Description
Technical field
The present invention relates to the artificial breeding field of undaria pinnitafida, especially a kind of pre- application and thinning-out method of undaria pinnitafida.
Background technology
Undaria pinnitafida (Undaria pinnatifida) belong to Phaeophyta（Phaeophyta）, brown sub- guiding principle（Phaeophyceae）、
Laminariales（Laminariales）, Alariaceae（Alariaceae）, undaria（Undaria）Seaweed.Undaria pinnitafida contains abundant
Nutriment, be a kind of health functional food, in the coastal extensive cultivation in the east area of the Liao River, coextensive with eastern and southern Liaoning Province in China and the Shandong Peninsula.
During undaria pinnitafida breeding production, need the seed rope section of the 2.5-3cm with undaria pinnitafida seedling, according to
The spacing of 40cm or so clips to Miao Shengshang, this process is referred to as pressing from both sides seedling.Seedling rope both ends are suspended to two table flotation in sea area after folder seedling
Between raft, the undaria pinnitafida seedling suspention of Miao Shengshang is grown in the seawater.In the process, partly adhering to unstable undaria pinnitafida seedling can be from seedling rope
On fall off, but it is remaining come undaria pinnitafida quantity often still exceed final demand quantity, so growing to 50cm or so in undaria pinnitafida
When to carry out thinning, extra undaria pinnitafida hand or other utensils are removed from Miao Shengshang, it is reasonable to ensure to retain on seedling rope
The undaria pinnitafida of quantity is fully grown, and reaches expected specification and quality.Thinning process is different according to cultivation scale, duration
Also different, it generally requires one month or more, both consumes manpower, can also delay the life for the undaria pinnitafida retained on seedling rope in various degree
It is long.It is badly in need of the easy undaria pinnitafida application and thinning-out method saved trouble in breeding production.
Invention content
The present invention is to propose a kind of method of pre- thinning, it can to solve the above-mentioned deficiency present in the prior art
The seedling being easy to fall off is removed in advance, operating process is simple, easy, and with obvious effects, can greatly reduce later stage thinning work
It measures, and ensures undaria pinnitafida yield and quality.
Technical solution of the invention is：A kind of pre- application and thinning-out method of undaria pinnitafida, it is characterised in that：The method according to
Following steps carry out：Before undaria pinnitafida folder seedling operation, temporarily foster seed rope is taken, and is 0.3cm's or more to length on seed rope
Undaria pinnitafida seedling is measured, and is A/cm by the number tag, i.e., contains A undaria pinnitafida seedling on the seed rope per 1cm,
Then seed rope is taken out from seawater, is beaten on chopping block or the side of a ship, a part of undaria pinnitafida seedling is made to be taken off from seed rope
It falls, then seed rope is placed back in seawater and is rinsed, the seed detached with seed rope is cleared up from rope,
And then it is secondary to length on seed rope be 0.3cm or more undaria pinnitafida seedling measure, by the number tag be B/
Cm ensures B：A=0.4-0.7:1,
Seed rope is operated for being divided into seedlings finally, and carries out suspended longline farming.
In the method, when being measured to the undaria pinnitafida seedling that length on seed rope is 0.3cm or more, first in seed rope
N sections of unit lengths of upper selection, and the quantity of undaria pinnitafida seedling in each section of unit length is counted, all opotisms in n sections of unit lengths
The total quantity of dish seedling is denoted as m, then have A or B=, and the value range of n is 4-8, the value range of the unit length is 2-
4cm。
The present invention compared with the existing technology, has the following advantages that：
The pre- application and thinning-out method of undaria pinnitafida disclosed by the invention, it is creative to be divided into seedlings with before suspended longline farming, first it is about to be easy to fall off
Seedling remove, whole operation process is simple, easy, and with obvious effects；By the way that thinning to be operated to preposition mode, Ke Yi great
It is big to reduce the workload of later stage thinning, while can also ensure undaria pinnitafida yield and quality.It can be said that this method has
A variety of advantages, particularly suitable for promoting and applying in the art.
Specific implementation mode
The specific implementation mode of the present invention is described below：A kind of pre- application and thinning-out method of undaria pinnitafida, follows the steps below：
Before undaria pinnitafida folder seedling operation, temporarily foster seed rope is taken, and count to the undaria pinnitafida seedling that length on seed rope is 0.3cm or more
The number tag is A/cm by amount, i.e., contains A undaria pinnitafida seedling on the seed rope per 1cm,
Then seed rope is taken out from seawater, is beaten on chopping block or the side of a ship, a part of undaria pinnitafida seedling is made to be taken off from seed rope
It falls, then seed rope is placed back in seawater and is rinsed, the seed detached with seed rope is cleared up from rope,
And then it is secondary to length on seed rope be 0.3cm or more undaria pinnitafida seedling measure, by the number tag be B/
Cm ensures B：A=0.4-0.7:1,
In above process, when being measured to the undaria pinnitafida seedling that length on seed rope is 0.3cm or more, first on seed rope
N sections of unit lengths are chosen, and count the quantity of undaria pinnitafida seedling in each section of unit length, all undaria pinnitafidas in n sections of unit lengths
The total quantity of seedling is denoted as m, then have A or B=, and the value range of n is 4-8, the value range of the unit length is 2-
4cm。
Seed rope is operated for being divided into seedlings finally, and carries out suspended longline farming.
Embodiment：
Seedling season is pressed from both sides in undaria pinnitafida, one is pulled out in sea area using canoe and hangs temporarily foster Undaria pinnitafida seedling curtain, be put into and fill seawater
In plastic barrel, plastic barrel is previously placed in shady place in cabin.
It selects 5 offspring kind ropes at random and stretches, bore hole number, which takes, is more than 0.3cm in the arbitrary five sections of unit lengths of every offspring kind rope
Undaria pinnitafida seedling quantity,（Above-mentioned unit length is 2cm）, count results are respectively 22,19,29,31,21.
Can be calculated the curtain Undaria pinnitafida seedling averag density is 12.2/cm.
Seed curtain is taken out out of square bucket, under positive and negative beat 5 respectively on the side of a ship, is put into seawater and repeatedly rinses, clearly
Reason, which is fallen off, falls and adheres to unstable seedling.
Undaria pinnitafida seedling quantity on seed curtain is counted again according to the method described above.It calculates and is more than in arbitrary five sections of unit lengths
The quantity of the undaria pinnitafida seedling of 0.3cm, count results are respectively 16,16,13,12,17.It can be calculated and beat rear skirt
Band dish seed averag density is 7.4/cm.
It calculates, it is 0.6 to beat par ratio that is rear and beating undaria pinnitafida seedling on preceding seed rope：1.
Rear seed rope will be beaten and be cut into 2.5cm long segments, cultivated according to normal folder seedling, hanging culture program.Wait for that undaria pinnitafida is grown to
When 50cm or so, the quantity of undaria pinnitafida is only slightly more more than rational quantity on seedling rope, can complete thinning work in a short time
Make, a large amount of hand labor can be saved.
