Temperature: Silkworm is a kind of creature that is very afraid of cold, so April-May is usually the best time to raise silkworm every year, when the temperature is basically around 20-25℃.
Mulberry leaves: Note that mulberry leaves are best fresh. Mulberry leaves left at home for the night can also be used to feed silkworms.
Health: Clean it every day. Although silkworm excrement has certain medicinal value, it will produce bacteria in the feeding room and cause some diseases.
Disease prevention: Silkworm is sick, so it must be isolated.
First, what should I pay attention to when raising silkworms?
1, temperature
(1) Silkworm is a kind of creature that is afraid of cold, so most people will hear about spring silkworm, so we must pay attention to the feeding temperature when raising silkworm.
(2) generally choose to raise silkworms from April to May every year, when the temperature is almost 20-25? C, there is no need to adjust the temperature of the culture room.
2. Mulberry leaves
(1) You must pay attention to the freshness of mulberry leaves when raising silkworms. Mulberry leaves kept at home for one night can also be used to feed silkworms, but they will not be fresh if they are kept for too long.
(2) Secondly, it should be noted that the mulberry leaves must be cleaned without dust, and at the same time, do not feed the silkworms with dew or mulberry leaves that have not been dried after cleaning, because the silkworms will die of diarrhea after eating this mulberry leaf.
(3) Mulberry leaves sprayed with pesticides cannot be picked and fed to silkworms, because silkworms are particularly sensitive to toxins.
3. Hygiene
(1) The living habits of silkworms are similar to those of pigs, and they eat and sleep, but silkworms are much more fragile than pigs, so the sanitary environment of the feeding room is also very demanding.
(2) Many farmers usually clean it every few days when breeding, which is actually wrong. They must clean every day.
(3) Although silkworm excrement has certain medicinal value, it will produce bacteria and cause some diseases when piled up in the breeding room.
(4) The skin taken off by silkworms and the leftover mulberry leaves must be cleaned up in time, especially the food residues.
Step 4 manage
(1) The management of sericulture is mainly manifested in feeding, living and cocoon formation. When feeding, be careful not to feed all the mulberry leaves at once, at least twice in the morning and evening.
(2) Secondly, we must pay attention to daily management, that is, we can't smoke incense, put mosquito-repellent incense, perfume and other strong-smelling things in the breeding room, so that silkworms will die.
(3) In the cocoon-forming period, a cocoon-forming place should be prepared for silkworms, so that they will not be so laborious when cocoon-forming. Without help, they are likely to become pupae before cocoon formation.
5. Disease prevention
(1) Silkworms have many minor illnesses. These diseases are basically based on prevention. Secondly, when the silkworm is sick, it must be isolated and disinfected with special chemicals.
(2) Sick silkworms must not be littered, because they are highly contagious, and animals such as mites, mice and chickens cannot be put into the feeding room, otherwise the loss will be great.
Second, the method of sericulture
1, preparation work
Be sure to prepare a clean and odorless carton before raising silkworms, and then tie some small holes in the carton to facilitate ventilation.
Step 2 hatch
Silkworm eggs are put in cartons at a temperature of 2 1-29? C, the incubation time is generally around 1 1 day.
Step 3 feed
(1) When the silkworm baby is about to hatch, you can put a proper amount of fresh mulberry leaves in the carton for the silkworm baby to eat.
(2) When the silkworm is in the young silkworm stage, it can choose to feed fresh mulberry leaves, and when it is in the big silkworm stage, it can feed ordinary mulberry leaves.
(3) Mulberry leaves must be carefully checked before feeding, and the diseased leaves, moldy leaves and insect leaves should be picked out. At the same time, there should be no water on the mulberry leaves, otherwise the silkworms will easily have diarrhea after eating.
Step 4: Clean
(1) Be sure to take out the old mulberry leaves in the carton regularly, replace them with fresh ones, and clean up all the silkworm excrement in the carton.
(2) When changing mulberry leaves, be sure to clean the feces with a brush. You can gently sweep the silkworm from the old mulberry leaves to the new mulberry leaves, then clean the silkworm droppings and the old mulberry leaves in the carton, and finally put the new mulberry leaves in the carton.
(3) If there are dead silkworms in the carton, they must be cleaned up in time to avoid infecting other silkworms.
5. Suitable environment
(1) Temperature: The suitable temperature for the first instar silkworm is 27-28? C the suitable temperature for the second instar silkworm is 26-27? C the suitable temperature for the third instar silkworm is 25-26? C the suitable temperature for the fourth instar silkworm is 24-25? C the suitable temperature for the fifth instar silkworm is 23-24? C.
(2) Humidity: The suitable humidity for the first instar silkworm is 80-85%, the second instar silkworm is 85-90%, the third instar silkworm is 75-80%, the fourth instar silkworm is 70-75%, and the fifth instar silkworm is 65-70%.
(3) Be sure to avoid direct sunlight on cartons.
