Abstract

FIELD: agriculture.

SUBSTANCE: vegetation installation comprises hollow cylindrical chamber and sources of light. Cylindrical chamber, dome roof, floor consist of external detachable transparent wall and inner stationary transparent wall. Sources of light are arranged as spotlight, are mounted between external detachable transparent wall and inner stationary transparent wall and are separated by vertical and horizontal partitions, forming sections shaped as squares. In the left upper corner of square-shaped section there are spotlight sources of blue light, and the right upper corner - spotlight sources of green colour, in the left lower corner - spotlight sources of red colour, in the right lower corner - spotlight sources of white colour.

Description

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

Known vegetative-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-like and mounted between the external removable transparent wall and the internal stationary transparent wall, and separated by vertical and horizontal partitions, forming sections in the form of squares, moreover, in the upper left corner of the section in the form of squares there are point sources of blue light, then in Rabbi top corner - point sources of green light, after the lower left corner - point sources of red light, then in the lower right corner - point sources of white light.

Figure 1 shows the vegetation plant - a general view, figure 2 - section aa, figure 3 - section bb.

The vegetation plant comprises a hollow cylindrical chamber 1 (Fig. 1), on top of which there is a domed roof 2, and on the bottom floor 3 (for example, made of cellular polycarbonate). A hollow cylindrical chamber 1, a domed roof 2, 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 (for example, LEDs) are mounted, separated by vertical and horizontal partitions 7, forming sections in the form of squares 8 (figure 2), moreover, in the upper left corner of the section in the form of squares 8 there are point sources of blue light 9, then in the upper right corner there are point sources of green light 10, after in the lower left corner there are point sources of blue light red light points 11, then in the lower right corner - point sources of white light 12. To access the racks 13 with plants 14 installed inside the hollow cylindrical chamber 1, a technological opening 15 with a door 16 is provided (Fig. 3).

The vegetation installation works as follows.

First, the point sources of white light are turned on 7. Light passing through the inner stationary transparent wall 5 of the hollow cylindrical chamber 1, the domed roof 2, floor 3, enters the plants 14 at various angles. The irradiation process is taking place. 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.

For scientific experiments, for example, to study the effect of blue light on plants, only point sources of blue light 9 are included in the work, to study the effect of green light on plants, only point sources of green light 10 are included in the work, etc. A combined inclusion of point light sources 6 is possible: for example, point sources of blue light 9, point sources of green light 10, point sources of red light 11, and point sources of white light 12 are turned off at the same time. Or, only at the same time, point sources of green light 10 and point sources of red light 11 are turned on, and point sources of blue light 9 and point sources of white light 12 are turned off, etc. Such combinations of switching on light sources are of great importance in scientific research to identify the optimal ratio between the spectrum and radiation intensity in works on the experimental substantiation of the photobiological radiation efficiency in light culture.

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 location of light sources of various emission spectra (blue, green, red, white) in the corners of sections in the form of squares makes it possible to obtain uniform light of a certain spectral composition and control plant growth by stimulating physiological functions;

3. 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.
