Abstract

FIELD: plant growing. SUBSTANCE: method involves placing plants on substrate arranged on vegetative dams constructed on water of basin stocked with fish in spaced relation with respect to water surface; providing cyclic agitation of bottom slit under dams during growing period. Vegetative apparatus has frame and floats defining dam, trays having perforated bottom and filled with nutrient substrate. Wicks are positioned in trays. Apparatus is further equipped with slit agitating devices mounted on frame vertically with respect to its surface, in the vicinity of floats. Agitating devices may be formed as rods with lower part formed as inverted funnel. EFFECT: increased efficiency, simplified construction of apparatus and improved operation conditions. 4 cl, 1 dwg

Description

 The invention relates to the field of crop production and can be used for hydroponic cultivation of plants.

 A known method of hydroponic cultivation of plants, including placing plants on a substrate located on vegetation rafts installed with a gap relative to the surface of the water on a stocked reservoir (A. Frolova. Vegetation rafts - greenhouses without heating. Inventor and rationalizer, 7, 1985, pg. 8-9). The disadvantage of this method is its complexity, caused by the content of fish in special cages under the vegetation device.

 The closest in its technical essence is the method of hydroponic cultivation of plants, including placing plants on vegetation rafts installed with a gap in relation to the surface of the water on a stocked reservoir (ed. St. USSR 969208, class A 01 G 31/00).

 The disadvantage of this method is the difficulty in retaining fish in the area of the vegetation raft, which affects the amount of waste products emitted by it in this area, which are the best fertilizer for growing plants.

 A vegetation device is known that contains a frame forming a raft with floats (ed. St. USSR 969208, class A 01 G 31/00). The disadvantage of this device is the great complexity of the design.

 The closest in technical essence is a device containing a frame and floats forming a raft, trays with a nutrient substrate and wicks, having a perforated bottom (A. Frolova. Vegetation rafts - greenhouses without heating. Inventor and rationalizer, 7, 1985, pp. . 8-9).

 The disadvantage of this device is its complexity and inconvenience of operation, caused by the presence in it of a fish tank attached to the frame. Periodically, it is necessary to monitor the condition of the fish in the cage, for which it is necessary to turn or raise the raft.

 The objective of the present invention is to simplify the design and improve its operating conditions.

 The present problem is solved by the fact that in the method of hydroponic cultivation of plants, including placing plants on a substrate located on vegetation rafts mounted on the water of a stocked reservoir, with a gap with respect to its surface, during the vegetation period of plants under the rafts, cyclic induction of bottom silt is performed.

 The present problem is solved in that the growing device, including a frame and floats forming a raft, trays with a nutrient substrate and wicks having a perforated bottom, additionally contains sludge activators.

 The exciters are mounted on the frame, vertically on its surface, from the side of the floats.

 The excipients are made in the form of a rod, the lower part of which looks like an inverted funnel.

 The drawing shows a vegetation device.

 The device consists of a frame 1, forming a raft with floats 2, on which there are trays 3 with a nutrient substrate 4. The trays 3 have a perforated bottom 5 through which wicks are lowered 6. On the frame 1 from the floats 2 are installed silt activators 7, bottom 8 some of which are made in the form of an inverted funnel.

 The method is as follows. The seeds of cultivated plants are planted in nutrient substrate 4. Wicks dipped into water 6, by their capillaries, draw moisture and wet the substrate. Plant seeds germinate, their roots exit through the perforated bottom 5 and fall into the water, from where nutrients are taken. After that, the wicks are removed.

 To increase the amount of nutrients in the water, fish are lured into the area of the raft, since the fish vital products are the best fertilizer. For the greatest accumulation of fish in the area of the raft on the frame 1 from the side of the floats 2 install sludge activators 7. The lower part 8 of sludge activators 7 is made in the form of an inverted funnel. The terminals of the silt activators 7 when the water is agitated due to mechanical entry into the bottom sludge or exposure to it with a stream of water created by the funnel-shaped end 8, wash out water microorganisms from the sludge, which attract fish and force them to be constantly located in this zone.
