2), preparation hatch soil: 4 kilograms on native first pieces of an egg are positioned in 75 centimetres of plastics circles of diameter basin, admix 3 kilograms of hatch soils, hatch soil is crossed 8 mesh sieves, through being preheated to 25 ℃-28 ℃, hatch soil is formed humidity 45% by soil 50% and ash 50%, hatch soil in advance polygamy system some be placed on the hatching room in preheating, with the woven bag splendid attire of band inner membrance, fasten sack, be 1 meter away from burning things which may cause a fire disaster more than.

3), merogony is grown in training: the temperature in hatching initial stage hatch soil and pieces of an egg remains between 25 ℃-28 ℃, the continuous development growth of pieces of an egg meeting, the pieces of an egg air-vent constantly sucks the moisture content of hatch soil, just can drying be canescence through 3-4 days hatch soils, with 8 mesh sieves hatch soil is sifted out, admix through the new hatch soil of preheating and mix thoroughly, can be mingled with larva that part gone out shell in the hatch soil of the soil that sifts out and directly to put into and raise the pond and begin to raise;

4), stir pieces of an egg: each once stirs pieces of an egg sooner or later to need every day between the incubation period, and the hatching pieces of an egg meeting through 20 days obviously increases full, illustrates that merogony is normal, through hatching in 35 days, has the appearance of part acarid in the hatching basin, belongs to normal phenomenon;

5), go out seedling: through hatching in 40-43 days, pieces of an egg can be large quantities of go out seedling, at this moment need to sift out every day larva, and trick wants light during the sieve larva, on a small quantity repeatedly, sifted out larva and connected hatch soil and put into and raise the pond, raised the pond for every square metre and can put 100,000 larvas in a suitable place to breed;

6), sieve is got larva: sieve should carry out in the hatching house when getting larva all the time, temperature during large quantities of emerging in the hatching basin should be promoted between 28 ℃-30 ℃, remain balance, can hear the pieces of an egg ghost sound that larva when sieve is got larva, at this moment should winnow with a dustpan the pieces of an egg ghost;

7), remove ghost: through 45-55 days, hatching was emerged and is finished substantially, and also having the part pieces of an egg can not emerge, and through hatching in 60 days, removed the ghost after emerging, and the remaining pieces of an egg of not emerging are compared with the pieces of an egg volume before the hatching, the calculating emergence rate.

Adopt the present invention, all can emerge throughout the year, the temperature balance in temperature balance in the hatching room and the hatching basin, the larva physique that hatching is come out is strong, and survival rate can reach more than 90%, for later raising is laid a solid foundation.Avoid the peak period of hatching, emerging, product price height, simple and convenient management is saved the labour.

Embodiment

Incubation method of earth yuan eggs may further comprise the steps:
