Abstract
A technique for culturing the sargassum fursiforme (or Hizikia fursiforme) by use of its pseudorhizae includes such steps as using shearing method to maintain its pseudorhizae, culturing in sea, and collecting the regenerated seedlings for reproduction.
Description
Technical field
The invention belongs to the seed technical field of algae, particularly a kind of Sargassum fusiforme (Harv.) Setch (Sargassum fursiforme=Hizikia fursiforme) rhizoid seed rearing technology.
Technical background
Sargassum fusiforme (Harv.) Setch is the perennial marine alga of warm temperate zone property, and China is coastal widely to distribute, especially with Zhejiang, the coastal growth in Fujian is best, output is high, superior in quality.Sargassum fusiforme (Harv.) Setch is nutritious, and is delicious, is the traditional edible seaweeds of China people.Chinese medicine is called " marine alga ", is one of kind of the early stage Drugdoc record of China.Modern medicine study shows that Sargassum fusiforme (Harv.) Setch all has good food therapy value to control goitre, high blood pressure, elimination brain fag, promotion child development, and being praised highly is one of good health and a long life food.At present, the domestic and international market is in great demand to Sargassum fusiforme (Harv.) Setch, be listed in one of marine alga of up-and-coming foreign exchange earning, utilize Sargassum fusiforme (Harv.) Setch nature seed cultured area to reach more than 400 hectare to China in 1993, caused the nature seed by heavy damage, the solution of artificial seed's technology for this reason, healthy sustainable development is very crucial for the Sargassum fusiforme (Harv.) Setch aquaculture.
Have only the sporophyte stage in the history of life of Sargassum fusiforme (Harv.) Setch, and do not have the tangible gametophyte stage (Ceng Chengkui etc. 1962).Frond is dioecism, different holder, different nest.Discharge from genital fossa after the maturation of ovum and stick to receptacle and wait for fertilization, after fertilization 12-24 days, fertilized egg from receptacle come off from after, attached to carrying out cell division on the rock, form new sporophyte.The fertilized egg in nature marine site is because of being subjected to morning and evening tides and to the selectivity on basis, and it is extremely low to adhere to probability.On the basis by observational study that the Sargassum fusiforme (Harv.) Setch rhizoid is nourished and generated, propose the thinking of " Sargassum fusiforme (Harv.) Setch is nourished and generated based on rhizoid, and sexual reproduction is auxilliary, maintain jointly population in great numbers ", and on rhizoid is nourished and generated, achieve success, can satisfy the production demand.
Summary of the invention
The objective of the invention is to provide a Sargassum fusiforme (Harv.) Setch (Sargassum fursiforme) rhizoid seed rearing technology.At the problem that prior art exists, utilize Sargassum fusiforme (Harv.) Setch biology characteristics, advantage such as the utilization biotechnology is in the rhizoid seedling growing process, and the easy grasp that possesses skills, reduced investment, facility are simple and easy.
Technical scheme of the present invention is to adopt the clip method to keep rhizoid earlier, carries out the sea then and cultivates, and gathers the regeneration seedling as culturing seedling.
Embodiment
1, the clip method is stayed rhizoid: Sargassum fusiforme (Harv.) Setch when results, cut vertical branch more than the base portion with scissors, and keep root and also claim rhizoid, extract large-scale attachment on the seedling rope simultaneously, be a branch of with the 5-10 rope then, the two ends colligation is good.
2, the marine cultivation: the marine site of select that the storm resisting barrier is arranged, trend is unobstructed is provided with to tie up floats the flat rhizoid seedling rope of supporting of formula scaffold, and bundle is cultivated water layer and is controlled in the transparency scope of sea area, with cursory adjusting water layer apart from 20～30cm.Can adopt the centipede frame in mixed water sea area, strut with mao bamboon, the seedling rope fully opens at the water surface.Routine Management to the effect that firmly checks, removes attachment and water layer is regulated.
3, regrowth utilization: cultivate the sea area water temperature autumn when reducing to below 25 ℃ (area, south, Zhejiang is generally early October), the a large amount of generation and ramp of rhizoid regeneration seedling on the seedling rope, can be seedling more than the 2cm when being with a little rhizoid to smooth out with the fingers down to do to culture seedling usefulness, thinning to can continue until 18 ℃ of sea area water temperatures (southern area, Zhejiang is generally in 11 months, the last ten-days period) this moment with length.Also can smooth out with the fingers down whole seedling as big specification regeneration seedling density when big and make seedling usefulness.A common rope rhizoid can divide and support the 2-8 rope.
Claims (4)
1, a kind of Sargassum fusiforme (Harv.) Setch (Sargassum fursiforme=Hizikia fursiforme) seed technology is characterized in that, adopts the clip method to keep rhizoid, carries out the sea then and cultivates, and gathers the regeneration seedling as culturing seedling.
2, according to the described a kind of Sargassum fusiforme (Harv.) Setch seed technology of claim 1, it is characterized in that, Sargassum fusiforme (Harv.) Setch when results, cut vertical branch more than the base portion with scissors, keep root, extract large-scale attachment on the seedling rope simultaneously, be a branch of with the 5-10 rope then, the two ends colligation is good.
3, according to the described a kind of Sargassum fusiforme (Harv.) Setch seed technology of claim 1, it is characterized in that, selection has the unobstructed marine site of storm resisting barrier, trend to be provided with to tie up floats the flat rhizoid seedling rope of supporting of formula scaffold, bundle is apart from 20-30cm, cultivate water layer and be controlled in the transparency scope of sea area, with cursory adjusting water layer, as adopting the centipede frame in mixed water sea area, strut with mao bamboon, the seedling rope fully opens at the water surface.
4, according to the described a kind of Sargassum fusiforme (Harv.) Setch seed technology of claim 1, it is characterized in that, cultivate the sea area water temperature autumn when reducing to below 25 ℃, the a large amount of generation and ramp of rhizoid regeneration seedling on the seedling rope, can be that seedling more than the 2cm is when being with a little rhizoid to smooth out with the fingers down to do breed seedling usefulness, thinning to can continue until 18 ℃ of sea area water temperatures this moment with length.
