1. How do you artificially incubate the eggs laid by white jade snails? How do you breed the hatched snails?

After the female snail lays eggs, use a spoon to collect the eggs in time and put them in an incubator. Put one centimeter of breeding soil on the bottom of the box, and then put the snail eggs on it. Try to keep it as it is. Cover the eggs with about one centimeter of breeding soil and spray water (mist) twice a day. In this way, they will be hatched in about 12 days at a temperature of about 25 degrees. Then, pick out the young snails and put them in the breeding box, feed them with vegetable leaves and sprinkle water. After 20 days or when they are a little older, they can be put into the wild or put into the breeding box for normal breeding. After about a month, feed them with a small amount of concentrated feed. 1. About temperature

The white jade snail is a cold-blooded lower animal. It does not have the function of regulating temperature by itself. Therefore, in the whole process of breeding white jade snails, giving it a temperature suitable for its growth is the key to the success of white jade snail breeding. The best growth temperature of white jade snails is 22 to 30 degrees. Within 18 degrees, it will gradually stop eating. Within 15 degrees, some snails will enter a semi-hibernation state and may cause frostbite. In summer, a small number of open-air snails above 35 degrees will be in a summer hibernation state. At this time, they should be sprinkled with water to increase humidity and lower the temperature. Therefore, where conditions permit, shade nets should be used to block the sun to avoid exposure to the sun. It must not be exposed directly to the sun, otherwise, it is easy for snails to dehydrate and shrink due to high temperature exposure. Commonly used insulation methods include the following: (1) Floor duct insulation method: chisel a 25 cm square hole at the base of the wall, build a wood stove, and then build two brick floor ducts 30 cm high and 24 cm wide from the hole, with the same length as the horizontal direction of the breeding room, and hide them under the ground where the breeding rack is placed. At the other end of the wall, the two floor ducts meet to form an outlet, and exhaust gas is discharged from the chimney. As long as the firewood is not extinguished day and night, the indoor temperature can be maintained between 25 and 30 degrees. At the faucet near the stove, more water should be sprayed to adjust the indoor air temperature and humidity and reduce the high temperature at the floor duct outlet. (2) Plastic greenhouse insulation method: This method can be large or small (it can also use idle or economically inefficient vegetable greenhouses). In a leeward and sunny place, use double transparent plastic film to build a greenhouse, and use ground temperature and sunlight to assist in insulation. This method is suitable for the south. In winter, when using greenhouse insulation to cultivate snails in three-dimensional form, auxiliary heating is also required. The heating methods are flexible and diverse, and both fixed and mobile simple insulation facilities can be used. (3) Tunnel insulation method: On the eve of wintering, snails are transferred to basements, air-raid shelters, caves and other air defense facilities for breeding, which can effectively save energy. You can also choose a leeward and sunny place outdoors or use terrain and solar energy to rebuild a tunnel-type insulation room. This method of using ground temperature also requires other insulation methods. (4) Wood chip and coal stove insulation method: The exhaust pipes of these two fuel stoves are made of iron sheets, with a diameter of 20-25 cm. The end of the exhaust pipe of the three-core coal stove is 6-7 cm, and the end of the exhaust pipe of the single-core stove is 2.5 cm. The exhaust pipe bends along the indoor passage and extends to the outside to discharge exhaust gas, which is conducive to gathering heat and purifying indoor air. (5) Heating insulation method: This method uses heating pipes, boiler exhaust gas or cooling water discharged from some factories to enter the breeding room as a heat source for snails to overwinter. If the gas and water are cut off, other methods should be used immediately to heat. (6) Power insulation method: It mainly uses light bulbs and electrical equipment. The light bulbs can be placed between the boxes, 30 cm from the ground. The power of the light bulbs should not exceed 100W. You can install more to facilitate balanced insulation. (Note! The cost of using electricity for insulation is too high. Once the power is cut off at night, it will cause losses). The indoor area of ​​the insulation room is generally a single room of 20 square meters. Various three-dimensional box containers or wooden boxes are made indoors, and 4-5 cm of sand or garden soil is placed inside the box for snails to live and live. Generally, a 20-square-meter house can overwinter about 10,000 finished white jade snails. The entire insulation period is preferably from mid-November to mid-April of the following year, which takes 5 months. Note: The exhaust gas generated by the heat source and insulation equipment is toxic. Pay attention to personal safety during the winter insulation period!

2. About humidity

White jade snails belong to the category of "terrestrial shellfish". Although they do not live in water like field snails, they also need higher environmental humidity and soil humidity. During the entire breeding process, they should be sprayed with water two to three times a day (in the form of mist), and the mother snail box should be kept ventilated. The soil should be kept moist. The general standard is "knead it into a ball, and sprinkle it into sand". Especially during the high temperature in summer, it is important to spray water in time. Insufficient humidity can easily cause summer hibernation or even shrinkage of the shell and stop growing. White jade snails are very sensitive to humidity, so! It is very important to control the humidity. In short! Breeding white jade snails should follow the "three highs" breeding mode (high temperature, high humidity, and high calcium).

3. About Food

White jade snails like to eat leaves of green plants and juicy green leaves, fruits, vines and other plants (add a small amount of concentrated feed; chicken, pig feed, rice, bean cake, rice bran, etc.), and spray the feed with water. As the white jade snail grows, it needs to add an appropriate amount of calcium to supplement it, but the white jade snail is sensitive to alkali, so pay attention to the use of calcium food when supplementing calcium. In the concentrated feed, you can add an appropriate amount of bone meal and other ingredients. At the same time, in the soil of the breeding soil, you can add old slaked lime to make it have a lot of calcium supplemented, especially for the species of snails. This is particularly important. When the winter is properly insulated, the snail's appetite does not decrease, and the quality of the food is appropriately improved, so that it can grow normally during the insulation period. At the same time, it is necessary to take care of the snail's partiality and omnivory. Do not feed a single feed for a long time, and replace a green feed that the snail likes to eat after a period of time. Mix multiple feeds. Insist on removing residual feces every other day and cleaning the ground. (Depending on the situation, you can feed them once every other day, with about one or two ounces of concentrated feed per hundred snails each time).

2. How to hatch snail eggs?

Young snails reach sexual maturity at 6 months old. They lay eggs 10 to 15 days after mating and fertilization. Most of the eggs are laid in caves. When hatching on leaves, the temperature must be maintained at 20 to 30 degrees Celsius and the humidity must be 80% to 90%.

3. How to hatch snail eggs

Snail hatching must meet three important conditions, namely, suitable temperature, suitable humidity and insect-free and sterile environment. The so-called suitable temperature is 18℃-28℃. If the temperature is higher, the mortality rate of small snails is high; if the temperature is slightly lower, the hatching time is long; if the temperature is too low, they cannot hatch. The humidity of water or soil should be suitable, and they will form a ball when grasped by hand and fall apart when they fall to the ground. If the humidity is high, the eggs will rot, and if the humidity is low, the eggs will dehydrate and die. In order to make the sand or soil used for hatching free of insects, bacteria and other microorganisms, high temperature is generally required. Under high temperature, insects, eggs, bacteria and other microorganisms can be eliminated. The author has repeatedly tested and explored a hatching method that is both simple and has a very high hatching rate. The specific method is as follows: put fine sand (sand sieved with a fine sieve or a coarse sieve) or sandy soil into a pot and add high temperature (above 200℃), and use a shovel or a small shovel to stir it continuously to make the heating uniform. Take it out after heating and let it cool for use. The storage time of heated fine sand is longer in winter and shorter in summer. Take a portion of the cooled fine sand and place it in a porcelain or plastic basin with a thickness of about 3 cm. Pour in a little boiling water (hot or cold) and stir evenly (note: do not pour in a lot of boiling water at once). If you see dry sand, add some more water and stir. The sand should be wet but without water droplets (i.e., it can be clumps when grasped by hand and fall apart when dropped). Smooth the sand surface in the basin. If there are few eggs, use a spoon to make a groove 1 to 2 cm wide and 1 to 2 cm deep, put the eggs in the groove, and cover the eggs with a thin layer of sand on the edge of the groove, so that the eggs are not exposed. After placing the eggs, cover the basin tightly with glass. After more than ten days, you can see many small snails running on the sand. At this time, you can take out the snails and the sand in the middle together. Sprinkle it evenly on the breeding soil, and then put a layer of vegetable leaves on it. Do not dig out the small snails in advance. The small snails will be stronger after eating the egg shells after hatching. The sand left in the basin after digging out the snails can still be used after heating.
