(2) nursery pond and a surrounding enviroment of growing seedlings dries
Nursery pond has been cultivated after a collection of shrimp seedling, and nursery pond must could be thrown in the young through 7-10 days rest and reorganization, and the pond is fully dried, and preferably the sun directly dries;
(3) nursery pond and an environment disinfected of growing seedlings
Use strong chlorine oil 1000-1300g/m
3, formaldehyde 1000-1300ml/m
3To the sterilization of splashing of each nursery pond and a whole surrounding enviroment of growing seedlings, splash after the sterilization with strong chlorine oil earlier, with the formaldehyde sterilization of splashing, sealed door and window then 48 hours again, allow pond and surrounding enviroment enclosing sterilizing between whole growing seedlings; Behind enclosing sterilizing, nursery pond is intake between growing seedlings, water for larval nursing every index regulation and control routinely;
(4) throw in the young
1. throw in young arrangement of time between growing seedlings: all pile between must growing seedlings one with one to two day time when throwing in the young;
2. young lower storage reservoir method: after the young is bought back, be placed on the nursery pond next door, prepare the basin of two diameter 50-60cm in advance, a basin is contained the water of going up this nursery pond, with a diameter 30-40cm, mesh is that 100 purpose bolting silk mesh bags are placed in the basin, the packed young is slowly poured in the bolting silk net, every in the bolting silk net, another basin is contained the water of going up this nursery pond the young again, the water surface is put into formaldehyde 200-250ml/m from pelvic surface of sacrum 5cm
3As disinfectant, then the young in the bolting silk net is moved on in the basin of being furnished with disinfectant, the shaker screen tulle promptly shifts out through 3-5 second gently, is put in the nursery pond, and each operation is drawn analogous conclusions, up to whole young are put into nursery pond through sterilization.
(5) seedling management: seedling-cultivating method management routinely.
The present invention is by the complex art method that physics, environment, medicine and management etc. combine, can avoid effectively because of environmental pollution to the causing a disease of the young, prevent to take place because of environmental pollution causes disease, improve survival rate.Average survival between the enforcement present technique is grown seedlings can reach 35-60%, can improve 30-70% than current techique, and growth is fast, and seed size is neat, and the seed quality is good.
Advantage of the present invention is:
1. nursery pond earlier through fully drying or drying, reduces the pond pathogen contamination, for pond afterwards and the pasteurised completely between growing seedlings lay the first stone.
2. with potent medicine enclosing sterilizing is carried out in pond and space, surrounding enviroment between growing seedlings, can effectively control disease infection and generation.
3. one grow seedlings a 1-2 days (best one day, maximum 2 days) throws in the full young, can effectively prevent from early stage to throw in the young and the pollution between growing seedlings be brought the influence of being thrown in the early growth and development of the young the later stage.
4. in 1-2 days, throw in the full young between growing seedlings for one, can avoid one to divide between growing seedlings and threw in the time interval gap that the full young brings in several days to more than ten days, can improve the turnover period between growing seedlings more than 30% and the availability in pond.
Embodiment
Present prawn seedling breeding generally divides prawn young breeding field and seedling culture field.Young breeding field is the close shrimp of special cultivation, lays eggs, hatches the young.The seedling culture field is to buy the young from young breeding field to cultivate to the commercial specification seedling and sell.The present invention is meant from buying the young and throws in method into the high-efficient safety seedling cultivation of this valency section of pond.
The concrete steps of this method are as follows:
(1) cleaning of the nursery pond and a surrounding enviroment of growing seedlings
Nursery pond is thoroughly cleaned up, and the surrounding environment of nursery pond also must clean up, foreign material around eliminating, and clean and tidy, clean between keeping growing seedlings is in case the cross-infection between the Chi Yuchi.
(2) nursery pond and a surrounding enviroment of growing seedlings dries
Nursery pond has been cultivated after a collection of seedling, and nursery pond must could be thrown in the young through 7-10 days rest and reorganization, and the pond is fully dried, and preferably the sun directly dries.
(3) nursery pond and an environment disinfected of growing seedlings
Use strong chlorine oil 1000g/m
3, formaldehyde 1200ml/m
3To the sterilization of splashing of each nursery pond and a whole surrounding enviroment of growing seedlings.After earlier sprinkling the wine sterilization, with the formaldehyde sterilization of splashing, sealed door and window then 48 hours again, allow pond and surrounding enviroment enclosing sterilizing between whole growing seedlings with strong chlorine oil.Can effectively kill various bacteriums and infectious disease, after throwing in the young, prevent laying the first stone of disease.(if original pond was seriously polluted, and repeated disinfection is once more in case of necessity).
Between growing seedlings behind enclosing sterilizing, the nursery pond of just can intaking (water for larval nursing is handled other method, every index regulation and control of water quality, operation sequence etc. by normal current techique).
(4) throw in the young
1. throw in young arrangement of time between growing seedlings:
Throw in the young and all pile between preferably one being grown seedlings in one day, a pond of growing seedlings that has is many, also will all pile the pond at second day, not so, can influence survival rate of seedling and quality that the later stage throws in the young.Its reason is: between growing seedlings through 48 hours enclosing sterilizing, the clean environment of growing seedlings of this moment, pollution-free.The young is individual little early stage, a little less than resistance against diseases, the anti-infection ability, if all pile between once one being grown seedlings this moment, has just reduced the chance of mutual infection, and each the nursery pond young between whole growing seedlings can both be grown by healthy normal growth.If divide input in many days on the contrary, will cause the previous input young because of the various factors of management has influence on clean environment between whole growing seedlings, cause the later stage to throw in the young infection of pest takes place easily.A directly shadow cross-infection of growing seedlings.
2. young lower storage reservoir method:
After the young is bought back, be placed on the nursery pond next door.Two plastic basin of pre-preparation (diameter 50-60cm), a basin is contained the water (from about pelvic surface of sacrum 5cm) of going up this nursery pond, the bolting silk mesh bag (the bolting silk mesh is 100 order sizes) of a diameter 30-40cm is placed in the basin, again the packed young is slowly poured in the bolting silk net, make the young every in the bolting silk net, (from pelvic surface of sacrum 5cm) put into formaldehyde 200ml/m after another basin was contained the water of going up this nursery pond
3Disinfectant as the sterilization young moves on to the young in the bolting silk net in the basin of being furnished with disinfectant then, and the shaker screen tulle promptly shifts out through 3-5 second gently, is put in the nursery pond, and each operation is drawn analogous conclusions, up to whole young are put into nursery pond through sterilization.
(5) seedling management: by normal seedling-cultivating method management.
