Life habit of white jade snail
1 likes warm habits: the temperature required for its fastest growth is between 25 and 30 degrees. 2.2 The habit of loving humidity
2. The air humidity shall not be lower than 50%, and the soil humidity shall not be lower than 20%, but the humidity is too high. If the atmospheric humidity is saturated, that is, 100%, and the humidity of the feeding box is greater than 85%, all kinds of pathogenic bacteria will cause food in the box and make it sick.
3 Zou obvious dark habits:
Snails are afraid of strong light and have obvious dark habits. I like living in the dark. Belongs to animals that lie down during the day and come out at night. If you are raised in the wild or open air, you can only see the food in the range of 4-5 mm under strong light, so even in the breeding room with windows, you can't live in the daytime, and all activities are carried out at night. Darkness is by no means darkness. If the snail is kept in complete darkness, it is not good for its growth and reproduction, because weak light can not only provide it with food, but also need some light energy to stimulate its gonad development. Without light, he won't develop, and he won't mate or lay eggs for a long time, so snails should have some scattered light when they are raised. 2.4, omnivorous and partial eclipse habits
Snails have a wide range of food habits, so they won't eat bad food if they have a choice. Such as animal carcasses or such carcasses and lignin. Because snails eating these foods will not be of great benefit to their growth and development, and sometimes it will be harmful. But I have to eat it in order to survive.
The so-called partial eclipse means that you especially like to eat delicious food, and snails are very partial. The following phenomena are often found: for example, 1, a snail farmer often feeds Chinese cabbage leaves as feed, feeding five kilograms a day, and picking out the remaining half on the third day, that is, the total food intake is less than 2.5 kilograms. When you feed another sweet potato (cucumber), you get 7.5 kilograms each time, and you eat it up without even the skin left. But after the third day, after feeding the locust leaves, it couldn't help being hungry, but it still ate. It also has good animals that don't eat bad.
Breeding method of white jade snail
White jade snails are hermaphroditic and cross. As long as the temperature and humidity are well controlled, artificial breeding can reproduce all year round. The young snails reached sexual maturity at the age of 6 months, and laid eggs 10- 15 days after mating and fertilization. Most eggs are laid in caves, on vegetable leaves or on block sponges. The egg is oval, with a milky white calcareous shell and the size of mung bean. Each spawning 100-200, with an annual output of 3-8 nests. After the eggs are laid, they can be collected and hatched in pots or wooden boxes, and the mucus and feces on the eggs do not need to be scrubbed. Put the feeding soil under the eggs, cover the soil with wet cotton cloth or sponge, evenly arrange the eggs on the eggs, cover the eggs with wet cloth, then seal the pot mouth with plastic film, and hatch the young snails in 8- 15 days. When incubating, the temperature must be kept at 20-30℃ and the humidity must be kept at 80-90%. Iv. Breeding technology of white jade snail 4. 1 feeding mode
1) Open-air culture: Farmland can be used, the soil can be thinned, broadleaf trees can be planted around it for shade, and fences can be used around it to prevent snails from escaping. You can also use the roof of a flat-roof house, pad with loose soil above 10 cm, plant a few grapes around it, put up a shelf to shade the sun, and block it with a net around it. The advantages of this farming method are fresh air, good humidity, fast growth of snails and low incidence. Pay attention to sprinkling water in time during drought to keep the soil moist. Drainage should be done in time when it rains. Pay attention to the dangers of natural enemies and wild animals, especially cats and dogs at home.
2) Indoor culture:
Plane culture and stereoscopic culture. Planar cultivation is to build a square of 2 -3 square meters with bricks indoors, with a height of about 25 cm, and loosen the soil with padding above 10 cm. Three-dimensional culture should first make wooden boxes and shelves. Fill the box with loose soil above 10 cm and put it on the shelf layer by layer. The height of the box is about 25 cm, and the length depends on the need.
Note: Open the doors and windows for ventilation every day. Pay attention to adjust the temperature and soil humidity to keep the soil clean and indoor sanitation. Boxes and ponds should be covered with breathable nets to prevent snails from escaping.
3) Plastic greenhouse cultivation:
Choose an open space 30 meters long and 6 meters wide, and plow it first. Surrounded by a 30-cm-high fence with an arched shed, the door opens back and forth. The ploughed soil in the shed can be cultivated after it is leveled and fine. The advantage of this feeding method is that it is convenient to adjust the temperature and prevent natural enemies. However, it should be noted that in high temperature season, sunshade equipment should be added to keep soil moist and air convection so as to discharge carbon dioxide in time. 4.2.4.2.1preparation of compound vegetable garden soil
30% of unpolluted pastoral soil, 30% of sandy soil, 20% of yellow sand, 15% of cinder ash and 5% of stone powder are mixed and crushed, disinfected and sterilized by sun exposure for 3-5 days, sieved, and then water is added to make the humidity around 40%, that is, kneaded into a ball, and dispersed by blowing. The soil thickness in the basin is: adult snail 10 cm, adult snail 7 cm, young snail 3 cm, feeding soil 1-2 months. 4.2.2 Sponge substitution method
Lay 1 5cm sponge on the bottom of pools, boxes, etc. , and keep 4 times its own weight of water. Clean up the leftover food every day, and clean up the feces every 3 days 1 time.
4) Feeding methods
1 month-old young snails should be fed with fresh and tender leaves, and the concentrated feed should be scalded with boiling water and then stuck to the leaves, and fed once a day 1 time. The optimum temperature should be controlled at 25-30℃, and the temperature difference between day and night should not be large. Don't spray young snails directly when spraying water. In addition to green feed, the growing snails should be fed more concentrated feed and added with trace elements and additives. The daily feeding amount is 7%- 10% of the snail's weight. Feed should be put into a food rack or basin to clean up the residue. The stocking density is from dense to sparse with the increase of individuals, with 400-200 animals per square meter. 60? 30? A 25 cm feeding box can feed 100 pigs. After 5-6 months, when the shell is 4 cm high and weighs more than 40 grams, it can be harvested.
Overwintering management of white jade snail culture
When the temperature drops below 5 degrees Celsius in winter, snails will die one after another. Therefore, artificial breeding snails must be kept warm to ensure safe winter.
Temperature control The temperature of the wintering room must be controlled at 20-30 degrees Celsius day and night. If the temperature drops below 15℃, or rises and falls, it will have adverse effects on Oncomelania hupensis. Indoor heating, generally speaking, the upper temperature is high, the lower temperature is low, it is hot near the stove, and the stove is cold, with a temperature difference of 3-5 degrees Celsius. Therefore, it is necessary to change the position up, down, left and right regularly. The incubation temperature of snail eggs is about 26 degrees Celsius. The incubator can be placed on the upper floor or near the stove, and adult snails can be placed on the middle floor, which is convenient for mating and spawning and accelerates reproduction. 1-4-month-old snails can be raised in the lower layer.
Humidity control In winter, the air and feeding soil in the wintering room are easy to dry. Sprinkle water 1 time on the ground every day, and at least sprinkle warm water 1 time equivalent to room temperature on the feeding soil every day to maintain humidity. You can also improve the air humidity by watering the sawdust stove.
The overwintering room with air conditioning has small area and high stocking density, which is easy to cause indoor air pollution and is extremely unfavorable to the growth and reproduction of snails. So pay attention to frequent ventilation.
Feeding can be done once a day 1 time, or every other day, and the feeding amount should be flexibly controlled according to the temperature and snail situation.
