Description
Technical field
The invention belongs to agriculture field, and in particular to a kind of cultural method for improving crab resistance against diseases.
Background technology
Crab contains abundant protein and trace element, there is good tonic effect to body.Containing more in crab
Vitamin A, it is helpful to the angling of skin.Crab also has treating tuberculosis effect, and eat crab has greatly help to rehabilitation lungy.Now
During crab cultivation, most common problem is that crab is sick, and this is huge loss for raiser, improves crab and resists
Sick ability, crab survival rate is improved, it is most important for increasing economic efficiency.
The content of the invention
It is an object of the invention to provide a kind of cultural method of good in economic efficiency raising crab resistance against diseases.
In order to realize above-mentioned purpose, present invention employs following technical scheme：
A kind of cultural method for improving crab resistance against diseases, it is characterised in that it includes：Addressing, the construction of culturing pool, culturing pool
Sterilization, the cultivation of pasture and water and planktonic organism, the selection of crab seedling and sterilization, reasonable cultivation density, water quality management, water quality changes
It is good, natural enemy control, scientific and reasonable medication.
The cultural method of described raising crab resistance against diseases, it is characterised in that described addressing：Select illumination sufficient,
Water source is near, and water is sufficient, water quality is pure and fresh, and dissolved oxygen amount is high, environment quiet, does not pollute, water injection convenience, traffic convenience, pH value
Place between 7.5-8.5.
The cultural method of described raising crab resistance against diseases, it is characterised in that the construction of described culturing pool：Culturing pool
It is rectangle, is east-west, area 5-10 mus, pond depth is 1-1.5m, and bottom of pond is then covered with the thick grit soil of 5-6cm；Pond
The pool has water filling port, discharge outlet, microporous pipe ooxygenation facility, is surrounded by the anti-escape wall that bamboo chip and grenadine impale, and bottom of pond launches stone
Block, tile and bamboo cage are kept away so that crab is hidden and inhabited as veil.
The cultural method of described raising crab resistance against diseases, it is characterised in that the sterilization of described culturing pool：By pond
Water is drained, cuts out excessive mud, exposure bottom of pond 12-15d, after water high injection 30cm, with 60-80 mesh sieve thin,tough silk mistakes during water inlet
Filter, Xiang Chizhong spreads fertilizer over the fields every square metre of 100g quick lime to sterilize, and after 7-8d, reinjects water to depth of water 45-50cm.
The cultural method of described raising crab resistance against diseases, it is characterised in that the training of described pasture and water and planktonic organism
Educate：After culturing pool sterilization 3-4d, pasture and water are put in pond in a suitable place to breed, pasture and water are mainly made up of eel grass, hydrilla verticillata, water caltrop or hornwort, put
Pasture and water need the processing that carries out disinfection before supporting pasture and water, and pasture and water coverage rate is controlled less than the 0.5 of cultivating pool area；Every mu of water surface is applied
180-200kg fermentation muck is spilt, cultivates planktonic organism and rich water.
The cultural method of described raising crab resistance against diseases, it is characterised in that the selection and sterilization of described crab seedling：
Select crab shell harder, crust is complete, active, neat specification of creeping, shell color is more yellow, limbs are sound, physical strong, disease-free and injury-free
Crab seedling；Crab seedling haulage time is controlled within 5h, and 1 water is spilt every 1h in transportation；Using 3-5% food before launching
Saline sook 3-5min, soaked 2-3 times in pond repeatedly, water temperature control is consistent with the temperature of cultivating pool.
The cultural method of described raising crab resistance against diseases, it is characterised in that described reasonable cultivation density：In April
At the beginning of first arrival 5 months, the early morning or dusk of fine day are launched, and crab seedling is placed on the bank, allows it slowly to climb into water；Crab seedling is advised
Lattice are 200-240/kg, and breeding density is generally every mu of 5-7.5kg.
The cultural method of described raising crab resistance against diseases, it is characterised in that described water quality management：Water temperature control exists
15-25 DEG C, daily time opening oxygen increasing equipment 2 hours, water is changed once every 10-15d water fillings, using the side of first draining water filling again
Formula changes water, changes water 18-20cm every time；Applied per 20d and spill quick lime water transfer once, each every mu of 14-15kg, during crab shell not
Water can be changed；Daily monitoring pasture and water, pay attention to the maintenance of pasture and water, prevent pasture and water from rotting to cause water quality to degenerate, cause crab mortality,
Floating pasture and water are skimmed in time, control the area coverage of pasture and water, in case overstocked cause crab anoxic.
The cultural method of described raising crab resistance against diseases, it is characterised in that described water quality improvement：Every mu applies EM
Bacterium 0.5-0.6kg, B B-complex 0.006-0.008kg, glucose 0.12-0.15kg, amino acid 0.004-0.005kg improve
Substrate, water quality, holding water quality is pure and fresh, and water transparence is maintained at 30-40cm.
The cultural method of described raising crab resistance against diseases, it is characterised in that the control of described natural enemy：Pond is entered
The mouth of a river and delivery port are surrounded with wire netting of the bore less than 1cm, prevent other biological from entering culturing pool；It is daily to make an inspection tour cultivation
Pond, remove batrachia, class and the plague of rats entered in pond.
The cultural method of described raising crab resistance against diseases, it is characterised in that described scientific and reasonable medication：Per 15-
20d, in the morning full pool spilling head insecticidal materials and disinfecting drug of fine day；Every 7-8d, vitamin and mineral are added in bait
It is micro- necessary to the crab bodies such as matter；Crab multidimensional of being splashed before shell is closed on or duricrust are precious, the normal degenerate cllipticity of promotion.
By above-mentioned technical scheme, the beneficial effects of the invention are as follows：
The cultural method of the raising crab resistance against diseases of the present invention, it includes：Addressing, the construction of culturing pool, the sterilization of culturing pool,
The cultivation of pasture and water and planktonic organism, the selection of crab seedling and sterilization, reasonable cultivation density, water quality management, water quality improvement, natural enemy
Control, scientific and reasonable medication.The present invention provides a kind of cultural method for improving crab resistance against diseases, environment and section by pond
Cultivation so that harm of the crab away from heavily contaminated, prevention crab disease occur, and improve survival rate and yield, clean safe,
Natural nuisance-free, meet growth rhythm, quality more preferably, meat is solid, so as to obtain good economic benefit.
