Russian Federation Patent RU2132119
STIMULATOR SEED GERMINATION
Name of the inventor:
The name of the patentee: Bryansk State Agricultural Academy
Address for correspondence: 243365, Bryansk, Vygonichsky district, pos.Kokino, BSAA.
Starting date of the patent: 1996.04.16
Stimulator allows laser irradiation of seeds and can be used for pre-preparation of large quantities of seeds. An object of the invention is to stimulate the germination of viable seeds in large party by simulating the natural rhythms tsirkodiannyh impact of physical factors necessary during germination particular ecotype plants. The stimulator comprises a laser with a wavelength of 670 and 730 nm. For large mass of irradiation used seed rods made of optical glass having numerous fine inside uniformly distributed inclusions of air bubbles. The rods have a conical shape and equipped with conical inside of the light guide channel optical glass without inclusions of air bubbles. This density allows to evenly distribute the light beam along the length of the rod. Rods of optical glass are inside the irradiated seeds heap. They are connected to a fiber optic laser beam transmission system. The set temperature and the critical seed moisture heap provide ventilation air conditioning.
DESCRIPTION OF THE INVENTION
The invention relates to the field of laser irradiation of seeds and can be used for pre-preparation of large quantities of seeds. Advantageously, the present invention is intended for seed units of agricultural enterprises.
Known industrial plant (Technical Specifications, Lviv, 1978) for the irradiation of seeds coherent monochromatic light 1 Lions "Electronics".
The disadvantage of this setup is a short stay of seeds in the irradiation zone. Short-time exposure to radiation of the seeds with a high density leads to "shock" the stimulation of sprouting seeds partially affecting fitohromnuyu system. Therefore, improving germination and yields seen over the years is unstable.
Construction is known stimulator of seed germination, wherein the impact on seed red light with wavelength 630 - 670 nm is combined with simultaneous exposure to infrared wavelength of maximum absorption of water.
This seed germination stimulant, taken as a prototype, comprises a hopper with loading and unloading system and the laser grain (copyright certificate USSR N 1782384, cl. A 01 C 1/00, publ. 23.12.93).
The disadvantages of this device are low productivity and the prevalence of short-term elements, "shock" stimulate seed germination. Light rays have low physiological activity due to a lack of coherence and monochromaticity. Not used daily spectrometer and termoperiodichnost impact.
Such stimulation repeats the processes occurring in nature that are evolutionarily designed to include physiological mechanisms of seed germination characteristic of ecotype plants.
Poor performance due to the fact that the rays emanating from a point source of radiation, act only on seeds lying on the surface of the mound.
For uniform dispersion of the light beam incoming into the illuminator, you can use a rod of optical glass interspersed with numerous fine air bubbles uniformly distributed (Russian Federation patent N 2003149, cl. G 02 B 27/48, 15.11.93).
This device is capable of irradiating the seeds lying on the surface of the mound. The length of the surface area of one rod of optical glass is too small to irradiate light scattered all the seeds inside a large heap.
An object of the invention is a stimulation to germinate all viable seeds in a large party, by simulating natural rhythms tsirkodiannyh impact of physical factors necessary during germination particular ecotype plants.
This object is achieved in that the seeds are subjected to prolonged stimulant effects on the embryos system fitohromnye coherent monochromatic beams of wavelength 670 or 730 nm. At the same time maintained the required temperature and the critical seed moisture. Object of the invention is provided in that the device comprises a laser with a wavelength of 670 and 730 nm. For the purpose of long-term irradiation of large mass of seeds used optical glass rods having inside multiple fine, uniformly distributed inclusions and air bubbles used in the invention patent N 2003149. The device comprises a large number of rods. They have a conical shape, and characterized by having light transmission channel in the conical optical glass without inclusions of air bubbles. This density allows to evenly distribute the light beam along the length of the rod.
In the proposed device, the rod of optical glass are inside the irradiated seeds heap. They are connected to a fiber optic laser beam transmission system. The set temperature and the critical seed moisture is provided by ventilated heap air conditioning.
Comparative analysis of the prototype shows that the proposed stimulator is characterized in that large batches of seeds are irradiated for a long time physiologically active light introduced via the inside heap seed rods made of optical glass at a predetermined temperature and humidity. The device allows you to reproduce the natural rhythm tsirkodiannuyu impact of physical factors on seeds, appropriate to their ecotype. Thus, the claimed invention meets the criterion of a stimulator of "novelty".

FIG. 1 shows a hopper aeration and irradiation of seeds and FIG. 2 - its cut. The rod of optical glass interspersed with numerous fine bubbles having a tapered light guide channel, without bubbles, shown in FIG. 3 and FIG. 4 and 5 - sectional view of FIG. 3 A-A and B-B.
The device comprises a hopper 1 active aeration of grain included in the bunkers of active aeration system, equipped with loading and unloading of grain system, the air conditioner 2, the system of waveguides and splitters 3, rods made of optical glass blocks 4 lasers with a wavelength of 670 nm and 730 - 5 and 6 and the switch 7 respectively for connection to the laser units.
The rod 4 of the optical glass used in the device comprises a waveguide 3, extender switch the optical beam 8 of the core of the optical glass without inclusions of air bubbles 9 and the optical window with multiple finely divided uniformly distributed over the volume inclusions of air bubbles 10, ending at the end of the mirror reflective coating eleven.
Stimulator operates FOLLOWS
Hopper 1 is fully or partially loaded with seeds 12 in the usual way download. With the switch 7 connects to an optical system laser unit 5, 6 with the required wavelength. Suitable for ecotype plants and the temperature of the critical seed moisture is maintained by an air conditioner. For uniform irradiation of all seeds produce their slow recirculation in the hopper 1.
inside heap seed irradiation allows dozens of times to increase the plant capacity for long-term effects on seeds by three environmental factors (light, water and temperature). This is easily accomplished daily and spectro- termoperiodichnost impact.
The unit can be used for large quantities of seed vernalization; to improve vigor, laboratory and field germination of seeds of plants ecotypes that require special conditions of inclusion of the physiological mechanism of germination; for "education" in the seeds, and through them in future plants neutral relationship to the length of the day and quality of natural light, and acceleration and phasic development of plants.
