Winter Breeding and Heating Technology

The optimum temperature for artificial breeding is about 30°C. If the temperature drops below 10°C, you will not eat or drink, stop growing, and go into hibernation. Therefore, it is of great significance to adopt warming measures to prevent hibernation. First, the use of hot water or thermal power plant thermal heating. Hot spring water contains sodium, potassium, bicarbonate and various trace elements, which are conducive to the growth of earthworms. After adjusting the temperature of the water in the raising pond to 30°C, it will not only avoid hibernation, but also will increase the weight quickly. If there is no hot spring water, the waste heat water of thermal power plants can also be used for warming. Second, the use of solar heating. The use of closed solar water heaters, circulating solar water heaters, or mobile solar water heaters, and then equipped with air-conditioning equipment can keep the water temperature of the rearing ponds at around 30°C during the winter. In this way, in the case of feeding 20 to 30 juveniles per square meter area, after 6 to 7 months of breeding, each cockroach can weigh about 130 grams, and then the stocking density is reduced to 6 per square meter, After another 10 to 15 months, each can weigh more than 0.5 kg and the largest can reach 1 kg. Third, heating with electricity, oil or gas. A double plastic greenhouse or steam heating device can be used to keep the water temperature of the rearing pond at about 30°C throughout the winter. If the stocking density is about 13 eggs per square meter, after one year of feeding, each can reach about 0.5 kg, reaching the market specification. The first of these three heating methods is the best, because the use of hot water or thermal water from thermal power plants to warm the water within the pond is simple, easy to control, low cost, significant results, where the conditions are preferred consider.
