Second, the indoor culture method Indoor culture method can be divided into two kinds of plane culture and three-dimensional culture. 1 Plane culture: In the room, bricks with a height of about 25 cm and a size of 2 to 3 square meters are placed on the grid. 2 Three-dimensional breeding: First, do a wooden box (about 25 cm in height, depending on the length and needs) and the rack. Place 10 centimeters of loose soil in the box, and put the box on the shelf. This farming method is simple and easy to implement, with less investment and safety. Care should be taken to open doors and windows every day for ventilation; adjust the temperature and soil moisture; keep the soil clean and the indoor hygiene; cover the top with a breathable net to prevent snails from fleeing.
Third, the plastic greenhouse culture method choose 30 meters long, 6 meters wide open space, first plough through it again, around the wall of 30 cm high, build a plastic greenhouse, open the door before and after, the shed in the ploughing soil leveling fine Farming. The advantages of the plastic greenhouse culture method are that it is easy to adjust the temperature and prevent natural enemies.

Three methods for snail farming
First, open-air cultivation method Open-air culture method can use farmland for aquaculture. After the ploughing, the soil was fined, the broad-leaved trees were shaded around the field, and they were stopped by a net to prevent the snails from fleeing. It is also possible to use the roof of a flat-roofed house for breeding. In the roof pad, loose soil is more than 10 cm thick. Several kinds of grapes are planted around and covered with shading. The surrounding area is also blocked by a net. The benefits of open-air farming are that the air is fresh, the humidity is good, the snail grows fast and the disease is light. It should be noted that water should be sprayed in time for drought to keep the soil moist; when there is a lot of rain, it must be drained in time; and to prevent natural enemies and livestock and poultry from infringing, it is even more important for families to have large cats.
