“please give the pick on march 21st!” at 3. 40 a. M. On march 22, he rubbed his eyes and, after the digital management platform had checked out the manifest with voice, he yelled at the walkie-talkie: “drive!”
He is the manager of kesheng ho-feng (tehzhou) wisdom agricultural co. Ltd. (hereinafter referred to as “kessing ho-fung”). Since november of last year, he had been sending twenty-thousand tons of fresh tomatoes every morning to the shop in chengdu. In the long run, such deliveries will be maintained until mid-august, and the tomatoes will come from 112. 5 acres of glass greenhouses located in tai chi town, on the eastern slope of the city of meishan. It is worth mentioning that tomatoes are not planted in soil, but are planted in the air - glass greenhouses with earthless cultivation techniques。
Smartness and high productivity are the consistent assessment of glass greenhouses by sichuan agro-scientific communities. In their view, the facility agriculture represented by these glass greenhouses is one of the answers to sichuan agriculture's many ways of developing food resources。
Intelligent soilless cultivation
Every tomato is in optimal growth
“the production of a square metre is now only 15 kg and only half of the projected.” on the morning of 22 march, following a review of the data from the harvests, kensheng ho-founding technician li jie concluded that the tomatoes in the glass-temperature room had just reached their production date。
According to lee jie, experimental data indicate that the production of soilless tomatoes per acre is up to and down to 20,000 kg, which is four times higher than the production of tomatoes in general greenhouses。

How do you do that without planting four times the production
“control of key variables.” according to lee, vice-researcher at the provincial agricultural institute, factors affecting crop yields are light, temperature, water and fertilizer. In the glass greenhouse, all these variables are intelligently controlled。
The “valve” of light and temperature is the lamp of the glass in the greenhouse and the roof of the room。
Glass greenhouse look
Li zhi said that the glass used in the greenhouse was “smart”. The glass will enter all the heat into the room without “run off”. Based on the lifetime of tomatoes, the master control room gives the best calorie value for tomato growth per day. Thus, when glass absorbs the caloric amount to this value every day, the curtains are automatically removed. In order to compensate for insufficient indoor light, high-pressure sodium lamps and led lamps on the roof will be automatically turned on。
Fertilizer control, same intelligence。
Journalists noted that each platoon ends with a monitor. On the above, changes in nutrient content, indoor co2 content and humidity are shown in real time. "the monitor connects to the master control computer, which is then controlled at any time." in the case of xu iin, the tomato permafrost period was about 10 weeks in a state of “whatever is missing”, saving half the time compared with the traditional shed。

It's been nine months
It's a good price to sell on the wrong top
"it's good that you pick the same kind, or a few dollars is gone." having seen journalists taste the tomatoes in the glass room, xu was joking. He said that his tomato was now 8 yuan per pound, more than three times more expensive than the market. Of these, the most expensive primary tomatoes are sold at $20 per pound。
According to estimates from xu inflammation et al., the value of tomatoes per acre in glass temperature rooms is expected to reach $300,000, about 10 times that of the general greenhouse shed。
Why is the price of tomatoes in glass greenhouses so high
Tomatoes in the glass room
“stable production and long cycles.” zhong lidong, deputy director-general, rural rural department, maeyama city, described the small fluctuations in tomato production in glass temperature rooms and the nine-month harvest cycle. This means that the harvest period is from november to august of the following year. In other words, not only has the counter-seasonal listing of tomatoes been achieved, but it has also won a preference for higher commercial expectations of supply stability。
Lee jie's memory is so new. He said that around the end of november of last year, kessing was crowded with buyers, “the price per hour was different and higher than it was”. During that time, ordinary tomatoes produced in glass greenhouses were sold at $156。
In addition to a steady production and long cycles, tomato quality is good in glass-temperature rooms. Li zhi said that because of its highly intelligent growth conditions, glass greenhouses were able to produce almost all the world's varieties of tomatoes, “even the same varieties, where they were produced with clear taste and nutritional advantages”
Looking at the first season's good tomato production, hsing has revealed that the next step will be the addition of seven glass greenhouses of the same size to kaesing, bringing the total area under cultivation to 1,283 acres。

Glass greenhouse, making the netherlands a major agricultural exporter
The netherlands is a world-famous agricultural power. Data show that in 2019 the netherlands ' agricultural exports were close to $90 billion, the highest in the world. Of these, the netherlands alone provided 40% of the european union's requirements for vegetables。
Unlike traditional agricultural powers, dutch agricultural production conditions are “bad”: the country's total arable land covers only about 10 million acres; due to its high latitude, the average annual temperature in the netherlands is about 5°c and the frost runs for up to 200 days。
Under such unfavourable conditions, dutch agriculture has chosen to avoid competition with large agricultural countries for food crops, rather than focusing on areas such as higher value added, complex technological systems, vegetables and flowers。
The secret weapon that turns the vision into reality is the glass greenhouse that originated in the netherlands. Since the 1980s, the netherlands has invested heavily in the construction of millions of square metres of glass greenhouses throughout the country and has developed a system of proprietary technologies. On this basis, the netherlands has overcome the ills of low temperature and insufficient light. At present, vegetable production per unit area is more than 10 times higher than in other regions of the same latitude, with more than 20 times the value of the product, and the diversification of vegetable varieties is the first at the same latitude, resulting in the localization of many tropical and subtropical vegetables。
Sichuan may wish to learn from the netherlands on new technologies and ideas for food in facilities agriculture。

Food recipes
I. Tomato fried eggs
Preparation of food products. Two tomatoes, four eggs, a little sugar, a proper amount of oil。
The eggs are scattered, salt and water are added, and the mix is even。
3. Scrap the tomatoes and cut them into small pieces. It's oil in the pot, it's hot, it pours in the egg fluid, and it's made out of a big pile。
