What's the use of sericulture? The role of sericulture lies in silk, which is one of the main textile raw materials. China was the first country to use silk.
In ancient history, there are legends of Fuxi's "silkworm rearing" and Leizu's "teaching people to raise silkworms", that is, the earliest people who raised silkworms.
Archaeology in the Neolithic Age shows that before 2750 BC, the ancestors of Qianshanyang in Xing Wu, Zhejiang Province had woven silk sheets, ribbons and silk threads with silk.
In the 3rd century BC/KLOC-0, names such as mulberry, silkworm, silk and silk were found in Oracle Bone Inscriptions.
Silk, together with hemp, ramie and later cotton, is the main clothing raw material for China people, and sericulture has become an important part of China's agricultural structure.
Matters needing attention in sericulture:
1, the ant silkworm is very small and its body is dark. When feeding mulberry leaves, it is best to choose soft mulberry leaves, and at the same time, it is best to cut them short with scissors to make them convenient for ants to eat.
2. When the ant silkworm grows up a little, the mulberry leaves don't need to be cut, mainly young leaves, which are convenient for silkworm babies to eat.
They are now slightly white.
Because mulberry leaves are tender and dry faster, we should pay attention to adding leaves in time.
3, the silkworm baby eats fiercely, grows fast, and the appetite is easy to molt. Silkworm babies don't move much, and then they start molting. Don't think it is morbid.
4. After molting for the fourth time, the silkworm baby's body is already relatively transparent and ready to enter the spinning state.
In about five days, you can harvest cocoons.

What is the function of silkworms? What are the uses of silkworms? Silk can be used as silk quilt: silk quilt has the characteristics of moth-proofing, antibacterial, antiallergic and skin-friendly.
Silkworm dung can be used as a pillow: silkworm dung is warm and sweet, and has the functions of eliminating dampness and expelling wind, strengthening brain and improving intelligence, calming the nerves and lowering blood pressure, and regulating sleep.
Silkworm excrement can also be used as medicine to dispel wind and remove dampness.
The skin shed by silkworms can be used as medicine.
Silkworm pupae are edible, and the content of protein is extremely high.
Silkworms are divided into two categories; A kind of silkworm, namely silkworm.
Mainly feed on mulberry leaves.
The other is called mountain silkworm, namely tussah, which feeds on oak leaves.
Silkworm life goes through four stages: egg, larva, pupa and moth.
It is the larva of silkworm moth and the main raw material of silk products, and occupies an important position in human economic life and cultural history.
Originated in the south of China, ancient documents in China recorded that Emperor Xuanyuan began to raise silkworms. The most famous in Jiangnan is Lei Zu, the wife of the Yellow Emperor.
The staple food of silkworm is mulberry leaves, and a small amount of castor leaves can also be added.
Cocoon is made of a continuous silk with a length of about 300 ~ 900 meters (1000 ~ 3000 feet).
Adults and pupae of silkworm can be eaten and have dietotherapy effect.
Silkworm moths reproduce after laying eggs and mating, and die after laying eggs.
Because of its long history and important economic significance, sericulture has become an important research object of modern science.
What are the advantages of sericulture? There are many advantages to sericulture. Silkworm can be used as medicine: it is mainly used for children to cry at night, except for three worms and darkness, which makes people feel good.
It can be used for treating male vulva pruritus, female collapse, redness and whitish, and postpartum pain.
Grinding to the end; Sealing furuncle to reduce swelling and uprooting it are extremely effective.
Silkworm pupa can be fried and eaten, and its main function is to cure wind and fatigue.
Grinding into powder for drinking, treating infantile malnutrition, reducing fever of long muscles and expelling ascaris.
Drink this soup to quench your thirst.
Silkworm cocoons can also be used as medicine: efficacy: burning ash and shochu, curing carbuncle swelling and headless, and breaking the next day.
It also treats scabies, bleeding, bloody stranguria and blood collapse.
Boil juice to drink, quench thirst and nausea, remove roundworms and silkworm chrysalis.
Efficacy and indications of cocoon marinade: pupa juice in cocoon.
Indications: All insects enter the meat.
Bathe children with soup, get rid of scabies and kill insects.
Cocoons made from silkworms can be spun into silk fabrics.

[Edit this paragraph] Edible function
Alias of raw materials: white-faced waterfowl, white-backed silk, white-backed silk, satin rattan, silver-backed rattan, silk, stiff silkworm, Tian Chong and white-backed silkworm.
Classification of raw materials: dual-purpose food for medicine and food
Introduction of raw materials
Beauveria bassiana is a whole worm, and its larvae died after being infected with Beauveria bassiana.
Silkworms used to die of natural causes. Artificial inoculation and culture have been carried out in recent years. After inoculation, silkworms fell ill and died one after another. Pick it out in time, spread it out separately, keep it at the same temperature, and after it becomes stiff and white, put it in a ventilated place to dry or dry it in weak light.
Beauveria bassiana is cylindrical, curved and shriveled, with a length of 2-5 cm and a diameter of 0.5-0.7 cm.
The surface is grayish yellow, covered with white powdery, frosty aerial hyphae and conidia.
The head is round, with 8 pairs of feet and obvious body joints. The tail is slightly forked, and the middle is bright brown or bright black. Commonly known as "rubber mouth mirror", there are four silk gland rings inside, which are bright rings, slightly fishy and slightly salty.
Nutritional analysis
The white powder on the body surface of Bombyx Batryticatus contains ammonium oxalate.
The culture of Beauveria bassiana can synthesize a lot of oxalic acid, pyridine-2,6-dicarboxylic acid and a lot of fat.
Fatty acids in fat are mainly palmitic acid, oleic acid and linoleic acid, and a small amount of stearic acid, palmitoleic acid and α -linolenic acid.
Beauveria bassiana can secrete at least three kinds of hydrolases, namely lipase, protease and chitinase, which can promote the penetration of infected larvae epidermis.
Glutamic acid, aspartic acid, ammonium oxalate, ammonium citrate and ammonium tartrate can be used as nitrogen sources, but inorganic nitrogen compounds cannot be effectively utilized.
Beauveria bassiana also contains Beauveria bassiana yellow pigment, which accumulates rapidly when the nitrogen source is exhausted in culture. Fibrinolytic protease can also be synthesized.
Beauveria bassiana not only infects silkworm, but also invades corn borer and wax borer larvae. High molecular weight insect toxin and cyclic peptide insect toxin Beauveria bassiana were isolated from it.
Beauveria bassiana also contains steroid 1 1a monohydroxylase system, which is used to synthesize corticosteroids.

Silkworm died of infection with germs, stiff and covered with white powder, hence the name Bombyx Batryticatus.
Worm is the word "silkworm" in two.
The efficacy and function of silk Silk is a natural fiber, which is a continuous long fiber solidified by silk liquid secreted by adult silkworms when they cocoon.
One of the earliest animal fibers used by humans.
Let me introduce the efficacy and function of silk to you, hoping to help you.
The efficacy and function of silk
1. Silk fibroin and sericin are components of spun silk in the medical field. After being treated with concentrated sulfuric acid, the same substance as heparin can be obtained, which has anticoagulant activity and delays blood coagulation time, and can be used to develop blood testing equipment or antithrombotic materials.
By changing some processing conditions in the same way, spun silk rich in water absorption and water retention can be processed into advanced water-based materials or other physiological health care products.
In addition, the spun silk is chemically synthesized by polymer, so that calcium or phosphorus can be condensed with the spun silk, and an "orthopedic material" for orthopedic treatment can be developed.
Similarly, after chemical treatment, artificial muscles or artificial ligaments can also be developed.
Silk fibroin films made of spun silk can also be made into wound protection films for treating burns or other skin injuries.
2. The silk powder processed into particles in the industrial field can be used as an additive for cosmetics or health food, and can also be made into silk paper containing silk powder or food fresh-keeping packaging materials and antibacterial silk materials.
Silk fibroin film is not only used to process contact lenses, but also can be used to mix silk powder as fine as 0.3μm with resin to develop a new product called silk leather.
High-grade coatings made by adding silk powder into some coatings can be used to spray furniture supplies, increase the elegant appearance and good touch of utensils, and are widely used in various indoor decorations.
3. Natural silk fabric mask, leading the new beauty trend.
The structure of natural silk is very similar to human skin, so it has the reputation of "second skin" of human body.
Silk beauty has a long history in China. As early as the Ming Dynasty in China, silk was used by court ladies for daily beauty and health preservation because of its important medicinal value.
According to Compendium of Materia Medica, silk protein powder can eliminate skin dark spots and treat suppurative dermatitis.
Modern medical experiments further prove that the protein content of silk is much higher than that of pearl, in which the nitrogen content is 37 times that of pearl, and the main amino acid content is as high as 10 times.
These amino acids can be directly absorbed and adsorbed by human hair and skin.
That is, it is easier to penetrate into the outer layer of human epidermis and accelerate the metabolism of skin.
Chemical constituents of silk
The chemical composition of silkworm cocoons raised by mulberry leaves is: moisture 1.40%, ash 1. 14%, protein 97.34%, ether soluble extract 0.26% and fiber 0.39%.
Cocoons are mainly made of fibrous protein FIROIN wrapped with another sericin from protein, and also contain a small amount of oil, pigment and inorganic substances.
In raw silk, silk fibroin accounts for about 70% and sericin accounts for about 22%.
Silk fibroin is a kind of keratin, and its amino acids are glycine and alanine, which account for about 80% of the total nitrogen.
105g fibroin contains amino acids in the following order (the number after the substance is the number of moles): glycine 578, alanine 38 1, valine 29, leucine 7, isoleucine 9, serine 157, threonine 12, tyrosine 67, phenylalanine 8 and proline.
Sericin is also keratin, and its amino acids are generally similar to silk fibroin, but glycine, alanine and tyrosine are slightly different. Serine, glutamic acid and aspartic acid are more.
Cocoon also contains 50mg% free hydroxy acid (calculated by glycine).
Cocoon contains oily waxy substances, which are composed of primary alcohols (C28-C32), solid fatty acids (C26-C32), paraffin wax (C25-C3 1) and liquid fatty acids.
It also contains sitosterol (glucoside) and lupeol.
Identification method of silk
Check the appearance
High-quality silk is milky white, slightly yellow, with soft surface luster, no blackening, no astringency and long silk quality. After the surface silk is pulled open, there is no flocculent broken silk inside.
Combustion discrimination
After burning, it smells of burnt feathers, because it contains protein, which turns into powder with the color of wildfire after burning. When burning, it gives off the smell of burnt hair, and there is no fire.
color reaction
Concentrated nitric acid turns yellow
touch control
High-quality silk feels soft, greasy, elastic and free of lumps, while inferior silk feels rough, inflexible and wet.
fibre strength
The better the strength and elongation of silk, the better the quality. After stretching, the longer the silk quilt, the better the quality.
Selection method of silk
First of all, the so-called silk usually refers to the mulberry quilt, which is a domestic silkworm egg with mulberry leaves as its staple food. The silk spit out by silkworms is yellowish white, delicate and smooth, and the quilt made of this silk is soft and close to the skin.
The bulkiness, warmth retention and air permeability of mulberry silk quilt are better than those of tussah silk quilt, and its service life is longer than that of tussah silk quilt. The service life of a bed of mulberry silk quilt is about 10 to 15 years, while tussah silk quilt can only be used for two to three years.
When choosing, you usually follow seven steps.
At first glance, many manufacturers' silk quilts are marked with 100% silk, which is problematic because both mulberry silk quilts and tussah silk quilts can be called silk quilts.
Second inspection: high-quality silk should be milky white, slightly yellow, with soft surface luster, no blackening, no astringency and no flocculent broken silk inside.
Three-pull: pull a small amount of silk from the sample seal. If it is easy to pull, it is probably fake.
Four burns: burn with a lighter to see if there is burnt feather smell.
Five kneading: first knead the silk at the sample mouth by hand, and then knead other places. If it feels different, it proves that other ingredients have been added.
Six-pressure: press hard after folding the wire to see if the rebound is slow.
Seven smells: mulberry silk quilt has a faint fragrance.
Advantages of silk
Silk is the lightest, softest and finest natural fiber in nature. After the external force is removed, it can be easily restored to its original state. The inner tube is not caked, tight, uniform and soft, and can be used permanently without turning over.
Silk is made of fine silk and has a novel fiber structure, so that water vapor can circulate freely.
Coupled with the unique air permeability and moisture permeability of silk itself, silk is more slippery, cool but not warm, warm but not dry.
Mulberry silk is mainly composed of animal protein, which is rich in 18 amino acids necessary for human body. It can promote the vitality of skin cells, prevent vascular sclerosis, prevent skin aging after long-term use, have special antipruritic effect on some skin diseases, and have certain health care effects on arthritis, scapulohumeral periarthritis and asthma.
Known as "the second skin of human body" and "the queen of fiber".
There are various carotene derivatives in yellow cocoon, which are also cocoon colors such as yellow orange, pink and brown gray.
Washing and maintenance of silk
1 Silk should be washed with neutral detergent. After washing, it can't be twisted or exposed to the sun, and it can be hung naturally to dry.
When washing mulberry silk, if you can add a spoonful of vinegar to the water, the washed fabric will be more colorful.
3 air-dry to 80% dry and iron at medium temperature. It is best to remove wrinkles. When ironing, the reverse side is facing up, keep luster, avoid spraying water and avoid water stains.
