Sargassum fusifome sporinite, which is dredged to keep hanging, to be grown and field management, the harvesting of sargassum fusifome maturation sporinite and field management, the specific steps are as follows:
1) picking of sargassum fusifome seed or seed breeding
A. sargassum fusifome fish wild seed is picked
Artificial acquisition immediate offshore area island or islands and reefs low tide are dwelt with the sheep that the length grown naturally on reef is 5cm-15cm
Dish juvenile sporophyte, naturally wild seed can be not only used for propagating artificially on a large scale, can be used for the sections such as breeding purifying, breeding cross
Grind work.The optimal acquisition time of the naturally wild seedling of sargassum fusifome is annual September part to November；
B. sargassum fusifome vegetative propagation seed breeds
Sargassum fusifome vegetative propagation habit is manually utilized, remaining rhizoid after mature sporinite harvest is remained in into Miao Shengshang,
It is cultivated 120 days or so through natural waters, cultivation period is annual first arrival in May August end, obtains the young spore being divided by rhizoid
Body；
C. sargassum fusifome sexual propagation seed breeding
Sargassum fusifome sexual propagation habit is manually utilized, the fertilized eggs of concentrated collection are uniformly sprayed to seedling curtain, 5 in Miao Chi
It -7 days cultivate and natural waters cultivate 120 days or so, obtain by development of fertilized ova at juvenile sporophyte；
2) sargassum fusifome artificial seed cultivation and field management
A. seed and field management manually are cultivated using sargassum fusifome vegetative propagation
Picking time in May is reserved by the seedling rope (diameter 0.5cm) with sargassum fusifome rhizoid, set natural waters cultivation 4-5
A month, until month current year 9-10, the juvenile sporophyte that rhizoid is developed into through vegetative propagation on seedling attaching rope was manually to utilize sargassum fusifome
The seed that vegetative propagation is cultivated, nurturing period should complete following field management operation:
1. selection keeps hanging raft frame: " soft buoyant raft raft frame " or " centipede frame ", attached drawing 2- attached drawing 3 take close extension cultivation method (every
Four seedling ropes are a step), step spacing keeps 20cm-25cm；
2. sea area selects: seawater mean temperature is less than 27 DEG C between selecting annual August-September, ocean temperature holding higher than 27 DEG C
Continue the time less than 7 days；
3. environmental factor: the environmental factors such as periodic monitoring ocean temperature, salinity, pH value and intensity of illumination make a record；It is close
The casting of concern Typhoon Information and the variation of harmful organisms population quantity are cut, carries out reply outburst surroundings factor variations measure in time；
4. daily management: it inspects periodically raft erection and applies, discovery is damaged or floating material is hung etc., it to repair or extract in time,
Meanwhile safety sign is set up in time, warning passing ships evacuation navigation；
5. keeping hanging natural waters initial stage, need to check embryo development situation daily, if discovery media surface sedimentation silt or
Sundries blocks, and removes silt or sundries by craft or giant in time；
B. seed and field management manually are cultivated using sargassum fusifome sexual propagation

It hangs holding culture offshore -30 days 20 days, then carries out dredging to keep hanging growing；It presss from both sides seedling initial stage, the folder seedling rope on direct sandwiched diameter 0.5cm seedling rope,
It directly carries out dredging to keep hanging growing；The smaller sea area of stormy waves, Dan Shengping are hung, and single folder seedling rope both ends hang " navigation channel rope " correspondence respectively and " hang
On rope "；The larger sea area of stormy waves is hung using duplex type is flat, and with two folder seedling ropes for a step, both ends hang the corresponding lanyard of navigation channel rope respectively
On；More than 50 extra large mus the people are supported in cultivation face, and 1/3 cultured area of planning takes every two step to press from both sides the hanging method that Miao Shengkong stays a step seedling rope
It is divided into seedlings, suspension raft frame reduces for harvesting later period harvesting and causes rotten dish degree because rainfall is excessive；Using centipede rack device
Cultivation hangs cultivation method only with Dan Shengping；
B. field management
The erection of b1 raft is applied
1. raft frame and layout: soft buoyant raft with 100m × 80-100m for one, platform and platform spacing 20m-50m；Centipede frame is with 100m
× 8.5m is one, platform and platform spacing 10m-15m；
2. navigation channel is wide: soft buoyant raft: 3.0m or 3.3m；Centipede frame: 1.0m-1.5m；
3. pressing from both sides seedling rope spacing: being 1.5m or 1.8m when market vegetables cultivates, the cultivation that plants vegetables, which plants vegetables, cultivates 2.0m or 4.0m；
4. float: soft buoyant raft: being fixed among two neighboring lifting rope, float spacing 1.5m；Centipede frame: single presss from both sides the flat extension of seedling rope
Exempt from attached float, when two or three folder seedling rope chain is hung in succession, folder seedling rope chain meets place, puts circular float, adjusts seedling rope buoyancy；
B2 raft frame facilities management
Folder seedling rope with seed is kept hanging set natural waters after, raft erection need to be inspected periodically and applied, discovery is damaged or floating material suspension,
Repairing in time is extractd, if it is more to find that individual seedling attaching rope juvenile sporophytes are lost, should be augmented in time, meanwhile, it sets up in time
Safety sign, warning passing ships evacuation navigation；
The detection of b3 environmental factor；
Periodic monitoring ocean temperature, salinity, pH value and intensity of illumination, make a record；Pay close attention to Typhoon Information casting and enemy
Reply outburst surroundings factor variations measure is carried out in the variation of biotic population quantity in time, and it is necessary to meet following condition for environmental factor, entirely
Year surface seawater, temperature: 7 DEG C -28 DEG C, salinity: 22 ‰ -33 ‰；PH value: 7.8-8.3；Photoperiod: 3.4:20.6-12.3:
11.7, intensity of illumination: 50 μm of ol/m2/s-250μmol/m2/s；
5) harvesting of sargassum fusifome maturation sporinite and field management；
A. collecting time and condition；
Annual 4 the end of month to mid-May, when during which ocean temperature is in 22 DEG C and following temperature, it is raw that sargassum fusifome is in best nutritional
For a long time, therefore, when nearly 22 DEG C of ocean temperatures, under the conditions of continuous 2 days or more fair weathers, sargassum fusifome should quickly be got the harvest in quickly；
B. field management
Discarded bamboo pole, plank, foam and the withered grass floated in field of vegetables is removed before harvesting in time, prevents floating refuse interference harvesting work
Make.
