How to raise Tu Yuan Culture technique

Tuyuan is what we often call the soft-shelled turtle, which is distributed in many places in our country at present, and it is a common insect in our life. The value of Tuyuan is very high, so now many people have begun to raise it. However, before breeding, more people must want to have an in-depth and comprehensive understanding of its breeding technology.

How to raise 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.

Tuyuan culture technology

1. Divide the larvae at the right time: in the process of breeding, the mother soil 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 should be put into another pond in time, at the same time, the larvae should also be raised in stages.

2. 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.

3. 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 layer of the soil. and pay attention to prevent escape.

4. 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.

What kind of food does Tuyuan 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.

Soil element disease and its control

1. Green mold. Mainly occurs in the plum rain season, the turtle worm (Tuyuan) sick abdomen is dark green, with spots, the whole body is soft, loss of appetite, soon climbed out of the mud and died. Once the disease is found, the disease and insect will be kept in isolation and replaced with dry pit mud to reduce the density. At the same time, spray the worm with 0.5% formalin solution; you can also mix 0.25 grams of erythromycin into 0.25 kilograms of wheat bran and feed it 2 times for 3 times until cured.

2. Aspergillosis of egg mass. Due to the high temperature and high humidity in the jar (bowl), Aspergillus multiplied in large numbers, resulting in the death of eggs and nymphs. The prevention and treatment methods are as follows: keep the pit soil dry, the humidity does not exceed 20%, collect the egg block once every 10 days, mix 1 part of 3% bleach powder and 9 parts of lime powder, and sprinkle it on the egg block for disinfection. After emergence, the larvae were screened out every 3 days and reared in the larval tank. No feeding during the incubation period.

When breeding, Tuyuan must do a good job in selecting the location of the breeding land, and then choose the appropriate soil for breeding. When breeding, the choice of feed is also very important, in addition, we also need to strengthen its disease prevention and control, so that it can grow more healthily.
