(57) Abstract:

Usage: agriculture, namely crop production in buildings protected ground. The inventive greenhouse comprises a base 1, a roofing enclosure 2, the system of cultivation of plants, comprising a vertical rectangular frames 3 and placed tiers of trays 4 for plant growth and exposure. The system of cultivation of plants is supplied by a conveyor 6 with endless bearing elements 7 moving along the vertical posts adjacent frames 3, and tray 4 is fixed on the supporting elements 7 of the conveyor 6. While the radiation sources 5 system irradiation placed in such a way that the proportion of light energy in the spectral range from 600 to 700 nm increases with reductions height placement of the radiation source 5 relative to the base of the greenhouse. 1 C.p. f-crystals, 4 Il.

The invention relates to agriculture, in particular, to structures, greenhouse, greenhouses with artificial irradiation.

Known greenhouse, containing a base, side and roof guardrail system with the cultivation of plants, comprising a rectangular vertical frames and placed tiers of trays for Viridian the CLASS="ptx2">

A disadvantage of the known greenhouse is its low productivity, the inconvenience of service, the unevenness of the irradiation plant height.

One of the factors determining the height of the greenhouse is the height of plants in a single-layer boarding and performance greenhouses largely depends on the area of the base (floor). Hung over the plant sources of artificial radiation and natural light unevenly irradiated plants height, for example, remote from the light sources deciduous cover covers weaker and, in addition, the spectral composition of light as the distance changes. As a rule, the intensity of the red component light is markedly reduced, which affects the yield.

Was tasked with creating a greenhouse, which increases productivity and improve the conditions and facilities maintenance.

The claimed invention solved the problem of increasing the height of the greenhouse, increasing the uniformity of irradiation plants, which increases the performance of the greenhouse and improved conditions of service of plants.

In the greenhouse, containing a base, side and roof guardrail system of cultivation rosteritem irradiation plants, includes installed rows of sources of optical radiation, according to the invention, the system of cultivation of plants equipped with conveyors with endless bearing elements, the opposite vertical branches which are located so that they can move along the facing to each other of the vertical posts adjacent rectangular frames, with trays for growing plants is fixed on the supporting elements of the conveyor, and the sources of optical radiation is placed inside a rectangular vertical frames with the increase of the ratio of energy in the spectral range from 600 to 700 nm to the total energy flow in the whole spectrum of radiation of each of the said sources of optical radiation in the range of 38-43% to 62-67% when growing cucumbers, and 65% up to 85% when growing tomatoes when reducing the height of the location of these sources of optical radiation relative to the base of the greenhouse.

In a preferred embodiment of the greenhouse is equipped with a mechanism to move funds perform farming operations, including movable platform mounted for movement in vertical and horizontal planes along the guide rails, which are fixed on the elements of the river incision; in Fig.2 the system will move the platform; Fig.3, the drive of the conveyor; Fig.4 kinematic scheme of the conveyor greenhouse.

The greenhouse contains a base 1, side (not shown) and a roof 2, the fence system of cultivation of plants, which comprises a rectangular vertical frames 3 and placed tiers of trays 4 for growing plants. System irradiation plants set includes rows of sources of optical radiation 5. The system of cultivation of plants is equipped with a conveyor 6 with endless bearing elements 7, are attached trays 4 for growing plants. The opposite vertical branch of the conveyor 6 are located so that they can move along the facing to each other of the vertical posts adjacent rectangular frames 3. The conveyor 6 includes drums 8 with endless bearing elements 7, the drive mechanism 9 of rotation of the conveyor 6, with the pinion 10, the shaft 12 of the cable 11 of the drive mechanism for the rotation.

Sources of optical radiation 5 is placed inside a rectangular vertical frames 3 so that the ratio of the energy in the spectral range from 600 to 700 nm (red light) to the total energy flow in the whole spectrum of radiation of each radiation source 5 increase the height and placement of radiation sources 5 relative to the base 1 of the greenhouse.

For example, when growing cucumbers lamps emit red light" upper lamp 30-35% of the second lamp 40-45% third 45-50% fourth 50-57% lower 57-65%

The greenhouse has a mechanism to move funds perform farming operations, containing movable platform 12, is placed between the frames 3. Platform 12 can move in the vertical and horizontal planes along the guides 13 which are affixed to the elements 14, which connects the top of the adjacent vertical rectangular frames 3. The mobile platform 12 is fixed on the suspension 15 and includes a turning mechanism 16, a drum for winding 17 of the cable, the actuator 18 of the drum 17, the carriage 19, moving on rails 13.

The greenhouse is maintained as follows. Trays 4 with plants at the bottom of the greenhouse set on the conveyor 6, is filled with nutrient solution and moisturize if needed. The conveyor 6 with plants moves up one side of the frame 3 and descends on the other side of the actuator 11 by means of a cable, the gear 12, the drive shaft 13 and the drum 8 on the conveyor 6.

Exposure of plants by natural light through the rack side and roof enclosure 2 greenhouses and from sources of the TKA 21 which moves along the guide rails 15 of the frame 3. Harvest produce at the bottom of the base 1 of the greenhouse.

The use of the proposed greenhouses by increasing its height, improving the uniformity of irradiation plants can improve the performance of the greenhouses and to improve conditions.

1. Greenhouse, containing a base, side and roof barriers, the system of cultivation of plants, comprising a rectangular vertical frames and placed tiers of trays for processing plants, and a system for irradiation of plants, including installed rows of sources of optical radiation, characterized in that the system of cultivation of plants equipped with conveyors with endless bearing elements, the opposite vertical branches which are located so that they can move along the facing to each other of the vertical posts adjacent rectangular frames, with trays for growing plants is fixed on the supporting elements of the conveyor, and sources of optical radiation is placed inside a rectangular vertical frames with the increase of the ratio of energy in the spectral range of 600 to 700 of them to the total energy flow in the whole spectrum of radiation of each of the sources of optical radiation in the range from 38 to 43% to 62tx2">
