Video: We Have Opened A Bio-vegetarium. We Tell You Why You Need It
The idea of biovegetarium is not new; back in the 30s of the last century, a solar vegetarian in Ukraine was invented by a physics teacher Alexander Vasilievich Ivanov. Ivanov developed a solar greenhouse that lets in up to 87% of the sun's rays. Therefore, in it, plants practically did not need additional lighting and additional heat for high fruiting.
The physics teacher managed to put the sun at the service of the harvest. The results of his work are described in the book "Solar Vegetarian": "From an area of 16.5 sq. M. m filmed more than 200 kg of lemons per year. Pineapples and tangerines also grew there. And cucumbers and tomatoes from 1 sq. m collected 43-44 kg. And this required very low heating costs, and even then only in the cold winters of the 40s and 50s."
Vegetarian, unlike a greenhouse, can be used all year round. It is always with a slope, usually with a steepness from 14-16 to 18-19 degrees, thanks to this design, the absorption of solar energy is higher than in a greenhouse in the morning and evening hours in autumn, spring and winter.
In addition, for a vegetarian, one wall must be made capital, you can use a wall as it, for example, at home. The wall plays the role of a reflector and is especially effective when the sun is low in the sky, that is, in the morning, evening and in winter. This will help increase the amount of sun exposure to the soil during this time. A thermos greenhouse can be made deep into the soil, since at a depth of about two meters the soil has almost the same temperature throughout the year.
In general, vegetarians insulate well. A closed cycle of air and heat exchange also promotes heat generation. For this, heating also goes through the heating system in the soil, which usually runs at a depth of 30 cm to a meter.
Such a vegetarian device should ensure a high temperature inside the room, even if it is frosty outside.
Biovegetarium is practically energy-free, but only at temperatures down to -10 degrees, practitioners note. In our latitudes, temperatures down to minus 50 are not uncommon. Therefore, taking Ivanov's best developments as a basis, enthusiasts adapt them to our realities.
In the coming year, in the very middle of January, Dr. Shablina's biovegetarium was opened in Ulan-Ude. The area of the greenhouse-thermos is 540 sq.m.
In his bio-vegetation, despite the fact that it is 30-degree frosts outside, it is comfortable and, what is very important, electricity, water and heating are completely autonomous.
As noted by Pyotr Shablin, general director of NPO EM-Center, the author of Russian EM-technology, several innovations were applied here at once.
- In order for the greenhouse economy to be profitable year-round in our conditions, it was necessary to think over a technology that would allow the greenhouse to function in winter without heating. There is no electric or gas heating, no boiler room. All work is built on solar panels that are outside. With their help, electricity is generated, and in the room along the walls there are solar concentrators, they accumulate heat, - said Pyotr Ayusheevich.
In winter, this allows you to heat the water in the tank, which runs inside the entire walkway and distribute heat through the underfloor heating system, which runs at a depth of about a meter, while the soil also prevents a thick layer of insulating material from freezing. At night, the greenhouse is automatically closed with a covering blanket, which also allows you not to waste heat.
Water is respectively taken from an autonomous well.
Dill has already been sown in the beds, tomatoes will soon be planted with seedlings. At the same time, all seeds are checked in the laboratory so that they are truly GMO-free.
- The idea is to get highly profitable, environmentally friendly products with pronounced medicinal properties without energy consumption for heating. For example, we want to work out the technology of increasing lycopene at least 10 times on tomatoes, lycopene, you know, is the main anticancer substance found in tomatoes, - noted Dr. Shablin.
The area of the thermos greenhouse will soon allow sowing more wheat in the second half of the field. The sprouts of which will be needed for food production by NPO EM-Center.
In such greenhouses, you can grow any crops, not only the usual tomatoes, which, by the way, having been planted once, can be grown to the size of trees and harvest all year round for several years, but also exotic ones, such as grapes. So we expect organic vegetables and fruits, without any pesticides, grown in Ulan-Ude.
A similar greenhouse can be used by farmers for the germination of green fodder and medicinal herbs. Having juicy green food for all types of animals in winter means gains, milk production, and the best egg production. Birds can also be kept in a warm greenhouse. This will allow the farmer to make a profit all year round.
According to the author of the project, Petr Shablin, the construction of the facility cost 15 million rubles, but the operation of the bio-vegetarium is simple and does not require expensive specialists. He plans to build five more greenhouses. In this case, the payback period of the object will be 4-5 years. All this is a guarantee of obtaining products with a low cost.
The construction of bio-vegetariums, allowing to obtain fresh produce all year round, in the light of the prospects of the federal law "On organic products" that came into force on January 1, 2020, is of great importance.
