Requirements of incubation environment for breeding geese
Small-scale wild goose farms can allow geese to hatch on their own, or they can be hatched by goose. Large-scale wild goose farm needs to be hatched artificially, and the incubation period is 31 days. Fresh breeding eggs with suitable size, normal shape, color and clean surface were selected and sterilized with formaldehyde fumigation (15 grams of potassium permanganate per cubic meter, 30 ml of formaldehyde at 24 ℃-27 ℃ at room temperature), then preheated in the incubator (22 ℃-24 ℃) for 8 hours and then hatched.
The temperature of wild goose was 38.3 ℃-39.0 ℃ in the early stage, 37.5 ℃-38.0 ℃ in the middle stage and 37.0 ℃-37.5 ℃ in the later stage.
Humidity: the relative humidity is 75%, 80%.
Turn eggs: turn eggs every 3 hours, turn eggs at an angle of 90 degrees, turn eggs gently, steadily and slowly, so as not to cause rupture of blood vessels in yolk membrane, separation of allantoic chorion and eggshell membrane, causing embryo death.
Cold eggs: in the later stage of incubation, cold eggs are cooled for 2 ℃ 3 times a day, and the temperature of cold eggs is 25 ℃ ~ 27 ℃. If the room temperature is too low, the development will be affected by "flashing eggs".
Illuminated eggs: the eggs need to be illuminated twice in the process of hatching. on the 8th and 28th day after hatching, the azoospermic eggs and middle dead eggs were detected, and the embryonic eggs were moved out of the machine after the second irradiation. The hatching begins on the 30th day and ends on the 31st day.

Countermeasures for breeding soft-shelled turtle in outer pond in high temperature season
In the process of ecological soft-shelled turtle breeding in outer pond, high temperature season is the key stage. During high temperature period, soft-shelled turtle feeds a lot and grows fast. However, it is also the peak period of disease outbreak. If the management is not good, it will cause significant economic loss to the farmers. Therefore, if the high temperature season is done well,
