The culture method for the kelp, disclosed by the invention, comprises the following steps: 1, selecting a sea area; 2, installing culture valves; 3, purchasing kelp seedlings; 4, temporarily culturing the kelp; 5, separating the kelp seedlings; 6, managing cultured kelp; 7, harvesting the kelp. According to the culture method for the kelp, disclosed by the invention, the selection of the culture sea area is scientific and reasonable, and the culture process is simple and easy; moreover, the fertilizing amount and the kelp water layer depth are adjusted according to the growth characteristic of the kelp, so that the growth effect of the kelp is better, and the obtained product quality is higher.
Description
Technical field
The present invention relates to field of marine product cultivation technology, specifically the cultural method of a main laminaria.
Background technology
sea-tangle, be a kind of at low temperature
seawaterthe raw brown alga plant in large-scale sea of middle growth, belongs to
marine algaclass plant, its edible way is various.Because it has the iodine of high-load, to prevention goitre, there is positive role, and sea-tangle is delicious and cheap, is widely loved by the people.Sea-tangle has many decades in the cultivation history of China, and particularly since the 80s and 90s in last century, laminaria culture industry obtains fast development, and sea-tangle output significantly promotes, and sea-tangle has become the homely vegetable of people.The artificial cultivation of China sea-tangle, North gets Liaoning, reaches Fujian, Coast of Guangdong Province in the south, and output accounts for 80% of world's sea-tangle output.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of scientific and reasonable, sea-tangle can be made to keep the laminaria culture method of good growth.
The present invention takes following technical scheme:
The cultural method of one main laminaria, comprises the following steps:
(1) selection in sea area
Sea area answers principle in the offshore sea waters without industrial or agricultural and Sewage Pollution, seawater surface is without greasy dirt, without floating solid, the depth of water 10 ~ 20m, the average annual flow velocity of seawater at 0.5 ~ 0.8m/s, average annual wind speed lower than 1m/s, more than seawater transparency 2m, the average annual water temperature of seawater surface 13 ~ 17 DEG C, sea area substrate is the husky end or silt bottom;
(2) setting of valve is cultivated
Cultivation valve is arranged along water (flow) direction, often reserves the shipping agency passage of 5-6m in the middle of row's cultivation valve; Stake selects length to be 2 ~ 2.5m, the firm corrosion resistant timber of diameter 15 ~ 20cm, and arranges 2 ~ 3 hangnails at timber low side; Stake rope and seedling rope all adopt vinyon rope, and the length of stake rope is sea water advanced 1.2 times in described sea area, the length 2 ~ 2.5m of seedling rope; The middle part of seedling rope hangs one block of stone, regulates the underwater penetration of sea-tangle during in order to cultivate, and respectively to hang a buoyancy at seedling rope two ends be the cursory of 15kg;
(3) Kelp seeding is purchased
Be selected in and buy Kelp seeding September, Kelp seeding selects growing way good, and color is puce, and without pathology, long 1 ~ 3 centimetre of seedling, keeps Kelp seeding moistening every 20 minutes sprays seawater in Kelp seeding transportation;
(4) Kelp seeding is supported temporarily
After kelp seedling enters from nursery, 2-3 bar rope is tied up the same side at the seedling growing container with intensive seedling, seedling growing container is put into the Port of Fangcheng Beibu Bay of water temperature below 20 DEG C to support temporarily, require that seedling is apart from sea 1.5-2.5cm, rope opposite side is fixed on steck.Observe seedling recovery situation and seawater transparency, constantly the seedling distance sea degree of depth is adjusted, support temporarily and kelp seedling is adjusted to apart from sea 0.5m dark in a 7-15 days.
(5) sea tangle seedling distributing
The intensive seedling be attached on seedling growing container after supporting temporarily is cleaned with a pointed instrument, and dispersion clips to the Miao Shengshang formed, and a point seedling specification is advisable with 9-12 centimetre.In order to improve sea-tangle output, economize on resources, and be unlikely to the overstocked so that sea-tangle undergrowth of laminaria culture, Kelp seeding divides and presss from both sides lattice according to actual conditions every lattice during seedling and adopt the mode of single folder to carry out a point seedling.Note not damaging seedling when dividing seedling, reduce the young plant dew empty time, avoid Exposure to Sunlight, sea-tangle rhizoid will be clipped in seedling rope centre, prevents seedling from coming off and crushes growth site.
(6) sea-tangle form management
Regulate water layer, illumination power directly affects growth and the disease generation of sea-tangle, should by just divide the sea-tangle of seedling once U-shaped be deeply hung in seawater make sea-tangle distance underwater 4-5m, recovery along with seedling in 15-20 days and growth, by stretching gradually for the seedling rope cultivated kelp, cultivation water layer is progressively up carried, until sea-tangle distance sea 5m is dark, and seedling rope once straight line substantially, the different growth period of sea-tangle is different to the demand of illumination, constantly should adjust Kelp seeding rope according to sea-tangle growing state, uneven stage sea-tangle requires lower than mushroom stage to illumination, cultivation water layer should be deep to 5-6m, the illumination of adult stage sea-tangle requires the strongest, and cultivation water layer should more shallow 3-4m.
(7) sea-tangle results
When seawater is greater than 30 DEG C, sea-tangle stops growing and starts to become sick, and sea-tangle is by a large amount of underproduction, and Beibu Bay, guangxi regional temperature is more northern or even Fujian is all high, therefore just should gather in the crops in time when North Sea water temperature is at 25-30 DEG C.
The invention has the beneficial effects as follows: the cultural method of a main laminaria of the present invention, scientific and reasonable to the selection of mariculture area, breeding process is simple, and adjusts fertilizing amount and sea-tangle water depth according to the growth characteristic of sea-tangle, the growth result of sea-tangle is better, and the product quality of acquisition is higher.
Embodiment
With an embodiment, the present invention will be further described below
The cultural method of one main laminaria, comprises the following steps:
(1) selection in sea area
Sea area answers principle in the offshore sea waters without industrial or agricultural and Sewage Pollution, seawater surface is without greasy dirt, without floating solid, the depth of water 10 ~ 20m, the average annual flow velocity of seawater at 0.5 ~ 0.8m/s, average annual wind speed lower than 1m/s, more than seawater transparency 2m, the average annual water temperature of seawater surface 13 ~ 17 DEG C, sea area substrate is the husky end or silt bottom;
