The way the plants dosvechivaniya

 

(57) Abstract:

Usage: agriculture , field crop production in buildings protected ground. The inventive method of dosvechivaniya plants in the greenhouse at the location of the growing trays triangular frames includes specifying the duration of artificial irradiation and switching sections of the radiation sources, in this section of the radiation sources are divided into n groups with equal number of sources, assign each section of the springs and frame numbers, then turn on 8-15 hours include sources of radiation from the first to n-th group, located above the trays frames with odd or even numbers, then shut down the section of the light sources and include sources with the same group numbers over the frames with odd or even numbers on 8-15 hours then these techniques are cyclically repeated. The use of the invention improves the yield of the crops produced by 5-8%, and also reduce the power irradiators, to increase the service life of the light sources. 5 Il.

The invention relates to methods of dosvechivaniya plants and can be used in agriculture in greenhouses.

The need to periodically turn on and off light sources to create the normal development of plants in the known method requires the inclusion of all light sources, and this complicates the operation of the greenhouse, as it requires the creation of a powerful lines for supplying power to the sources of optical radiation, which leads to an overload of supply substations. Work on the limit leads to instability of the supply voltage, and hence instability of the spectrum of optical radiation, which reduces productivity and leads to premature exit of the light sources fails, the irregularity of their life.

The task was to reduce power consumption, to increase the yield in the greenhouse due to the stabilization of the emission spectrum, increasing RA is the way dosvechivaniya plants, grown in greenhouses at the location of the growing trays triangular frames established by the series, including long cycle of artificial irradiation plants and in accordance with the latest switching sections sources of optical radiation, is placed over the growing trays each frame according to the invention the section of the optical sources are divided into n groups with equal number of sources, assign each partition of radiation sources and frame numbers, then include alternately in 8-15 hours of the radiation sources from the first to n-th group, located above the growing trays frames with odd or even numbers, then in the same order off the section of radiation sources with the same group numbers over the frames with odd or even numbers on 8-15 hours, and these techniques are cyclically repeated.

In Fig. 1 shows a plant for hydroponic cultivation of cucumbers; Fig. 2 electrical circuit for controlling the radiation source of Fig. 3 and 4 are examples of the operation of the irradiation system of Fig. 5 examples section numbering radiation and frameworks installation.

Greenhouse tools vegetation the district trays 2 for cucumbers 3. Over the growing trays 2 each of the frame 1 on the supports 5 are grouped in the section sources of optical radiation 4, provided with a light reflector 6 and 10. The number of radiation sources 5 in each group and on each frame 1 in the same way.

The operation of the lamps 4 is controlled by control Cabinet 7 through the block 8 and the supply line 9. The numbers "1", "2" and "3" shown in the wiring diagrams of pairs of lamps 4, is placed over one of the vegetation block frame 1. Positions 1', 2', 3', 4', 5', 6', 7', 8', 9', 10', 11', 12', 13' and 14' shows the numbering of the frames 1 hydroponic setup. Sign*shows the even-numbered frames 1. Position 11 marked the fence greenhouse.

Way dosvechivaniya plants in the greenhouse for hydroponics is as follows.

Planted in trays 2 seedlings of cucumbers 3 in addition to the natural light available is irradiated with artificial light lamps 4. To create the optimum for plant length mode spectral composition of the flows of radiation are assigned the same and is determined by calculation on the uniformity of exposure of at least one stage lamps. The basis of the division of radiation sources 4 groups based on the principle of obtaining uniform exposure about the connectivity and off controlled by control Cabinet 7 and section block 8 in the control Cabinet. According to the schedule system to irradiation (Fig. 3 and 4) lamp irradiation 4 alternately include 8 to 15 hours. Experimentally proved rationally to include 11 13 hours, almost breaking the day into 2 parts.

Lamps include pairs of 3", 2" and 1". After a specified period of exposure of a particular program, the slots of the lamps 3", 2" and 1", mounted on frames with clear numbering, include and hide the corresponding pair of lamps over 4 frames 1 with odd numbering (Fig. 2). Then this technique is cyclically repeated.

The spectral composition of the light flux of radiation sources selected for the culture of cucumber and generally the same. If necessary, growing different crops in the same volume can be different and depends on the specific culture.

The application of the proposed method, dosvechivaniya plants in a greenhouse allows you to reduce power consumption irradiators, to increase the uniformity and durability of the light sources, to increase the yield of cucumbers 5 8%

Way dosvechivaniya plants grown in greenhouses at the location of the growing trays triangular frames established by the series, including for the sources of optical radiation, posted by over the growing trays each frame and including an equal number of sources, wherein each partition of the source of optical radiation is assigned a corresponding sequence number, the source of optical radiation of each section are divided into n groups including the same number of sources and having a corresponding numerical index and the duration of the cycle of artificial irradiation plants set within 8-15 h, while in the first cycle of irradiation, the switching sections of the optical sources is carried out by sequential inclusion in ascending numerical index of all groups of sources of optical radiation, respectively, all even-numbered or odd-numbered sections, and in all following cycles of irradiation by successive off in reverse order of the above sections of optical sources and simultaneous switching alternately in ascending numerical indexes all off in the previous cycle sections of optical sources.
