CATDOLL : CATDOLL:How to breed Chinese softshell turtles?

How to breed ground turtle?

To breed ground beetles, choose a container with smooth surroundings and a height of more than 15 cm to prevent them from crawling out. For small-scale breeding, pots can be used. Pay attention to the temperature and humidity. Bury half of it in the soil residue, and the height of the soil should be 40-50 cm. You can also use a flat pool to breed Sophora japonica, build a pool with cement, and cover it with plastic film to prevent moisture. This is more convenient to manage and the cost is not high.

Answer: 1. For pot culture, you can choose a plastic pot with a smooth inner wall, with a height of more than 15 cm and a diameter of more than 45 cm. You can directly culture it with the built-in breeding soil. The eggs can also be cleaned and incubated in a pot. The hatched...

Please tell me if you have ever done breeding: How to breed Chinese softshell turtles?

1. Breeding conditions: Earthworms like to live in dark, moist, loose soil rich in humus. They are very adaptable and can be raised anywhere as long as a certain temperature and humidity are maintained.

2. Three-dimensional factory breeding. The equipment used to raise earthworms is relatively simple, and plastic basins can be used for small-scale breeding. If you want to breed earthworms on a large scale, you can adopt a three-dimensional multi-layered breeding platform. The specific method is: lay bricks against the wall in the house, and the height of each layer should be about 30-38cm. It is best to use cement boards for the layer boards, and 5-7 layers of breeding platforms can be built on each wall. Practice has shown that this kind of breeding platform can make the indoor temperature 6-10℃ higher than that of a flat pool, and the growth and development of earthworms is significantly accelerated. It only takes about 7 months to complete a generation, and the annual output is significantly increased.

3. Feed configuration. Earthworms are omnivorous insects. They can be fed with anything that pigs can eat, such as wheat bran, rice bran, cake meal, green fodder, potatoes, vegetable leaves, bones, etc. They only need to be fed once every night. Earthworms are the most voracious food for earthworms, so they can be used in breeding.

4. Scientific management and artificial breeding of earthworms. Scientific management is the key to success. Mites are common parasites in breeding earthworms. The prevention and control methods are: trichlorobencarb and 20% mite egg ester powder, mixed with 1:400 times dilution into the breeding soil; you can also remove mites by replacing the breeding soil in time or using fried dough sticks, bones, and pumpkin flowers as bait.

2 types of egg hatchingEdit

Choose a plastic basin with a smooth inner wall (50-80 cm) in diameter and place 4 kg of eggs in it.

Earthworm breeding

Mix the eggs with 1/2 of the volume of the breeding soil, and keep the temperature of the breeding soil at about 40℃ (grab them into a ball, and they will break when they fall freely). The thickness of the soil in the basin including the eggs is 8-10 cm. The breeding soil should be prepared in advance and placed in the incubator for preheating. The temperature difference cannot exceed 5℃. During the incubation period, the temperature should be kept at 25-30℃ (the incubation temperature is preferably 28℃). Turn the eggs by hand 2-3 times a day. The movements should be gentle to avoid damaging the earthworm eggs. After 35-40 days of incubation, a large number of larvae will break out of the shells. At this time, the larvae can be screened out (with a 4 mm sieve). The screened eggs are mixed with the breeding soil again, and the larvae can be placed in a 10 cm thick breeding soil pool for breeding. The larvae should be screened every 2 days.

Note: The formula of feeding soil is: the topsoil in the vegetable garden is sieved with a 4mm sieve, mixed with 50% burnt rice husk ash and mixed evenly. If some livestock manure or crushed crop straw or sawdust is added, the feeding soil will be fertile and loosened better. The moisture of the feeding soil is such that it can be grasped by hand and will break into pieces when it falls to the ground.

During the breeding process of medicinal insects, many breeders called the large earthworm cockroach breeding base in China to ask how to know whether the seeds are good or bad when buying and selling eggs. Now our technicians will teach you a few tricks. The key is to choose the earthworm egg case with good quality: 1. The color should be brown or tan. 2. The appearance is normal and without deformity. The grains are large and full, the surface is shiny, and there are slight engravings. 3. The egg case is elastic when you gently pinch it with your hands. 4. Take the egg mass and look at it against the sun or light, and the egg grains in the sheath are clearly visible. The egg case of poor quality has mud on the surface, the serrated air holes have white edges, and the surface is dark and moldy. It turns white and dry after being pinched. And you, kind-hearted people, must open your eyes, distinguish the true from the false, and find a down-to-earth and real large-scale breeding company and breeding base. This is the premise for the success of insect breeding and the guarantee of getting rich. Choosing good earthworm breeding eggs for breeding earthworms is the premise and key to your success in breeding earthworms; if you choose cheap and low-quality earthworm eggs, the hatching rate will be low, and the earthworms that hatch will be small, have low disease resistance, and grow slowly, then it can be said that you have already failed halfway before you even officially embark on the road of breeding!

3. Introduction principles

Anhui earthworm breeding

Earthworm breeding is a part of the breeding industry. Like other breeding and planting industries, certain principles must be followed to ensure the success of earthworm breeding and minimize economic losses. Referring to the earthworm breeding experience of Hunan Yinong Technology, the following principles should be noted when introducing earthworms:

Regional Principle

The most advanced method of earthworm breeding is the three-dimensional constant temperature breeding method. This method has high economic benefits for breeding earthworms, but this is only for large-scale breeders. For customers who are just starting to breed earthworms, there is no three-dimensional constant temperature breeding if the earthworms are not yet there or are very small, so it is worth paying attention when introducing them. The earthworms in the south grow in the natural environment for a much longer time than those in the north, and they are more adaptable. Therefore, there is no regional difference when introducing them from the south to the north, just like transplanting plants from the natural environment to the greenhouse, the plants can also grow well.

Market principles

When introducing earthworms, there is a big difference between the price and quality in the market. Some beginner earthworm breeders actively introduce earthworm seeds when they see low prices, thinking that this way they can breed more earthworms and save money, but they must pay attention to the quality of seeds, which is the key. Some breeders believe that seeds with high prices and high recycling prices are good seeds, but they must pay attention to market principles. The market price of earthworms can be more accurately inquired in the medicinal materials market. Why are some recycling prices much higher than the market? This issue deserves the attention of beginner breeders. Therefore, when introducing earthworms, under the premise of following the two principles of region and market, finding down-to-earth large-scale earthworm breeders to introduce the species is the key to your breeding success.

4. Feeding and management

Larvae feeding and management

Larvae start to eat 2 days after hatching. At this time, they can be fed with some wheat bran, fruits, pumpkin flowers, small green vegetables, and pumpkin shreds. During the larval period, some nutritious food such as soybean powder, eggs, and milk can be added. Just sprinkle the feed on the surface of the breeding pool and keep the temperature at 25-43℃.

Feeding and management of Chinese worms

The management of Chinese insects is relatively extensive, and there are no special requirements for feed, as long as they can eat enough.

Feeding and management of egg-laying insects

Egg-laying worms require the soil to be 12 to 15 cm thick, and the feed requires a ratio of 50% green fodder and concentrated feed. If you can add a little soybean powder or animal meat scraps, it will be better to increase the nutrition of the earthworms. The feeding situation is that there is not much feed left on the surface of the earthworm pool by the next morning. The temperature in the breeding pool can be maintained at around 25℃, and the humidity is 60% to 70%. If the humidity is not enough, you can use a pesticide-free sprayer to humidify it, requiring small amounts and multiple times.

Three-dimensional high-density breeding technology

1. Stocking density and thickness of the soil

The thickness of the soil for 1-4-year-old earthworms is generally 2-3 cm. As the earthworms grow, the stocking density increases and the thickness of the soil should be gradually increased. The relationship between stocking density and humidity. If the density is too low, the earthworms will be less active and the soil will become compacted and unevenly dry and wet, affecting their growth (because the water needed for the growth of earthworms is absorbed by their own body surface). Those with severe water shortage will die. When a certain stocking density is reached, the humidity of the soil can be controlled evenly through the activity of the earthworms. Generally, one generation cycle can be completed in 6 months. The stocking density cannot be too high. Generally, when you tap the bottom of the pond with your hands and a wave-like wriggling pattern appears on the surface of the pond, it is the highest density. [1]

2. Stocking density and temperature

The stocking density requires 0.35kg of eggs per square meter (worm rate 70%-80%). When they grow to 4-5 years old, the temperature of the insect body can be used to control the temperature of the breeding room (the breeding room can be built according to the three-dimensional constant temperature method). Generally, 0℃ is the hibernation period and no heating is required; 0℃-25℃ is the unsuitable growth period; 25℃-32℃ is the most suitable growth period; and above 40℃ is the death period.

3. Stocking density and economic benefits

High-density breeding can save energy, expenses and increase production with the same investment.

4. Stocking density and feeding management

During feeding, it is appropriate to control the stocking density, which is beneficial for controlling the feeding amount and preventing leftover food or food shortage. It is also beneficial for maintaining constant humidity and ensuring normal molting of the earthworm.

5. Pest and disease control

Main pests

Mites[2]

Scrape off the surface layer of soil in the breeding pond, sift it out with a sieve (window screen sieve), and discard the soil. If there are some earthworms in the sieve, mix them with lime powder and put them in the earthworm pond. Do this once a day, and there will be basically no mites after 5 days.

Disinfection. Clean the ground, take veterinary trichlorfon tablets and dissolve them in 2000 times clean water, then spray the ground with the liquid for disinfection.

Taking advantage of the habit of earthworms to hide during the day and come out at night, place fried dough sticks and fried sugar on the feeding plate during the day to lure mites to eat. Take them out two hours later and treat them to kill them. Repeat this several times to reduce the damage caused by mites. If mites have multiplied in large numbers in the breeding pond and caused harm, the only option is to replace the breeding soil.

Natural Enemies

Earthworms have many natural enemies, such as rats, ants, spiders, chickens, ducks, cats, etc. The breeding pool should be sealed to prevent the entry of natural enemies. For spider control, vacuum cleaners can be used once a week.

Pesticide use

Be careful when feeding earthworms to prevent pesticides from contaminating the feed. Mosquito-repellent incense and pest control spirits are also fatal to earthworms and are strictly prohibited.

6 Harvest

Three months after Chinese earthworms lay eggs, the peak period of spawning has passed, and there are batches of deaths on the surface of the breeding pond. Choose sunny weather to harvest a large number of them at once, use a 1 cm mesh sieve to dig the earthworms out of the pond with the soil, sieve out the soil, put the sieved earthworms into boiling water to kill them, rinse them, and dry them in the sun. If it is rainy, you need to use the drying method. To check the dryness of the earthworms, you need to squeeze the abdomen of the earthworms by hand. If there is no soft material in the abdomen, it is a dry earthworm. The dryness rate of earthworms is 43%. Dried earthworms can be sold. The quality requirements are large, dry, free of impurities, and not moldy.

7 Breeding room structure

Cement board

The aisle of the breeding house is generally not less than 70 and the widest is no more than 1 meter, because we have to step on it to operate and manage. If it is too wide, the span is too large and it is not easy to operate. If it is too narrow, we can turn around and it is inconvenient to do anything. Generally, it is between 70 and 1 meter. This kind of three-dimensional breeding not only reduces the construction cost and significantly improves the work efficiency, but also saves the management cost.

This three-dimensional farming method means that one person can normally manage a 400 square meter farming area. If it is the original farming method, one person can only manage 100 square meters. In comparison, 400 square meters can save the labor of three people. That is to say, the wages of three people are saved. The minimum wage of three people is 30,000 yuan, and this 30,000 yuan is all net profit.

Asbestos Tile

Asbestos tiles can completely replace the prefabricated panels under the cement pool. The construction cost is reduced by half compared to the cement pool, only 25 yuan per square meter. Not only is the cost low, but the construction is also faster.

The prefabricated panels used before were generally 3 cm, 2.5 to 3 cm thick, but it was about one square meter, which means it was quite difficult for two people to lift it. In the past, using cement prefabricated panels, three people could only build 30 to 40 square meters of aquaculture ponds in a day, but now using asbestos tiles, they can build about 100 square meters in a day.

If we use plastic basins, this 20-square-meter house can raise fish in an area of ​​50 square meters, but the cost is about 3,000 yuan. If we use cement pools, we can raise fish in an area of ​​100 square meters, and the cost is about 5,000 yuan. Later, we improved the asbestos tiles, which can also raise fish in an area of ​​100 square meters, but the cost is about 2,500 yuan, which is enough, including the labor cost.

8 Selection of earthworms

(l) The egg sheath of the good quality earthworm is brown or tan in color, without any deformity, large and full, shiny with slight engravings on the surface, and is elastic when pinched by hand. The eggs inside the sheath can be clearly seen when viewed in the sun or under a lamp. White milky pulp can be seen after being crushed.

(2) The surface of the eggs of inferior earthworms is shriveled or moldy, and the eggs are rigid and cannot hatch. After crushing, no white fresh milk can be seen, and the eggs are all shriveled. Those with a yellow-green surface are all inferior eggs.
