JA Tamana Compost Center, which is indispensable for agricultural and livestock products in the jurisdiction area, recognizes that “soil preparation” is the most important issue in order to open the prospect of Tamana area agriculture, and livestock activity in 1992. It is being constructed as a countermeasure project. It seems that the business entities were the Tamana City Agricultural Cooperative, the Happy Agricultural Cooperative, and the Tamana City Ohama Town（former Tamana District）Agricultural Cooperative at that time. Compost is important for soil preparation, but it seems that the use of compost is decreasing in cultivated farmers in recent years due to labor shortages and other factors. In order to promote soil preparation, it seems important to promote the distribution and utilization of compost by strengthening the cooperation between livestock and cultivation. In Kumamoto Prefecture, which establishes environment-friendly agriculture under these circumstances, the Kumamoto Prefecture High Quality Compost Co-Exercise Association was held, and compost made at the JA Tamana Compost Center in September 1997, 1999 and 2002 was produced. Received the Keizairen Chairman’s Award. With the construction of the compost center, the excrement treatment of livestock farmers who participated in the project was efficiently and rationally performed, it became possible to produce high-quality compost, and compost was supplied to the farmers in the jurisdiction. Half of the gross agricultural production value in the jurisdiction is horticultural farmers, and the certification of environmentally friendly farmer (as recognized by law), which started in 2001, exceeds 900 houses, and the demand for high-quality compost seems to be increasing year by year. The Tamana area has jurisdiction over Arao City, Tamana City, and Tamana District. Located in the northwestern part of Kumamoto Prefecture, it is roughly divided into three areas: a flat paddy area facing the Ariake Sea, the foot of Mt. Kinpo and Mt. The Kikuchi River runs north and south. The main management items are facility vegetables and rice, wheat, soybeans, etc. mainly in flat paddy fields, fruit trees such as Citrus unshiu, pears in the foothills area, and various agricultural production activities such as livestock in the mountainous areas. It seems that it is. Glitter: It’s the brilliance of the producer’s sweat, and the freshness of the lustrous produce. “Glittering” is a message of passion that JA Tamana sends to future agriculture. The weather conditions are relatively warm areas with an average annual temperature of around 16 ° C, and annual rainfall is around 1,800 mm. In terms of geographical conditions, the Kyushu Shinkansen and JR Kagoshima Main Line run from east to west, the Kyushu Expressway runs through the north, and Kikusui and Nankan Interchange are located in the jurisdiction. In the Itakusukobaru and Nagomi area, which are model areas for mountainous agriculture in the Tamana area, we are promoting the introduction of physalis cultivation as a measure for income in the summer. This year, which is the third work, in order to improve drainage, which is an issue as a countermeasure against white silk disease that occurred frequently in the previous work, it seems that he has given guidance on the construction of culverts and bullet culverts, and also held seminars on seedling raising etc. As a result, field preparation and seedling growth proceeded smoothly, and it seems that planting was possible on February 14 as scheduled. As a result of drainage measures, soil moisture is maintained at an appropriate level, and growth seems to be proceeding smoothly. This year, the area has changed from 3 to 5 a, and there is an increase in motivation for cultivation. From now on, it seems that it will continue to provide guidance on pest control and fertilizer management until the harvest in July, and will support it to secure income in the summer. With the prolongation of the new coronavirus infection, the demand for flowers is declining due to the cancellation or reduction of various events, and it is important to increase purchasing motivation in the region in order to stimulate consumption. For this reason, continuing from last year, from March 3 to March 30, this section and the “Tamana Regional Agricultural Extension Guidance Council Hanaki Subcommittee” planned a total of 14 locations including 6 municipal offices in the jurisdiction, JA, and New Tamana Station. A flower arrangement using locally cultivated flowers was exhibited at the facility. From the institutions and visitors who provided the flowers, they said, “It was very nice that the government building became brighter. I want the citizens of the prefecture to publicize the flowers and decorate them at home.” The Agriculture Promotion and Promotion Division of the Kumamoto Prefectural Agriculture, Forestry and Fisheries Department will continue to support cultivation techniques and measures to increase consumption in order to secure income for flowering farmers. It is one of the leading wheat producing areas in the prefecture. Harvesting work is carried out from late May to early June, and soon after that, rice planting work begins. On the other hand, the wheat straw after harvest is often taken out of the field, and it seems that it is mostly processed without being plowed. For this reason, in order to promote the utilization of “straw”, which is an effective organic resource in soil preparation, the section created a “plow-in promotion leaflet” in collaboration with the local JA and the Agricultural Technology Innovation Support Center. The leaflet summarizes the effects obtained by plowing “straw” into the field and the points for plowing “straw” in paddy rice cultivation, and it is also published in the local JA’s public relations magazine, and it will be normal in the future. It is said that it will promote the effective use of “straw” along with the production of good-tasting rice by improving the soil fertility while distributing it at workshops. On April 9, 3rd year of Reiwa, in the Ogizaki / Onoshimo district of Tamana City, the fifth regional farming corporation “Agricultural Producer Association Taimei” (management area 41.5 ha, 44 members) was established in the city. The district is a paddy field in the western part of Tamana City, and has been working on infrastructure development since FY2014. In addition, it has been designated as a priority district in the prefecture, and it seems that the section has also supported discussion activities for the accumulation of agricultural land and incorporation into the bearers. Activities for incorporation have never been smooth, and it seems that there was a time when the establishment of the organization was at stake because the tomato cultivation, which was considered as a pillar of high-profit crops, was not completed. However, in order to revitalize the region through agriculture, there was a growing voice in the region that it should be incorporated even if there were difficulties, and this time the corporation was established. In the future, along with the production of rice and wheat for main food, we plan to expand new demand rice and WCS, aiming for stable management. The Agricultural Extension and Promotion Division will continue to cooperate with related organizations such as JA and the city to support the stability of management as a corporation. In recent years, the quality of winter and spring tomatoes in the prefecture has become a problem due to the occurrence of “yellowing fruits” that turn yellow on the shoulders of tomatoes as the temperature rises from early spring. For this reason, since last year, we have been working with JA Tamana to identify the causes. From the results of the survey so far, it is thought that yellowing fruits are caused by the rise in fruit temperature due to the temperature rise in the house and direct sunlight, so the Tomato Subcommittee will expand the shading material by May 5. It was said that the entire subcommittee worked on measures to reduce the temperature of the fruits. This year, in order to newly consider measures for the high temperature period, which is difficult to prevent by shading alone, it is said that an exhibition hall was set up to investigate the effects of attracting and bagging to lower the fruit setting position. From the results so far, the effect of attracting is limited, and it is necessary to consider the timing of attracting in the future. On the other hand, although it was found that the effect of bagging is high, there are problems in terms of cost and labor, and it seems that more efficient and effective measures need to be further considered. Since the occurrence of yellowing fruits has been confirmed throughout the prefecture, information is shared with each region and the Agricultural Research Center at the Yellowing Fruit Countermeasures Conference hosted by the Agricultural Innovation Support Center. It is said that it will continue to work in collaboration with related organizations while proceeding with on-site demonstrations to establish yellowing fruit countermeasure technology. Although it is a region where wheat production is thriving, especially in the wheat “Minaminokaori wheat” which is suitable for bread, the section, JA and the actual consumer (Kumamoto Flour Milling Co., Ltd.) will cooperate to brand high-quality wheat products with high protein content. It is said that they are making efforts to increase the income of producers. Appropriate fertilizer production is important to increase the protein content, but the JA High Quality Minaminokaori wheat Production Subcommittee extracted several leaves for each field before the ear-matching period, which is the actual fertilizer period, to obtain leaf color and leaf length. It is said that the appropriate amount of topdressing is calculated by investigating, and each producer is trying to improve the quality by applying actual fertilizer based on it. The wheat cultivation in the jurisdiction produced in the 3rd year of Reiwa showed variations in initial growth due to drying and low temperature after sowing, but after that it was blessed with good weather and management work including actual fertilizer was carried out smoothly, which is good. It became a growth. In July, although the harvest was slightly delayed due to the rain during the harvest season, the yield of “Minaminokaori wheat” was about 1,600 tons (136% of the previous year), of which less than 30% had a high protein content of 12.5. Satisfied over%. Based on this result, the Agricultural Promotion and Promotion Division will collaborate with JA to carry out seminars and top-dressing diagnosis aimed at stable production of high-quality wheat, and brand high-quality wheat products. It seems that we will proceed. “Honey Rosa（White Plum: A representative species of the ancient Japanese Simon plum family. Both the peel and the flesh are pale yellow, and it seems that the sweetness will increase when fully ripened on the tree. It has high yield and may be used as a pollinated tree of other varieties. The harvest season is expected to be from late July to early August.）” is a little small but has a high sugar content and a very good taste. In Gyokuto Town, the introduction was started in 2003, and it is now the number one producer in Japan for cultivating 2 ha. In addition, since the fruits are prone to cracking, we are promoting the introduction of rain shelter cultivation, and currently about 80% have introduced it. In the section, management seminars such as fruit thinning and shoot management were held in April and May in cooperation with JA for stable production of high-quality fruits. At the workshop, this year’s growth was about 10 days earlier than normal, and there were many fruit set, so we called for the most important thing to promote hypertrophy by early fruit thinning, and instructed to plan large ball production. As a result, high-quality honey rosa was produced with good ball growth. Continuing from last year, the PR event “Honey Rosa Harvest Festival” was canceled due to the spread of the new coronavirus infection, but we actively promoted it using media such as TV and newspapers. As a result, the unit price of rain shelter cultivation was about 1150 yen / kg (104% compared to the previous year), leading to high unit price sales. It seems that the section will continue to support the stable production of high-quality fruits as a special product of the town. In the Tamana area, the cultivation of tomatoes (tomatoes, cherry tomatoes) produced in Reiwa 2 was completed on July 19. Currently, preparations are underway for the next crop, Reiwa 3rd year production, such as residue treatment and soil disinfection. It seems that soil diseases occurred in early spring in the 2nd year of Reiwa, because the soil disinfection period could not be secured due to the influence of the rainy season. For this reason, in collaboration with the Agricultural Innovation Support Center, a soil disinfection workshop for JA instructors was held on June 17th. The content of the lecture was highly specialized on the mechanism and countermeasures for the occurrence of soil diseases, and the instructor said, “I want to make sure that the producers are thoroughly aware of it.” In addition, on July 7, a soil disinfection class was held for tomato producers in the JA Tamana rainwater area. The lecture focuses on the concept of soil disinfection measures and effective implementation methods, and producers who are engaged in soil disinfection every year also said, “I want to review effective soil disinfection methods.” It seems that he was able to get a firm understanding of the measures for the work. It seems that the section will continue to work in cooperation with related organizations toward the more stable production of tomatoes, which is the main crop in the area. Until now, there was no variety that could be shipped in late September, which is expected to have a high unit price, so it is a new variety that is easy to cultivate and has good fruit quality, and can be relay-shipped to “Wase Toyofu mandarin” in early October. The tree vigor is the strongest in the very early Citrus unshiu. The harvest time is from the end of September, and it can be shipped before “Wase Toyofuku mandarin”, which is shipped in early October. The fruits are well-colored, with 4-6 minutes in late September and complete coloring in early October. The juice has a high sugar content, low acidity, and a good taste. By the end of September, the sugar content will be 10 degrees or more and the acidity will be about 1%. The cultivation area is suitable for warm areas where the features can be exhibited even if shipped early. One of the middle-aged varieties is “Sakamura No. 1 mandarin”. This is an original variety born in the Tamana area. At the time of 2015, it was completed by cultivating non-defective products made by mutation in the trees of producers who grow mandarin oranges in the area. This Sakamura No. 1 mandarin is not only good in taste but also difficult to float. Floating skin seems to be one of the factors that significantly reduce the quality. In that respect, Sakamura No. 1 mandarin, which has high storage stability, is the most suitable variety for gifts, and is wholesaled to the market as a variety that is one rank higher than general Citrus unshiu. The annual yield is still about 170 tons, but the market evaluation is so good that the supply cannot keep up. Both citrus subcommittees of JA Tamana Chuo and Tensui in Kumamoto Prefecture have embarked on a variety renewal using a type of graft, “high grafting”. The advantage is that it can be harvested faster than the method of cultivating from seedlings. Expected two years from now. The subcommittee hopes to quickly shift to varieties that are expected to be in demand for year-end gifts and gifts, which will lead to the early realization of production expansion. Until now, both subcommittees have had the problem that there are few varieties shipped in December, which are in high demand. In late March 2018, 22 members, including subcommittee officers and JA staff, worked toward the establishment of a high-joint work group. At about 10 ares of the garden of Jun Sakamoto, the chairman of the Tensui Citrus Subcommittee in Tensui Town, Tamana City, 100 rootstocks of Satsuma mandarin “Hi no Akebono mandarin” were grafted with the scion of “Sakamura No. 1 mandarin”. Has a high sugar content and few floating skins, and can be shipped in early December. This is the first attempt at joint high-joint work. In the future, it seems that a working group will be formed by the officers of the subcommittee, the youth club, and JA staff, and the high ties will be promoted in the garden of the applicant. By collaborating with the group, it seems that the work load can be reduced and the inheritance of high-connecting technology can be expected. The Citrus unshiu produced in the 3rd year of Reiwa has a high spring temperature, and it seems that flowering is about 10 days earlier than normal. Flowering is generally good, and there are many fruiting even after menstrual fruit drop, except for mid-late varieties. Therefore, it seems that the section is cooperating with JA to hold a seminar to improve the quality according to the growing conditions of the 3rd year of Reiwa, which has a lot of fruit set. Specifically, it is said that it provides guidance on fruit-picking techniques using plant growth regulators, sugar-increasing measures, and rough-picking and finish-picking according to the fruit-bearing situation. In addition, as a measure against sugar increase, early coating of mulch (approaching 7 to 10 days earlier than normal except for some parts) was planned, and the coating status and fruit set status of each garden were confirmed. That’s it. Currently, it is blessed with good weather, the hypertrophy is slightly larger than normal, and the sugar content is higher than normal, and it is going well. In mid-September, the shipment of “Hi no Akari mandarin”, which will be the top batter in the production area, will finally begin. It seems that JA and other related organizations will work together to ensure thorough finishing management so that high-quality orange relays can be shipped to the end. In the Citrus unshiu cultivation area, it is suitable for a garden that is warm, has good sunshine conditions, and has good drainage, and more characteristics can be exhibited by performing sheet mulch cultivation. Until the result stage, efforts are made to remove the thorns and secure the number of leaves, but the thorns gradually disappear when fruiting begins. In addition, it is necessary to take a slightly open tree shape to promote fruit set. As a result, the fruits tend to be a little small at the beginning, so we will try to pick the fruits early. As a measure against viruses and viroids, it seems that scions will not be collected from high-joint trees. Very early-maturing Satsuma mandarin “Fertilizer light; Hi no Akari mandarin” is a cultivar of embryony embryony, and in the early stage of the result, the tree vigor is strong and the shoot growth is vigorous. For this reason, when new shoots occur frequently and the rate of new leaves is high, even if flowering is observed, physiological fruit drop is promoted due to nutrient competition with new leaves, and fruit set tends to be insufficient. From the Ministry of Agriculture, Forestry and Fisheries variety registration website: Application number 14210 Application date 2001/12/25 Date of application publication 2002/03/25 Registration number 12297 Registration date 2004/11/08 Duration of breeder’s rights 25 Year. Name and address of cultivar registrant Kumamoto Prefecture (Suizenji, Kumamoto City, Kumamoto Prefecture): Name of the person who cultivated the cultivar Mr. Akira Isobe, Mr. Minoru Mitsuda, Mr. Kensuke Fujita, Mr. Sakanishi, Mr. Kai Shigeoka, Restricted exports No country. This variety was cultivated from the nucellar embryony of “Ninan No. 1 mandarin”, and the fruit shape is slightly flat, the weight of the fruit is light, and the skin color is dark orange (Matsubase Town, Shimomashiki District, Kumamoto Prefecture). In the town, it is a Wenzhou mandarin orange that matures in early October. The shape of the tree is medium, the size of the tree is medium, and the tree vigor is a little strong. The thickness of the shoots is thick, the internode length is long, and the thorns of the shoots are many. The shape of the leaf blade is spindle-shaped, the degree of wavyness is weak, the leaf size is medium, the leaf height is long, the leaf blade width is wide, and the sharpness of the net vein is clear. The shape of the wing leaf is trace, and the length and thickness of the petiole are medium. The formation of inflorescences is solitary, the weight of flowers (flower buds) is medium, the shape of petals is spindle-shaped, the length and width are medium, the color is white, the number is 5, and the degree of separation of pollen is partially united. , The amount of pollen is small. Fruit shape is slightly flat, fruit shape index is medium, fruit top shape is flat, with or without radial grooves, presence or absence of concave ring is unclear, fruit stem shape is cut plane, some radial grooves Is nothing. Medium fruit core, large size, light fruit weight, dark orange pericarp, medium size and density of oil vesicles, flat unevenness, smooth pericarp, The thickness and pericarp ratio are medium, and the difficulty of peeling is easy. The hardness of the sac is slightly soft, the shape and size of the sac are medium, and the color is dark orange. The juice is medium, the sweetness is high, the acidity is low, the aroma is medium, the number of seeds is absent, and the number of embryos is multi-embryo. The germination period and flowering period are early, the maturity period is quite early, and it is late September in the growing area. Biennial bearing and floating fruit occurrence are medium, fruit cracking is absent, and storability is short. Compared with “Nichinan No. 1 mandarin” and “Wase Toyofuku mandarin”, the distinction is recognized by the early maturity period and high sweetness.
According to NARO, Hi no Akari mandarin orange is suitable for warm, sunny and well-drained gardens in the Citrus unshiu cultivation area, and it seems that more characteristics can be exhibited by cultivating sheet mulch. Until the consequential stage, efforts are made to remove the spines and secure the number of leaves, but the spines seem to gradually disappear when fruiting begins. In addition, it seems necessary to take a slightly open tree shape to promote fruit set. As a result, the fruits tend to be a little small at the beginning, so it seems better to try early fruit picking. Also, as a measure against viruses and viroids, it seems that scions will not be collected from high-joint trees.
The tree vigor seems to be the strongest in Goku-Wase Wenzhou. The harvest time is from late September, and it seems that it can be shipped before the Wase Toyofuku mandarin, which ships in early October. The fruits are well-colored, and it seems that they will be completely colored in 4 to 6 minutes in late September and in early October. The juice has a high sugar content, low acidity, and a good taste. In late September, the sugar content is 10 degrees or more and the acidity is about 1%. I’ve heard that the cultivation area is suitable for warm areas where the features can be exhibited even if shipped early.
Speaking of tangerine fields, it is an image of terraced fields with a series of stone walls, but the sunlight illuminates the tangerine trees, and by stacking stones in the back, the sunlight is reflected by the stones and becomes scattered light, which gently It seems that it can deliver light to trees. In addition, it is well drained and the trees grow well when air enters, so it seems that they are cultivated with stone walls. It seems that each fruit picking and harvesting is done manually. It is widely known as a rare mandarin orange, which is a specialty of Kumamoto and is shipped from the time when the outer skin is still blue. It seems to be the mandarin orange that ships the earliest and starts the orange season. It is a new variety that was first shipped in 2007, and I heard that it is difficult to cultivate and it takes a lot of time and effort. The size is a little small, but the scent is very good, and many fans are looking for this.
