A plant for ozonation of seeds contains a treatment chamber made of a sealed box with a lid, inside of which there is an ozone generator with a gas pipeline, a device for placing seeds in the form of separate removable containers, a sensor that transmits a signal about ozone concentration to a control unit located outside the processing chamber. On both sides of the processing chamber there is an ozone-air mixture discharge device and an air intake device. The latter is connected to a fan.

The claimed installation for ozonation of seeds is of interest to the national economy, as it reduces the duration of seed treatment and eliminates the need for heating after cryogenic treatment with liquid nitrogen, while the quality and effectiveness of seed treatment, increasing their germination, are not reduced.

Description

The utility model relates to the field of agriculture, namely, to stimulate seed germination, increase the biomass growth rate, and can be used in crop production, vegetable growing, fruit growing, green building, and forestry.

A known installation for pre-sowing seed treatment (SU No. 1160959, IPC A01C 1/00, publ. 30.08.1992), containing a hopper for seeds, treatment chambers, conveyors with cells for seeds, a tape and a device in the form of a sprayer for seed treatment.

The closest in technical essence and the achieved effect is the installation for cryogenic stimulation of germination of plant seeds (RF Patent No. 174306, IPC А01С 1/00, published October 11, 2017), containing a processing chamber, a device for placing seeds, and a processing chamber made in the form of a sealed box with insulated walls and a lid, and a device for placing seeds - in the form of separate removable containers. On the box lid, a loading through hole was made for supplying liquid nitrogen to the chamber, which was closed by a removable plug. The inner part of the box is divided by means of perforated walls into separate cells with temperature sensors into which containers for seeds are loaded. In addition, each container is equipped with a top handle to facilitate placement and removal from the cells, and chromel-aluminum thermocouples that are connected to a common control unit can be used as temperature sensors.

The disadvantage of the analogue and prototype is the use of cryogenic seed treatment with nitrogen, in which it is necessary to process the seeds for a long time (up to several days), and then heat them for a long time (up to a day).

The objective of this utility model is to develop a plant in which seeds are treated with an ozone-air mixture, which will reduce the duration of seed treatment and eliminate the need for heating them after cryogenic treatment with liquid nitrogen, while the quality and effectiveness of seed treatment that increase their germination are not reduced.

This object is achieved in that the installation for ozonation of seeds, consisting of a processing chamber made of a sealed box with a lid, inside which there is a device for placing seeds in the form of separate removable containers and a sensor, a control unit located outside the processing chamber, in contrast from the prototype for ozonation of seeds inside the processing chamber, an ozone generator with a gas pipeline, a sensor transmitting a signal of ozone concentration to the control unit are installed, while the camera for processing aschena device release ozone-air mixture, and air inlet device, the latter is connected to a fan for accelerating the reduction of the ozone concentration in the process chamber.

The technical result of the developed installation for ozonation of seeds is to reduce the duration of seed treatment and eliminating the need for heating the seeds after cryogenic treatment with liquid nitrogen, which is achieved by the fact that the seed treatment is due to the use of ozone-air mixture, while the quality and efficiency of seed treatment, increasing their germination are not reduced. In addition, the simplicity and compactness of the installation, the ability to monitor changes in the concentration of ozone in the seed treatment chamber under stationary conditions make it possible to use it for scientific purposes as a laboratory installation.

In FIG. 1 shows a plant for ozonation of seeds. In FIG. 2 shows a graph of the change in the percentage of germination of seeds depending on the time of processing.

The installation (Fig. 1) consists of a processing chamber 7 made of an airtight box with a cover 4, an ozone generator 2 with a gas pipeline 3, a device for placing seeds in the form of separate removable containers 9, a sensor 8 transmitting a signal about ozone concentration are located inside the chamber on the control unit located outside the processing chamber 1. On both sides of the processing chamber 7 there is an ozone-air mixture discharge device 10 and an air intake device 6 connected to the fan 5. As devices 10 and 6, it is possible to use tiley.

Installation for ozonation of seeds works as follows. Seeds in separate removable containers 9 are installed in the processing chamber 7 and hermetically closed by a cover 4. Next, the ozone generator 2 is turned on, and the ozone-air mixture is supplied through the gas pipe 3 to the processing chamber 7, while the air intake device 6 must be closed and the device 10 release of the ozone-air mixture - open. The supplied ozone-air mixture displaces air from the treatment chamber 7 into the atmosphere through the ozone-air mixture discharge device 10, increasing the ozone concentration in the treatment chamber 7. From the sensor 8 installed in the chamber 7 for processing the sensor 8, a signal about the ozone concentration is transmitted to the control unit 1, and when the required ozone concentration is reached, the ozone-air mixture discharge device 10 is closed. At the end of the ozonation of seeds in order to purge the treatment chamber 7, the ozone-air mixture discharge device 10 and the air intake device 6 are opened. In this case, to speed up the air supply and more quickly reduce the concentration of ozone in the treatment chamber 7, the fan 5 is turned on. After reaching the maximum permissible concentration of ozone, the lid 4 opens, and the seeds are removed from the treatment chamber 7.

Table 1 shows the results of the effect of ozonation on seed germination and the rate of development of zucchini zucchini seedlings of the Zebra variety at an ozone concentration of 9 mg / m ³ . The highest seed germination is observed in the case of seed treatment with ozone for 240 minutes. This processing time also affects the growth rate of biomass. Seeds treated in this way have the highest values of the average height of the seedlings and the average width of the leaf plate for 10 days.

For scientific purposes, to obtain experimental data, you can build a graph of the change in the percentage of germination of seeds depending on the time of processing (Fig. 2).

The use of a plant for ozonation of seeds reduces the duration of seed treatment and eliminates the need for heating of the seeds after cryogenic treatment with liquid nitrogen. At the same time, the quality and effectiveness of seed treatment, increasing their germination, are not reduced.
