Fujitsu "Autumn Color" Intelligent Farm, located in Iwata City, Shizuoka Prefecture, Japan, covers an area of 85,000 square trees and has 12 football fields. There are many vegetable greenhouses up to 6 meters in the park, all of which are all glass structures outside. There are also very few steel frames on the top of the greenhouse, which the farm official said was to ensure a larger area of light.——LED lighting
Workers wear plastic coats, rubber gloves and disinfect soles and hands before entering one of the greenhouses where colored peppers are grown. It is strictly prohibited to touch plants with hands to ensure that the environment is sterile as far as possible.
Rows of plants are grown in dedicated artificial soils where water, nutrient solutions and carbon dioxide are piped from the bottom. The branches of the peppers grew higher and higher along the suspended steel wire, and staff needed a special lift car to enter rows of plants for picking. The humidity in the greenhouse and the supply of nutrient solution are all controlled by computers.——LED lighting
Ito Shengmin, the farm specialist, said the farm was jointly established in 2016 by Fujitsu, a well-known Japanese IT company, with an agricultural financial company and a local seed research and development company in Iwata. At present, Qiu Cai farm has initially realized the highly automation of environmental control and the visualization of operation management. The staff can observe the temperature, humidity, sunlight and other data of the greenhouse in real time through multiple display screens in the main building to realize remote operation and cloud data. Japanese typhoons are frequent. When typhoons strike, staff can open and close the skylights of the shed by remote control.——LED lighting
Self-help robots walk along the track in the greenhouse at night, monitor the plants with LED lights and other equipment, and form a photosynthesis color image for staff to adjust temperature, humidity, etc. Itou Seungmin said.——LED lighting
"Plant factory" has become a popular investment.
The so-called "plant factory" is to use computers to control the temperature, humidity, illumination, carbon dioxide concentration and nutrient solution of plant growth automatically. In a very short period and a very small space, large-scale production of plants can be realized, and continuous production of crops can be achieved in an efficient agricultural system. The concept of "plant factory" first appeared in northern Europe, but was first applied in Japan. At present, there are about more than 400 artificial plants in the world, half of which are in Japan.——LED lighting
In a two-storey building surrounded by vegetable greenhouses at the National Chiba University Park, a plant factory in Chiba prefecture, Japan, 74-year-old director of the Japanese Plant Factory Research Association, Takashi Koku, said the plant factory was an enclosed environment and staff monitored vegetable growth through a Chiba prefecture-specific "growth management system." Control. It takes about 20 days for the vegetable to grow from the beginning to the seedling stage. On this basis, the harvest will take more than 10 days.——LED lighting
A greenhouse in a 10-person plant factory can harvest 1 million vegetables a year and sell 100 million yen (5.87 million yuan). The plant factory also has a visiting room, with many small plant factories for home and college teaching, the size of a refrigerator freezer, and links to others through an app network.——LED lighting
In recent years, the botanical factory has become a hot target of global agricultural investment. One of the reasons for the increase in investment is, according to ancient times, the large-scale use of LED lamps in botanical factories. In the past, about 25% of the cost of plant factories was electricity, and the use of LED lights led to a sharp drop in electricity charges, thereby reducing investment costs. It is understood that artificial light-type plant factories mainly produce a variety of vegetables, while researchers are concerned about higher value-added medicines, such as Angelica sinensis. In China, there are also plant factories specializing in the production of cosmetic raw materials.——LED lighting
A lesson from Japanese agriculture
In early 2017, the media reported that some plants in Japan were poorly managed, 70% of the profits were difficult, and Toshiba and other large enterprises have withdrawn their capital. Before that, many Japanese farmers went to plant factories to get 70% of the government's subsidies. However, due to the lack of relevant technology, these plant factories went bankrupt after exhaustion of government subsidies. Some commented that this is a negative textbook for China's agricultural development.——LED lighting
In this regard, Gu said that at present, in Japan, the real profit of the plant factory is about 30%. But he said it was not surprising that 70% of the plant factories were in deficit. "The negative effects of the media on new things should not be exaggerated. Fifty years ago, no one agreed that greenhouse vegetables were grown. Today, 80% of Japan's tomatoes and 90% of strawberries are grown in greenhouses."——LED lighting
In addition, lack of funds is also a major bottleneck restricting Japan's agricultural development. Koo says Japan and South Korea are in danger of developing plants because of inadequate investment. Japan's richest man and CEO of Japan's Softbank Group, Sun Yizheng, once invested in an American plant factory, sparked a heated debate, and the world's largest plant factory, built in Fujian by the Chinese LED company Sanan Group and the Institute of Botany of the Chinese Academy of Sciences, impressed Gu Yongshu.——LED lighting
Although Japanese farmers have the meticulous patience of embroidery, the long-standing phenomenon of "fighting alone" in Japanese agricultural enterprises is also a factor restricting their agricultural development and growth. In introducing the original intention of the establishment of the Autumn Colour Farm, Ito Shengmin said that Japan's agriculture in the past existed "directional unidirectionality", "research on research, production on production, circulation on circulation". Take Japan's agricultural breeding model for example, Ito Shengmin tells us that there are only two large-scale seedling companies in Japan, and many small-scale seedling-raising workshops cultivate seeds of good quality, but because of the lack of access to the lower reaches, so the added value is low.——LED lighting
Japanese profit model
In China's agriculture, at least 85% can not achieve two profits. For example, farmers grow 100 acres of wheat, and the core revenue comes from selling wheat. Once there is a slow-moving sale, you have to lose money. But in this respect, Japan's experience is worth learning, one example is Japan, for ordinary rice to find a new profit model. Rice painting in Japan is a direction worth learning.——LED lighting
Tian she village is the originator of the Japanese rice field painting. Inspired by the strange circle of wheat fields, in order to revitalize the local economy and develop tourism resources, the villagers began to produce rice field paintings in 1993. Paddy field paintings have different themes each year, involving both inside and outside Japan, and are very extensive. Nowadays, more than 200,000 people visit the village every year. Even some big businesses came to their doors, hoping to use farmer paintings of paddy fields to advertise them. Paddy field art attracts a large number of tourists during the growing period of paddy field; after the harvest of rice in autumn and winter, rice stalks are turned into works of art, which also realizes the value of paddy field. Paddy field paintings in Japan activate farming. Farmers'income comes not only from sales of agricultural products, but also from creative agriculture.——LED lighting
