The invention relates to agriculture, in particular the production of vegetables is in greenhouses multilevel narrowshelving hydroponic plants in artificial light ("the greenhouse Project pl. 1190 m2with tiered narrowshelving hydroponic technology at the farm "Suburban" , Syktyvkar, , eagle, Giproniselprom, 1989).

The disadvantages of this method are the low coefficient of light utilization and low productivity of cultivated plants.

It is also known that laser radiation stimulates the production of plants, increases the biomass development (Bezverkhny W. M. Rural profession of the laser beam. M: Agropromizdat, 1985).

The closest technical solution chosen for the prototype is the method of growing plants in greenhouses with artificial radiation of the mercury discharge lamps [1].

The disadvantage of this method is that the canopy of plants absorbs only 1...5% of the energy of light in the spectral range of photosynthetically active radiation (PAR) and, consequently, inefficient use of energy radiation of the lamps, and therefore low productivity of cultivated vegetables.

The task was to provide a method of growing plants in which more efficiently use the energy of the artificial radiation that will affect the period of plant growth and crop yield.

Zayavleniya cover sheet of light energy in the spectral region of the HEADLAMP, that stimulates plant growth and, consequently, shorten the growing season and increases productivity.

In the method of growing plants in a greenhouse on a multi-narrowshelving hydroponic plants, which are planted seedlings in a tray with nutrient solution and cultivated plants with artificial irradiation, according to the invention, the plant additionally irradiated with laser light, which serves in conjunction with artificial lamp irradiation in the visible region of the spectrum with two sides, through the scanning angle and the reciprocating movement along the surface of the cenosis, with an integrated laser radiation, which serves a full range spectral range of the HEADLIGHTS light 380-710 nm and/or ultraviolet radiation in the range 230-380 nm.

The invention achieves the following technical result.

Irradiation plants more monochromatic laser radiation creates an excited state of the molecule, which is best absorbed nutrients, i.e., stimulates the growth of plants and, consequently, shortens the growing season.

Joint exposure Iskusstvo cover plants to absorb energy in the spectral range of the HEADLIGHTS and, consequently, increases the energy use of artificial radiation.

Supply artificial radiation in the visible spectrum and laser radiation simultaneously from both sides on the cenosis creates the best lighting conditions and the absorption of its cover sheet and, consequently, stimulates its development.

Supply of laser radiation so that simultaneously carry out the scanning angle and the reciprocating movement along the surface of the cenosis, provides uniform irradiation of the entire surface of the cenosis - inner, outer, left, right, and horizontal (bottom, if available).

The integrated irradiation with laser light, which serves a full range spectral range of the HEADLIGHTS light (380-710 nm), allows to achieve the highest photosynthetic and production activities for specific crops, because the laser radiation in this range stimulates the production of plants, increases the biomass development.

The irradiation with ultraviolet radiation in the range 230-380 nm improves the efficiency of light, i.e., creates conditions for a more rational use of energy discharge lamps and Sun (iskusstvennosti hydroponic plants, when the trays are planted seedlings and cultivated with artificial irradiation differs from known, taken as a prototype, the fact that the plant is additionally irradiated with laser light, which serves in conjunction with artificial radiation in the visible spectrum with two sides, through the scanning angle and the reciprocating movement along the surface of the cenosis, when it is irradiated with integrated laser radiation, which serves a full range spectral range of the HEADLIGHTS light (380-710 nm) and/or ultraviolet radiation in the range 230-380 nm.

Comparative analysis of the claimed solution with the known leads to the conclusion that the proposed technical solution meets the criteria of the invention of "novelty."

Of patent and technical literature for the specialist does not know the way in which laser radiation with an artificial lamp irradiation irradiated cenosis with two sides, through the scanning angle and the reciprocating movement along the surface of the cenosis, and is irradiated with integrated laser radiation full range spectral range of the HEADLIGHTS light 380-710 nm and/or by ultraviolet radiation in the meets the criteria of the invention "inventive step".

The proposed solution can be used in agriculture, it can improve the absorption sheet cover plants energy of light in the spectral range of the HEADLIGHTS, and consequently, to stimulate its growth, to reduce the growing season and increase yields by 8-11%. Thus, the proposed technical solution meets the criteria of the invention "industrial applicability".

In Fig. 1 shows schematically a cross-section hydroponic setup with sources of radiation; Fig. 2 is an example of the total spectral composition of the radiation flux of the lamp, Solar and laser.

Narrowshelving stacked hydroponic plant 1 (Fig. 1) is equipped with 2 racks that have trays with plants (not shown). Hydroponic plant 1 will be equipped with a system of external and internal exposures of plants using mercury discharge lamps with 3,4 reflectors 5, and package scanning lasers 6 installed between (top) hydroponic units 1 and package scanning lasers 7 installed inside (bottom) of the units 1. Scanning lasers arranged in packets consist of a resonator, provided with baffles continuous deviations.

In the package is tralnoj region HEADLIGHT light (380-710 nm) or certain ranges, optimal for a particular phase of development of plants, creating together with mercury lamps 3, 4 optimum irradiation crops.

The method is as follows.

Plants are grown in the racks 2 hydroponic installations 1 is irradiated simultaneously mercury discharge lamps 3,4 and scanning lasers 6, 7 are arranged in packages.

When scanning across the corner of the package of the laser 6 is formed of the outer beam that sequentially moves along the outer surface of the cenosis - first top-down on the right cenosis one hydroponic setup, and then from the bottom up on the left cenosis neighboring hydroponic setup. Then moves back. And then a similar way.

When scanning across the corner of the package of the laser 7 is formed of the inner beam that sequentially moves along the inner surface of the cenosis one hydroponic setup - first, bottom-up left cenosis, and then from bottom to top on the right.

Then moves back. And then a similar way.

At the same time the lasers 6 and 7 are moved along the surface of the cenosis reciprocating (back and forth) and thus external and internal is cunosti radiation packages lasers is determined from the ratio:

D = Elt3where D is the dose;

L is the length hydroponic setup;

t1- move the package of the laser along the hydroponic setup;

- angle of view scanning system (package lasers);

t2the time of rotation of the package lasers in coal ;

El- the intensity of the radiation package laser;

t3- the exposure time (duration of exposure).

In Fig. 2 shows the spectral radiation intensity of the Sun, the lamp and laser. Bundle set of lasers with predetermined spectral ranges that are optimal for specific crops, significantly improves the spectral intensity of the total (natural and artificial) exposure of plants.

Total radiation Eo=E1+ E2+ E3where E1- the intensity of radiation from the Sun;

E2the irradiation intensity of the lamp;

E3- the intensity of radiation from the laser.

The application of the proposed method of growing plants with artificial irradiation of their discharge lamps and scanning lasers in packages that are located in the external and internal zones cenosis, allows to increase the productivity of cultivated crops Pskov integral irradiation (lamp and Sun) and monochromatic radiation (laser).
