Description
Technical field
The invention belongs to the technical field of laminaria culture, particularly relates to a kind of long seedling rope laminaria culture float raft and its cultivation side
Method.
Background technology
Kelp, is a kind of raw brown alga plant in large-scale sea grown in low temperature seawater, belongs to seaweed plant, its edible way
It is various.Because of its iodine with high-content, there is positive effect to prevention goitre, and kelp is delicious and cheap, it is deep by people's
Like.
Cultivation history of the kelp in China has many decades, and particularly laminaria culture industry obtains since the 80s and 90s in last century
To fast development, kelp yield is substantially improved, and kelp has become the homely vegetable of people.The artificial cultivation of China kelp is North gets the Liao Dynasty
Rather, to Fujian, Coast of Guangdong Province, yield accounts for the 80% of world's kelp yield in south.
In recent years, the artificial raft culture of kelp, substantially increases the yield of kelp, meets people's life and industry
The needs of production.The presently disclosed laminaria culture float raft used mainly fixes floating well rope by fixed short wooden stake through short wooden stake well rope, floats on well rope
Equipped with large-scale float, floating well rope is floated on sea, hung between floating well rope through lifting rope and link integral seedling rope among a row two.
In this traditional floating raft type cultural technique, due to gravity factor, it is not in per the kelp on offspring rope same
The depth of water, causes the kelp individual difference on same seedling rope very big, influences yield.Moreover, in terms of the length of seedling rope, one band of Shandong
The seedling rope for being substantially 2 meters of two root long connects, and the seedling rope length degree in Liaoning is longer, most long to reach 8 meters；Since kelp is supported
Grow and belong to labor-intensive industry, after the 1990s, wage for workmen increases substantially, the work in current laminaria culture
Money expenditure has accounted for more than half of production cost；The seedling rope laminaria culture technology of this length cannot use do mechanization operation, drop
Low labor productivity, seriously affects economic benefit.
The content of the invention

Round log.For example, short wooden stake 1 can be black pine short wooden stake；Certainly, short wooden stake 1 can also be other hard round logs.
Attached drawing 1 is only the schematic diagram of the present invention, for brevity, merely illustrates 2 row's buoyancy well ropes 3,5 row's seedling ropes 10, a small amount of
Plastic float 4 and the small float 11 of a small amount of foam；In the present invention, the foam between adjacent two buoyancy well rope lifting ropes 6 is small floating
The number of son 11 is 7, positions the plastic float 4 on the plastic float 4 and buoyancy well rope 3 on well rope 7 and is on same horizontal plane
On sea.
A kind of long seedling rope laminaria culture method of the present invention, progress kelp is supported on above-mentioned long seedling rope laminaria culture float raft
Grow, concretely comprise the following steps：1）, folder seedling：When Kelp seeding length reaches 150-300mm, foam small float 11 is equipped with what is got ready
Seedling rope 10 carries out folder seedling, Kelp seeding spacing 70-80mm；2）, hang seedling：First 10 both ends of seedling rope are determined by positioning well rope lifting rope 9 and tying up to
On the well rope 7 of position, then, the buoyancy well rope lifting rope 6 got ready on buoyancy well rope 3 is sequentially tied on seedling rope 10, finally, in seedling rope 10
The position of buoyancy well rope lifting rope 6 is the dropstone of a weight 500-600g；3）, lifting water layer：By shorten the first lifting rope 5 and/or
The length lifting water layer of buoyancy well rope lifting rope 6；4）, increase buoyancy：Buoyancy is increased according to kelp growing way situation, buoyancy control is with floating
1/2 to 3/4 embedment of the plastic float 4 on power well rope 3 is advisable under water, and increase buoyancy can also be as the means of lifting water layer；5）、
Harvest：During harvest, first the buoyancy well rope lifting rope 6 on buoyancy well rope 3 is untied, then, unties the positioning well rope lifting rope 9 on positioning well rope 7, i.e.,
It can be harvested using harvest machinery.Under normal circumstances, transversely main current direction is set seedling rope 10, the plastics on buoyancy well rope 3
The number of float 4 is 10-30.
By laminaria culture method and the traditional laminaria culture method of the present invention according to identical in identical briny environment
Condition the kelp of same seed is cultivated, now Dalian, Lvshun, five islands of Long Island Bei, Rongcheng Sang Gou gulfs to the north of
A kind of sea area big etc. depth of water stream and the result in the two class sea areas on the shallow waters such as Peng Lai, Yantai, Mouping thin beach progress laminaria culture
Statistics is as shown in table 1, and in table 1, for kelp yield using limnetic dry kelp as standard, rate of growth is laminaria culture method of the invention with passing
It is that system laminaria culture method is compared as a result, production efficiency for the present invention the production of laminaria culture method more traditional laminaria culture method
The increase rate of efficiency.
The Comparative result of the laminaria culture method of the present invention of table 1 and traditional laminaria culture method
As can be seen from Table 1, the length of seedling rope 10 is 100-200m in long seedling rope laminaria culture technology of the invention, traditional kelp
The length of seedling rope 10 only has 8m in cultural technique；In the kelp of a kind of sea area cultivation, its yield reaches 2500-3000Kg/ to the present invention
Mu, in two class sea areas, its yield of the kelp of cultivation reaches 910-1510Kg/ mus, kelp yield is added 20-30%；By kelp
The labor workload of needs in breeding process is reduced to 7-15 work days/mu, moreover, these are only manually to carry out tether, solution
The light manual labors such as rope, without pulling the so heavy physical labor of kelp as in traditional laminaria culture technology
It is dynamic；The present invention realizes the do mechanization operation in links such as folder seedling, harvest, dryings, puies forward the production efficiency in kelp harvest stage
High 120-130%.
Therefore, the beneficial effects of the invention are as follows：The present invention can be such that the length of seedling rope 10 significantly lengthens, easy to mechanization
Operation, harvest stage work efficiency have obtained more than ten times of raising, reduce the artificial labor in links such as folder seedling, harvest, dryings
Power；The present invention only need to manually carry out the light physical labors such as tether, solution rope, without the physical labor of the weight as pulling kelp
It is dynamic, artificial usage amount is reduced more than ten times, operating speed is accelerated.The present invention is directly connected to the small float 11 of foam on seedling rope 10,
Solve the problems, such as since seedling rope 10 is sagging caused by gravity factor, every plant of kelp is had well by optical condition, kelp production
Amount improves more than 20%.Further, since kelp growing way is basically identical, the method without being received between taking, disposable harvest can also drop
The low harvest amount of labour used.Moreover, the small float 11 of the foam being arranged on seedling rope 10, light-weight, volume less can be with seedling rope 10 together
Store, do not influence to press from both sides the operation such as seedling, harvest, even if needing to load and unload because it can be also extremely convenient in land completion.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on, should all be included in the protection scope of the present invention god.
