Ground - vegetable greenhouse for small forms of economy

The object of the study was a greenhouse for small forms of the economy. The possibility of developing a technical solution for a greenhouse was studied. providing a reduction in energy costs when growing seedlings of vegetable crops in the cold season. Summarized and analyzed methods of growing seedlings used in standard projects of greenhouses and proposed at the level of inventions. In the developed technological solutions. when growing seedlings of vegetable crops. the entire volume of the greenhouse is heated. which causes large heat losses through the building envelope. The inexpediency of the considered analogues for use in seedling greenhouses for small forms of management has been established. Taking into account the noted shortcomings of the considered technologies. a technical solution for a seedling shelving greenhouse has been developed. which provides for heating not the entire volume of the cultivation facility. but only the under-shelf space limited by heat-reflecting screens made of honeycomb polycarbonate sheets. in which the water heating pipe is located. As a means of cultivation. it is customary to use polymer containers with a substrate. peat pots. nutrient cubes from soil mixtures. The thermal regime necessary for the development of seedlings in the plant growth zone, limited by translucent heat-reflecting screens. is created by means of warm air coming from the space under the rack. The proposed technical solution for the greenhouse. according to tentative calculations. makes it possible to reduce heat losses by the structure by about half. In the spring-autumn period. the greenhouse can be used for rack growing of vegetable crops in containers. The proposed technological solutions for the greenhouse are illustrated with graphic materials. Based on the results of the study. an application for a patent was filed.
