Abstract
The invention discloses a method for applying scanning-type automatic flushing to indoor porphyra yezoensis conchospore seedling collecting. Before conchospore seedling collecting and during the conchospore seedling collecting, the diffusion situation of conchospores is checked; flowing water stimulation is performed on a large-area continuous seedling pool by adopting scanning-type flushing, wherein the scanning-type flushing is realized by spraying water at a plurality of points; the flushing strength is low; each branch water pipe sprays water uniformly; the water is sprayed linearly in the left-right direction and is pushed forwards gradually; the water flushing points are arranged in rows and lines in the transverse and vertical directions. The flushing conchospore collecting range and the water spraying strength are improved by integrally connecting main water pipelines and improving the water inlet strength. By flushing, the growth of filamentous alga filaments is promoted and the development of alga filaments is expanded; the mature and the diffusion of the conchospores are promoted; sinking conchospores are flushed to be in full contact with a net curtain and are attached to the net curtain; the diffusion rate and the attachment rate of the conchospores are improved; the waste of the conchospores is reduced; the conchospores are collected uniformly by the net curtain, and the net curtain is put out to sea timely; the labor cost is reduced; the seedling cost of porphyra yezoensis is reduced.
Description
Technical field
The present invention relates to a kind of laver culture technology, particularly a kind of scan-type auto-flushing is used for the method that indoor porphyra yezoensis conchospore is collected seedling.
Background technology
Porphyra natural marine food, its delicious flavour, nutritious, and have health care, sell well in international market, along with the raising of modern life level always, particularly our people's enhancing that health care of food is realized, people more and more pay attention to the health care of marine alga, and its space, domestic market is very large, and the market competitiveness is stronger.
Along with the development of human civilization, growth in the living standard, the diseases such as " rich man's disease " hypertensive cardio-cerebrovascular more and more harm humans are healthy.The natural function of the step-down that laver has, enhancing blood vessel elasticity, causes the extensive concern of people.Want food to sea, want the consciousness of medicine constantly to strengthen to sea, the social demand of laver derived product is huge, and along with its demand of raising of domestic level is by increasing.
Porphyra yezoensis is a kind of marine alga that artificial cultivation economic worth is the highest in the world at present.Nearly 3,000,000,000 dollars of its tame annual value of production, accounts for 2/3 of whole world artificial cultivation marine alga.Then mainly concentrate on 3 coastal cities of our province at its artificial cultivation of China, its output accounts for more than 90% of the whole nation.
The existing cultured area in Lianyungang about 180,000 mu, practitioner is people more than 6000, seasonal casual labourer 500,000 person-times, existing automatic laver time processing unit more than 140 cover, secondary operations unit 20 multiple stage cover.Time processing laver 2,000,000,000, nearly 200,000,000 of secondary operations laver, wherein 90% with upper outlet, the wound output value more than 900,000,000 yuan, whole city's laver seedlings growing area more than 120,000 square metre.Laver had become one of pillar industry of Lianyungang mariculture already.
Full Lianyungang laver culture has semi-floating, plug in pole formula, reversible type, the floating breeding way such as streaming, denidation formula, is the most multifarious area of China's laver culture mode, no matter how breeding way changes, and the disparities between supply and demand of porphyra yezoensis seed are more and more outstanding.
Present stage, in Jiangsu Province, porphyra yezoensis conchospore is collected seedling adopts the mode of artificial bath more, and often, the existence of problem have impact on the seed output and quality of spot laver thallus to existing problems to a certain extent.
First, the indoor seed rearing of porphyra yezoensis, especially indoor conchospore labour cost of collecting seedling is very high, as porphyra yezoensis conchospore is collected seedling period, within 15 days, calculate according to collecting seedling, everyone is responsible for the artificial bath management of 40 square metres, if cultivate 1000 square metres of shell conchocelises, bath is needed every day to collect seedling personnel 25 people, according to everyone 100 yuan/day, nearly 40,000 yuan of expense of manually washing by water is needed during collecting seedling, namely every square metre of shell conchocelis is cultivated and is added 40 yuan of costs, according to the 120000 square metres of calculating of the existing cultured area in Lianyungang, need nearly 5,000,000 yuan of artificial bath expense, in fact, in Lianyungang Area, for many years, conchospore collects seedling the time generally at 20 days, nearly 40 days, it is manually washed by water and collects seedling expense at about ten million yuan.For the field man being engaged in porphyra yezoensis nursery, this is many expense.
Second, look for work difficult, personal management is difficult, and artificial bath gathers the conchospore of porphyra yezoensis, and its workman's workload is very large, generally from morning 6:00 to 1:30 at noon, have water pump in arms in bath, even if the excellent labour in rural area starts also can feel pain in low back and legs, this work young man can not do always, the labour in rural area mostly goes out and has worked, so look for work difficulty; Woman worker above middle age when the personnel called in are many, not bad management of starting working, time long tube reason just difficulty, be difficult to allow workman wash by water completely as requested, somebody leaves or constantly asks for leave in midway, and artificial bath gathers the conchospore of porphyra yezoensis, personal management difficulty.
3rd, manually wash by water, the conchospore attachment of lace curtaining is uneven, causes a large amount of conchospore wastes, incurs loss through delay conchospore seeding collecting season, cause loss to porphyra yezoensis cultivation.Artificial bath, can not be evenly, it is a lot of that some places rush, some places are not almost flushed to, this just causes the loss of two aspects, the place not being flushed in time or being seldom flushed on the one hand, the conchospore that diffuses having slatterned in vain on major part shell, on the other hand, each local spatfall quantity certain density must will be reached because lace curtaining goes out pond, according to such requirement, even if seedling total amount is a lot of on lace curtaining, lace curtaining also cannot go out pond, like this, just cause a large amount of conchospore wastes, incur loss through delay conchospore seeding collecting season, loss is caused to porphyra yezoensis cultivation.
4th, broken shell is many, and conchospore waste is many.Workman gathers during conchospore in bath, and in order to increase effect of collecting seedling, workman substantially walks about in laver nursery pond, and a large amount of often filamentous shell of its result is tramped, some powderings; When adopting seedling and rinsed at every turn, some have the filamentous shell fragment of seedling to be gone out outside pond by with water, in addition, when arranging shell, the little filamentous shell fragment of major part has the one side of seedling, is attached at the bottom of pond, even if the shell be attached at the bottom of pond diffuses in a large number, but it is little with the conchospore that contact of cultivation lace curtaining to enter water body in time, like this with regard to virtually causing a large amount of wastes of conchospore, delays plunging into the commercial sea the time of lace curtaining to a certain extent.
In sum, artificial bath is at present collected seedling, add seedling cost, waste a large amount of porphyra yezoensis conchospores, delay plunging into the commercial sea the time of lace curtaining, causing loss in various degree to spot laver thallus mariculture, how to solve artificial bath and gathering conchospore problem, is the problem needing present stage to solve.

By taking a sample to check, find that the conchospore quantity that lace curtaining is sprouted just can arrange out pond after reaching requirement, supports temporarily, plunge into the commercial sea.
The pond new lace curtaining of continuation lay appearing lace curtaining carries out conchospore and collects seedling.
Collect seedling afternoon every day period, no matter whether lace curtaining goes out pond, all by shell conchocelis towards upper, will be emitted on uniformly in nursery pond, reduces shell accumulation, fragmentation as far as possible.
On the same day, conchospore according to the cloudiness of the mud scum situation on shell, nursery pool inner water, the situation of adapted water, suitably changes water, generally entirely to change, diffuse peak period do not change water at conchospore after collecting seedling and terminating.
After the cultivation lace curtaining adopting conchospore is plunged into the commercial sea, the sprouting of conchospore and thallus growth and ocean temperature change associate close, when ocean temperature is at 19 ± 1 DEG C, the germination physiology of conchospore is desirable, after, the optimum growth temperature of spot laver thallus also increases along with thallus length or width and reduces gradually, and this is the result that porphyra yezoensis and natural environment adapt to for a long time; If when the lace curtaining adopting conchospore is plunged into the commercial sea, water temperature is higher, conchospore can not sprout production in time, and lace curtaining is for a long time under the impact of wave, and conchospore has a large amount of leakage; Meanwhile, when ocean temperature is higher, just the mating season of the assorted algae such as Enteromorpha, a large amount of Enteromorphas etc. are attached on lace curtaining, if like this, the lace curtaining enclosing a large amount of Enteromorpha just cannot carry out laver culture again, and its loss is conceivable; If water temperature is on the low side when lace curtaining is plunged into the commercial sea, the sprouting of conchospore misses optimum temperature, and conchospore germination is slow, later growth is slower, a so-called step is unable to catch up with, and is unable to catch up with step by step, and the seed output and quality (early stage dish quality is good) of laver culture will receive impact in various degree; Lace curtaining is plunged into the commercial sea slower, and its culture efficiency is poorer, and the lace curtaining even adopting conchospore may be abortive haul.The time period that lace curtaining is plunged into the commercial sea so collect seedling is very important, and according to the experience of the author, in Jiangsu Province, the lace curtaining Best Times of plunging into the commercial sea should in annual September 26 to October 5, and this time slightly adjusts along with the water temperature change of different year.
Bath, can promote growth and the growth of filamentous; The maturation of conchospore can be promoted and diffuse; The punching of the conchospore of heavy property can be got up fully to contact with lace curtaining and is attached on lace curtaining, etc.The success or failure that the maturation that the dynamics of bath, the uniformity and mode directly affect overall shell and the uniformity and lace curtaining of diffusing, affecting lace curtaining upper casing Spore adhesion go out the pond time, affect the degree of the accumulation of filamentous or fragmentation, affect the overall utilization rate of conchospore, affect time that lace curtaining plunges into the commercial sea and mariculture thallus of porphyra.
On the stalk of pond or under seedling rearing room brace summer, turn double track runway by angle bar peace; Be welded into cuboid frame with the stainless steel tube of 20mm, in base four welded corner joint four small wheels, the double track runway can made at angle bar run; Cuboid frame add base and with fixed motor (400W--600KW); A welding groove in the middle of framework upper surface, for supporting bath supervisor; At the two ends of double track runway, remote sensing switch is installed, to control turning to of whole framework.
With the pvc pipe (concrete length is determined according to seedling rearing room, nursery pond and need of production) of a diameter 50mm, on pvc pipe, 10cm of being often separated by, bores the circular hole of a 10mm; Connect the thin pvc pipe of length 10cm, do bath distributive pipe in a row, note punching to pvc pipe, doing distributive pipe directly over the water surface; According to the size of water pump, to pvc pipe punching above the stalk of pond, do the pvc pipe head of water pump water supply hose.
PVC water pipe is fixed in the groove above motor rack, if worry that pvc pipe is soft or give a discount, with reinforcing bar fixing PVC pipe; In conjunction with actual conditions, every 8m-12m, on the stalk of pond or under seedling rearing room brace summer, install a motor, like this, the bath distributive pipe once row can carry out the bath of scan-type to nursery pond shell conchocelis.
Also main pvc pipe can be made many rows, and connected into as a whole by pvc pipe, and reasonable disposition, mounted motor, by in the water pipe groove being fixed on above motor rack steadily, the entirety that pvc pipe connects into, washed by water by distributive pipe, promote that the conchospore of porphyra yezoensis is ripe, diffuse, attachment etc.
By wattage, the number of water inlet water pump, flow velocity and the bath strength of distributive pipe can be regulated; By blocking distributive pipe, carry out the bath of part seedling pond; Can be adjusted by motor, adjustment gathers the bath frequency of conchospore; By the height of runway, bath strength can be increased, etc.
