Why is cotton said to be a miracle plant that has moved the history of the world?

Cotton is not"Flowers", but the fruit of the withered flowers. So why is cotton a miracle plant that has moved the history of the world? What's so special about it?

Then I have to start with the ** of cotton, in ancient times, we in China generally used silk, linen, and kudzu to weave clothes, and the earliest cotton introduced into our country was African cotton, which was introduced into Xinjiang around the 3rd century AD. Then the earliest cotton was gradually spread outward through the exchanges between tribes and peoples of various countries, and it was transmitted to the Middle East through Ethiopia, Egypt, Iran, Iraq, Turkey, and Greece, and then from the west to the inland through Xinjiang. In this way, cotton connects several continents with **, and this intermediate bridge is cotton, and in the later development, upland cotton in Asia also flourished, and was introduced from Mexico to the south of the United States in about the 17th century.

This further illustrates the important role that cotton plays in increasing the world's connectivity.

It has been said that it was Indian cotton cloth that changed the fashion aesthetic taste of Europeans and improved their hygiene, and it is true that cotton was first cultivated in the Indian valley in the 4th and 5th millennium BC, and in the 1st century AD, Arab traders brought fine muslin to Italy and Spain, and it was not until the 9th century that cotton cultivation was introduced to Spain through the Moors. At the end of the 15th century, spices** opened up new shipping routes, and Europeans began to import cotton fabrics from India in large quantities, and because of their ease of cleaning, they became the first choice for underwear, albeit expensive. The cost of loss means that only the rich can afford to consume.

Before the same era, the use of cotton textiles had spread to the Mediterranean region. In the past 1,000 years, it is not an exaggeration to say that cotton manufacturing is the most important industry in the world, so cotton as an envoy has been of great significance in the history of world exchanges, and has also made great contributions.

Because cotton has changed human habits, the raw materials of many clothes are cotton, which is cheap and easy to wear, unlike the previous silk fabrics, which are very inconvenient.

Because cotton is the fruit of the withered flower, the flocculent fiber that protects the seed in the cotton peach (also called cotton boll). This fiber can be spun and woven after simple processing, and is one of the most important textile raw materials in the world. So put it this way.

With cotton, you can put on good cotton clothes and cover with good quilts, and cotton is the all-powerful person in this world. So cotton is really easy to use, and it accomplishes a lot of things.

Because of cotton, this plant, we humans can withstand the cold of winter even with very little hair, and it has an important guiding role in our civil circles.

Cotton is not the flower of a plant, it is the fluff that wraps around the cotton.

<> the flowers of cotton are milky white, turn crimson shortly after flowering and then wither, leaving behind small green capsules called cotton bolls. There are cotton seeds inside the cotton boll, and the hairs on the cotton seed grow from the skin of the cotton seed and fill the inside of the cotton boll, which splits when ripe, revealing soft fibers. The fibers are white or white with yellow, about 2 to 4 cm (inch) long, containing about 87 90% cellulose, 5 8% water, and 4 6% of other substances.

The countries with the highest cotton production are China, the United States, India, etc.

Cotton is not the flower of a plant, it is like the fruit of other plants, cotton bears fruit after flowering, and when the peach is ripe, it is cotton.

Hello, cotton is not a flower. When people talk about cotton, they generally refer to the fruit that grows after cotton blooms, and the internal fibers that turn out after the fruit ripens and cracks. And the so-called flowers are the flowers that bloom from plants.

The flowers that come out of cotton are creamy white or pink. Cotton is a detached dicot that prefers a warm, sunny environment. The nutrients consumed during the growth period are more, and the yield will be higher in the later stage when the nutrients are sufficient.

A: Hello, cotton should be the fruit of the plant.

Cotton is not the flower of the plant, but the fruit of the plant.

Cotton is the fruit of a plant, not the flower of a plant.

Cotton blooms, but it is also a crop. Flowers that do not belong to the plant category.

You. What do you want to ask?

What do you mean by "plants like cotton"?

I'll try.

Wild cotton is native to southern Asia, and its seeds have fibers that are meant to protect the seeds and facilitate seed dispersal (they can be blown away by the wind or stick to animals).But humans took advantage of this and used its seed fibers to make clothes, so they began to cultivate it and breed varieties with longer and thinner fibers. Because the original perennial cotton has grown for many years and has weak growth and reduced flowering, and is not suitable for cultivation in cold places in the northern winter, it has gradually cultivated annual varieties due to lack of limbs.

So we have today's cotton.

First, it is a plant Biologically speaking, cotton belongs to the genus cotton in the Malvaceae family, so there is no doubt that it is a plant. However, cotton used in daily life is not in the form of a plant. At this time, because it is actually some of the fluff produced in the fruit of the cotton tree, people separated this fluff and used it to make clothes and quilts, and called these fluff by the same name as the tree.

2. What are the varieties 1. White cotton: This is the most common category. Most of the cotton materials used in daily life are separated from this plant.

As its young plants grow up, it will enter a flocculent period, when many flocculent substances will grow on its plants, and they can be collected and used as raw materials for cotton production.

2. Color cotton: It is a new variety obtained by cultivating through technical means. Compared with traditional varieties, its biggest feature is that the floc spit out is colored.

Using it as a raw material can eliminate the need to dye white cotton, which is not only cost-effective, but also good for the environment. However, due to genetic instability, cultivation has not yet become widespread.

Cotton is a plant.

Biologically, cotton is a genus of cotton in the Malvaceae family, so there is no doubt that it is a plant. However, cotton used in daily life is not in the form of a plant. At this time, since it is actually a part of the fluff caused by the fruit of the cotton tree, everyone separates this fluff and uses it to make clothes and quilts, and calls these fluffs by names similar to those of the tree.

White Cotton: This is the most common type. Most of the cotton materials used in daily life are basically separated from this plant.

As its young plants grow up, it will enter a flocculent stage, at which time many flocculent substances will grow on its plants, and they can be collected and used as raw materials for the production of cotton.

Color cotton: It is a new variety obtained by breeding through technical means. Compared with traditional varieties, its biggest feature is that the floc spit out is colored.

Using it as a raw material can eliminate the process of dyeing white cotton, which can not only save costs, but also have great benefits for the environment. However, due to genetic instability, it has not yet been cultivated throughout the country.

The demand for light for cotton growth is very large, and it is necessary to ensure that there is sufficient light when planting cotton. When the light time is long and the intensity is appropriate, the cotton yield is high and the quality is good. If the light is insufficient, it will not only reduce the yield and quality, but also have a great impact on the subsequent seed retention work.

The magic of cotton lies in its high yield, low requirements for the growing environment, and very good warmth effect, which greatly increases the habitable range of human beings, and changes the course of world history.

In the era when there was no cotton, there were very few cold things available to human beings, most of the ancient Chinese used kudzu cloth and linen cloth to make clothes, and they could not resist the cold at all in winter, so the areas that were too cold for human beings could not set foot in, and civilization was mainly concentrated in places with relatively warm climates, not only because these areas were suitable for land cultivation, but also because we could not survive in cold areas. The best thing for the ancients to keep out the cold was fur, but it was difficult to obtain, so it was also very expensive, and ordinary people couldn't afford it.

The planting of cotton is relatively simple, does not require too fine operation, and still has great advantages in terms of saving manpower. The demand for cotton for the fertility of the land is not very large, and the conflict with agricultural land is very small, some idle land can be planted, and it will not destroy agricultural production in a large area, which is very important for the agricultural society, and no matter how good things are, they cannot be eaten from the mouth. The yield of cotton is relatively high, which also leads to its relatively low price, which can be purchased by ordinary people, has a good cold effect, and can be popularized in a wide range of people.

With cotton, people can survive in cold areas, and the expansion of the range of survival affects cultural exchanges, such as in the late Qing Dynasty in the Mohe area, the Chinese had contact with the Russians, and carried out extensive **, which was previously unimaginable. And then there is the conflict on the border, the scope of the war will continue to increase, just like the strategy game clicks through the fog of war, unlocks a new map, the scope of the game is larger, and the historical process has changed with the war game, the development speed of human society has been greatly improved, so cotton has changed the world pattern.

The most amazing thing about cotton is that it can be woven, it can be used to make different clothes, and it can also be used to make quilts to keep people warm.

It was with cotton that mankind began to obtain the raw materials for weaving, which could make clothes, which were lighter and more fitting than animal skins, and at the same time cheaper than wool, which brought world civilization into a new era.

Cotton solves the problem of human cold, so that people will no longer have to reduce their life expectancy because of cold.

Cotton can be spun, and then the thread can be woven into cloth, cloth can be dyed, and then made into various colors of clothing, so the magic of cotton is to make our clothes more colorful.

There are generally three kinds of cotton, one is the arbor type of kapok (such as Panzhihua and Huahua tree), the other is the unique shrub type of Hainan nucleated kapok, and there is our most common annual grass cotton.

Kapok is a specialty of China's ancient southwest region, and its textiles are called Huahuabu, but it is no longer passed on. Textiles of the Kapok are also found only in archaeological finds. Kapok and nucleated kapok have been eliminated in modern cultivated cotton.

What is the best plant to keep indoors.

Plants themselves are a rich life field, with a variety of the same system characteristics and performance shapes as humans, which can not only bring healthy body and mind to humans, but also have a great impact on us in terms of visual cues. Therefore, whether the selection and placement of plants are reasonable and correct will directly affect our health and work luck. Not all plants are suitable for placing in the home, and not all places in the home are suitable for plants.

It seems to be a simple plant, its selection and placement will bring a completely different luck to your home. Regardless of the size of the space, the kitchen should be equipped with a pot of plants, and good visual cues will determine the quality and health of our food, as well as the fortune of the whole family.

For smaller spaces, you can choose spider plants, which have the effect of absorbing harmful gases and kitchen moisture. Other suitable plants are: begonias, impatiens, pothos, geraniums, etc., pay attention to always place them in sunny local ventilation.

Then swing back to the original place, which is conducive to the growth and metabolism of the plant. The humidity, temperature difference, and smell in the bathroom are large, and placing the right potted plants is not only conducive to the growth of plants, but also beneficial to the health and fortune of the family.

The plants in the bathroom are ferns, weeping ficus, pothos, etc., which have the effect of absorbing dirt. The balcony is a place where the house is relatively empty, well ventilated, and has enough sunlight, which is suitable for placing all kinds of flowers and plants, but to have a function, it also needs to be carefully selected, which can be roughly divided into two functional plants.

If you look at it from the balcony, such as sharp corners, streets, bridges, chimneys, trees, hospitals, temples, etc., it is an inauspicious sign, and the visual hints will make the housekeeper easily excited, and the pressure will not be relieved, and it will constitute depression and other phenomena that are not conducive to the home.

If the objective conditions cannot be changed, then the evil must be resolved. Evil plants include: cactus, keel, rose, rhododendron, moon season, etc. If the balcony looks out and there is no invisible evil.

Plants that have a thriving effect should be placed to further make the family's work smoother. Flourishing plants include: evergreen, money tree, iron tree, palm bamboo, rubber tree, fortune tree, etc.

Generally, balcony plants that have a vigorous effect must be huge, thick and robust, and the better the growth, the better. There are basically two effects of placing plants in the entrance, one is to increase the vitality of the residence, and the other is to block the weather, so the evergreen plants should be placed to enjoy the leaves.

Plants are one of the main forms of life, including trees, shrubs, vines, grasses, ferns, and familiar organisms such as green algae and lichens.

Most of the energy of green plants is obtained from sunlight through photosynthesis, and temperature, humidity, light, and fresh water are the basic needs of plants for survival.

Seed plants have six major organs: roots, stems, leaves, flowers, fruits, and seeds. Green plants have the ability to photosynthesize - with the help of light energy and chlorophyll, under the catalytic operation of enzymes, water, inorganic salts and carbon dioxide are used for photosynthesis, releasing oxygen, absorbing carbon dioxide, and producing organic matter such as glucose for plant use.

In nature, all living organisms belong to living things. Organisms should be divided into several kingdoms, and the sedentary and autotrophic organisms are called the plant kingdom, referred to as plants.

Plants have distinct cell walls and nuclei, and their cell walls are made up of grapes.

Sugar polymers – cellulose composition. Plants have the ability to photosynthesize – that is, they can use light energy and chlorophyll that animals don't have in their bodies to produce food from water, minerals and carbon dioxide.

After the release of oxygen, glucose – an energy-rich substance – is left as a building block of plant cells. [1] Aristotle distinguished between plants (which are usually immobile) and animals (which often move to obtain food).

In the Linnaean system, it is divided into two kingdoms: the plant kingdom and the animal kingdom.

Later, it became known that the original definition of the plant kingdom included several unrelated taxa, and fungi and several species of algae were moved to the new realm. However, there are still many opinions about plants, both professionally and in the eyes of the general public.

It is also true that it is problematic to try to fit "plants" perfectly into a single taxonomy, because for most people, the relevance of the word "plant" to the concept of phylogeny, which is based on modern taxonomy and phylogenetic taxonomy, is not very clear, and the methods of reproduction are mainly striping, dividing, cuttings, grafting, seeds, etc.
