Introduction to the scale and technology of 4 plant lighting plants in Japan

The concept of plant factories originated in the Nordic countries in the 60s of last century. But let the real plant factory craze in Japan, especially after the 311 tsunami and the Fukushima nuclear disaster, the Japanese government invested 14 billion 600 million yen, hope that through the number of expansion of the plant factory provide reasonable price and green vegetables for national security.

It is understood that the Japanese domestic plant factory has ushered in the third investment and construction boom, as of 3 at the end of 2012, the number of Japanese domestic plant factory has been increased to 127, more than 100 for the confined space of the "artificial light" and "artificial light and sun light and use of" plant factory, "artificial light type plant factory mainly cultivated lettuce, spinach and other leafy crops, artificial light and sun light and the use of" plant factory is mainly cultivated tomatoes, peppers and other crops.

At present, the plant has become the world's factory (especially in economically developed areas) to solve the population resources environment and food safety (non grain crops, the quantity and quality of safety) an important way to develop modern agriculture and other outstanding issues, the. It is believed that after land cultivation, horticulture, hydroponic cultivation according to a new technology development after the order, also known as the "fourth agriculture", the industry known as a revolution in agricultural technology.

Osaka Prefecture University plant factory

The plant plant at Osaka Prefecture University is considered to be the world's most advanced fully artificial light controlled plant factory. It is a model for the production of new plants and a global centre for research and training.

It is understood that the Osaka Prefecture University plant factory center is a research officer innovation group fit. The plant factory by the agriculture and Fisheries Department funded 500 million yen (about 26 million yuan), funded by the Department of economy of 600 million yen (about 30 million yuan), the comprehensive regeneration of science and engineering Osaka Prefecture University Department of environmental science, Department of life, economic department, Osaka forestry and water environment comprehensive production research institute, Osaka Industrial Technology Research Institute of joint venture ITO motor, three metal Industry Corporation, Osaka, came together to build the credit vault. Multi joint research, development, common proposition, joint experiments, confirmed that the project has a common technology, capital to ensure that the risk of joint commitment.

The plant center of Osaka Prefecture University is divided into three units, the first unit accounts for 1000 square meters. Second units also account for 1000 square meters, reinforced concrete construction of the two, for the actual cultivation of leafy vegetables. Third unit has a 1300 square meters, is the production of government research and work together to build a model, showing the latest technology.

The main new technologies of plant plant in Osaka Prefecture University:

1 the world's first selection of seedlings by the robot technology, according to the activity of the seedling time gene to automatically select good seedlings, as well as automatic cultivation of the combined operation of robots;

2 Japan's first introduction of automatic transport robot, as well as automatic handling line;

3 all of the LED light source is used to raise the power consumption;

The 4 air conditioning system adaptation, the cultivation area of each layer have air, making the original source of heat caused by the ambient temperature difference is no longer a problem, and improve the cultivation room temperature is not balanced, can achieve balanced cultivation and production of Vegetable & Fruit.

The University also with relevant units to do a lot of research and development, the various factors affecting plant growth are studied, including the combination of light, temperature, humidity, carbon dioxide concentration, nutrient management, health management, product sales, distribution and market evaluation, reduce the cost and energy etc., confirm, and plant gene regulation of plant The new supersedes the old. precisely controlled.

Chiba University Future Ltd plant factory

Chiba University, Japan, the plant area of 1500 square meters plant, plant production stand three-dimensional overlay of 10 layers, can produce about 100 grams of leafy vegetables per day, 10000. The price of each dish is 20 yuan, the factory is operating normally, breakeven.

In order to make sure that the plants are not damaged by pests, the factory is like a clean room in the semiconductor industry. The workers must wash their bodies before they go in. Because the plant is a sealed space, plant growth is no longer affected by the weather and other natural environment, the supply of vegetables can also be maintained stable. In addition, because it is grown in a clean and dust-free environment, coupled with the use of pesticides, plant plants planted vegetables, can not be directly put into the taste of imports.

Among them, Japan Chiba University of technology research and development in the "plant factory" at the forefront, with more than 30 years in soilless culture, its experience, currently operates 5 solar energy plant factories and 2 man-made light plant factory. Japan's former president of Chiba University Professor Feng in the ancient tree, is the founder and advocate of Japan and the world plant factory technical equipment and industrial development, published the "artificial light", "solar plant factory using plant factory" and other works.

Company's future (Mirai) company has been committed to the development of plant plant technology and commercial promotion. In 2009, it received government subsidies and scientific research cooperation with the national Chiba University of Japan, the establishment of a scale of about 3000 plant test plant. After the success of the experiment, large-scale commercial production began. 2013 set up the future Daejeon (Beijing)
