What words does the author use to raise silkworms, clearly and concisely introduce the process of ra

1. Four words and macros summarize the process of silkworm rebirth: silking - cocoon formation - pupation - moth.

2. Silkworm (scientific name: bombyx mori) is a lepidopteran insect, the main raw material of silk, which occupies an important position in human economic life and cultural history. Native to China, South China and Taiwan, the shirt is commonly known as silkworm babies or mothers.

3. The English name of silkworm is "silkworm" (meaning "silkworm") because it uses silk to weave cocoons. The cocoon is made from a 300-900 meter long silk weave that collapses violently. Nowadays, China's cocoon silk production and export volume account for more than 70% of the world's total, and has become a major cocoon silk country that can dominate the world's cocoon silk trend.

1. Treat the mulberry leaves: put a pound of high-quality water (it must be good water, which can be eaten by people), and then add 5 ml of fermentation broth and spray it on ten catties of mulberry leaves. In this way, the silkworm baby will grow white and fat after eating.

2. Take measures to prevent heatstroke: every day at noon and afternoon, use water to add about 5 ml of fermentation broth and spray it on the surface of the silkworm baby. In summer, the weather will be hotter, and silkworm babies will die of heat stroke, so be sure to take heatstroke prevention measures.

3. Mulberry leaf preservation method: If the mulberry leaves bought back are not all eaten on the same day, they will become dry after a few days, which is very difficult for the silkworm baby to eat and digest, which will affect the growth rate of the silkworm baby. Therefore, it is necessary to spray some water on the surface of the mulberry leaves, then put it on the cool ground and cover it with a plastic bag, so as to keep the moisture from losing too quickly.

4. Prevention of air poisoning in pesticide machines: Mulberry leaves will be sprayed with pesticides, and they should be confirmed to be non-toxic before feeding to silkworms. In summer, windows should be opened frequently for ventilation, and cooling measures should be installed indoors.

5. Sick and disabled should be cleaned up in time: silkworms that die due to illness and other reasons must be cleaned up in time, and do not throw them to livestock at home to eat to prevent the spread of pathogens.

6. Avoid other species from infringing on silkworms: The house where silkworms are raised should be kept clean, and there should be no other insects, so as not to harm the growth of silkworms. It is necessary to clean the room normally, and do not pile up items and some cereals that are prone to insects in the house.

1. Silkworm room environment:

The silkworm room can choose a greenhouse or a cement house, the ground must be flat, clean and tidy, and there must be diagonal windows before and after, and it is best to open the corner windows if conditions permit. Install windows, doors and mesh to prevent flies.

or other insects fly into the silkworm room, and the corner window should also be equipped with barbed wire to prevent rats from penetrating. If you want to raise 1 silkworm, you need about 30 square meters of silkworm breeding area and 10 square meters of dedicated mulberry room.

2. Silkworm tools and medicines:

If you raise 1 silkworm, the main silkworm tools and medicines are: 15-20 silkworm dustpans with a width of rice; 4 leaf baskets, about 20 square meters of medicinal film; 2-3 pairs of slippers, placed in the silkworm room and mulberry leaf room respectively; several red bricks; 2 sterilization barrels and 1 sprayer for the silkworm room; Lime about 60 kg.

3. Mulberry leaves: for silkworm babies.

Provide fresh mulberry leaves, no need to buy or pick too many mulberry leaves at once, only need to take one amount. If you want to provide fresh mulberry leaves for silkworm babies in time, you can choose to plant your own mulberry trees.

It not only ensures the freshness of mulberry leaves, but also provides mulberry leaves for silkworm babies in time.

4. Disinfection: The first phase of disinfection should be completed within one week before the silkworm is harvested. That is, it is necessary to thoroughly clean the silkworm room, mulberry leaf room and the surrounding environment, and place the silkworm tools in the sun, and then disinfect the silkworm room and silkworm tools with a special disinfectant.

1. Remove sand before sleeping. This is to avoid excessive accumulation of silkworm manure, which is very easy to breed and spread, and then invade the silkworm body during the sleeping period.

2. Silkworms do not eat or move during the sleep period of Fan Yu, and mainly rely on the nutrients absorbed by eating mulberry before sleep to maintain life activities. So be sure to eat and sleep. If you stop giving mulberry too early, it will cause starvation, and the hungry silkworm is weak, has poor resistance, and is prone to disease.

3. Silkworms have weak resistance to various external disturbances during the sleeping period, so we must pay attention to the protection during sleep. When 95% of the silkworms are asleep, they should be sprinkled with fresh lime powder and silkworm medicine to prevent disease No. 1" to prevent the invasion of germs. If a small number of silkworms do not eat mulberry and do not sleep, it is because it has not found a place to sleep.

At this time, put some mulberry leaves, and sleep in batches.

4. Silkworms are ectotherms, and the adaptation range is 20 30. Spring silkworms often encounter low temperature and humid climates during the number holding period, and the focus is on supplementing temperature and removing humidity. The summer silkworm period is high temperature and humidity, and the focus is to cool down and drain moisture, keep the air circulation in the silkworm room, and clear the stuffiness.
