FIELD: equipment for growing plant tissues.

SUBSTANCE: in accordance to the invention, unit for accelerating growth of plant tissues contains a set of boards, forming matrices of holes. Each hole contains a tissue sample. Support for boards is provided by a rack which contains a set of vertically stacked shelves, containing one or more holding recesses, which forcedly move boards to given positions. Light for tissue samples is provided by a set of matrices of light diodes, mounted on mounting plates. Light diodes emit white light. Each mounting plate is supported by corresponding end comber-type rack connector, so that light diodes are close to boards, supported by shelves, positioned lower. Matrix of light diodes preferably matches matrix of holes, supported by a lower positioned shelf in fixed position, so that each light diode is centered above a corresponding hole.

EFFECT: creation of high capacity system for processing samples of tissues which require light for supporting cell reproduction.

FIELD: microbiological industry; equipment for growing of microseaweeds.

SUBSTANCE: the invention is pertaining to microbiological industry, to the equipment for growing of microseaweeds, in particular, to the installation for growing of a chlorella. The installation for growing of microseaweeds, in particular, a chlorella includes a capacity located on a skeleton used for suspension of microseaweeds, in which there are the upright mounted cylindrical glass shells with the stationary placed in them electric bulbs. The capacity is supplied with the fans, installed under the shells and used for the air supply inside the shells at the moment the temperature of the suspension exceeds the optimal temperature of the cultivation. The installation is supplied with a suspension temperature detector located inside the capacity connected with a temperature controller connected to the fans. The invention ensures a reliable control over the temperature during cultivation of microseaweeds and keeping the temperature within the optimal limits for raising the productivity of the installation.

SUBSTANCE: method provides stocking with fish the pond with herbivorous fishes, namely, white and particolored silver carps and addition of the microalgae suspension to the pond (algolization). Method involves using suspension of chlorella of the strain Chlorella vulgaris BIN in the cell density 50-60 x 106 cells/ml in the amount 20-40 l. The suspension is added in 2-4 points in upper and median parts of the pond and for enhancing the effect the pond is stocked with fish with herbivorous fishes, namely, two-aged white and parti-colored silver carps in the amount 1-10 fishes per ha. The proposed protection method of pond prevents water "flowering" with blue-green algae and creates the favorable ecological situation.
