The world's only year-round greenhouse built on permafrost is selling vegetables

Abstract: located in Yakutsk, the world's only year-round greenhouse built on permafrost, the first crops planted in Yakutsk have been sold recently, which has impressed local residents

located in Yakutsk, the world's only year-round greenhouse built on permafrost, the first crops planted by Yakutsk have been sold recently, which impressed local residents

it is reported that in February this year, the first batch of about 36kg tomatoes produced by the greenhouse were sold out at the ilinger grocery store in Yakutsk, the coldest city in the world, in only two hours

Yakutsk, a city located in the depths of belia, a high-performance plastic solution for battery shells, is located in Sikorsky, Russia. How cold is it? Just look at the following photos and you start to tremble:

it is said that in the coldest January, its average temperature is about minus 40 ℃, which is a veritable "cold city"

however, thanks to the greenhouse with LED lighting, the residents of Yakutsk city and the whole Yakut (Yakutsk is the capital of the Yakut Autonomous Republic of Russia) can eat fresh pollution-free vegetables all year round. It is reported that Japan was the first to promote the LED greenhouse technology to this city

chekin, chairman of the government of the Republic of Yakut, said that when the Yakut delegation visited Japan in may2015, it first introduced the project with the same test block for hld530. In march2016, a bilateral letter of intent for the implementation of the project was signed in Yakutsk

the project was formulated by the Yakutsk municipal administration and the "diamond trade bank" joint stock company, with the support of the government of the Republic of Yakut and the introduction of the Japanese investor "Hokkaido Corporation"

Nikolayev, the mayor of Yakutsk, said that Japan's "Hokkaido company" is one of the investment partners of the project. The reason for choosing Japanese companies is that they have rich experience in building such projects under low temperature conditions. The project is located in syrdakh village in the suburb of the city, covering an area of 3.3 hectares. When it is fully put into use, it will ensure that 40% of Yakutsk city and surrounding areas will adopt self-lubricating bearings to replace the vegetable supply of hydrostatic bearings. The project is expected to be profitable within six years

the greenhouse uses LED lighting for lighting

it is reported that when the greenhouse in Yakutsk reaches full capacity, 470 tons of tomatoes, 1692 tons of cucumbers and 28 tons of lettuce will be produced every year

Nikolayev said: "when I first heard that the temperature in Yakutsk in winter dropped to minus 40-50 degrees Celsius, and a large number of greenhouse vegetables could also be planted, I laughed doubtfully. When I saw the detailed description of the project, I began to think about this idea. After meeting Japanese engineers, I believed in this possibility."

building greenhouses and plant factories in extremely cold regions will further test agricultural technology. The greenhouse is completely constructed in accordance with Japanese technology, using three layers of thermal insulation materials with a transmittance of 94%. The plants grow on mineral wool, and each plant is drip irrigated in strict accordance with plant habits. The greenhouse microclimate can be fully adjusted automatically, which can shorten the fruit ripening time

on a day when it is minus 45 degrees outside, the thermometer inside shows a mild 19.9 ℃

he said: "this project can be called a success, because now it is minus 45 ℃ outside, but all kinds of tomatoes can grow inside. The most proud thing is the content of nitrate." Nitrate and nitrite in vegetables are harmful chemicals to human body and shall not exceed the standard

"the nitrate content of vegetables in other parts of Russia is 80-100 mg/kg. However, the tomatoes in this greenhouse are only 17-22 mg/kg, just like Japan. This means that these vegetables are truly ecological and clean, and are beneficial to the health of children and adults."

in December 2016, he collected the first tomato from Sayuri experimental center in syrdakh village

The opening of the greenhouse is undoubtedly a major event in the Republic of Yakut. At present, the Republic is actively implementing the federal investment mechanism for large projects. The greenhouse project is the only one that can Confirm the unique items that the power supply is used for years under the specified voltage and safe grounding conditions of extreme low temperature and permafrost

the Hokkaido company behind the project said that Russia's "smart agriculture" has matured. Yukio Temma, general manager, said that natural conditions and the availability of fossil resources make Russia the best country to develop smart agriculture. He said: "Russia is a country rich in natural gas and biological resources. Its vast territory is also the best condition for developing" smart agriculture. "

"together with the project of building greenhouses and the Danube River, we will provide the concept of intelligent agricultural city to major cities in Russia." He said
