I. Variety selection蚯蚓 Artificial breeding should be based on varieties with rapid growth, strong fertility, wide adaptability, long life, and easy domestication, such as Beixing II and Daping II.
Second, breeding methods in the outdoor sunny, humid, can irrigation drainage area 1.2 meters wide breeding tanks for breeding. Between the box and the box is a groove with a width of 0.4m and a depth of 0.4m. First fill in the middle of the box 1 meter wide, 20 centimeters thick fermented bait, and then put 3 cm thick and put a baby bait. The stocking densities of earthworms are generally about 5000 seeds per square meter, about 30,000 per month for 1-month-old pupae, and about 20,000 per square meter for hatching. Breeding began when the temperature was above 15°C, and the tank was moved indoors when the temperature dropped to 10°C. Wooden boxes, cartons, barrels, etc. can also be used directly for indoor breeding. This method is generally used for small farmers.
Third, the bait production will be straw, weeds, sugar cane bagasse, etc., chopped, plus pigs, cattle, chicken manure, stacked into a high cone conical shape, and then covered with straw or plastic film fermentation. If the raw material is too dry, water should be sprayed until the hand squeezes a small amount of water droplets. After 5 days, when the material temperature rose to 70°C, the material was turned over 1 times to facilitate uniform fermentation. After a few days, the water was sprayed and turned once. After 3 weeks, the bait fermentation was completed. Ideal bait should be dark brown, no odor, loose, and not sticky. First, test the quail with a small amount of fermented bait, if there is no adverse reaction, then feed it in large quantities. 4. When managing each feeding, first gently scrape the surface of the worm droppings (the worm's droppings are on the surface of the bait), concentrate the remaining bait and quail on one side, and add a new layer of bait again. Cover the material with new material. Regular turnover is an important task for breeding quail. Every two weeks, the top and bottom layers of the breeding box should be turned over one time to facilitate ventilation. The specific method is to remove the excrement first, and then turn the upper and lower material pairs to turn. Finally, Feeding. Outdoor breeding should pay attention to maintain the humidity inside the box, it is necessary to cover the rain in heavy rain.
