Embodiment 1

[0017] A method for hatching the frog eggs of the black-spotted frog, comprising adding the extract solution of the jellygrass jelly to water in a mass ratio of 1:20, and then adding it to a hatching pond, and then putting the frog eggs of the black-spotted frog into the hatching pond for hatching at 20°C.

[0018] Further, the extract of the jelly grass accounts for three-quarters of the volume of the hatching pond after being watered.

[0019] Further, the jelly jelly extract is obtained by a microwave-assisted lye extraction method.

[0020] Further, the preparation method of the Herba jelly extract is:

[0021] Mix jelly jelly and aloe vera in a mass ratio of 5:1.2, pulverize, pass through a 100-mesh sieve to obtain a powder, add 12 times its mass of clear water to the powder, and stir for 20 minutes at a speed of 1200r / min to obtain a mixed slurry, and then use Adjust the pH of the mixed slurry to 8.9 with sodium carbonate, heat to 60°C, extract under 350W microwave for ...

Embodiment 2

[0027] A method for hatching the eggs of the black-spotted frog, adding water to the extract solution of the black-spotted frog in the hatching tank after adding the extract solution of the jellyfish at a mass ratio of 1:20, and then putting the frog eggs of the black-spotted frog in the hatching tank for hatching at 22°C.

[0028] Further, the extract of the jelly grass accounts for three-quarters of the volume of the hatching pond after being watered.

[0029] Further, the jelly jelly extract is obtained by a microwave-assisted lye extraction method.

[0030] Further, the preparation method of the Herba jelly extract is:

[0031] Mix jelly jelly and aloe vera in a mass ratio of 5:1.5, pulverize, pass through a 100-mesh sieve to obtain a powder, add 15 times its mass of clear water to the powder, and stir for 20 minutes at a speed of 1200r / min to obtain a mixed slurry, and then use Adjust the pH of the mixed slurry to 8.9 with sodium carbonate, heat to 65°C, extract under 35...

Embodiment 3

[0037] A method for incubating the eggs of the black-spotted frog, comprising adding the extract solution of Herba japonicus to water in a mass ratio of 1:20, and then adding it to a hatching pond, and then putting the frog eggs of the black-spotted frog into the hatching pond for hatching at 21°C.

[0038] Further, the extract of the jelly grass accounts for three-quarters of the volume of the hatching pond after being watered.

[0039] Further, the jelly jelly extract is obtained by a microwave-assisted lye extraction method.

[0040] Further, the preparation method of the Herba jelly extract is:

[0041] After mixing jelly jelly and aloe vera in a mass ratio of 5:1.3, pulverize and cross a 100-mesh sieve to obtain a powder, add 13 times its mass of clear water to the powder, and stir for 20 minutes at a speed of 1200r / min to obtain a mixed slurry, and then use Adjust the pH of the mixed slurry to 8.9 with sodium carbonate, heat to 62°C, extract under 350W microwave for 25 ...

Abstract

The invention discloses a rana nigromaculata spawn incubation method, and relates to the technical field of culture. The method comprises the steps that a Chinese mesona herb extracting solution is mixed with water in a mass ratio of 1:20 and then added into an incubation pond, and then rana nigromaculata spawns are placed in the incubation pond for incubation at the temperature of 20-22 DEG C. Bymeans of the rana nigromaculata spawn incubation method, the activity of the rana nigromaculata spawns can be maintained for a long time, and along with development of the rana nigromaculata spawns,active components in the Chinese mesona herb extracting solution can improve the incubating rate of the rana nigromaculata spawns and the environmental adaptive ability of tadpoles; the spawns can beautomatically divided into vegetal poles and animal poles, the phenomenon of pile death in a cluster of spawns is avoided, the incubating rate is high, and the incubating rate reaches 96% or above.

Description

technical field [0001] The invention belongs to the technical field of cultivation, and in particular relates to a method for hatching eggs of black-spotted frogs. Background technique [0002] The black-spotted frog is a very common frog, belonging to the frog family, anura, and amphibians. The black-spotted frog has tender meat, less fat, low sugar, and high protein content. It has the effects of clearing away heat and detoxification, reducing swelling and relieving pain. The artificial breeding of black-spotted frog is not only simple in technology, but also has fast economic benefits. Therefore, the breeding of black-spotted frog is an aquatic product. Breeding hotspots. [0003] The breeding of black-spotted frogs includes the selection of species of frogs, the cultivation of species of frogs, the fertilization of eggs, the hatching of frog eggs, the raising of tadpoles, the management of young frogs and the management of adult frogs, wherein the hatching of frog eggs ...
