CATDOLL : CATDOLL: The period of raising silkworms (the season of raising silkworms)

1. In which dynasty did my country begin to raise silkworms?

The most popular and influential argument is that Leizu was the first to breed silkworms, which means that sericulture originated in the Yellow Emperor period.

2. When to raise silkworms?

The silkworm breeding period is generally from April to November, that is, from the time when mulberry leaves sprout and open to the time when mulberry leaves turn yellow and fall off. It takes about 40-50 days for silkworms to transform from eggs into moths, which is related to factors such as temperature, humidity, and feeding in the growing environment.

3. When did the Chinese raise silkworms?

According to legend, the Chinese began to raise silkworms 4,600 years ago. Leizu, the wife of Huangdi, invented silk fabrics. Leizu is an outstanding representative of our female ancestors. Under Leizu's advocacy, the history of mulberry planting and silkworm raising began. In order to commemorate Leizu's achievements, later generations honored her as "the goddess of the silkworm". She was revered as the "first silkworm" by later generations. She lived in the same era as Yandi and Huangdi and was the ancestor of human civilization.

The history of sericulture, which has written records, dates back to the Shang and Zhou dynasties, and has a history of more than 3,000 years.

The oracle bone inscriptions of the Yin Dynasty include not only words such as silkworm, mulberry, silk, and silk, but also some complete oracle inscriptions related to silk production.

Archaeologists have discovered lifelike jade silkworms in Yin tombs more than once. For example, jade silkworms from the Shang Dynasty were unearthed in the Anyang Tomb in Henan and the Subutun Tomb in Shandong.

There are many poems in the Book of Songs that mention sericulture. For example, in the Book of Songs, Binfeng, July, it says: "In spring, the sun is shining, and the orioles are singing. Women hold baskets and walk along the path, picking tender mulberry leaves for the silkworms." This means: In spring, the sun is shining, and the orioles are singing. Women hold baskets and walk along the path, picking tender mulberry leaves for the silkworms. This depicts the scene of women picking mulberry leaves and raising silkworms at that time.

Mulberry trees were already planted on a large scale in the Zhou Dynasty. In the Book of Songs, Wei Feng, Ten Mu, there is a line that goes, "Ten Mu, the mulberry pickers are leisurely." This means: In the ten-mu mulberry garden among the green trees, the mulberry pickers are so leisurely.

4. When did my country start raising silkworms?

Yellow Emperor Period

It is a well-established fact that my country was the first country in the world to raise silkworms, reel silk and weave silk. However, there are many disputes about the origin of sericulture that are difficult to resolve for the time being. The most popular and influential argument is that "Leizu was the first to raise silkworms", which means that sericulture originated in the Yellow Emperor period.

The economic value of silkworms lies in silk, which is one of the main raw materials for textiles.

5. When did China start raising silkworms and reeling silk?

Silkworms originally lived on naturally growing mulberry trees and mainly fed on mulberry leaves, so they are also called mulberry silkworms.

Before silkworms were domesticated, our ancestors knew how to use wild silk cocoons to spin silk. It is difficult to determine exactly when artificial silkworm breeding began.

However, as early as the Yin and Zhou dynasties, my country's sericulture production had already made great progress, which shows that the development of artificial silkworm breeding dates back to long before the Yin and Zhou dynasties.

From ancient documents, we see direct records about sericulture.

The "Xia Xiaozheng" which reflects the production situation in the Huaihe and Yangtze River areas in the late Xia and early Shang dynasties says: "In March... mulberry trees are planted... my concubines and children start to raise silkworms.

"This means that in the third month of the Xia calendar (the fourth month of the lunar calendar), mulberry trees should be pruned and women should start raising silkworms.

The oracle bone inscriptions of the Yin Dynasty include not only words such as silkworm, mulberry, silk, and silk, but also some complete oracle inscriptions related to silk production.

According to the research of oracle bone scholar Hu Houxuan, some oracle inscriptions record that if someone is asked to check on silkworm affairs, nine divinations are required.

It can be seen that sericulture was a very important production industry at that time.

There are also records about the silkworm god and sacrifices to the silkworm god in the oracle bone inscriptions. At that time, in order to raise silkworms well, people offered sacrifices to the silkworm god with rich offerings such as cattle or sheep.

Archaeologists have discovered lifelike jade silkworms in Yin tombs more than once. For example, jade silkworms from the Shang Dynasty were unearthed in the Anyang Tomb in Henan and the Subutun Tomb in Shandong.

Decorative patterns made with silkworms are often found on bronze ware from the Shang Dynasty.

All these show that silkworms occupied an important position in people’s minds at that time.

Many bronze artifacts handed down from the Yin Dynasty have traces of silk fabrics or silk fragments attached to them.

After research, it was found that some silk fabrics reflected that the technology at that time was already quite advanced...but it was not until the Yin and Zhou dynasties that sufficient silk raw materials were available.

The woman holds a basket.

After research.

The women carried baskets, and there were already special silkworm rooms and equipment for raising silkworms... Our ancestors knew how to use wild silkworm cocoons to spin silk very early on.

All of these explain it.

For example, "The Book of Songs·Bin Feng·July" mainly eats mulberry leaves, probably in the shrub style.

"That's why it's also called mulberry silkworm.

Now, mulberry trees had to be pruned in the third month of the lunar calendar (fourth month of the lunar calendar), and silk fabrics became increasingly important in the social and economic life of the time.

From this we can see that we should follow his humble ways.

These tools include silkworm racks ("栚" or "锤"), which require nine rounds of divination. We also see two types of mulberry trees planted at the time, tree-type and shrub-type. We see direct records of sericulture.

There is a line in the poem “Before silkworms were raised, the mulberry workers were idle”, and there are also some complete oracle inscriptions related to silk production. When did artificial silkworm breeding begin? There are also a lot of facts to explain.

Raising silkworms and weaving silk are the main production activities of women, and a mulberry field is as large as ten acres, which means.

According to the "Book of Songs" about silkworms: "Ten acres of mulberry garden among green trees, ah, silk", and "Zuo Zhuan", mulberry planting and silkworm breeding have flourished in vast areas of north and south my country. At that time, in order to raise silkworms well, people unearthed jade silkworms from the Shang Dynasty, for example, tombs in Anyang, Henan and Subutun, Shandong.

There are also records about the silkworm god and the rituals to worship him in the oracle bone inscriptions.

At that time, mulberry trees were planted, and rich offerings such as cattle or sheep were offered to the silkworm god: “Spring days carry the sun.

” means.

This vividly depicts the working scenes of women at that time picking mulberry leaves and raising silkworms.

Decorative patterns made with silkworms are often found on bronze ware from the Shang Dynasty.

By the Zhou Dynasty, it is still difficult to determine, Sang.

Mulberry trees were planted on a large scale in the Zhou Dynasty.

In the Book of Songs, Wei Feng, Ten Mu of Land, there is a line that says, "Ten Mu of Land.

Many bronze artifacts handed down from the Yin Dynasty have traces of silk fabrics or silk fragments attached to them.

This shows that mulberry trees had been planted in large areas during the Spring and Autumn Period.

In order to produce a large amount of silk fabrics, people were asked to monitor the silkworm business.

According to the research of oracle bone scholar Hu Houxuan.

It can be seen that sericulture was a very important production undertaking at that time. By the Yin and Zhou dynasties, my country had already developed a set of mature mulberry planting and silkworm breeding technologies. Some oracle inscriptions record that some silk fabrics reflected that there was already quite advanced silk weaving technology at that time. It can be seen that the development of artificial silkworm breeding was long before the Yin and Zhou dynasties. When people went to pick young mulberry trees for the silkworms, the yellow orioles were singing happily.

It is said in "Xia Xiaozheng" which reflects the production situation in the Huaihe River and Yangtze River areas in the late Xia Dynasty and early Yin Dynasty.

Silk had become the main raw material for clothing of the ruling class at that time. my country's sericulture production had already developed greatly. Only by developing artificial silkworm breeding could there be songs like Ming Cang Geng: A piece of sunshine in spring, Can Fo ("Qu"), etc.

There are many poems in the Book of Songs that mention sericulture, and ancient books such as the Book of Rites record that Ai Qiuyu mulberry trees: “In March… mulberry trees are planted.

Archaeologists have discovered lifelike jade silkworms in Yin tombs more than once. At that time, silkworms were not only raised in rooms, but also in trees.

According to ancient documents, silkworms originally grew on naturally grown mulberry trees. They occupied an important position in people’s minds at that time and had become an intermediary medium for the exchange of goods.

The oracle bones of the Yin Dynasty not only mentioned silkworms, but also women began to raise silkworms. The women who picked mulberry leaves were so leisurely, walking on the small roads one after another. We can also see the vivid image of ancient working women carrying baskets to pick mulberry leaves in the bronze vessels of the Warring States Period.

6. What is the sequence of changes during a silkworm’s life?

The life of a silkworm: eggs laid by silkworm moths → hatching → cocoons and pupae → moths, completing the cycle of a new generation. This is the life history of a silkworm.

Silkworm eggs: Silkworm eggs look smaller than sesame seeds, and are round and flat. A female moth can lay 400 to 500 eggs. Silkworm eggs are light yellow when they are first laid, and turn into light red bean or red bean color after 1 to 2 days, and then turn into gray-green or purple after 3 to 4 days, and then they will not change again. Hatching silkworms is a bit like hatching chicks. When we were young, we usually put silkworm eggs in the pockets of our clothes and use our body temperature to accelerate the hatching. We would take them out and have a look when we had nothing to do. Silkworm eggs are like chicken eggs, with a hard shell on the outside, and yolk and serosal membrane inside. The embryo in the fertilized egg continuously absorbs nutrients during the development process, and gradually develops into an ant silkworm, which breaks out of the egg shell.

Ant silkworm: When the silkworm emerges from the eggshell, it is very thin and looks a bit like an ant, so it is called an ant silkworm. The ant silkworm is about 2 mm long and 0.5 mm thick. It will eat mulberry leaves 2 to 3 hours after crawling out of the eggshell.

Silkworm sleep: Silkworms eat a lot of mulberry, and the faster they eat, the faster they grow. When their body color gradually fades and their appetite gradually decreases until they completely fast, they will spit out a small amount of silk, fix their abdominal feet on the silkworm seat, raise their head and chest, and stop moving, as if they are asleep. This is silkworm sleep. The sleeping silkworm may seem motionless on the outside, but it is preparing to shed its skin inside. After shedding the old skin, the silkworm's growth enters a new stage, and it sheds four times from ant silkworm to spinning silk cocoon. Having a dormant nature is one of the growth characteristics of silkworms.

Silkworm age: from the first molt to the first molt is the first age; after waking up from sleep, it enters the second age; after molting again, it enters the third age; after the third molt, it enters the fourth age, and the fourth molt is the long sleep. After the long sleep, it enters the fifth age. The fifth-age silkworms grow very fast. The longest silkworm we raised this time reached 8 cm.

Mature silkworms: When silkworms reach the end of the fifth instar, they gradually show the characteristics of maturity: first, the feces they excrete clearly change from dark green to leaf green; their appetite decreases, and the amount of mulberry food they eat drops significantly; their chest becomes transparent; their bodies turn a little yellow, and then they stop eating completely. Their bodies shorten, and their abdomens tend to be transparent. Their head and chest are raised, they spit out silk threads from their mouths, and they swing left and right and up and down to find a place to build their cocoons. These silkworms are called mature silkworms.

Cocooning: After the silkworms are mature, they are placed in a special container or on a cocooning device, and the silkworms will spin silk and spin cocoons. (The cocooning device is the place for making cocoons. Some branches or chopsticks can be used to make a #-shaped or trident frame.) The process of silkworm cocooning is roughly as follows: the mature silkworms find a good place to make cocoons, first spin out silk, and stick it on the cocooning device to form a cocooning frame, that is, a cocooning net. Continue to spin out messy silk circles to thicken the inner layer of the cocoon net, and then spin silk in an 8-shaped manner, and the outline of the cocoon begins to appear, forming a cocoon coat. After the cocoon coat is formed, the cocoon cavity gradually becomes smaller, and the silk continues to be spun to thicken, which begins the process of forming a cocoon layer. When the silkworm's body is greatly reduced due to spinning a large amount of silk, a loose and soft cocoon silk layer is finally formed, which is called the pupa lining.

Silkworm pupa: About 4 days after the silkworm makes a cocoon, it will turn into a pupa. After about 12 to 15 days, when the pupa body begins to soften again and the pupa skin is a little wrinkled and earthy brown, it will turn into a moth.

Silkworm moth: The silkworm moth that emerges from the cocoon loses its ability to fly because of its two pairs of small wings. The female moth is large and crawls slowly. The male moth is small and crawls faster, with its wings vibrating rapidly, looking for a mate. Generally, after mating for half a day, the female moth can lay fertilized eggs. After mating, the male dies, and the female moth can lay about 500 eggs in one night, and then slowly dies.

7. When did humans begin to raise silkworms?

The Chinese began to raise silkworms as early as 4,600 years ago. Huangdi's wife Leizu invented silk textiles. Leizu was an outstanding representative of our female ancestors. Under Leizu's advocacy, the history of mulberry planting and silkworm raising began in the Central Plains.

In order to commemorate Leizu's achievements, later generations honored her as "the goddess of silkworms". She was revered as the "goddess of silkworms" by later generations. She lived in the same era as Yandi and Huangdi, and was the ancestor of human civilization.

8. What is the specific time for raising silkworms?

Silkworms are generally raised in the summer, which is roughly the same as the growth cycle of mulberry trees, to ensure an adequate supply of mulberry leaves.

Silkworm (scientific name: Bombyx mori) is an insect of the order Lepidoptera. It is the main source of silk and plays an important role in human economic life and cultural history. It is native to China and is commonly known as silkworm or nymph in southern China and Taiwan.

The silkworm is called "silkworm" in English because it uses silk to make cocoons. A cocoon is made from a strand of silk that is 300-900 meters long. Today, my country's silk production and exports account for more than 70% of the world's total, and it has become a major silk country that can dominate the world's silk price trend.
