Incubation method
Select the appropriate size of the hatchery room, if the incubation of 50 kilograms of soil yuan eggs need an area of ​​6 cubic meters of space, the eggs and broiler eggs stir together, into the hatchery, with the beginning to warm up warming. Heating coal stove or electric stove, use coal stove humidification should pay attention to the use of pipelines to discharge gas outside hatchery, incubation chamber temperature is maintained at 28 degrees Celsius ~ 30 degrees Celsius, can not be ups and downs, relative humidity is maintained at 50 ~ 60%. A plastic box with a diameter of 60-80 cm is used. Each plastic box can hold 4 kg of eggs. It needs to be turned once or twice a day. It takes about 20-30 days to start a small insect, usually 43 days. When the earth egg pieces hatch through suitable environment, about thirty days later, the white larvae will emerge out of the shell. When the larvae crawl, the grazing soil sinks, the egg pieces float, or it is used to open many white larvae. The larvae can be screened out by separating the egg masses from the larvae with a 4 mm hole sieve, and then adding the preheated cultivating soil in the soil egg mass to mix well. The ratio is 1:1. Do not use any finer ones. Sieve the larvae, which will reduce the survival rate of the larvae. The screened bugs can be placed directly in the rearing tank for rearing. The rearing soil in the rearing pond should be thickened to about 12cm. The temperature and humidity should be the same as in the hatchery. The larvae placed in the rearing pond can be fed, and the wheat bran or pumpkin leaves can be fed directly. If you add a little bean flour to increase the nutritional effect will be better. Winter hatching larvae should pay attention to: feeding soil during the incubation period can not be sprayed, can only be replaced. Keeping the humidity of the cultivating soil and keeping it in a group is free to fall and scattered, and the temperature cannot be changed. The replenishing soil must be preheated. As long as you master these key methods, you can achieve 85% of the hatching rate in the winter, and the key to good soil is to hatch larvae.
