lycopene (partially cis-type) is converted to lycopene (all-trans-type) by enzymes, and β-carotene is further synthesized. However, it is presumed that trans-lycopene is not synthesized in the inner layer of orange Chinese cabbage because the conversion enzyme does not function. Orange Chinese cabbage and Chinese cabbage superoxide active. As a result of comparing the oxygen scavenging ability (SOD-like activity), orange Chinese cabbage is stronger. Plant pigments add color to food and are expected to have various health functions. In the future, it seems necessary to clarify the specific in vivo functions of foods containing prolycopene. In Yachiyo Town, Okoku Kameda (1807-1881: from Shimousa Okada County (now Ibaraki Prefecture), a scholar of Chinese classics who was active at the end of the Edo period. Ryorai Kameda (1778-1835: Born in Edo. Eldest son of Hosai. His name was Nagazusa. Confucian scholar of eclectic studies who served as a Confucian vassal of the Shimousa-Sekiyado clan. He is also known as a calligrapher. He entered the school and studied Chinese studies and poetry, married Nui, Ryorai’s adopted daughter, inherited the master’s family, and inherited the family studies. Became a Confucian vassal of the Shimousa-Sekiyado domain (now Chiba prefecture) and taught at the domain school Kyorinkan. After the Meiji Restoration, Tokyo. He opened a private school in Fukagawa, and was engaged in giving lectures.), so there is a monument related to Okoku, as well as Sazan Nakajima, Hanko Akamatsu, Sekiseiken, Shoyo Yokoshima, and Kinsai Suzuki. Excellent Chinese scholars left stone monuments. It seems that the contents are wide-ranging, such as educators, religious people, terakoya, patriots at the end of the Tokugawa shogunate, devastated land restoration service, tea industry service, and war dead. In addition, Mr. Kitano, who devotes himself to cultivation every day at Minokuchi introduced this time, also contributes to local agriculture. We also focus on educating young people who will succeed us. “Yachiyo Town, Yuki District”, Jomon pottery, stone tools, and dwelling traces have been found in archaeological sites such as Kuriyama, Ozaki, and Niedo. During the Nara Period, the Kinugawa River, which had been winding around the west side of the Kawanishi District, was renovated to form the current Kinugawa River. In the Heian Period, iron making was carried out at Ozaki Maeyama, farm tools and weapons were made, and a samurai corps was formed. It was around this time that the Taira no Masakado turmoil occurred, and even in Yachiyo Town, Kuriyama, Ashigaya, Hiratsuka, etc. are treated as battlefields. At the end of the Warring States period, the eastern half of the town, including Sugenoya, Waka, and Ozaki, was under the control of Mr. Tagaya, and from the north to the west was under the control of Mr. Yuki. In the Edo Period, due to the change of lords, the Yachiyo area came to have a complicated control of Mibu territory, Koga territory, imperial fief, Hatamoto domain and so on. In the Kyoho period（1716-1736）in the middle of the Edo Period, Iinuma and Yamakawa Swamp will be reclaimed and Yoshida irrigation will be completed. After the abolition of the feudal clan after the Meiji Restoration, the municipality system was enforced in 1889, and the old villages of Anjo, Shimoyuki, Nakayuki, Nishitoyoda, and Kawanishi were born, establishing the foundation of the autonomy system. After that, with the aim of expanding the transportation economic zone and strengthening local administration and finance with the rapid growth after the war, in 1955, the former five villages and Sanwa village Narita merged to form Yachiyo village. With the enforcement of the town system in 1972, it became Yachiyo Town. It is located in the center of the Kanto Plain, southwest of Ibaraki Prefecture, about 60 km to the capital Tokyo, about 70 km to the capital city of Mito, and about 20 km to Tsukuba, a city where science and technology are concentrated. It is adjacent to Shimotsuma City across the Kinugawa River in the east, Koga City in the west, Yuki City in the north, Joso City and Bando City in the south, and National Highway No. 125 runs east to west in the center of the town. The terrain is 7.7 km east-west, 12.4 km north-south, and the total area is 58.99 km2. The terrain is generally flat, with paddy fields open in the eastern part and upland fields in the western part, with the mountain river flowing through the central part of the town as the boundary, and a small amount of flatland forest remains. Wide area above sea level (eastern end) 139 ° 51′ (West end) 139 ° 57′(South end) 36 ° 07′ (North end) 36 ° 14’58.99 km2 (East and West) 7.7 km (North and South) 12.4 km (Maximum) 29.8 m (Minimum) 18.7 m. Regarding the weather, the average annual temperature is around 14 ℃, and the annual rainfall is around 1,250 mm. In winter, the northwest monsoon blows, but the amount of snowfall is extremely small and the climate is warm. Taking advantage of the flat and fertile land, warm climate, and location conditions near the capital, agriculture is regarded as the core industry, and mainly vegetables, rice cultivation, fruit trees, livestock, and other suburban agriculture are being developed, and the main areas of the metropolitan area. Famous as a food production base. In addition, it is one of the leading horticultural production areas in the prefecture, and among them, Chinese cabbage boasts the largest production volume in Japan, and net-based melons are also cultivated, and pears have been designated as a brand production area（1992年; Akuto Pear）in the prefecture. The town boasts one of the largest melon production in the country, and when the time comes, the scent of sweet melon overflows throughout the town. In recent years, in addition to outdoor cultivation, we have also adopted house cultivation to make sweet and delicious melons. From May to June, many varieties such as Prince, Kinsho, Homerun, Takami, and Quincy are cultivated as spring melons. Among them, Takami Melon, which is the most produced in the town, is a large ball, juicy and has a high sugar content, has a long-lasting meat quality, and is often used as a souvenir and is appreciated. From September to October, Earl’s melon is cultivated as an autumn-suppressing melon. Earl’s melon is cultivated with strict control of temperature, humidity, water, etc., and only one fruit is produced per plant, giving it a rare and luxurious texture with a smooth texture. As the name Akuto Pear suggests, it grew up in the sober land of the Kinugawa River, bathed in the pure sunlight. Kosui Pear is cultivated in August, Hosui Pear in September, Akizuki Pear in October, and Niitaka Pear. Yachiyo Chinese cabbage is a hot pot dish that is often eaten in the cold season, and is a supporting role of the hot pot. The town boasts the highest production in Japan, producing autumn-winter Chinese cabbage and spring Chinese cabbage, and harvesting and shipping peaks from late October to mid-June. Autumn-winter Chinese cabbage has a softer fiber when exposed to frost, and the sugar content of the leaves increases, so the sweetness also increases. Spring Chinese cabbage is characterized by its freshness and fluffiness. Vitamin C is not lost even when salted, and good intestinal bacteria such as lactic acid bacteria are produced, so there are great expectations for an intestinal regulation effect. In addition to melons, pears and Chinese cabbage, the town produces a lot of delicious vegetables throughout the four seasons. In addition, because it is flat and has good water access, rice cultivation is also popular, and the far-reaching golden countryside occupies about 40% of the total crop harvest area. Chinese cabbage pickled in kimchi, which uses the highest production of Chinese cabbage in Japan, countryside miso, which uses locally produced soybeans, and rich, handmade natural brewed soy sauce that takes advantage of the blessed climate and water quality, have gained popularity for consumption. In addition, there are many flavors of hometown such as handmade dried natto and chewy udon, which gives a simple taste. 県指定建造物 : 佛性寺観音堂 / 仁王門（附観音堂宮殿1基 / 棟札1枚）, 2棟, 栗山, 佛性寺, 平29.12.25, 県指定彫刻 : 木心乾漆如来形坐像（付乾漆断片64片）, 1躯, 栗山, 仏性寺, 昭57.3.4, 県指定彫刻 : 木造十一面観音立像, 1躯, 大字八町, 新長谷寺. 八千代町教育委員会, 株式会社地域文化財コンサルタント 2009 “菱毛道西遺跡（大字平塚）” 八千代町埋蔵文化財調査報告書13 : 株式会社エフピコ工場建設に伴う遺跡の発掘調査, 工場建設, 集落, 古墳時代, 竪穴住居跡, 土師器: 坏, 甕他, 須恵器: 坏, 甕他, 石製品: 紡錘車他, 土製品: 土玉, 土錘他, 集落, 平安時代, 竪穴住居跡, 土師器: 坏, 甕他, 須恵器: 坏, 甕他, 灰釉陶器: 高台坏埦, 鉄製品: 釘他, 瓦片, 羽口. The “Yachiyo Fall Festival” (sponsored by the Yachiyo Town Festival Planning and Management Committee) was held on November 12th and 13th, 2022 at the Sugenoya Town General Gymnasium in the same town, attracting many families and children. At the outdoor stage on the first day, the comedian and musician Hanawa performed a new song with lyrics that express the characteristics of the town, and it seemed to have a lively atmosphere. The festival will be held for the first time in three years due to the effects of the corona crisis. In addition to performing arts presentations, calligraphy, photographs, picture letters, bonsai, and other works, it seems that the kitchen car introduced by the town sold chankonabe dishes supervised by the Grand Sumo wrestler Nishonoseki stable.
It does not have the grassy smell peculiar to Chinese cabbage, and it has a pleasant crisp texture. The core leaves of oranges have a sweet taste and are said to be suitable for use in salads, as well as in pickles and stews. In addition, it is a mid-to-early maturing species with a bright orange inside color, and it is said to be ideal for autumn to year-round in intermediate and warm areas, and autumn in cool areas. Cis-lycopene-containing orange core leaves seem to contain cis-lycopene, which is not contained in common Chinese cabbage. Normal lycopene (a red natural pigment that has a strong antioxidant effect and prevents the oxidation of low-density lipoprotein cholesterol, so it is expected to be effective in improving blood flow and preventing lifestyle-related diseases) It seems to have the property of being easily absorbed by. As for the key point of cultivation, it seems desirable to use a slightly larger amount of fertilizer than the general medium-early maturing variety, promote growth from the early stage with the main basal fertilizer, and ensure that additional fertilizer is applied to maintain the fertilizing effect until the end.
