What kind of food does Tu Yuan eat?

Tuyuan scientific name soft-shelled turtle, also known as turtle worm, hillbilly, cross the street, turn dung bug, soil fertilizer yuan, etc., often in the old soil housing wall root of the soil activities, for the market shortage of traditional Chinese medicine, with the destruction of the natural environment, as well as the annual expansion of domestic and foreign market demand, especially famous for its excellent quality, let's take a look at what food Tuyuan eats!

What kind of food does Tu Yuan eat?

Tu Yuan is an omnivorous insect, preferring fresh food, wheat bran and rice bran, followed by corn flour, shredded grains, peanut cake, soybean meal, miscellaneous fish, meat and all kinds of green grass leaves, melon peel, chicken, cow dung and other coarse materials, such as grass and other feed for slow growth, the full price can be fed with 72% wheat bran, 20% corn flour, 5% bean cake, 3% animal feed (cooked feed). Add 30% green vegetables or melons and fruits and feed them with full-price feed for 5 to 6 months, and the individual can grow into adults.

The growth cycle of soil element

Tu Yuan is an incomplete metamorphosis insect, the phenomenon that the insect changes from larva to adult state is called metamorphosis. Incomplete metamorphosis means that the larva (nymph) hatched by egg is similar to the adult in morphology and living habits, but the wing of the nymph is not fully developed, the body is not yet grown, and the reproductive system is not yet mature. After each molting, the wings and reproductive organs gradually develop and grow, and finally grow into adults. The completion of a generation needs to go through three stages: egg, nymph and adult. it takes about 8 months for the male to grow wings, and it takes about 9-11 months for the female to mature. The male dies 5-7 days after mating, and the female can lay eggs a week after mating, and once mating for life.

Culture techniques of Tuyuan

1. Feeding conditions: soil element lives in dark, moist, humus-rich loose soil, afraid of sunlight, latent during the day and active at night. The optimum temperature for growth is 28-30 ℃. When it is lower than 0 ℃ or higher than 38 ℃, it will cause a large number of death of adults and nymphs. When it drops to 8 ℃, it will stop its activity and enter the dormant period. Breeding should be based on the scale of breeding, regardless of size, a variety of forms, breeding can be cylinder culture, pit (pond) breeding, basin breeding, cabinet breeding, box breeding and so on.

2, breeding facilities: the equipment used for raising soil yuan is relatively simple, and plastic pots can be used for small-scale breeding. If you want to raise soil yuan on a large scale, you can take the way of three-dimensional and multi-layer feeding platform and build bricks against the wall in the house. The height of each layer is about 30cm. The laminate had better use cement board, and each wall can build a 5-storey 7-story feeding platform. The practice shows that this kind of feeding table can make the indoor temperature 6 ~ 10 ℃ higher than that of the flat pond, and the growth and development of soil element can be accelerated obviously. it only takes about 7 months to complete the first generation, and the annual output is significantly increased.

3. Raising soil: in winter, choose humus-rich, loose and fertile garbage mud, vegetable garden soil, ditch mud, stove foot soil, sand, loam, etc., mix in 20% of chicken manure, pig manure, coke ash or plant ash, and expose them in the sun. The nymphs and adults above 9 years old are 7 cm and 26 cm, respectively.

4. Temperature and humidity: the suitable environmental temperature for soil growth is 25: 30 ℃, more than 10 ℃ to start foraging, less than 10 ℃ to sneak into the soil for hibernation, and-5 ℃ will die. Therefore, some warm materials such as rice straw and chicken feathers should be put in the pond in winter and cleared out in time during the foraging period the following year, and the relative humidity should be 75-80%.

5. Feed configuration: Tuyuan belongs to omnivorous animals, animal feed includes earthworms, crickets, mole crickets and various animal scraps, etc. Plant feed includes wheat bran, rice bran, cake, powder, bean curd residue, corn, broken rice and green vegetable leaves, vegetable leaves, pumpkin flowers, mulberry leaves, melon peel and so on.

6. timely division: in the process of breeding, the mother soil element often eats the larvae and eggs, so when the larvae can forage on their own (refers to more than the 5th instar nymph), the mother soil element should be put into another pond in time, at the same time, the larvae should also be raised in different stages.

7. Feeding density: 1.5 kg of adults, 0.15 kg ~ 0.5 kg of 1st ~ 3rd instar nymphs, 0.6 kg ~ 1.2 kg of 4th ~ 6th instar nymphs and 0.6 kg ~ 0.9 kg of over 6 instar nymphs can be reared per square meter.

8. Feed the larvae: the juvenile nymphs mainly refer to the 1st and 4th instar nymphs, which are small and weak, so they should be based on concentrate, and the feed can be evenly scattered on the surface of the fodder soil, then rake the soil deeply into the central soil by hand, and mix the feed into the surface of the soil. and pay attention to prevent escape.

9. Scientific management: scientific management of soil element in artificial breeding is the key to success. Mites are common parasites in soil element breeding. Control methods can be mixed with triclofenac sulfone and 20% acarate powder into the breeding soil with a dilution of 400 times. Mites can also be eliminated by changing the breeding soil in time or using Youtiao, bones and pumpkin flowers as bait.
