At 23:00 Beijing time on November 20, the 22nd FIFA World Cup officially kicked off in Qatar.
In addition to the fact that this World Cup is held in winter, there is also a special place, that is, how high is the "medium content", known as the World Cup with the highest "medium content"?
In fact, in this Qatar World Cup, from stadiums to new energy buses, there are China's shadows.
The Luceral Stadium where the final was held, built by China Railway Construction,
Chinese technology enterprises provide LED screens;
The new energy buses used are provided by Golden Dragon Automobile and Yutong Bus:
Fan Village Container Hotel is built by Guangdong Zhejiang Enterprise:
……
Even during the game, the vegetables eaten by the players were grown with the help of Chinese agricultural technology. Below, let Xiaobian take you to appreciate the agricultural black technology of the "country of local tyrants"~
Geographical conditions limit Agricultural development is difficult
Qatar, located on the southwest coast of the Persian Gulf, is a full-fledged desert country, which is controlled by the subtropical high pressure zone and the trade wind belt all year round, with high temperatures and little rain all year round, and severe water shortages, so the development conditions of agriculture and animal husbandry are poor, and the output is small.
In addition, Qatar has many deserts throughout the country and lacks natural arable land, making it difficult to maintain self-sufficiency in food, vegetables and meat, mainly relying on imports.
Therefore, in recent years, Qatar has increased investment in agricultural development, encouraged the development of agriculture, provided free seeds, fertilizers and agricultural machinery to farmers, called for afforestation, expanded cultivated land, and introduced China's intelligent LED plant factory, relying on economic and scientific and technological forces to develop modern agriculture.
Tech Farm Alphadan
Dozens of kilometers north of Doha, Qatar's capital, several vegetable greenhouses are scattered here, the famous Al Fadan, a vegetable farm in the desert.
Compared with the surrounding yellow sand, the vegetable greenhouses in the production block are full of various vegetables arranged in an orderly manner and in different growing stages. Instead of being grown on the ground, these vegetables are planted in soilless multi-layered cabinets, and each row of growing vegetables is equipped with slender tubes that "water" these tubes are not water, but nutrient solutions for the growth of vegetables.
At the top of the greenhouse, a variety of lamps are installed, which can adjust the color and intensity of light according to the needs of plant growth, and at the same time, there are air conditioners, sensors and computers in the greenhouse to control temperature, humidity, light, etc.
Previously, Qatar's leafy greens were all imported, shipped from the Netherlands or elsewhere in Europe, and it took at least 5 days from soil to table, but here, 2 hours is enough. Moreover, the price of imports is high, taking Shanghai Qing as an example, Shanghai Qing grown on Alphadan Farm sells for 40 calories (about 79 yuan) a kilogram in supermarkets, which is cheaper than imported.
The comprehensive agricultural planting techniques such as hydroponics and vertical cultivation technology used by Alphadan Farm have greatly improved land utilization, and the variety of vegetables has also developed from two varieties of rapeseed and one lettuce three years ago to more than 30 high-priced varieties in the Qatari market, including 6 kinds of lettuce, 4 kinds of kale, 5 kinds of peppers, cabbage, spinach, celery, etc.
The success of the smart LED farm has attracted social attention, and Qatar TV and other media have interviewed and reported on it.
Science and technology are constantly evolving, and assumptions that we can hardly imagine now may become commonplace in the near future.
From traditional to modern, agriculture has gradually developed into smart agriculture with Internet of Things, cloud computing, and precision technology, using the best resources and the least cost input to achieve the intelligent management level of production, transportation and sales.
