Plant vegetables and drop into Miao Chihou, need accomplish the seedling pond management of following several respects, 1. will guaranteeing plants vegetables fully unfolds; 2. will ensure that No. 3 ~ 4 hydraulic giants rinse and turn over dish every day, ensureing to plant vegetables accepts uniform illumination and nutrition; 3. to ensure that seawater contains sufficient dissolved oxygen; 4. to ensure 100 ~ 200 μm of ol/m 2the intensity of illumination illumination of/s 10 ~ 11 hours, 5. has the place of indoor culture condition, should ensure the periodicity of illumination of 12:12 ~ 15:9 as far as possible.
Manually cultivated through 5 ~ 8 days, plant vegetables and will carry out sexual propagation, planting vegetables of artificial precuring, generally start the discharge of smart ovum morning 4 ~ 5, ovum, smart ovum are progressively fertilized formation rataria afterwards, about when this process will last till the same day 17.Fully-developed fertilized egg (zygote) starting gradually departs from female receptacle, fertilized egg is deposited to bottom seedling pond, and As time goes on, in unit interval, the fertilized egg quantity departing from female receptacle increases gradually, during period midnight 0 ~ next day 2 time, quantity is maximum, to next day 6 time, substantially complete this process.
Utilize the mode discharged water to collect rataria, first remove impurity with 80 order yarn tulle bags, then collect rataria with 300 order yarn tulle bags; Embryo after collection, rapid placement is filled it up with in the Plastic Drum of filtering sea in advance, and leads to oxygen in time.
3) being laid on uniformly bottom seedling pond by the spatfall curtain in advance through disinfecting, making spatfall curtain keep smooth, arranging mutual overlapping portion, after putting in order, inject the high seawater of about 30cm in Xiang Miaochi, sea conditions is identical with the precuring condition that plants vegetables.According to seedling pool area, (the spatfall curtain usually, for breed breeding should remain on about 500,000 rataria/m to rataria number needed for counting statistics 2), then artificial spreading embryo is carried out, the mode of artificial spreading embryo is not quite similar, the watering can that some uses are watered flowers sprays, can ensure that the distribution of rataria on spatfall curtain is comparatively even, in addition, there are the personnel of experience in breeding for many years, water ladle directly can be used to carry out spreading, also can ensure the even of rataria.
After completing rataria spreading, through the time of 2 ~ 3 days, rataria completes set growth substantially.In order to ensure growing fast of embryo, by manual cleaning in pond and the methods such as fresh seawater can be replaced, for embryonic development creates good growing environment.Then the mode by running water displacement every day continues cultivation 3 ~ 4 days, can put in a suitable place to breed in natural waters.
4) spatfall curtain is positioned over natural waters cultivation 120 ~ 150 days, grow into the juvenile sporophyte with three base leaves, stem and lanceolars or centric leaf, September ~ October takes off juvenile sporophyte from spatfall curtain, manually presss from both sides seedling, then juvenile sporophyte is placed in natural waters puts in a suitable place to breed.
If spatfall curtain also remains many less juvenile sporophytes, spatfall curtain can be placed back in holding culture offshore, through about 15 ~ 20 days, again fetch spatfall curtain, win juvenile sporophyte, so repeatedly, a slice spatfall curtain can repeat to win 3 ~ 4 times.
Because China southeastern coastal areas Sheng in summer scrapes SE Monsoon, also be the Main way of Landed Typhoon, so, put the sea area of rataria in a suitable place to breed, select stormy waves less as far as possible, current are less, water quality is limpid, pollution-free and fresh water discharge, effectively can hide east, the bay in the southeast and southern Landed Typhoon direction and Ao mouth and be advisable.Range of the device can choose bamboo raft based on factors such as sea condition, the seawater transparency or stainless steel tube structure of wu gong method of hanging breeding, generally bamboo raft can be applied to the winds and waves are slightly, slightly cloudy sea area, water quality and stainless steel pipe is suitable for the wind and waves, water quality is slightly smaller area.
Spatfall curtain is put after natural waters puts 3 days in a suitable place to breed, field management can be carried out, major way checks on spatfall curtain, whether silt and harmful animal algae can have influence on growth of the embryo growth, if quantity of sand and mud is comparatively large, harmful animal algae is more, then need to clean, if quantity of sand and mud less harmful animal algae is less, can proper extension scavenging period.The embryo development stage is important production phase of sargassum fusifome artificial breeding seed, just one of the field management work during wherein this of cleaning spatfall curtain, management work important during prevention and cleaning harmful animal algae and animal are also this.8 ~ September, Dongtou seawater water temperature is increased to about 28 DEG C gradually, now, the harmful animal animals such as harmful animal algae and clam worm, sea anemone, oyster, barnacle such as Polysiphonia japonica, sliver sea lettuce, Enteromorpha also can be increased gradually, sudden " outburst " of these harmful organisms, all can cause a large amount of losses of seed, time serious, directly can cause total crop failure.If when running into sudden harmful organisms " outburst ", conventional harmful animal sweep-out method, mainly comprise, use 10% ammonium sulfate sea water immersion 8min, effectively can kill green bristle algae, use the citric acid solution of 8% to soak 5min and can effectively remove the algae such as Polysiphonia japonica, sea lettuce, Enteromorpha, use freshwater soaking 15 ~ 20min can effectively remove the methods such as animal class, eliminate or reduce seed loss.
During folder seedling, be clipped in by the rhizoid of juvenile sporophyte on 400 strands of polyethylene fibre ropes of 3.3 ~ 3.5 meters long, seedling rope selects quality soft as far as possible, and the material that feel is soft, such material can effectively prevent from falling seedling because of the frictionally damage between seedling and seedling rope.Seedling spacing is 22 ~ 25cm under normal circumstances.
Juvenile sporophyte puts the initial stage in a suitable place to breed, because water temperature is higher, harmful organisms still can produce adverse influence to sargassum fusifome juvenile sporophyte, seedling rope after employing 10 ~ 12 of trying one's best during this clips is one group, put in a suitable place to breed in a short time, such process, the population effect of sargassum fusifome juvenile sporophyte can be played, by the swing of sargassum fusifome juvenile sporophyte in natural flows, reduce set and the invasion and attack of harmful organisms, when ocean temperature is down to 24 DEG C, again they are separately kept hanging, now, the rhizoid of sargassum fusifome consolidates labor substantially on seedling rope, for its subsequent growth has established favourable condition.
When dividing rope, choose the soft raft culture mode of quality softness, rope spacing minimum range need remain on about 1.5 meters as far as possible.Point rope time carried out according to the morning and evening of juvenile sporophyte growth and development time, and under normal circumstances, first arrival next year 1 in point rope time of Dongtou sargassum fusifome in annual November is monthly carries out.
After point rope, just enter sporophyte sea area management phase, period regularly will patrol in field of vegetables whether have the article such as pollutant or rubbish, if exist, periodic cleaning, antipollution increase or expansion.Carry out these work, favourable growing environment is created in the growth that can be sargassum fusifome, enables the growth that sargassum fusifome is healthy.
