Soil element growth cycle

The growth cycle of soil element is 8-9 months, and the completion of a generation needs to go through three stages: egg, nymph and adult. it takes about 8 months for males to grow wings, 9-11 months for females without wings and 9-11 months for maturation. Males die 5-7 days after mating, females can lay eggs one 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 multi-layer feeding platform and build bricks against the wall in the house. The height of each layer is about 30-38 cm. The laminate had better use cement board, and each wall can build a 5-7-story feeding platform. The practice shows that the indoor temperature of this kind of feeding table is 6-10 ℃ higher than that of the flat pond, the growth and development of soil element is obviously accelerated, and it only takes about 7 months to complete the first generation, and the annual output is significantly increased.

3. Raising soil: in winter, choose garbage mud, vegetable garden soil, ditch mud, stove foot soil, sand, loam, etc., which are rich in humus, loose and fertile, and mix in 20-30% chicken manure, pig manure, coke ash or plant ash. The ages of 1-4 years old, 5-8 years old, nymphs and adults are 7-10 cm, 16-20 cm, 20-26 cm and 20-26 cm respectively.

4. Temperature and humidity: the suitable environmental temperature for soil element 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 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 young nymphs mainly refer to the 1-4 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 about 2 cm deep 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.

The above is the introduction of the earth yuan growth cycle, I hope it will be helpful to you.
