Abstract

FIELD: agriculture.

SUBSTANCE: vegetation installation contains a hollow cylindrical chamber, a domed wall and a floor consisting of an outer dismountable translucent wall and an inner stationary translucent wall with sources of light mounted between them. The sources of light are of the spot-type and are separated with horizontal partitions forming rectangular sections horizontally. In the section lower, middle and upper rows spot sources of blue, green and red light are accordingly arranged. Opposite each rectangular section light-diffusing panels are arranged along the perimeter inside the hollow cylindrical chamber between racks with plants and the inner stationary translucent wall.

EFFECT: invention enables improved efficiency of plant growing.

Description

The invention relates to agriculture, in particular to climate chambers for growing plants.

Known vegetation-climatic chamber (RF Patent No. 2283579, class A01G 9/24, 2006 - prototype), including a hollow cylindrical chamber, light sources, fans, moreover, it is equipped with a guide rail for moving light sources, made in the form of a spiral and mounted on top in horizontal plane above the shelves with vegetation vessels, and the fans are connected by means of a flexible hose to the carriage with a light source fixed on it and mounted on a guide rail. The carriage with the light source is made with the possibility of reversing its movement in a horizontal plane along the guide rail.

A disadvantage of the known vegetation-climate chamber is the low installation efficiency, since light sources have the ability to irradiate plants only from top to bottom.

The purpose of the invention is to increase the efficiency of the vegetation plant by providing uniform and controlled lighting.

It is known that the intensity of vertical light drops sharply after the passage of light through the sheet. The top sheet will receive 100% of the light, followed by 20%, the third sheet - only 4%. The depletion of the spectral composition of light is even more significant. In addition, with artificial lighting, it is advisable to arrange the radiation sources so that the radiation falls on the coenoses at certain angles.

It is also known that the spectral ranges of light have the following physiological values:

- 400-500 nm ("blue"): necessary for photosynthesis and regulation;

- 500-600 nm (“green”): useful for the photosynthesis of optically dense leaves, lower tier leaves, dense plant crops due to its high penetration;

- 600-700 nm (“red”): pronounced effect on photosynthesis, development and regulation of processes;

- 700-750 nm (“far red”): pronounced regulatory action, a few percent in the total spectrum is sufficient.

The goal, in contrast to the prototype, is achieved by the fact that the cylindrical chamber, the domed roof, the floor consist of an external removable transparent wall and an internal stationary transparent wall, and the light sources are point-wise and mounted between the external removable transparent wall and the internal stationary transparent wall, and are divided by horizontal partitions, forming horizontally rectangular sections, moreover, in the lower row of the section there are point sources of blue light, in the middle row - point sources of green In the upper row, there are point sources of red light, and opposite to each rectangular section inside the hollow cylindrical chamber between the racks with plants and the stationary stationary transparent wall, light-scattering panels are installed around the perimeter.

In Fig.1 shows a vegetation plant - a general view, in Fig.2. - section aa, in figure 3. - section BB.

The vegetation plant contains a hollow cylindrical chamber 1, on top of which there is a domed roof 2, and below the floor 3, (for example, made of cellular polycarbonate). The hollow cylindrical chamber 1, the domed roof 2, the floor 3 consist of an external removable transparent wall 4 and an internal stationary transparent wall 5 (Fig. 3), between which point light sources 6 are mounted horizontally in a row (for example, LEDs), separated by horizontal partitions 7, forming horizontally rectangular sections 8 (figure 2). Moreover, in the lower row of the section there are point sources of blue light 9, in the middle row - point sources of green light 10, in the upper row - point sources of red light 11. Opposite each rectangular section 8 inside the hollow cylindrical chamber 1 between the racks 13 with plants 14 and the inside light-diffusing panels 12 are installed around the perimeter by a stationary transparent wall 5. A technological opening 15 with a door 16 is provided for access to shelves 73 with plants 14 installed inside the hollow cylindrical chamber 1 (Fig. 3).

The vegetation installation works as follows.

Initially, both point blue sources of light 9, point sources of green light 10, point sources of red light 11 are simultaneously turned on. Light passing through the inner stationary transparent wall 5 of the hollow cylindrical chamber 1, the dome roof 2, floor 3, enters the light-scattering panels 12, where it it is refracted and mixed and the radiation becomes white. Radiation of white light enters the plants 14. The process of irradiation occurs. To control the culture, including the flowering process and the habit of plants for different phases of the development of the culture, point sources of radiation of a certain light are used. For example, to irradiate plants with optically dense leaves, either the leaves of the lower tiers of the plants or dense plantings of the plants include point sources of green light 10. At the flowering stage, blue light is most favorable for plants, therefore, point sources of blue light 9 are included. To obtain plants with a large number of side shoots, include point sources of red light 11.

In the case of repair (replacement of failed) point light sources 6 remove the outer movable transparent wall 4 and make repairs.

The proposed vegetation plant has several advantages:

1. The shape of the vegetation plant in the form of a hollow cylinder, as well as the shape of the roof in the form of a dome, allow the plants to be illuminated at different angles, which increases the uniformity of exposure;

2. The horizontal arrangement of light sources of various emission spectra (blue, green, red) makes it possible to obtain uniform light of a certain spectral composition and control plant growth by stimulating physiological functions;

3. The use of light-scattering panels allows you to do without expensive sources of white light;

4. A removable outer transparent wall allows easy maintenance of point light sources, and an internal stationary transparent wall protects the radiation sources from the effects of the microclimate of the vegetation chamber, which increases the efficiency of growing.

The vegetation plant can be easily implemented in agricultural production, under controlled cultivation of plants in artificial controlled and regulated environmental conditions.
