A double-sided light-receiving culture floating bed for long-stem grape fern algae and its culture method

Abstract

The invention provides a caulerpa lentillifera double-sided light-receiving culture floating bed and culture method and belongs to the field of seawater algae culture. The culture floating bed includes a frame, a mesh, diving lamps, a sling and an elastic bar, wherein the frame is a saddle type and includes a frame top, a left side and a right side, and the frame is made of a hollow pipe and the pipe connecting fitting which are spliced. The floating bed is advantaged in that the floating bed is utilized for culturing the caulerpa lentillifera, the artificial light at the lower layer of the floating bed is controlled by combination of different light-quality diving lamps, the floating bed depth and the sunshade mesh are adjusted to control the natural light of an upper layer of the floating bed, rapid production of new algae on upper and lower sides of the caulerpa lentillifera culture floating bed is promoted, the growth rate of the caulerpa lentillifera is accelerated, and the biomass and the yield are enhanced.

Description

technical field [0001] The invention belongs to the field of seawater algae culture, and in particular relates to a double-sided light-receiving culture floating bed and a culture method of long-stem grape fern algae. Background technique [0002] Caulerpa lentillifera, commonly known as "sea grape", is a newly cultivated tropical rare green algae, which has high nutritional value and health benefits, and has a huge market potential. The large-scale cultivation of Botrytis elongatus originated in Japan (1985). Its main production area is Okinawa. The cultivation method is mainly in the land greenhouse combined with deep ocean water. The annual output is about 600 tons, and the retail price in Japan is about 100 tons. RMB 700 / kg. At present, Vietnam is the main producer of Botrytis longstem in the world (beginning in 2004). Its breeding method is mainly pond culture, with a total annual output of 6,000-9,000 tons. Most of them are exported to Japan, Europe and the United Sta...

Problems solved by technology

In recent years, domestic research on the cultivation of V. long-stemmed fern is in the ascendant, and the scale of domestic cultivation is far from industrialization. There are many constraints, such as: 1) The price of the long-stem V. long-stem product is high and the domestic demand is not enough. Big

2) Domestic production costs are relatively high (including the cost of building workshops, purchasing long-stem grape fern algae, winter heating, labor costs, etc.)

3) The domestic industrial culture technology of Vitis vinifera is immature, resulting in low overall yield, unstable yield and poor product quality
