Indoor rack type two-layer hatching turtle seedling technology

Cultured turtles are another special breeding project for the special aquaculture industry in the next 10 years. At present, artificial breeding of turtles will be promising in Guangdong and even southern China. Turtles have good ornamental, edible and medicinal values. More and more widely known and concerned by people, a new round of consumer heat will be formed. Due to the moderate price of turtles, it has broadly entered the homes of ordinary people. At the same time, the demand for numerous restaurants and restaurants is also increasing, and the market conditions are promising. Xingning City Xiangyang turtle breeding farms, turtles have more than a dozen spring and autumn, has accumulated a wealth of experience in raising turtles. We visited his turtle farm. He introduced us to the entire process of raising turtles. He has 5,000 square meters of farmed area and has more than a dozen of snapping turtles, Brazilian turtles, Chinese tortoises, and yellow-throated turtles. Variety. This year, there are 10,500 snapping turtles, 12031 colorful turtles, 115,000 Chinese turtles, and 120 money turtles. Together, they have 258,210 eggs and 245,930 hatches. The hatching success rate is 95%. His hatching method is different. He created a double-level hatchery in the indoor rack and hatched turtles to be successful. His turtle hatching method is as follows:
First, the structure of the hatchery hatching pool in the room, was rectangular, 2 meters wide inside, 4 meters long. The roof is made of galvanized iron sheet. The roof is about 5 meters away from the ground. The two sides are about 2 meters away from the sky. The middle aisle in the room is about 1 meter. The two sides of the house are each built with a row of two-story hatching pool, built with red brick. to make. Each hatching pond is about 45 centimeters wide, 60 centimeters long, and 30 centimeters deep. It is inclined at 20-30 centimeters and has a drainage hole. Each side can build 4 hatching pools. The first floor is 1 meter away from the ground, and the second floor is about 1.5 meters above the ground. There are 8 hatching pools on one side and 16 hatching pools on both sides. There are two convection windows on both sides of the wall for ventilation.
Second, the method of hatching turtles
1. Before the turtles lay their eggs, the hatchery is first fully sterilized and sprayed with caustic soda or black cyclone liquid to kill ants, cockroaches, viruses and bacteria, creating a good and safe incubation environment.
2. The hatching sand should be sun-dried in the hot sun, and the sand should be dried well.
3. From April each year, it is necessary to pay attention to the location and time of spawning of various turtles. In order to grasp the date of harvesting turtle eggs, collect the turtle eggs two days after the eggs are laid. Be careful when digging turtle eggs. To prevent breakage of turtle eggs, separate eggs and eggs from unfertilized eggs. For example, an egg that is contaminated by a mud belt on a turtle egg surface must be washed first and then dried to remove water from the epidermis.
4. Incubate the fertilized eggs in the hatchery in the hatchery. Place about 10 cm of dried river sand at the bottom of the hatchery, and put the eggs of the same species at the bottom. When the turtle eggs are released, the animals are facing up. Place one by one, put only one layer, and then cover it with 8 cm of sand. The humidity of the sand should be able to form a mass and loose, that is, not wet nor dry.
5. After the eggs are laid, place a bottle of mineral water 6 cm away from the turtle's eggs. Cut the bottom of the flask into two empty bottles. Drill about 20 holes around the bottle for ventilation.
6, daily management: Every week or so, check the turtle's eggs, check to take care, if any eggs to clear. Water in the hatchery to keep the sand moist. About 60-80 days of turtle hatching, the turtle eggs will be automatically broken shell emergence, the small turtle seedlings collected in the basin, do not feed, wait until the turtle umbilical cord off after healing, turtle seedlings can be placed in the water, and then put some Hydra or Tenebrio fed turtle seedlings.
Third, the characteristics of successful hatching
1. He has a soft spot for raising turtles and is also his hobby. In order to raise the turtle well, he specially ordered a Guangdong agriculture and "Southern Rural News", newspaper article on the possession of turtles, he must read every article. He collected all the materials related to turtles in order to learn the length of the people and make up for them.
2. He feeds turtles every day at 9 am and 6-7 pm and feeds them at regular intervals. Turtle feeds on his own to feed on the mealworms as a feed for turtles, plus he buys small shrimps and green feed. Turtles are omnivorous animals. He often observes the living habits of turtles and pays attention to the breeding rules of turtles. Prior to the hatching season, breeding male and female turtles aged four years were paired. In order to increase fertilized eggs, 1:1 or 2:1 was adopted, which was favorable for the fertilization of turtle eggs. For example, 48 snapping eggs were first laid this year, and 48 were fertilized. 4600 small snapping turtles hatched in a rack-type hatchery amounted to 4,600 yuan.
3, he divided the turtle species, the size of the feeding, so that he raised a good growth of turtles, especially Brazilian turtles and snapping turtles grow fast, the annual weight gain 1-2 kg, it is worth promoting the farming species.
4. According to the habits of turtles of different species, he created places suitable for the living needs of turtles. Some turtles are amphibious, some turtles are terrestrial, and they provide hidden places. He has taken such serious care and he has not found any pathological status of the turtle.
5. It has been proved by practice that incubating all kinds of turtle eggs with indoor two-layer hatchery is successful. No matter if the turtles such as Snapping Turtles, Brazilian Turtles or Chinese Tortoises can hatch turtles in the hatching pool, The hatching method is safe and energy-saving. Using a galvanized iron tile can increase the temperature of the hatching pool and accelerate the hatching time of the eggs. This hatchery can also hatch turtle eggs, and more than 20,000 turtles have been hatched this year. In short, this type of hatchery hatching turtle seedlings is feasible, low overall cost, is conducive to turtles to develop large scale aquaculture production and achieve better economic benefits.

Green Plum Wine is specially formulated by soaking the selected green plum produced in the Kuaiji Mountains after ripening, and adding wolfberry and hawthorn extracting solution. Osmanthus used in Osmanthus Wine was picked in Osmanthus forest with a history of more than 900 years.
