Difference between Perilla frutescens and Perilla frutescens
The budgerigar raised artificially is very good at dismantling cages because of its hard mouth shell and flexible climbing with toes and sharp mouths. Therefore, it is advisable to build suitable cages and raise them with solid houses and metal nets. The room temperature should be kept at 5 ~ 10℃ in winter. In the southern cities of China, the temperature is not lower than 0℃ in winter, and budgerigars can be bred in open cages. A small amount of breeding in the family, you can choose the right box cage, breeding and breeding effect is very good. Cages should have enough habitats for them to climb and live, and the ground or bottom of cages should be padded with fine sand for sand bathing and feeding. The feeding room needs good ventilation and sufficient light. A large number of budgerigars fed in groups drink a lot of water, so birds often excrete feces while drinking water, which often pollutes their drinking water. Therefore, it is best to use the automatic drinking machine used by poultry to supply water, so that you can not bathe in the water and keep the drinking water clean.

The feed ratio is: 7 parts of millet or millet, 2 parts of barnyard grass, and 0/part of perilla seed/kloc. This mixed granular material is suitable for feeding all kinds of parrots, plus mineral feed, such as squid bones and shells.

Captive budgerigars lay eggs in dark light and hatch in nests. If the light in the nest is too strong, the hatching effect is not good. Usually, the artificial nest box consists of an inner nest chamber and an outer nest chamber, the outer nest chamber has a nest opening leading to the cage, and the partition plates between the inner nest chamber and the outer nest chamber are communicated with each other through holes. The inner nest room is covered with sawdust or fine sand, which is the place where females lay eggs and hatch. The reference dimensions of the nest box are: the inner nest room and the outer nest room are 16 cm (length) × 16 cm (width )×16 cm (height) respectively; The diameter of the nest mouth is 5 ~ 6 cm, and the lower edge of the nest mouth is 6 ~ 7 cm away from the nest bottom.

Beijing breeds budgerigars in autumn, winter and spring every year. In summer, due to the hot climate, continuous nesting and hatching not only affect the health of parents, but also significantly reduce the rate of hatching and brooding, so young birds are generally unhealthy, so they generally stop breeding in summer. The prevention and control method is to take out the nest box in the breeding cage from July to September every year, clean and disinfect it, and hang it again after 10 months.

From June 65438 to June of the following year, budgerigar can lay eggs and hatch for 3-4 nests. Each nest lays 4-7 eggs, with a maximum of 10, pure white shell, egg weight of 2.5g, and incubation period of 18 days; The chicks stay in the nest for 34 ~ 38 days, and begin to live independently around 40 days old. Young birds are sexually mature at 6-8 months and begin to mate and reproduce. The best mating age is 1 ~ 5 years old.
