Summary: Hydroponics is a perspective direction of development of modern agriculture that provides perennial growing of main species of vegetables and greenery on small areas and with minimal expenses of water and fertilizers. This technology allows to get large enough harvests of fresh vegetables in big cities including office and living premises.
Last time entrepreneurs and inventors pay a lot of attention for elaboration of more effective methods of hydroponics and equipment for their realization in direction of decrease of using areas, economy of water, nutrients and increase of air supply and plants capacity.
There are several known methods of hydroponics: static solution culture, continuous-flow solution culture (NFT), deep water culture, passive sub-irrigation, flood and drain sub-irrigation, run-to-waste system, top-fed deep water culture, rotary system, aeroponics, fogponics. Commercial and industrial use got the first three from above mentioned methods. Herewith the method of static solution culture does not provide of necessary saturation of plant’s roots with air. Under realization of the method of continuous-flow solution culture are possible little buffering against interruptions in the flow (power outages), water logging in some channels, besides there are limitations for maximal length of channels (12 – 15 m). The method of deep water culture in industrial scales is used mainly for growing of lettuce. The other mentioned methods are not enough effective from point of view of commercial utilization.
The improved hydroponic installations, presented in the article, were elaborated with consideration of such demands: versatility of use (a possibility of growing of various species of plants); harmonies optimal provision of crops with water, nutrients, light and air; maximal use of premise’s space; a possibility of re-space during of the growth period, increase of area for each plant and support of its stalk and sprouts. Also, the formulas for definition of main parameters of the elaborated installations are presented in the article.
