孵化技术（Incubation Technology） Our school practice base by EI card intelligent incubator, batch incubation of Rhine goose eggs, hatching rate of fertilized eggs reached 88%. Some technical points of artificial hatching of Rhine goose eggs are discussed for reference. The characteristics of 1. smart card EI incubator EI smart card incubator hatching machine and two machine body young, can automatically adjust the temperature, ventilation, egg turning and humidification. But the humidifying effect is not ideal, so in the process of hatching, according to the actual humidity, the living spirit adds wet cloth to the incubator and the chick, and sprays warm water to the machine regularly. The egg cart has a chute which can pull and push the egg cart along the slipway. Preservation and placement of 2. eggs The preservation time of the eggs is closely related to the temperature. When the temperature is constant, the shorter the storage time, the higher the hatching rate; on the contrary, the hatching rate is lower, and the incubation period will be extended. When the environment temperature is 18 degrees Celsius, the preservation period within 4 days for egg incubation, hatching rate of fertilized eggs was 97%; if only after 4 days of incubation, hatching rate will exceed 1 days per 2% to 4% decline, so choose fresh egg incubation is very important. When the eggs are stored, they are placed horizontally, and no abnormal embryonic development is found. 3. temperature control (1) the eggs pre temperature because of Rhine goose egg shell membrane, eggshell, pores and inner and outer membrane of the special structure of the initial incubation, egg slow heating, therefore before incubating eggs should be 36 ~ 38 DEG C preheating 6 ~ 8 hours after incubation, reentry is appropriate. (2) the suitable temperature heating slower in the early because the eggs in late because of the relatively high rate of fat, produce a lot of heat physiological special structure, egg, embryo lead to d
