Development of LED plant factory


Japan's smart agriculture is characterized by information technology, which solves the problem of less labor in Japan and realizes the transformation and upgrading of the agricultural industry. Japan attaches great importance to the cultivation of talents, and has successfully transformed and upgraded the agricultural industry with the help of agricultural information networks, agricultural database systems, precision agriculture, bioinformatics, and e-commerce. 

Learning from the development of smart agriculture in Japan can help China's smart agriculture move forward faster and more steadily.

Computer farming during the day, robots on duty at night


Located in Fujita's "Autumn" smart farm in Putian City, Shizuoka Prefecture, Japan, the Autumn Color Farm covers an area of 85,000 square meters and has 12 football fields. There are many vegetable greenhouses up to 6 meters in the park, and the exterior is all glass. The steel frame structure at the top of the greenhouse is also very small, the farm official said, this is to ensure a larger area of light.


Before entering the greenhouse where one of the colorful peppers is grown, the staff wears a plastic jacket, rubber gloves and disinfection of the soles and hands. It is strictly forbidden to touch the plants by hand to ensure that the environment is as sterile as possible.


Rows of plant plants are cultivated in dedicated artificially cultivated soil, and water, nutrient solution, and carbon dioxide are connected through the pipeline from the bottom. The branches of the colored peppers continue to grow along the hanging steel wire, and the staff needs a special lift truck to enter the rows of plants for picking. The humidity and nutrient supply in the greenhouse are controlled by computers.


Qiu Cai Farm Specialist Ito Shengmin said that Qiu Cai Farm was jointly established by a well-known Japanese IT company Fujitsu and an agricultural finance company and a local seed research and development company in Putian in 2016. At present, Qiu Cai Farm has initially realized the high degree of automation of environmental control and the visualization of operation management. The staff can observe the temperature, humidity, and daily light of the greenhouse in real time through multiple displays in the main building to realize remote operation and cloud data. Japanese typhoons are frequent. When a typhoon strikes, the staff can remotely control the skylights in the greenhouse.


In the greenhouse, there are self-service robots walking along the track at night, using LED lights and other equipment to monitor the plants and form a photosynthesis color image for the staff to adjust the temperature and humidity. Ito Shinmin introduced.


Plant factory" into investment hot


The so-called "plant factory" uses the computer to automatically control the environmental conditions such as temperature, humidity, light, carbon dioxide concentration and nutrient solution of plant growth, and realizes mass production of plants in a short period of time and a small space to realize crops. Efficient agricultural systems for continuous production. The concept of “plant factory” first appeared in Northern Europe, but it was first applied in Japan on a large scale. There are currently more than 400 artificial plant factories in the world, half of which are in Japan.
