The Greenhouse Film Electric Roll-Up Unit replacing traditional manual roll-up unit to reach high speed automation in revolving & releasing films and greenhouse environment, it is the new generation of greenhouse ventilation and temperature regulation facilities. Portability, output torque, output lock, wide range and precise adjustment, waterproof, dew-proof and power-saving are the key characteristics for Electric Roll-Up Unit, which is the best choice for modern daylight greenhouse applied in different climates.

鹧鸪 4.5 to 5 months of age reach sexual maturity, and the age of breeding begins is 180-225 days. At this time, the female pupa starts production. Generally, the sexual maturity of females is 2-4 weeks, and the ratio of male to female is free-range. 1: (2-3), when caged 1: (3-4) adopts the method of free mating, the fertility rate of hatching rate is relatively high, the fertilization rate is generally 92%-96%, and the hatching rate is 84%-91%. Density usually 4-5 per square meter.
Second, hatching eggs Select egg shape is normal, the size is moderate, and meet the species requirements of the eggs into the 0.2% benzalkonium chloride solution (temperature 30 °C) soak 1-2 minutes into the incubator, pay attention to the incubation chamber temperature will affect the incubator The temperature is therefore kept indoors at 20-25°C. Can not be lower than 14 °C, while the temperature in the incubator should be (1-7 days) 38 °C, (7-16 days) is 37.8 °C, (17-24 days) is 37.7 °C, usually 23 days to hatch After the disc uses 37.7 °C conditions. (General incubation period is 24-25 days)
Third, the chicken's heat preservation and physiological characteristics:
Newborn quail only weighs between 13 and 14 grams. It has poor adaptability to the external environment and poor resistance. Therefore, rag or wrinkle toilet paper should be applied to the bottom or raised floor of the cage in order to benefit the young. Stand or walk, and prevent umbilical cord infection, chicks are timid, frightened and slightly disturbed, can easily cause emotional stress and scurry, or even refuse to eat, causing unnecessary losses, so pay attention to keep the surrounding environment quiet and careful Perform all operations, and pay special attention to the ability of the chicks to fly in the early stages of growth and development. Generally starting from the age of 2 weeks, precautions should be taken to prevent them from fleeing. The insulation of the chicks is similar to the insulation of other rare birds but it is important to note that It has a good clustering characteristics, like the accumulation of room hill-style sleep. However, it must be distinguished from the phenomenon of beating piles due to cold. The former sleep posture is natural, and the whole body is stretched while the latter is necked, hidden, and closed.

V. Epidemic prevention and control:
First of all, environmental health should be drafted, immunized with 7 days of age with Newcastle disease, Lasota vaccine drinking water, 16 days of age immunized with a new double-combined attenuated vaccine drinking water, 25 days of age with a new branch of double oil emulsion vaccine intramuscular injection, about 50 days of age Intramuscular injection with infectious rhinitis oil emulsion vaccine.
