Abstract
The present invention relates to seedlings raising technology for seaweed, especially relates to a artificial seedlings raising technology for rattailed algae, comprising breeding and gathering colza, discharging and fecundating of sperms and germ cell, gathering oosperms, cultivating sprout inside indoor, temporarily breeding sprout on the sea, after flatly breeding on a catamaran 30-40 days, could reach length of 2-3cm, density of 8-10 plants each centimeter. The present invention could obtain stable yield and could produce two crops a year.
Description
Technical field:
The present invention relates to the marine alga seedling growing process, specifically a kind of full artificial seedling nursing technology for sargassum thunbergii.
Background technology:
Mouse tail algae (Sargassum thunbergii) is a kind of in the brown alga, is warm temperate zone property marine alga.Mainly be distributed on the reef of intertidal zone the fresh and tender softness of its blade, nutritious at natural world.According to one's analysis, mouse tail algae contains crude protein 14.4%, crude fat 0.31%, total reducing sugar 57.0%, raw fiber 4.4%, ash content 23.4%; Essential amino acid, unsaturated fatty acid and mineral matter and content of elements are abundant and reasonable.(brightness three rises abruptly: algae is integrated the history of life) mouse tail algae also has the effect that expeling colonizes in the roundworm in the human body according to another report, as famous ascarifuge marine alga---Zhegucai can be made pest repellant.With the mouse tail algae powder young ginseng of throwing something and feeding, or serve as throw something and feed young ginseng and become ginseng of the main manufactured feed made from mouse tail algae powder, its digestion is fast, absorption rate height, and owing to mouse tail algae phycocolloid content is very low, thereby its to grind liquid seldom mucous, so polluted water not.From report of mouse tail algae analysis of components that the researcher did and vast breed dealer breed experience for many years, mouse tail algae be the sea cucumber artificial breeding and propagate artificially in best natural feed.Rely on fully at present and gather wild resource, along with the continuous intensification of holothruian cultures, to the increase day by day of mouse tail algae demand, wild resource amount limited amount did not only satisfy the needs that sea cucumber is grown seedlings and cultures, and yet rising all the way of price in recent years.Some places mouse tail algae resource is closely exhausted, and the required mouse tail algae feed of sea cucumber large-scale farming has very big breach.Regardless of the demand that already develops from holothruian cultures mouse tail algae, still protect the wild resource of mouse tail algae, the artificial breeding of carrying out mouse tail algae is imperative.
Summary of the invention:
The purpose of this invention is to provide the full artificial seedling nursing technology for sargassum thunbergii that a kind of technology is simple, seedling cost is low, shoot survival percent is high, the cultivation seedling time is short.
The present invention can reach by following measure:
A kind of full artificial seedling nursing technology for sargassum thunbergii, the condition of its processing step is:
(1) plant vegetables and cultivate to collect: adopt the raft formula flat hanging at sea, put 10000 strains that plant vegetables～20000 strains in a suitable place to breed for every mu, culture water layer 30cm～50cm, cultivate target and be receptacle and reach full growth and reach sexual maturity,
(2) discharging of sperm and ovum and fertilization: plant vegetables through 1 hour～2 hours dry in the shade stimulation, promote mouse tail algae to plant vegetables, the discharging of sperm and ovum, the ♀ strain that plants vegetables is 1: 1 with ♂ strain ratio, put into the seawater pond and adopt fertilized egg, adopt in the fertilized egg process, constantly stir seawater, impel diffusing and being fertilized of ovum, dry in the shade stimulation is meant under the dehydration lucifuge condition stimulates mouse tail algae to plant vegetables, promote mouse tail algae to plant vegetables the discharging of sperm and ovum
(3) gather fertilized egg: adopt the seedling curtain to gather fertilized egg, useful chemical fibre cloth, reddish brown rope or vinylon rope are made, specification is 0.75m * 1.00m, fertilized egg adhering on the seedling curtain, adopt the hydrostatic fertilized egg method of splashing, can improve the adhesion amount of fertilized egg, adhere to 12 hours～15 hours time, adhere to density under 10 * 10 low power lens, 20～30 fertilized eggs in every visual field
(4) indoor seedling culture: intensity of illumination 4000lx～8000lx, at 10 hours～14 hours at sunshine; Nutritive salt NO in the control seedling water
3 --N (2～5) * 10
-7, PO
4 3--P (0.2～0.5) * 10
-722 ℃～27 ℃ of water temperatures; 2～4/day of the water yields, the time is 30-50 days,
(5) marine temporary culture of seedling: adopt the raft formula flat foster, just can reach the long 2cm～3cm of body through 30～40 days marine supporting temporarily, density is the commercial seedling of 8 strains～10 strains/cm.
The present invention adopts present technique can guarantee that commercial seedling production accomplishes stable yields, has that technology is simple, seedling cost is low, shoot survival percent is high, cultivates and can culture advantages such as two batches short, every year seedling time.
Embodiment:
Below the present invention is further described:
