The use of a three-dimensional framework for multi-level flat nets for snails and clams can achieve low energy consumption, small space, easy management, and rapid and high-yield production.
First, species selection:
The white snails are generally used as snails, but it is better to use the French hardy snails that are more hardy, so that they can grow and multiply in synchronization with the four seasons.蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓.
Second, breeding methods:
You can use idle homes or plastic greenhouses. Snail adopts a multi-level three-dimensional framework to carry out multi-level plane net culture and adopt box culture. The three-dimensional multi-level framework is 3 meters long, 1.2 meters wide, and 3 meters high. It is equipped with 11 layers of bed frames from top to bottom. Each layer is 20 centimeters apart, and the lowest layer is 60 centimeters from the ground. Each layer is fixed with a nylon mesh tent to form a supporting mesh bed. The meshes of the upper 1st to 2nd layer net beds are more than 1 mesh, so that the spawning snails cannot pass through the meshes, while the medium and young snails can fall from the meshes. The meshes of the 3rd to 4th meshes are 2 meshes, the meshes of the 5th to 6th meshes are 3 meshes, the meshes of the 7th to 8ths meshes are 4 meshes, the 9th to 10ths meshes are The hole is 6 mesh, and the bottommost layer of the net bed hole is 8 mesh. A 30-cm wide and 25-cm high production hatch was made on the side of the uppermost layer of the net bed, and an incubation matrix of about 20 cm thick was placed in the hatchery. The matrix was mixed and fermented with wood chips, straw (cut into 2 cm long) and vegetable garden soil in a ratio of 1:1:1. Apply lime slurry around each bed frame to prevent snails from crawling off the net bed.
The bottom of the three-dimensional frame is surrounded by a wooden box with a height of 30 centimeters, and the bottom of the box is filled with 10 centimeters of vegetable garden soil, and then the decomposed cow dung or pig dung straw fermentation material is added, and 20% of the fermented wood chips are added as a plutonium. The bait. The moisture content of the bait is kept above 60%.
Third, to species breeding:
If the temperature is above 15°C, the species can be farmed. The uppermost layer of the shelf is a kind of spiral layer, which can be inserted into the distant parental species snail at a density of 200 per square meter. You can invest 2.5 kilograms (about 5,000) per square meter. Snails have a wide diet, and vegetables, aquatic plants, crops, leaves, and even leaves of hardwood trees can be used for feeding. The eel's diet is more miscellaneous. Almost all plant residues, corrosive substances, rotten animals, and household waste are its food. When feeding, wash the green material directly on the 1 to 2 layer mesh bed. In this way, the remaining small pieces of the snails will fall into the lower layers of the net bed and become bait for the medium and young snails. The excrement and food waste produced by the snails on each layer of the net bed will fall on the boring machine and become food for crickets. It is estimated that about 5 kg of feces will be excreted per day by 5 kg snails (about 100), plus the food residue of snails, which can be used for eating more than 0.5 kg of clams. When the snails are dropped from the larvae to the snails and distributed on the tiers of net beds, the excrement and food debris of the snails are basically enough for the crickets. In this way, not only the tedious work of feeding and cleaning the excrement is alleviated, but also the utilization of the feed is greatly improved.
Fourth, management points:
In the ecological environment, reasonable regulation and control, snails and cockroaches almost no threat of disease.
1. Temperature: Keep the temperature above 20°C. If the temperature reaches 30°C, take measures to reduce the temperature. If the temperature is lower than 15°C, warm it up.
2. Light: Snails and crickets are hi yin animals and have habits of nocturnal emission. When lighting, pay attention to the amount of light. It is advisable to use a light intensity of 3 watt bulbs per 10 square meters in the darkroom.
3. Humidity: Both snails and crickets prefer wet conditions. The indoor air humidity should be maintained at 60% to 70%. The humidity of the snail incubation matrix should be maintained at 30% to 40%, while the moisture content of the bait should be maintained at 60% to 66%. Snail bait should be soaked and fed.
4. Air: Snails and clams are cultured in high density and produce a lot of harmful gases. Therefore, pay attention to frequent ventilation and maintain sufficient oxygen. At the same time, during the course of life, the cockroaches will continuously discharge the excrement on the surface of the bait. Therefore, the cockroach excrement must be regularly cleaned to facilitate ventilation.
5. Grading and harvesting:
1 Classification of snails: Snails have a habit of eating small foods, so large, medium and small snails of different ages cannot be polycultured. Mesh beds with different meshes are used for breeding, so that the snails are automatically screened and graded, that is, snails of different sizes will shrink under the frightened condition (such as strong light and vibration) and fall down the lower layer. When each level of snail grows to a superior age, manual selection is required. At the same time, the above screw can be harvested.
2. Harvesting: When most of the weight in the bed has reached 400 to 500 milligrams, at this time, the density per square meter has reached 1.5 to 20,000, and most of the weight can be collected.
