It seems that it has become clear that the hydroponic cultivation of melons carried out in Tsugaru City has a large difference in performance depending on the variety. This is the hydroponic cultivation of “Machida Silk Melon,” which was started at the glass house in Tsugaru City in Machida, Tokyo (in 2009, the Machida Chamber of Commerce and Industry started in collaboration with 10 cooperating companies in and outside Machida. For this purpose, local small and medium-sized enterprises can survive in the future by applying the technology possessed by regional cooperating companies such as manufacturers of precision machinery and medical equipment to the field of agriculture and creating high-value-added agricultural products. It seems that there was an urgent background to cultivate a business in a new field. In a situation where it can not be said that the conditions are favorable because there is no person who has experience in fruit cultivation specializing in melon, the related companies said, “High yield, low cost and high price. Under the slogan “Making quality melons”, we are focusing on developing a completely new type of cultivation system that has never been seen before by repeating trial and error. We utilized this system created by concentrating Machida’s technologies. The cultivation method is named “Machida formula New farming method”, and normally one to four plants are harvested, but the new farming method has made it possible to produce about 60 plants. It seems that the quality of high-grade melon has been reached and preparations are being made steadily for full-scale commercialization. And this epoch-making cultivation system itself will be utilized in the suburbs and other agricultural products in the future. It is expected to go. Machida Silk Melon, a name that subtly creates an elegant and fascinating atmosphere suitable for a beautiful light green color and a beautiful mesh pattern, was once a relay point for the Silk Road where Machida carried silk from Hachioji to Yokohama Port. It seems that it was named after it was there. This luxurious melon is full of smoothness and freshness that is reminiscent of high-quality silk products when actually eaten. It seems that there are many voices from the people concerned that once you try it, you will be captivated by its mellow scent and superb sweetness. Behind the creation of a new local agricultural brand, it seems that there is also the aim of promoting the revitalization of agriculture in Machida City and its surrounding areas in Tokyo, creating new local industries, and building a richer local community. Today’s Japanese agriculture is at stake amid economic globalization, with various problems such as shrinking agricultural land, aging agricultural workers and a shortage of successors, excessive food imports, and a decline in self-sufficiency. ing. In addition, given the reality that fallow land is increasing, it is extremely difficult to develop a new community-based agribusiness=high-value-added agriculture through agricultural-industry-commercial collaboration with a view to overcoming this situation. Seems to be a constructive attempt. Beyond this trend, it seems that there is an additional advantage that various secondary processed products can be created derivatively and new employment can be expected. The most distinctive feature of the hydroponic cultivation tank used in the new farming method seems to be the structure in which the liquid fertilizer flowing out from the center hits the inner wall of the tank and then drains from the four corners with convection. “Karman vortex” that promotes convection in the tank (when a columnar object moves at an appropriate speed in the fluid (the same even if the object is stationary and the fluid moves), vortices in opposite directions are generated alternately from both the left and right sides of the object. Karman vortex street is the world of fluid engineering and fluid machinery. When a columnar object such as a column or a prism is placed at right angles to the flow, the peeling shear layer from the object is perpendicular to the mainstream. As it vibrates and vortices of opposite signs are emitted in each cycle, a staggered array of vortices is formed downstream of the object. Karman (1911) is perpendicular to the distance in the mainstream direction of the vortex. It has this name because it theoretically shows that this vortex train is stable only when its ratio to the distance between directions has a certain value. In a cylinder, the Reynolds number Ud / νUd / ν (U). : Mainstream velocity, d: Cylindrical diameter, ν: Dynamic viscosity) seems to appear in a wide range of about 50 to 2 × 105. The frequency ff at which the vortex is emitted from the object is the representative length of the object (diameter d in the column). And the fd / Ufd / U, which is dimensionless at the mainstream velocity U, is called the vortex number and seems to be a function of the Reynolds number. Approximately 0.2 holds in the range) and fluctuations that help the absorption of nutrients from the roots occur. It seems that the health of the roots can be maintained because the roots grow radially in the ideal direction and the liquid does not stagnate.) Hydroponics of melon seems to be in the sixth crop now. It seems that five varieties have been cultivated so far in the demonstration test that started in July with the aim of cultivating melon, which is a special product of the city, all year round. In the test, there is a difference in the workmanship depending on the variety, and it seems that the yield and quality of melons are excellent. In winter, I tried three types of lighting to make up for the lack of sunshine, and it seems that LEDs are the most effective because they are economically superior and the amount of light is sufficient. The sixth work that started in June 2022 is “Kimika Melon (Vilmorin Mikado Co., Ltd.)” and “Silk Road Melon (Yamato Farm: Greenhouse, a red meat melon that is suitable for tunnel cultivation and can be cultivated in three dimensions. Resistant to Fusarium wilt (race 0). Fruits are well expressed in the net and occur uniformly and densely, the fruit shape is slightly tall. The flesh is thick and bright orange to the skin. The sugar content is high and stable at 16 to 17 degrees. , The fruit meat is juicy. The ripening period is 53 to 55 days as a guide.) ” It seems that they are cultivating a new variety. It seems that the sixth harvest is scheduled for early September. Tsugaru City is located in the northwestern part of Aomori Prefecture, west of the central part of the Tsugaru Plain. It borders Nakadomari Town, Kitatsugaru District and Goshogawara City on the east side of the Iwaki River, faces the Sea of Japan on the west side, and its coastline is Shichirinagahama. It is called Kodomari, Nakadomari Town and Ichiura, Goshogawara City in the north, and Ajigasawa Town, Nishitsugaru District in the south, and a hilly area called Mt. Byobu continues along the coast. To the south, you can see Mt. Iwaki, the SHUHO of Tsugaru, and the Shirakami Mountains, a World Heritage Site. In the center, you can open up the vast Tsugaru Plain nurtured by the Iwaki River. A large breadbasket has been formed since the reclamation of Nitta by the famous Tsugaru clan. The area is 253.55 km2, which occupies about 2.6% of the prefecture area, and its land use is 56.0% for agricultural land, 4.5% for residential land, 13.7% for forests, and 25.8% for others. The climate is a typical Sea of Japan-type climate influenced by the Sea of Japan, and it is widely known as an area suitable for rice cultivation and summer-autumn vegetable cultivation because it is relatively cool in summer and the outbreak of pests is suppressed. In winter, there is a lot of snowfall due to the continuous strong winter-type pressure distribution, and traffic may be interrupted due to the blizzard caused by the strong westerly wind peculiar to the Sea of Japan, which affects the lives of residents. “Nishitsugaru District（Ajigasawa Town, Fukaura Town）” has been the name of the county since it was divided into five counties: east, west, middle, south, and north with the enactment of the county, ward, town, and village organization law in 1878. A county mayor was assigned to the county, and a county office was set up as its office, giving it the function of a substantial administrative division. Immediately before the enforcement of the municipal system in 1889, 108 villages in 11 towns were counted, but after the enforcement of the system: Ajigasawa Village, Maito Village, Nakamura, Akaishi Village, Naruzawa Village, Wooden Village, Tateoka Village, Shussei Village, Koshimizu Village, Shibata Village, Kawase Village, Fukaura Village, Odose Village, Iwasaki Village, Morita Village, Kashiwa Village, Inagaki Village , Shariki Village, Mizumoto Village, 13 Villages established. With the promulgation of the county system in 1890, the county was stipulated as an intermediate administrative agency between prefectures and municipalities, and a parliament (county council) was established to give it the function of a local government. However, since the county as a municipality (county council and county autonomy) was abolished in 1923, and the county as an administrative agency (gun mayor and county council) was abolished in 1926, the county has become a mere geographical division. It has become. After that, due to the merger of cities, towns and villages in 1955, there were 8 towns and villages. In addition, out of the 5 towns and villages that form this area, 4 towns and villages (Morita village and Shariki village are transitional groups up to 2004) have been designated as depopulated areas, and the outflow and decrease of the population continues. There seems to be. Tsugaru City was born on February 11, 2005 by merging the former Kizukuri Town, the former Morita Village, the former Kashiwa Village, the former Inagaki Village, and the former Shariki Village, and is famous as the ninth city in Aomori Prefecture. The city makes history as a land that was once a barren wetland, and was cultivated by its predecessors with unremitting efforts to confront adverse conditions and various obstacles in order to cultivate new rice fields. The paddy field landscape with fresh greenery in early summer and the magnificent rural landscape with golden rice ears in autumn swaying in the wind are one of the pride of the national ward. The beautiful Mt. Byobu windbreak landscape is the result of more than 200 years of tree planting projects that our predecessors have continued to protect Nitta from the strong westerlies from the Sea of Japan and the dust flying from the large sand dunes. Shichirinagahama: As the name suggests, Nanari Nagahama, which extends from Kawajiri in Ajigasawa to near Lake Jusanko, is a long sandy beach that is over 28 km (about 7 里). Since it is a sandy beach where no one lives, it is a place with a high degree of naturalness (Sakurai, Shishin). On the inland side of the windbreak, there are countless large and small swamps such as Lake Tappi. Brackish water bentos such as Corbicula japonica inhabit the estuary of Lake Jusanko and the Iwaki River. The beautiful Mt. Byobu windbreak landscape is the result of more than 200 years of tree planting projects that our predecessors have continued to protect Nitta from the strong westerlies from the Sea of Japan and the dust flying from the large sand dunes.

The world’s largest buried forest about 28,000 years ago, Japan’s oldest apple tree, and estimated to be about 1,000 years old: There are Fraxinus mandshurica var. Japonica（一本タモ: An estimated 1000-year-old Manchurian Ash. The hump on the trunk is said to look like a woman’s breast, and has been worshiped locally as a “milking god” for some time.）, which is said to be the largest in Japan. International exchange is also active, and it has become a sister city after rescuing the crew of the “Cheseborough（A sailor was dying on the beach, but there was an episode that a woman in the village warmed her skin.）”, a sailing ship in Bus City, Maine, USA, which ran aground in the Sea of Japan (off Shariki) in 1889. At the annual Chessborough Cup Swimming Ekiden Tournament, players from the bus city as well as the whole country participate, and it is said that it is a big event that can be said to be a world tournament. Benche wetlands : One of the representative marshes of Tsugaru National Park, which has an altitude of about 20 m and an area of about 23 ha. Academically valuable coastal low-rise and middle-rise wetlands (wetlands made up of multiple layers of moss). In early June, Hemerocallis dumortieri C. Morren var. Esculenta (Koidz.) Kitam. Ex M. Matsuoka et M. Hotta（ゼンテイカ; Daylily : It is a plant of the lily family, and is derived from the fact that it grows naturally in the Nikko region of Tochigi prefecture and resembles a Hemerocallidoideae Lindley. It is a perennial plant with a height of about 70 cm, and its flowers are dark orange-yellow and are known as one-day flowers that open in the morning and deflate in the evening.）blooms and one side is dyed yellow. Around the end of June, the area changes from yellow to purple in a large community of Iris ensata Thunb. Var. Spontanea (Makino) Nakai ex Makino et Nemoto (1930)（野花菖蒲: A perennial plant of the Iridaceae family that grows in swamps and grasslands. The thick middle veins of the leaves are conspicuous, the flowers are purplish red, and there are thin pale yellow spots in the center.）. This marshland, where various flowers are in full bloom, was designated as one of Japan’s 100 Best Nature in 1983. In the city, efforts to contribute to the sound development of agriculture, forestry and fisheries promoted along with the development of renewable energy power generation facilities: From two large-scale wind power generation companies in the city (Green Power Tsugaru LLC., Mahoroba Wind Power Generation Co., Ltd.), a part of the revenue from the sale of electricity from the wind power generation business will be used as funds for regional promotion measures in the agriculture, forestry and fisheries industry. Received the intended donation. In April 2020, the Tsugaru City Agricultural, Mountain and Fishing Village Revitalization Project Fund Ordinance was enacted and the fund started operation in order to use the donations to finance the expenses used for regional promotion projects in the agriculture, forestry and fisheries industry.

You can enjoy one of the goals of Jomon culture and art, such as 219 national important cultural properties. “Lennon Melon”, Net-based red meat melon that was bred from Takii & Co.,Ltd. seedlings and was born in 2005. The round and fine mesh pattern is beautiful, and the appearance alone is perfect as a gift. The flesh is rich, and the juice has a rich and smooth texture that is ground afterwards. It supports a wide range of cropping types from house to tunnel cultivation, and the growth of vines does not slow down during low temperature cultivation, and it has excellent hypertrophy and stable coloring. It can be sown early, and the flesh has a long life even with late cropping, so it can be used for a wide range of cropping from house to tunnel cultivation. The flesh is thick and marketable, and the seeds are small and the green part of the skin is small, so the flesh is thick and the shelf life is stable. The fruit shape is highly spherical and well-matched, and the thick net is generated stably, so the rate of excellence is high, attracting producers and consumers. The grass is a little strong, but the vines do not grow slowly and the fruit set is stable, so it is easy to make. The ripening period is a 57-60 day type mid-late species. “百笑苦楽分”; Let’s all overcome the pain, share the fun, and let everyone laugh cheerfully; 苦しいことは, みんなで乗り越え, 楽しい事はみんなで分け合い, みんなで朗らかに笑っていられるように; Let’s get over the painful things together, share the fun things with everyone, and make everyone laugh cheerfully.Respect nature, adapt its providence to norms, and exercise the great abilities of living soil. ‘Natural environment farming’; Utilization of “microorganisms with an emphasis on organic matter and ecosystems” from agriculture based on “scientifically synthesized fertilizers and pesticides.” Along with the growing demand for food safety, the sense of danger of environmental destruction caused by pesticides and chemical fertilizers has become widely recognized in society, and the role played by natural farming is highly evaluated.
In Tsugaru City, melons are mainly cultivated in the sand dunes called Mt. It drains well and the temperature difference between day and night is large, so it seems that there is a root for growing delicious melons with high sugar content. Supports a wide range of cropping types from Greenhouse to tunnel cultivation. The growth of vines does not slow down during low temperature cultivation, and it is excellent in hypertrophy and stable coloring, so it can be sown quickly. Also, even with slow cropping, the flesh has a long life, so it seems that it can handle a wide range of cropping from green house to tunnel cultivation.
Tsugaru City’s open-field melons are cultivated in rain tunnels, and are cultivated in a well-balanced manner every year by combining white-skinned varieties and yellow-skinned varieties, centering on net-based melons. Melon cultivation that started around the 1965s. It is characterized by its high sugar content due to the good drainage of the soil in the dunes and the difference in temperature between day and night.
Natural environment farming method (from NPO corporation Natural environment farming method study group (Itadomachi, Utsunomiya City)): Agriculture that utilizes “organic and ecosystem-oriented microorganisms” from agriculture that mainly consists of “scientifically synthesized fertilizers and pesticides”, ( To switch to natural environment farming method). As it is said, “Crop making is root making, root making is soil making”, any crop has roots in the soil to maintain life, so soil making is the basis, and it is also a healthy soil. Not to mention. It is said that there are 1 billion microorganisms in a spoonful (about 5 ml) of soil, and in order to make the ecosystem of these microorganisms advantageous for crop cultivation, we have prepared an ecosystem in which good bacteria predominate, and microorganisms and crops. It seems that the soil conditions will be adjusted so that they can coexist. In the natural environment farming method, such soil is improved to the old-fashioned fertile soil, and improvement is made based on “healthy soil preparation” by utilizing useful microorganisms mainly of organic matter so that stable productivity can be maintained.
