Kagoshima, which has many remote islands, takes advantage of the long topography of 600 kilometers from north to south to provide long-term supply from January to May every year. By the way, in the Nagashima and Amami districts, they are grown in red soil that contains a lot of minerals. New potatoes are in season from January after the new year. Starting with potatoes in early spring in Nagashima, Tokunoshima and Okinoerabu in the Amami area, followed by Tanegashima and Yakushima, then on to the mainland, Nejime, Kushikino, and back to Nagashima, heading north in a production area relay. In China, it refers to Ground nut, a member of the leguminous family. In 1808, Ranzan Ono, a herbalist, published a manuscript given to his disciples at the celebration of Ranzan’s 80th birthday. The subjects covered are Moutan peony, Wisteria brachybotrys, Western chrysanthemum, etc., and each of them is documented. In the postscript, his grandson Mototaka writes, “Ranzan has been healthy since his 60th birthday, and does not wear glasses. And that the number of disciples has reached 1,000.”), and after explaining that “Bareisho is a Potato”. It is suitable for the southwestern warm region, and was named after its high yield (high harvest). Famous as “New Potatoes” that are often shipped in spring.
【主な特徴】
As the security environment surrounding Japan becomes more severe, Tanegashima Island in Kagoshima Prefecture, known as the “land of firearms,” is facing a major move this year. It is Mage Island (area: 8.2 km2) where the government has purchased most of the land. Although it is located in Nishinoomote City, it is virtually an uninhabited island. It is expected that a runway will be built here and training for U.S. aircraft carrier-based aircraft will be conducted within a few years. A base for the Air Self-Defense Force will also be built. This runway has been long awaited by the U.S. military. Full-scale construction will start in 2022. In December 2021, the Ministry of Defense announced a layout plan for base-related facilities such as a vehicle maintenance shop. Most of the facilities are planned to be located in two towns in the central and southern part of Tanegashima, not in Nishinoomote City rice field. The Ministry of Defense explained that the peace and security of Japan are of great significance. In the event of a large-scale disaster, it will be possible to carry out relief activities in this area more accurately. All of the potatoes grown on Tanegashima are Nishiyutaka, and Cynthia potatoes are not grown according to a 2008 survey. Nishiyutaka potatoes were registered as Agriculture No. 23 in June 1978. On the other hand, Cynthia potato is Quimper, a breed developed by Germicopa of France in 1996, and later introduced by Kirin Brewery. It has a rounded shape and is most commonly grown in warm climates. When I say “new potatoes”, I mean Western Yutaka, which is cultivated nationwide. Cynthia is characterized by fair skin, round and elongated. Good quality for food and good appearance. In Tanegashima, it seems that potatoes are often grown after harvesting ocarina. Cultivation seems to be outdoor planting and multi-cultivation. It seems that one row is the standard for outdoor planting and two rows for black vinyl mulch. The reasons for using black vinyl seem to be that weeds do not grow and that growth can be expected by raising the soil temperature. Additional fertilization is required for outdoor planting. By the way, one of the characteristics of potato cultivation on Tanegashima is that there are very few pests and diseases compared to the mainland. Therefore, it is very popular as an ecological agricultural product because it requires almost no pesticides. After planting, you don’t have to do anything other than harvest, so it doesn’t take much time. However, potatoes also have a weak point, and it seems that they must be careful of frost when planting in autumn. Frost damages the leaves and greatly affects production. In addition, Nishiyutaka potatoes are a variety that is delicious when freshly dug and can be eaten in any way. Cynthia potatoes, on the other hand, seem to become tastier if left to rest for a certain period of time after being harvested. At the JA Taneyaku Kyuishido Collection and Shipping Center in Ishido, Nishinoomote City, the potatoes are sorted and packed in boxes before being shipped to the mainland by ferry. However, there is also damage from late frost until March every year, so we can’t let our guard down. Compared to sweet potatoes, it seems that caution is required against frost. Harvesting seems to be done by digging using a machine. After that, we put the potatoes in a small container and collect them. The fruits are then transported to the fruit sorting area of the agricultural cooperative. In 1970, at the Aino Potato Center of the Nagasaki Prefectural General Agriculture and Forestry Center, “Nishiyutaka Potato” was artificially crossed with “Dejima Potato” as the mother and the father “Choukei No. 65 Potato” (Saikai No. 15 Potato). In 1978, the variety was registered as “Potato Norin No. 23”. It is suitable for the southwestern warm region and excels in fertility. Cultivation and high harvest expected in spring and autumn.（Since the crops were swollen and the yield was high, the cultivation increased rapidly especially in spring mulching since 1985.）The flesh is pale yellow and moist. The leaf color’s dark green, which is slightly darker than “Dejima Potato”. The leaflets are a little thick inside and reach a little sparse. Plasmodium resistance major gene: Plague resistance major genes, bacterial disease of eggplant: To provide a bacterial wilt disease resistant inducer which contains a compound indicating resistant induction activity against a bacterial wilt disease as an effective component, and a bacterial wilt disease prevention method using the compound. Patent Office）, soft rot pathogen: To provide a mass production method of seed potato seedlings, capable of preventing rot and soft rot of a rooting zone to increase probability of survival, and mass-producing at one time nondisease seed potato seedlings capable of increasing percentage of rootage when planting. To provide a method for increasing tubers such as calla tubers or the likes, achieved in increasing tubers such as calla tubers or the likes in a warm area such as Japan or the like, by inhibiting generation of soft rot and activities of endotrophic mycorrhiza. Patent Office）And, Tuber rot And, it has moderate or higher resistance to tuber rot than ‘Mother: Dejima potato’. Weak to powdery potato common scab: spongospora subterranea. 16S rRNA gene of the causative strain（Prokaryote, gene sequence）Or from 16S rRNA gene, ITS region（Ribosomal DNA; rDNA; Eukaryote））Novel Primer Pairs for Amplifying Between and Methods for Detection and Identification of Potato Scab Pathogenic Strains Using Them,（NEW PRIMER PAIR FOR AMPLIFYING BETWEEN ITS REGIONS FROM 16SrRNA GENE OR 16SrRNA GENE OF POTATO SCAB-CAUSING STRAIN, AND METHOD FOR DETECTING AND IDENTIFYING POTATO SCAB-CAUSING STRAIN WITH THE NEW PRIMER PAIR-Patent Office）, Potato mop-top virus carries tuber brown ring spot. Regarding PMTV, there is a clear difference in tuber brown ring spot resistance among major potato cultivars. Somewhat weak resistance. However, the field resistance is quite strong. Since there’s little dehiscence of potatoes and little breakage of foliage due to the wind, it’s widely suitable for the second cropping area in western Japan. Agriculture in the Kumage region, which is located on the boundary between temperate and subtropical zones, has greatly different production conditions between Tanegashima and Yakushima. Sugarcane, sweet potato, leaf tobacco, milk, ponkan oranges, and tankan are crops that account for more than 10% of the prefecture’s agricultural output value, and Koshihikari rice and tea, which are shipped the fastest in Japan thanks to the warm climate, are produced here. It seems that they are also trying to change it. In addition, farmland irrigation facilities are being developed on both Tanegashima and Yakushima, and efforts are being made to develop new agricultural initiatives, as well as development of production and management bases, distribution bases, and rural life bases through national treasury (directly controlled) projects and prefectural single projects. It seems certain. Agriculture-related organizations include the Taneyaku Agricultural Cooperative Association (the Nishinoomote City Agricultural Cooperative, the Kagoshima Kumage Agricultural Cooperative, and the Yakushima Agricultural Cooperative merged on April 1, 2006) and the Kumage Agricultural Mutual Aid Association. July 7, 1995 to cope with the aging of agricultural workers and the shortage of agricultural successors
Japan, Nakatane Town, Minamitane Town, Kagoshima Kumage Agricultural Cooperative (currently Taneyaku Agricultural Cooperative) and Tanegashima Agricultural Public Corporation. Nishinoomote City Agricultural Control Center (reorganized into an incorporated association on September 20, 2001), and on September 25, 1996, Kamiyaku Town, Yaku Town, and Yakushima Agricultural Cooperative (now Taneyaku Agricultural Cooperative) each established the Yakushima Agricultural Control Center. Since Tanegashima is flat and has many upland fields, land-use type sugar cane, sweet potato, Complex management that combines livestock farming is prosperous, and some specialize in leaf tobacco, tea, etc. In addition, leather leaf fan of a fern plant (The feature is that the leaves are dark in color and last for a long time. It seems that the quality and freshness are highly evaluated by the market and consumers. It is popular as a foliage that is indispensable in flower arrangements. In Tanegashima, cultivation began in Minamitane Town around 1985, and now it is mainly cultivated in Nakatane Town and Minamitane Town, boasting the largest shipping volume in Japan. Tanegashima seems to be able to ship almost all year round. They can’t ship in the middle of winter, but they seem to be careful about frost. As a countermeasure against the frost, they come to the greenhouse early before dawn and sprinkle water. Frost management seems to be very difficult. Also, in early spring, prevention seems to be essential. I heard that if you neglect it even once, the leaves will be eaten away by pests. The cut leaves are soaked in water for sorting. There are five sizes, S, M, L, 2L, and 3L. , It is often used in flower arrangements, and is particularly in demand for gifts and weddings. Recently, it is used as a rug for small dishes at restaurants such as sushi restaurants. The smell of the fern and the appearance of the food are even more toned, and the harmony is wonderful. In addition, it seems that there are many imports from foreign countries. However, compared to domestic products, it seems that the shape is not good, the elasticity is bad, and it does not last long. The Leather Leaf Fan cultivated in Tanegashima seems to be a variety called ‘Mild’. The green leaves are beautiful, resilient, and seem to last a long time. It seems that the name comes from the luster of the leaves that feels like tanned leather. It is a very delicate plant, and the temperature conditions are around 20 degrees Celsius, and it prefers acidic soil.) is high.) is designated as the first Kagoshima brand production area in the prefecture for flowers. As for sweet potatoes for fruits and vegetables, Anno sweet potato seems to be growing in acreage in recent years due to its sweetness. Agriculture on Yakushima has many sloping lands, and the arable land rate is low at about 2%, so it is scattered in belts along the coast. It seems that they are managing mainly Citrus reticulata and Tankan mandarin by making use of the arable land. Tankan mandarin is designated as a Kagoshima brand production area. “Kagoshima Brand: Tankan Orange: Safe and Secure, Prefectural Certification Registration Number 205016” has been designated as a prefectural brand (Minamisatsuma: May 29, 2009), forming a major production area. Kagoshima produces more than 70% of the national production. In 1906, saplings and seeds were introduced from Taiwan, and they have been spread and cultivated in regions such as “Amami Oshima”, “Yakushima” and “Tanegashima”, which are warm and suitable for growing subtropical citrus. On the mainland, cultivation in the frost-free area in the southern part of the prefecture is popular. In addition, the unique balance of sugar and sourness and refreshing aroma are highly appreciated by consumers. “Ponkan Orange” × “Navel Orange” is said to be a citrus fruit of natural crossing seedlings, and is a kind of tangor. The outer skin is slightly thicker than that of a mandarin orange, and the surface is a little rugged. The Taneyaku region is located in the south of Kagoshima Prefecture and is known for having the largest rocket launch site in Japan. Tanegashima, the island closest to the universe, and Mt. Miyanoura, the highest peak in Kyushu, rise majestically. The main areas are Yakushima, a World Natural Heritage Site (registered in 1993) and Kuchinoerabujima. JA has an island of cutting-edge science and an island registered as a World Heritage Site within its jurisdiction. “Yakushima” is home to many endemic species and endangered plants and animals, including the globally unique Yakusugi (an evergreen coniferous tree that belongs to the cedar family and is endemic to Japan), which is thousands of years old. It is an area with unique ecosystems and excellent natural scenery, such as the typical vertical distribution of vegetation from the coastal area to the vicinity of the central mountaintop. Tanegashima is the closest to the Osumi and Satsuma peninsulas among the Nansei Islands, which are scattered to the south of Kyushu, and is the third largest island after Amami Oshima and Yakushima. It consists of one city and two towns, Nishinoomote City, Nakatane Town, and Minamitane Town, and its highest point is only 282 m, which is a contrasting island compared to the neighboring Yakushima Island, which is 1,936 m above sea level. Agriculture such as sugar cane, sweet potato, and early paddy rice cultivation is the key industry in the temperate climate. Tanegashima was formerly known as Tane no Shima, and during the Nara period, the only Nationalist government on the South Island was established, and it was located within or around the area, and along with the national government office there was the country’s largest building, Kokubunji. During the Muromachi period, the Tanegashima clan ruled this area. It has a historical origin as an island with the introduction of guns, and at the same time it is an island where history and future coexist because there is a space center that brings together the best of Japanese science and technology. Recently, it seems to be popular as a surfing spot. In addition, the Hirota ruins（A mass grave from the end of the Yayoi period to the 7th century. Buried in the cemetery are people dressed in shell accessories.）were designated as a national historic site (March 2008), and the shrine ritual held with the first two months of the year to forecast (or pray for) a successful harvest at Homan Shrine was designated as a national important intangible cultural asset. It is rich in tangible and intangible cultural assets such as historic sites, folk songs, local performing arts, annual events, etc., including designation (March 2016). It is located about 115 km south of Kagoshima City and has an area of 445.05 km2. Tanegashima is famous as the place where guns（In Japan it was introduced at Tanega-shima Island in 1543 and thus it was called a Tanegashima rifle or simply Tanegashima. Matchlock guns (also called Tanega-shima Island) were imitations of Portuguese guns. The book is based on the account given by Hisatoki TANEGASHIMA, a local lord, concerning the historical fact of the transmission of guns (specifically, arquebuses) to Japan on Tanegashima island during the Sengoku Period (Period of Warring States), describing how Hisatoki’s father Tokitaka TANEGASHIMA had acquired guns and established his gun manufacturing process; this account was edited by the abbot of Satsuma Province’s Dairyuji Temple, Bunshi Nanpo.）were introduced. The industry is mainly agriculture, and the best in Japan is active in cultivating early Koshihikari rice, sugar cane, tea, etc. In the fishing industry, there are abundant fresh seafood such as Sulculus aquatilis, spiny lobster, and squid. The constituent cities and towns all formed a friendship city tie-up with Sakai City in Osaka Prefecture on October 18, 1986. Located in the north, the north-south length is 25.2 km, the east-west width is 8.2 km, and the circumference is 63 km. The east, west and north face the sea, and the south borders Nakatane Town. The area is 205.66 km2 and occupies about 45% of Tanegashima. The geology belongs to the Cenozoic Paleogene Kumage Group, which spreads throughout Tanegashima, and diluvial uplands develop everywhere. Conglomerate, shale, and igneous rock are found in some places, and the eastern hills contain the lignite layer. The soil is mainly light brown clay and andosols. Floating on the sea 12 km west of the city, Mage Island has an area of 8.17 km2 and a very low flat of 71.7 m at the highest point. The average annual temperature of the city is 19.5 degrees Celsius, which is extremely warm. From May to October, the average monthly temperature exceeds 20 degrees Celsius. The midsummer sunshine is strong, but the pleasant sea breeze is always blowing, and the daytime heat is as cool as the mainland of Kyushu. On the other hand, winter temperatures range from 10 to 14 degrees Celsius, rarely below 0 degrees Celsius at least in the day. The annual rainfall is around 2,000 mm, and the period from March to September tends to be relatively heavy. Although it has a subtropical climate close to a warm climate, it is a typhoon-prone area that can be said to be fateful. The land of Anno that became known all over Japan by producing Anno potatoes. Tennyogakura (238 m above sea level) is a mountain that looks like it’s rising from a green carpet. In the old days, it was called “Amamegakure” or “Amamegakura”. Legend has it that “Nioh（two Deva Kings）” stopped by on his way south with the rocks of Misaki on the country and took a rest because of the good view. Because of that, when I stood up, my backpack was cut off creeping plant（chasuble）, leaving the rocks alone. Even now, there is a shrine under a large rock near the summit, which I watch over. There used to be tennin shinto music shrine, but it seems that it was moved to the current Anno Shrine in 1929. There is a legend that the deity devoted shinto music because he liked dancing. The appearance of a combination of rocks about 2 room at intervals (about 3.6 m) in length is a sight to see. Nationally designated cultural property（Natural monument）: 赤髭（Larvivora komadori (Temminck, 1835）, 昭和45年1月23日, 烏鳩（Columba janthina Temminck, 1830: 準絶滅危惧 (減少) Encyclopedia of Life）, 昭和46年5月19日, 陸寄居虫（Coenobita cavipes）, 昭和45年11月12日. Country-selected cultural property: Nishinoomote’s Tane scissors manufacturing technology (folk technology), Intangible folk cultural property that should be documented, March 8, 2012, Tane scissors manufacturing technology preservation society, etc. Designated by the city, Registered and Selected Cultural Properties As of March 1, 2020, a total of 75 properties have been confirmed (3 nationally designated, 3 nationally registered, 3 nationally designated, 10 prefecturally designated, 56 city designated.
The subcommittee is united in its efforts to acquire certification from Kagoshima Prefecture and reduce the use of pesticides to less than 50% of the prefectural standard for environmentally friendly cultivation. It seems that pesticides are only sprayed at the time of seed disinfection and plague outbreak. In addition, we are making soil mainly with organic fertilizer. Since the soil fertility is low, it seems that soil diagnosis is performed and an appropriate amount of fertilizer is applied.
