Embodiment 1

[0032] A vertical multi-layer cultivating device of long-stem grape fern, comprising a support 1, a culture box 3, multiple sets of light sources 2 and a bracket 6; the support 1 is divided into multiple layers of placement space by a layer board 4. The culturing box 3 is in the shape of an upper open box, and a culturing box 3 is set in the placing space on each layer. Each group of light sources 2 is installed above each layer of culture box 3 to provide light to the culture box 3. The bracket 6 is installed under the bracket 1.

[0033] The breeding box 3 includes a box body, a number of water baffles 10 and an overflow type lower liquid pipe 5; the length of the water baffle 10 is less than the width of the box body, and there is a gap with the side wall of the box body, forming The water outlet; the water baffle 10 is installed in the box body in parallel and spaced staggered to divide the box body into multi-stage water passage; an overflow type lower liquid pipe 5 is prov...

Embodiment 2

[0041] The cultivation method using the vertical multi-layer cultivation device of Botryococcus longiflorum as described in Example 1 mainly includes the following steps:

[0042] (1) Place shell powder, coral stone, volcanic stone or other trace element slow-release fillers in the first-level water passage of each layer of culture box;

[0043] (2) The fish and shrimp farming wastewater is continuously injected into the water inlet of the highest-level culture box, and the salinity of the fish and shrimp farming wastewater is between 30‰ and 32‰; the fish and shrimp farming wastewater is removed by precipitation and filtration Treated with insoluble particles;

[0044] (3) Evenly spread a single layer of long-stem grape pteridophyte species on the lower screen of the double-layer screen, and then buckle the upper layer of the screen to the lower screen to fix the single layer of long-stem grape pteridophyte species;

[0045] (4) Lay the double-layer screen that fixes the single-layer...

Embodiment 3

[0048] A vertical multi-layer cultivating device of long-stem grape fern, which is characterized in that it comprises a bracket 1, a culture box 3, multiple sets of light sources 2 and a bracket 6; the bracket 1 is divided into multiple layers by a layer 4 space. The culturing box 3 is in the shape of an upper open box, and a culturing box 3 is set in the placing space on each layer. Each group of light sources 2 is installed above each layer of culture box 3 to provide light to the culture box 3. The light source 2 includes a fixed board and LED lights; the fixed board is a transparent arc-shaped board; the LED lights are arranged on the fixed board. The bracket 6 is installed under the bracket 1. A universal wheel 7 is arranged under the bracket 6; the universal wheel 7 is symmetrically installed on the lower surface of the bracket 6. A brake plate 8 is also provided on the universal wheel 7. The vertical multi-layer breeding device can be moved as a whole.

Abstract

The invention discloses a vertical-type and multi-layer breeding device for caulerpa lentillifera. The device comprises a support, breeding boxes, multiple groups of light sources and a supporting frame; the support is divided into multiple layers of placing space through layer boards; each breeding box is in the shape of a box which is open at the upper part, and each layer of the placing space is provided with one breeding box; each group of light sources are installed above each layer of the breeding box, the light sources provide illumination for the corresponding breeding box, and the interior of each breeding box is provided with a double-layer screening net; and the supporting frame is installed under the support. The invention discloses a breeding method utilizing the above vertical-type and multi-layer breeding device for the caulerpa lentillifera. The light sources utilized by the device are adjustable artificial light sources, the device does not rely on a natural light source, thus the land resource utilization rate is high; the device can be arranged in a totally-closed breeding workshop, thus totally-artificial control of temperature, illumination and water quality is realized; and influences of factors caused by seasons and climates, such as variation of salinity, temperature and illumination, on the device is small, thus year-round uninterrupted breeding of the caulerpa lentillifera is realized, and balanced marketing of the caulerpa lentillifera is guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a vertical multi-layer culturing device and a cultivating method of the long-stemmed grape pteridophyte. Background technique [0002] Grape Pteridium is a nutrient-rich edible green algae belonging to the Chlorophyta Pteriphyceae. It grows naturally in the Palau Islands and Gigport Islands in the Pacific Ocean with Okinawa as the northern line. The long-stem grape Pteridium algae is called sea grape because of its crystal clear and plump shape like grapes. It is rich in seaweed polysaccharides, collagen and dietary fiber, has a balanced amino acid composition and a complete variety, low fat content and mostly unsaturated fatty acids. Rich in minerals and vitamins, the taste is as rich and juicy as fish roe, and it is also called "green caviar". [0003] Due to the rich nutrition and excellent palatability of the long-stem grape Pteridium algae, the market demand for this algae is ra...
