Cultivation of tomatoes in Mishima began in the latter half of the 1945s, and in the 1955s, the number of greenhouse growers increased. Since the 1980s, many new technologies such as hydroponics have been introduced. The Shizuoka Agriculture, Forestry and Fisheries Certification System is a system started by Shizuoka Prefecture in 2006 with the aim of ensuring the peace of mind and trust of the citizens of the prefecture for agriculture, forestry and fishery products. It is a system in which the prefecture certifies the efforts of producers of agriculture, forestry and fishery products for safety and security, and is targeted at individuals, corporations or production organizations that produce agriculture, forestry and fishery products in the prefecture. Items subject to certification are agricultural products (vegetables, rice, fruit trees, green tea, flowers), special forest products (mushrooms), livestock products (dairy cows, beef cattle, pigs, hens, broilers), marine products (eels, sardines, etc.) Inspiration). It seems that other items will be gradually expanded. A certificate will be issued to those who have passed the certification examination conducted by Shizuoka Prefecture. The certification validity period is three years, and it seems that regular audits are conducted to see if the certified system is operating properly during this period. Those who have obtained the certification are allowed to register on the dedicated website “Fuji no Kushizuoka Food Information Center” to send out information on production and safety management, and to use the certification mark. JA Mishima Kannami is a target item mini tomato with a certification date of March 18, 2021. This certification system requires that a PDCA (Plan, Do, Check, Act) management system be implemented in order to ensure and continuously execute safety management, etc., and certification holders must use manuals and records. Prepare documents etc. This makes it possible to properly explain the producer’s safety management efforts to consumers and the like. It seems that the prefecture conducts an annual examination to confirm that the system for ensuring the safety of certified persons is properly operated. This enhances the reliability of the system. Disseminate information on certification and efforts for safety and security by utilizing certification marks. This seems to be able to effectively lead to the peace of mind and trust of consumers.
Since tomatoes are produced in greenhouses, it seems that the number of tomatoes planted in one house is fixed to some extent. Therefore, it seems that the decisive factor is how much the yield can be increased. Even now, MC (Integrated Environment Control: Control by linking multiple devices such as skylights, heating, and curtains. Creates a balanced environment without waste according to changes in the weather such as wind direction, wind speed, and solar radiation. Greenhouse measured with the set contents Control based on internal and external data. For example, in the afternoon of a day when solar radiation is strong and photosynthesis is active, the control temperature of the skylight and heating can be automatically corrected to promote the translocation of sugar produced by photosynthesis. It seems. It is expected that the optimum environment will be created by making an integrated judgment instead of making a judgment based on one environmental factor, and it is expected that the quality will be improved and the yield will increase. Since it automatically controls the opening and closing of skylights and curtains, heating, etc., it was said that it was opening and closing while watching the weather every day, changing the timer setting frequently, and rushing to the green house when it rained. Reduces the work load on the person. The work efficiency is improved because it is used for work such as the care of crops. Also, the input resources are used efficiently. For example, when the temperature inside the greenhouse is low and the skylight is closed. Applyes carbon dioxide gas at a high concentration to promote photosynthesis, and when the skylight starts to open due to a rise in temperature, the concentration is lowered to stop unnecessary application, and resources are used efficiently.), Fertilizer management, water management, etc. It seems that some farmers are promoting IOT with methods that do not involve human hands as much as possible.
The JA jurisdiction is blessed with a warm climate with a lot of solar radiation even in winter, with an average annual temperature of 16.2 degrees Celsius and an annual rainfall of 1826 mm. About two-thirds of the area consists of mountainous hills, which are roughly divided into hills with the foot of Mt. Hakone at the top and flat lands formed by the Kano River basin on the south side. In the plains, it is a paddy field area, and it seems that facility horticulture such as strawberries and tomatoes has been actively carried out. In the hills on the west side of the western foot of Hakone, a wide variety of vegetables such as potatoes, carrots, sweet potatoes, Chinese cabbage, and lettuce are produced. This area of surface humus andosols is blessed with fertile soil and has a history and romance that has produced very good quality agricultural products since ancient times.
