The appropriate temperature for hatching is the most important condition for hatching. Only at the appropriate temperature can the normal material metabolism and growth of the embryo be guaranteed. The suitable incubation temperature is 37.5°C to 37.8°C. Can be used thermostat incubation method for temperature: 1 to 19 days for the 37.8 °C, 20 to 21 days for 37.5 °C. The temperature in the incubation chamber is required to be 22°C to 26°C. If the room temperature is low and cannot be increased, the incubation temperature should be raised from 0.5°C to 0.7°C; if the room temperature is high and cannot be decreased, the incubation temperature should be reduced from 02°C to 0.6°C. Before hatching, try warming and tempering so that the temperature in each part of the incubator can be evenly closed to the standard. Incubation should always check the hatching condition so as to adjust the temperature in time. When batch hatching, new and old eggs should be placed at intervals so that the temperature is uniform. In order to eliminate the increase in the number of laps during incubation to adjust the temperature.

Maintaining Ventilation Ventilation Ventilation is of utmost importance, especially in the late post-harvest period, where embryonic metabolism is enhanced, heat production is increased, and oxygen demand is high. At the time of hatching, the inlet and outlet vents of the incubator were all closed in the first week, and they were all opened 1/3 at the 7th embryonic age, 1/2 at 10 embryos, and 2/3 at 12 embryonic days, respectively. At the beginning of the three weeks, the vents were all opened. However, the incubation chamber temperature should be maintained at 20-25. Normally, after the eggs are laid and the dish is poured, all the inlet and outlet vents are closed, and when the temperature rises back to normal, the stomata is restored to the level that should be closed and opened.

Seizing the critical period 1~7 embryos and 18~21 embryos are two key periods in the incubation. In the early stage, eggs can be taken after hatching, the incubation temperature can be increased by 0.3°C~0.5°C, the incubation humidity should be 65% ~ 70%, the relative humidity of the incubation chamber should be 75%, the ventilation should be increased, and the turntable should be carried out at 19 embryos. ; 1⁄2 of the chicks hatched for the first time after hatching, pay attention to the treatment of chicks after hatching.

The vision training equipment includes the annular vision training system, which helps students to establish the concept of coordinate axis and Angle, enhance the vision field and the eye movement ability, train the visual cognition and visual tracking, and is conducive to the rehabilitation of low vision caused by amblyopia.
