2.1 Short description of the Technology

Definition of the Technology:

Growing crops in solar greenhouses to support a year round crop yield.

2.2 Detailed description of the Technology

Description:

Solar greenhouses can be used all year round irrespective of weather conditions, especially in the winter period, when farmers are able to grow vegetables by using natural heat energy. The greenhouses provide a good growing environment as they are insulated and make use of passive solar energy.
This solar greenhouse has three walls which reflect the sun's rays and accumulate heat. The front wall is heat-insulated. Two walls are black and one is white.

Purpose of the Technology: Protect plants from spring and autumn cold spells, including frosts. Extending the natural growing season.

Establishment / maintenance activities and inputs: Selection of the structure of greenhouse, selection of crops, effective ventilation and watering, use of agrotechnology, pest and disease control. Soil control: regeneration, disinfection, mulching, biohumus and drip irrigation in greenhouses.

Natural / human environment: This type of greenhouse can be used for many years in extreme climate conditions, saline soils, unpredictable weather (frosts) and with lack of water resources.
