Tuyuan is rich in nutrients and has certain edible value. Therefore, besides medicinal use, Tuyuan is also used as a special food for human consumption. Now, the main points of edible Tuyuan breeding technology are introduced as follows:
1. Characteristic and food of human edible earthen element. Tuyuan grows in the soil, like dark and humid, day and night to forage, it has strong hunger resistance, half a month without food and physical impact, is a hibernating insect. It eats a wide range of vegetables, fruit peels, plant leaves, grain and oil waste and so on are its good food. Feeds should be mixed with water and wet, and fed once a day. Feeding amount should be kept on the surface the next day. The daily eclipse of Tuyen is about 5 kilograms per hundred kilograms.
2. Temperature control. The suitable temperature for normal growth of soil element is between 15-35 C, and the hibernation temperature is below 15 C to 0 C. Artificial rearing soil element can be fed in all seasons of the year by heating only 15-35 C.
3. Humidity control of cultivated soil. Raising soil elements can be carried out in brick ponds, which are 36 centimeters high and unlimited in length. They are separated by asbestos tiles or cement prefabricated boards, and can be constructed up to 8-9 layers to make full use of the space area for multi-layer three-dimensional breeding. Soil element has wide adaptability, strong disease resistance, and is not easy to get ill. But when the pond is dry, it is easy to cause molting. Therefore, spraying water with sprayers will also affect the normal growth of soil elements and cause big belly disease easily. Rats and chickens are natural enemies of Tuyuan, so we should close doors and windows and pour cement into the ground to prevent such natural enemies from invading. Ants are also harmful to the soil element. They can be brought out by cooked bones and eliminated.
