Since ancient times, man has mastered agriculture and animal husbandry as the main economic activities.All products, which he received as a result of his work, used for clothing, household goods manufacturing and cooking.
Nature themselves with the origins of taking care of us and provides everything you need.Man, however, over time I learned to use it as widely gifts that today there is probably not a single representative of the flora, which had not been involved in any area of economic activity of people.
What plants in human life and the biggest play a significant role?Let's try to sort out this issue, describing the most common uses of herbal products.
Fields of use plant person
Of the currently known 340,000 species domesticated by man about 200 species of flora.A large part going to the wild habitats.This, for example, medicinal herbs.
total there are several key areas in which the useful plants are used for humans:
- medicine (both traditional and alternative);
- food industry (including confectionery);
- textiles;
- tailoring;
- chemical industry (production of dyes, various raw materials);
- decorative purposes (house plants, construction and design of buildings, streets);
- landscape design;
- use as a source of oxygen (in space, for example);
- plantations in the bands of the city to improve the state of the environment.
Thus, it turns out that the most important for a normal quality of life and human health areas of activity provided the raw ingredient from plants.This makes it possible to claim that to overestimate the role of flora for people difficult.
useful plants for human
such lots.For each area of its use.For example, in the chemical industry employ plants from which the natural dyes.In the same field of use is Hevea - tree sap which is a natural rubber.Useful properties of plants known to man since ancient times, and they are widely used.
food industry in general knows no bounds in the use of herbal products: from the different varieties of wheat, barley, rye and other grains to cultural fruits and root vegetables.After all, everything that grows in our gardens, used as food.Valuable proteins, fats, carbohydrates, vitamins, micro and macro person gets it from plants: rice, buckwheat, tomatoes, cucumbers, cabbage, potatoes, carrots, ocean algae, and so on. D., And so on. N.
Plantsin human life and play an important aesthetic role.Room types are widespread and numerous.In addition to beauty, they carry the ability to cleanse and refresh the indoor air, absorb and eliminate harmful effects of electromagnetic radiation and, to eliminate negative energy and clean the air of germs.These plants include:
- cacti;
- senpolii;
- Pelargonium;
- begonias;
- different kinds of ferns;
- euphorbias and other succulents, and so on.
Very important is the role of certain species of flora in the textile industry.You know how the plants are called, are "dressed" man and give him the towels, linens, scarves and other products of the industry?The main of them, grown on a large scale, are cotton and linen.Let us consider these and some other details.
From what plant tissues do?
There are several species of flora in the stems and leaves of which contain special bast fibers.They are for the manufacture of fabrics.What kind of plants that are "dressed" man?These include:
- Different types of linen.
- cannabis.
- Kenaf.
- abacus.
- Jukka.
- Agave.
- Kanatnikov.
- Jute.
- Sid.
- Sesbaniyu.
- Rami.
- Kendiry.
main part of them belongs to the tropical species.Linen, sida, hemp and Kanatnikov grow in temperate latitudes.
also important for flora fabric is cotton.Its seeds are formed thin white hairs that form a whole feather balls.Here are some of them, and made the most common, and excellent value for the quality of the future fiber fabric.
Cotton nature
Under natural conditions, this culture spread widely in different forms.People cultivate cotton even more 5000 years ago.This is not surprising.It received 40% of the world's tissue falls exactly on cotton.
plant is quite high (200 cm) stems shrub form.The leaves are medium-sized, with a cut beautiful leaf blade.Flower small, low-key color (yellow, white or cream).After flowering changes its color to red, orange or purple.In its place is formed fruit - capsule, which ripen seeds.
One fetus is able to produce about 50 seeds.In addition, each seed produces on itself to 15 thousand thin hairs, which are used to obtain tissue.View ripe fruit is very interesting: a box opens, and white cotton balls down displayed outside.At this time, and there is the harvest of technical culture for processing into fabric.
life forms
Cotton - plant heat-loving, water-loving and gentle.No wonder it is sometimes called "child of the sun."There are the following forms of life for him:
- wood;
- shrub;
- grass.
Each of them can be annual, biennial or perennial.For tissue grown annual shrub species.In the taxonomy belongs to the family Malvaceae.
Application
Cotton production in the world is over 25 million tons annually.It is carried out in 80 countries.The main applications of its course - as a source of high-quality, excellent technical characteristics of the tissue.
Plants that are "dressed" man, of course, include a list of cotton.Everyone knows the fine quality cotton clothing, especially if the material is combined with other additives which improve the wearability and prevents severe wrinkling.
As technical culture cotton is cultivated for a long time.Previously, wear clothes made from this material could afford only very rich people.Today, it is not a luxury, but things are basic necessities.Woven fabrics of cotton rugged, beautiful, easily colored, soft and pleasant to the body, wear-resistant.
For technical purposes
Cotton also used as the basis for:
- man-made fibers;
- pyroxyle;
- celluloid;
- varnishes;
- dynamite;
- smokeless powder and so on.
Len nature
best plants that are "dressed" person, include your list yet, and flax.Under natural conditions account for approximately 330 species of flora.The most common - flax ordinary.It is used to produce fibers.
Culture is a grassy shape up to 1 meter in height.Stems are strong but thin, lanceolate leaves, flowers are not large and medium-sized painting of the corolla pale blue, almost purple.In the wild there are species with bright yellow, white flowers.Flax - plant (photos can be seen below), in nature are quite common in temperate latitudes.
main value of flax is presented in its stem.That it ripen bast fibers allocated to the person's own needs.Collection of these stems only when fully ripe, that is yellowing.
The plant itself is very unpretentious.Calm brings low temperatures and lack of moisture, not attacked by pests because enough of the poison contained in the part of the stem and leaves.This makes the cultivation of flax is very convenient for people.
Application
Man is not only the stem of the species, but other parts.
- obtained from flax flaxseed oil (medicine, cosmetology, technical purposes).
- extracts from plants used in medicine.
- made from flax yarn specialized medical dressing (cotton wool, bandages).
- Fabrics made from this plant can be thin and lacy, and may differ extraordinary strength and brutality (burlap, canvas ships).
In addition, flax - a plant (photo illustrates this) is very delicate, so from an aesthetic standpoint, it is also very suitable for cultivation.
