Date of commencement of the patent: 1993.01.20
Use: agriculture, in particular, when growing vegetables on hydroponics. SUMMARY OF THE INVENTION: The growing method includes watering plants, lighting, temperature control. In this case, the temperature regulation is carried out according to a sinusoidal regularity with an oscillation period of 0.5-20 min and an amplitude of 10-0.5 ° C. Moreover, the preferred control mode is a 2-5 min oscillation period with an amplitude of 2-5 ° C.
DESCRIPTION OF THE INVENTION
The invention relates to agriculture, in particular to the production of vegetables in sheltered soil, greenhouses with hydroponic technology with artificial lighting.
A method for growing plants in greenhouses on multi-tiered hydroponic installations with artificial lighting is known (Greenhouse Project 1190 m 2 with a multi-level narrow-columned hydroponic technology at the Prigorodny state farm in Syktyvkar, Orel, Giproniselprom, 1989).
The disadvantage of this method is the low crop yield of cultivated crops due to the uneven distribution of heat in the greenhouse along the height of the plants.
The task was set to create a method of growing plants, which achieves the optimum temperature regime, which will affect the yield.
The proposed solution solved the problem of regulation and selection of the optimal temperature regime in the cenosis, which stimulates the growth of plants of cucumbers, tomatoes and, consequently, shortens the period of vegetation and raises the yield.
In the method of growing cucumbers and tomatoes in a hydroponic greenhouse, including irrigation, lighting, temperature control. According to the invention, the temperature control is performed according to a sinusoidal law with an oscillation period of 0.5-20 minutes and an amplitude of 10-0.5 ° C.
Preferably, the temperature control is performed with an oscillation period of 2-5 minutes and an amplitude of 2-5 ° C.
The claimed invention makes it possible to achieve the following technical result.
Regulation of the temperature according to a sinusoidal law with a period of oscillations equal to 0.5-20 min and an amplitude of 10-0.5 ° C will make it possible to select the optimum temperature regime at which the growth and accumulation of the crop occurs quite intensively and, consequently, increases the yield.
The claimed method for cultivating cucumbers and tomatoes in a hydroponic greenhouse, including irrigation, lighting, temperature control, differs from the known method adopted for a prototype in that the temperature control is performed according to a sinusoidal law with an oscillation period of 0.5-20 min and an amplitude 10-0.5 ° C.
Comparable analysis of the claimed solution with the well-known, taken for the prototype, allows to make a conclusion that the proposed technical solution satisfies the inventions "novelty".
It is not known from the patent and scientific and technical literature for a person skilled in the art that the temperature control is performed according to a sinusoidal law with a period of oscillations of 0.5-20 minutes and an amplitude of 10-0.5 ° C, which makes it possible to achieve the effect described above.
Thus, the proposed solution satisfies the criterion of the invention "inventive level".
The claimed technical solution can be used in agriculture, it allows you to select the optimal temperature regime in the greenhouse, and therefore, to stimulate plant growth and increase yield.
Thus, the proposed solution satisfies the criterion of "industrial applicability".
The method is explained in the drawing, where the chart shows the course of the change in the temperature of the deciduous cover. As a result of scientific and experimental studies, the regularity of the change in the temperature of the deciduous cover of plants in time was determined depending on the intensity of irradiation and air temperature in the greenhouse, which obeys a sinusoidal law: as the irradiance and air temperature increase, the period of temperature oscillations increases and the amplitude decreases. This is due to the fact that in the initial period the leaf temperature rises to a certain maximum of the vertex of the sinusoidal curve, and then falls due to the evaporation of moisture by the surface of the sheet.

Curve 1 shows the change in the temperature of the deciduous cover at an irradiation intensity of E 1 and an air temperature of 20-22 ° C. The temperature changes with an oscillation period of about 5 minutes and an amplitude of -2 ° C. On curve 2, at an irradiation intensity of E 2, the oscillation period is about 2.5 minutes, the amplitude is 3 ° C., at an air temperature of 23-26 ° C. According to curve 3 at an irradiation intensity of E 3 at an air temperature of 26-30 ° C., About 1-1.5 minutes and an amplitude of 4 ° C., and along curve 4 at an irradiation intensity of E 4 and a temperature of 28-33 ° C., the oscillation period is about 1 min and the amplitude is 5 ° C. Method of growing cucumbers and tomatoes in a hydroponic greenhouse, adjusting the temperature in the volume of the greenhouse, taking into account the temperature of the foliar cover (cenosis) according to the sinusoidal law with an oscillation period of 0.5-20 min and an amplitude of 10-0.5 ° C. |
A specific example of the method:
In the greenhouse, the temperature was regulated with a period of oscillations of 2-5 min and an amplitude of 2-5 ° C gave an increase in yield to 5-7% and energy savings.
Application of the method of growing cucumbers and tomatoes by adjusting the temperature in the greenhouse according to the sinusoidal law with the established period and amplitude of the oscillations will allow increasing the yield by 5-7% due to the selection of the optimal temperature regime.
