The main uses of peat, the causes of the formation of peat

The formation of peat is the result of a combination of plant, hydrological, geomorphological and climatic factors, and is restricted by tectonic conditions.

Under the right conditions, peat can be further converted into coal (anthracite). The formation of peat is the result of a combination of plant, hydrological, geomorphological and climatic factors, and is restricted by tectonic conditions. Usually in a humid place.

The peat layer forms more quickly and the degree of decomposition of organic matter is lower, while the opposite is true in drier places. Many of the peat excavations found at high latitudes were formed 9,000 years ago, after the last ice age ended and the glacier retreated north. Peat layers like this form very slowly, even as little as 1mm thick per year.

Main ingredients:

In its natural state, peat is composed of three phases, which span the liquid, gaseous and solid phases. The solid phase contains two parts: "organic matter" and "mineral", if from the perspective of the constituent substance, the main component of "peat" is organic matter (that is, the main ** of carbon element), and the proportion of organic matter in the solid phase is the highest.

"Peat", which is composed of different substances, will have different physical and chemical properties. Basically, "peat" is rich in nitrogen, potassium, phosphorus, calcium, manganese and other elements, is a pure natural organic substance, it is a sterile, non-toxic, pollution-free, pollution-free, no residue green substance, can be used for many purposes.

The organic matter content is more than 30% (foreign countries believe that it should be more than 50%), the texture is soft and easy to crush, the specific gravity, mostly brown or black, with flammability and air absorption, the pH value is generally, it is slightly acidic reaction, and it is distributed in layers, which is called the peat layer.

Peat is an organic compound formed by the decomposition of residues from swamp plants. It has different types, but each type has a number of useful properties:

First, pay attention to the depleted soil and restore the soil after contamination.

Second, loosen the soil so that it retains water better.

Third, it is a natural fungicide – it removes bacteria from the soil and maintains a healthy flora.

Fourth, it is used as a thermal insulator.

Fifth, it is safe for the environment and can be used as a filter for natural water.

Peat is one of the few minerals with complex applications:

First, it is used as fertilizer in agriculture and as a substrate for growing various plants in greenhouses.

Peat soil II, used as a bedding material for raising animals, and as a covering material in landscape design.

Third, peat is used to make building insulation materials, and pressed panels are used for wall insulation.

Fourth, it is a raw material for the pharmaceutical and cosmetics industries. Peat is also used as a substitute for mud in many diseases, and the main exporter of peat to China is the Russian Federation. RPC LLC Russian Peat Company is a leader in this field, and the company's ** describes in detail the properties of peat and its uses.

Peat is mainly used in construction, potted plants, seedlings, raw materials, soil improvement, etc.

Brief introduction of three of themHere are three of them:

1. Architecture. Especially for rooftop gardens, peat is the only one, because the dry and wet weights of peat are 20% and 30% of ordinary soil, respectively, and are rich in nutrients.

2. Seedlings. In the seedling raising process of flowers and vegetables, peat can be used as the medium material and the substrate structure to cultivate seedlings, which can greatly improve the germination rate of seeds and improve the development quality and survival rate of seedlings.

3. Improve the soil. For the soil for planting flowers, grasses or other crops, if there are signs of compaction and hardening, as long as an appropriate amount of peat is added, the water-holding capacity, aeration and fertilizer retention capacity of the soil can be restored and improved, so as to improve product quality and achieve better economic benefits.

Peat and grass in our country refers to the same kind of product, are by the ancient low temperature, warm plant remains after tens of millions of years of accumulation of decomposition products, it is rich in fibrous matter, organic matter and humus, can repair degraded soil, increase the yield of crops, is a healthy and disease-free green material.

1. There is no difference

There is no difference between peat and peat, peat is peat, they are just different names, but they all refer to the same product, that is, the peaty soil of fibrous substances. In the north of our country, it is usually called peat, and in the south, it is called peat, so sometimes it will cause misunderstanding, but in fact, they are the same.

2. Import differences

Although there is no difference between peat and grass in our country, there is a difference in other countries. Imported peat is moss peat, which is the decomposition of bryophytes after death, and its air permeability and drainage are better, while domestic peat is generally grass peat, so unless it is imported peat, there is no difference between them.

3. **Source

Peat and peat, which are the decomposition products produced by the accumulation of plant remains in ancient low-temperature and warm regions over tens of millions of years. They are mostly brownish-yellow and light brown, distributed more in the northern part of our country, and will only appear in some low-lying valleys or under the surface soil in the southern region, and it is loved by people as a good cultivation medium.

4. Main value

Peat soil is a necessity for facility gardening, soil remediation, and functional fertilizer preparation in China, which is rich in fibrous matter, and has good ventilation and air permeability, and is a green material without germs, insect eggs and grass seeds. The organic matter and humic acids it contains can remediate degraded soils, reduce heavy metal pollution in soils, reduce the loss of chemical fertilizers, and improve crop yields.

In the natural state, peat is a lump, the water content is generally 80 90%, and the specific gravity of peat is general, and the constituent substances span the three states of liquid phase, gas phase and solid phase. Among them, the part of solid phase substances, from the perspective of constituent substances, the main components are organic substances (which are also the main ** of carbon elements) and minerals, and the proportion of organic substances in the solid phase is the highest. Peat with different composition characteristics has different physical and chemical properties.

According to the accumulation of soft plant residues with different degrees of decomposition, the organic matter content of peat accounts for more than 30%. Peat with low decomposition degree is mostly light brown and light brown, and contains a large number of plant residues. Peat with a high degree of decomposition is mostly black-brown and black, with a hard texture, an increased content of humic acid, and plant residues are not easy to identify.

The organic matter in peat is mainly cellulose, hemicellulose, lignin, humic acid, bituminous substances, etc. The content of humic acid in peat is often 10 30%, and the high can reach more than 70%. The inorganic matter in peat is mainly clay, quartz, and other mineral impurities.

Peat is usually divided into two types: high peat and low peat. High peat is formed by sphagnum moss, sheep's beard grass, etc., and is mainly distributed in alpine regions. High peat contains a lot of organic matter, has a poor degree of decomposition, has a low nitrogen and ash content, and has a high acidity with a pH of about 6 or more.

Low-lying peat is formed by the accumulation of plants with more inorganic salt nutrients, such as bryophyllus, Phragmites and alluvial plants, that need more inorganic salt nutrients in low-lying areas, seasonal water accumulation or perennial water accumulation. Low-level peat generally has a higher degree of decomposition, lower acidity, and higher ash content. The quality of low-level peat often varies greatly depending on the origin.

The structure of peat is: mud (left and right structure) and charcoal (upper and lower structure).

The structure of peat is: mud (left and right structure) and charcoal (upper and lower structure). The phonetic pronunciation is: 一 Pinyin is: nítàn.

What is the specific explanation of peat, we will introduce it to you through the following aspects:

1. Explanation of terms [click here to view the details of the plan].

Peat nítàn. (1) Coal with the lowest degree of charring.

2. Chinese dictionary.

The coal with the lowest degree of carbonization and the worst grade is closed. Similar to earth, it is black, brown or brown in color. Most of them are the residues of swamp plants that have not completely decayed and decomposed, accumulated over a period of time, and can be used as fuel, with low carbon content, and very little power in the burning fire.

Translation of words in English, peat, German, torf(s), French, tourbe

3. Network Explanation.

Peat peat is a natural marshland product formed over thousands of years (also known as peat, peat), is the coal with the lowest degree of coalification, and is also the most primitive state of coal, sterile, non-toxic, non-polluting, and good aeration performance. Light weight, water holding, fertilizer retention, conducive to microbial activities, enhance biological properties, rich in nutrients, is not only a cultivation medium, but also a good soil conditioner, and contains high organic matter, humic acid and nutrients. However, peat is a non-renewable resource, and the mining behavior is very damaging to the environment.
