Abstract
The present invention discloses an incubation method of Chinese soft-shelled turtle. The operation process of said incubation method includes the following steps: (A), orderly placing fertilized eggs in an incubator whose bottom portion is covered with a layer of medium sand whose thickness is 3cm, spacing distance between every two fertilized eggs is 1cm, after a layer of fertilized eggs is arranged, said layer of fertilized eggs is covered with one layer of medium sand whose thickness is 3cm, then laying second layer of fertilized eggs on said medium sand layer, and covering said second layer with another layer of medium sand whose thickness is 2cm, then placing said incubator in which two layers of fertilized eggs are held into an incubation room to make incubation; (B), controlling room temperature at 32-34deg.C, controlling humidity of sand and making it be 7-8%, at same time having good ventilation condition; and (C), after the incubation of fertilized eggs is reached to a certain temperature, taking out these fertilized eggs, placing them into a basin, then slowly pouring clear water with 25-30deg.C into the basin, soaking all the fertilized eggs, after several minutes, lots of young soft-shelled turtles can be incubated. Its incubation survival rate is up to 95%.
Description
Technical field
The present invention relates to the hatching m of a kind of ecological soft-shelled turtle, especially relate to the hatching m of a kind of Chinese soft-shelled turtle, belong to agricultural byproducts and culture the field.
Background technology
Soft-shelled turtle is a poikilotherm, the variation of environmental temperature is very sharp to external world, soft-shelled turtle egg broken shell survival rate is not high, the broken shell survival rate of present domestic conventional incubation technology is about about 80%, must be pointed out, selection of parent soft-shelled turtle and cultivation are the bases, the particularly hatching of Chinese soft-shelled turtle, because the basis of Chinese soft-shelled turtle hatching requires than higher, as the selection of close soft-shelled turtle: select for use the wild soft-shelled turtle in Taihu Lake as close soft-shelled turtle, behind the selectivity gland maturity 1 year, body weight more than 1 kilogram, healthy and strong, do not have and hinder, the back is shinny smooth, Quick off the mark, and the inside and outside does not have the male and female soft-shelled turtle of wound as close soft-shelled turtle; The cultivation of parent soft-shelled turtle: in same cultivation pond, the individual size of close soft-shelled turtle should be similar, and male soft-shelled turtle is slightly less than female soft-shelled turtle, only puts close soft-shelled turtle 300-350 in a suitable place to breed for every mu, and female-male proportion is 4: 1.The fresh animal forage that the protein content of throwing something and feeding is high, a day throwing feed is the 5-8% of soft-shelled turtle body weight in the pool.The parent soft-shelled turtle is cultivated and keeps water quality pure and fresh in the pond, and transparency remains on 30-40cm, and Ph is at 7.5-8.0, more than the dissolved oxygen 4.5mg/L.
Therefore say and to realize Chinese soft-shelled turtle large-scale ecological breed, at first should solve the not high technical barrier of soft-shelled turtle egg broken shell survival rate.
Summary of the invention
The present invention is directed to the above-mentioned technical problem that had embodied already, proposed a kind of not only reducing cost but also improve the hatching m of the Chinese soft-shelled turtle of incubation rate.
Technical scheme of the present invention is achieved in that the hatching m of a kind of Chinese soft-shelled turtle, and its operating process is:
1. look into ovum and receive ovum: look into ovum and promptly check whether be fertilized egg.Transport fertilized egg back hatching house, after transporting back, fertilized egg fitly is placed on filled up in the incubator of having gone up the thick sand of 3cm, the spacing of ovum and ovum is 1cm, behind discharging one deck, cover the medium sand of 3cm in the case, put one deck fertilized egg on it again, repave the 2cm medium sand then, move into the hatching house and put into the hatching of framework lattice.
2. the temperature and humidity of soft-shelled turtle ovum hatching: room temperature is controlled at 32-34 degree centigrade, and the sand humidity of hatching usefulness will be controlled at 7-8%, is furnished with the good aeration condition simultaneously.
3. with walking out of the shell method: accumulated temperature reaches 3.6 ten thousand degree in the hatching.Embryonic development is ovum completely, adopts the young soft-shelled turtle of artificial initiation to go out shell simultaneously.Concrete grammar is: incubating oosperm accumulated temperature reaches 3.6 ten thousand when spending, and these ovum that are about to out shell are taken out, and puts into basin, slowly pour 25-30 degree centigrade clear water into, flood whole ovums, after several minutes, have large quantities of young soft-shelled turtles and pip.
Advantage of the present invention is:
(1) method that has adopted three-dimensional placement to hatch has improved the availability of hatching the greenhouse.
(2) adopt the constant temperature hatching method, effectively shortened brooding time, improved incubation rate.
(3) adopted with walking out of the shell method, made young soft-shelled turtle neat specification unanimity, effectively raised the survival rate that young soft-shelled turtle is cultivated.
(4) the hatching survival rate reaches 95%.
Embodiment
The hatching m of a kind of Chinese soft-shelled turtle, its operating process is:
1. look into ovum and receive ovum: transport fertilized egg back hatching house, after transporting back, fertilized egg fitly is placed on filled up in the incubator of having gone up the thick sand of 3cm, the spacing of ovum and ovum is 1cm, behind discharging one deck, cover the medium sand of 3cm in the case, put one deck fertilized egg on it again, repave the 2cm medium sand then, move into the hatching house and put into the hatching of framework lattice.
2. the temperature and humidity of soft-shelled turtle ovum hatching: room temperature is controlled at 32-34 degree centigrade, and the sand humidity of hatching usefulness will be controlled at 7-8%, is furnished with the good aeration condition simultaneously.
3. incubating oosperm accumulated temperature reaches 3.6 ten thousand when spending, and these ovum that are about to out shell are taken out, and puts into basin, slowly pour 25-30 degree centigrade clear water into, flood whole ovums, after several minutes, have large quantities of young soft-shelled turtles and pip.
Claims (1)
1. the hatching m of a Chinese soft-shelled turtle, it is characterized in that: the operating process of this method is:
A, look into ovum and receive ovum: look into ovum and promptly check whether be fertilized egg.Transport fertilized egg back hatching house, after transporting back, fertilized egg fitly is placed on filled up in the incubator of having gone up the thick sand of 3cm, the spacing of ovum and ovum is 1cm, behind discharging one deck, cover the medium sand of 3cm in the case, put one deck fertilized egg on it again, repave the 2cm medium sand then, move into the hatching house and put into the hatching of framework lattice.
The temperature and humidity of B, the hatching of soft-shelled turtle ovum: room temperature is controlled at 32-34 degree centigrade, and the sand humidity of hatching usefulness will be controlled at 7-8%, is furnished with the good aeration condition simultaneously.
C, with walking out of the shell method: accumulated temperature reaches 3.6 ten thousand degree in the hatching.Embryonic development is ovum completely, adopts the young soft-shelled turtle of artificial initiation to go out shell simultaneously.Concrete grammar is: incubating oosperm accumulated temperature reaches 3.6 ten thousand when spending, and these ovum that are about to out shell are taken out, and puts into basin, slowly pour 25-30 degree centigrade clear water into, flood whole ovums, after several minutes, have large quantities of young soft-shelled turtles and pip.
