The difference between mountain green and iron sheet, the difference between mountain green water an

It's just that the color is different. The mountain blue is mostly green, and the iron grasshopper is mostly black. Comparatively, the cries of the iron gnats will be louder.

The green ones are the plain grasshoppers, and the iron grasshoppers are the mountain grasshoppers. The ornamental nature of green is high, and the cry of iron is better than that of green. The green ones can't live but the iron ones, so they are called general, and if they put one more piece of grasshoppers, they can't be called out if they are pressed green.

The most common on the market is the iron gnat, the adult body is like a black iron sheet, this kind of gnat is more adaptable, more resistant to low temperatures, and relatively large.

The body color of the mountain green grasshopper is mainly gray-green, the color is light and mixed, and the color of the head, abdomen and legs is not very uniform. There are three kinds of belly colors: green, yellow, and white, and it is the most common common grasshopper in the crop field, and when it is not moving, it looks like a wax product is bright and bright. The cries of the mountain green grasshoppers are crisp and loud, but there are fewer large ones, so they are also more expensive.

The mountain green grasshopper is relatively gentler than the iron grasshopper, and is not as fierce and strong as the iron grasshopper.

The main differences between mountain green and iron grasshopper are as follows:

1.Color: Yama blue is mostly green, while the body of the tin gnat, when it becomes an adult, has a black tin color.

2.Sound: Relatively speaking, the cries of the tin gnats are louder.

3.Adaptability: The iron coat is more adaptable, more resistant to low temperatures, and relatively large.

The difference between the mountains and the mountains is that the previous word "green" is the color of the mountain. Although the latter word "clear" has the meaning of clear, it is not appropriate to describe the mountain.

The former phrase is true, the latter is false.

They are all established in the 90s of the last century, the old Dendrobium leading enterprises, the main production areas are in Zhejiang, the quality is not much different, because the approval of the drug brand, the sale is more expensive, Senshan is relatively more cost-effective.

Are Zhejiang old iron maple bucket enterprises, maple buckets are Zhejiang, Yunnan high-quality dendrobium processing, the content of the ingredients may be slightly different, at present, the production of vertical drills is larger, Senshan market share is higher.

It can be distinguished in the following ways:

First, the chemical composition is different.

1. White iron sheet: It is the common name of galvanized iron sheet. Mild steel sheet with galvanized surface.

2. Steel: a general term for iron-carbon alloys with a mass percentage of carbon content between to.

Second, the main ingredients are different.

1. White iron scale: the main components are strong ductility of iron (iron: chemical symbol FE relative atomic mass 56) and zinc (zinc: chemical symbol ZN relative atomic mass 65) alloy.

2. Steel: Steel is an iron-carbon alloy with a carbon content between %. We usually refer to it as steel together with iron, and in order to ensure its toughness and plasticity, the carbon content generally does not exceed.

In addition to iron and carbon, the main elements of steel are silicon, manganese, sulfur, phosphorus, etc. The other components are designed to differentiate the properties of the steel.

Third, the characteristics are different.

1. White iron sheet: not easy to rust and corrosion resistance. It can be used to make roofing, coiled pipes and various containers.

2. Steel: Steel has become one of the most used materials in the world with its low cost and reliable performance, and is an indispensable ingredient in the construction industry, manufacturing industry and people's daily life. It can be said that steel is the material basis of modern society.

Distinguish from the differences between the two, as follows:

First, the use of the two is different:

1. The use of white iron sheet: an iron coil widely used in industry and manufacturing. It can be used to make roofing, coiled pipes and various containers.

2. The use of steel plates: widely used in bridge steel plates, boiler steel plates, automobile manufacturing steel plates, pressure vessel steel plates and multi-layer high-pressure vessel steel plates.

Second, the raw materials of the two are different:

1. Raw materials of white iron scale: the main components are alloys with strong ductility of iron (iron: chemical symbol FE relative atomic mass 56) and zinc (zinc: chemical symbol ZN relative atomic mass 65).

2. Raw materials of steel plates: After alloying elements are added to the steel, they mainly exist in the steel in three forms. That is: forming a solid solution with iron; carbides are formed with carbon; Intermetallic compounds may also form in high-alloy steels.

Third, the overview of the two is different:

1. Overview of white iron sheet: white iron sheet is the common name of galvanized iron sheet. Mild steel sheet with galvanized surface. The thickness is generally millimeters, and the thickness of the zinc layer is greater than millimeters. It has the advantages of not being easy to rust and corrosion resistant.

2. Overview of steel plate: a flat steel made by pouring molten steel and pressing it after cooling.

White iron sheet is the common name of galvanized iron sheet. Mild steel sheet with galvanized surface. The thickness is generally millimeters, and the thickness of the zinc layer is greater than millimeters.

It has the advantages of not being easy to rust and corrosion resistant. It can be used to make roofing, coiled pipes and various containers. Stainless steel is the abbreviation of stainless acid resistant steel, and the steel grade that is resistant to weak corrosive media such as air, steam, and water or has stainless steel is called stainless steel; The steel that is resistant to corrosion by chemically corrosive media (acid, alkali, salt and other chemical corrosion) is called acid-resistant steel.

There is no difference between iron sheet and steel, but the name is different. Iron sheet is also a type of steel.

The difference between white iron sheet and steel is that white iron sheet is a thin steel plate with zinc plating.

White iron sheet is another name for galvanized iron sheet, and some people also call it Lao round iron; Generally, the thickness is less than 1 mm, and the material contains less carbon, so it is softer and easy to bend, and it is used more for civilian products, and is mostly used to make chimneys, buckets, kettles, etc.

Steel plate generally refers to the iron plate with a carbon content of more than 30, or a special-purpose steel plate doped with rare metals (MN, NI, SI, etc.), which has a high hardness and is not easy to bend after quenching, and is used more in industry, such as manganese steel sheet or high-carbon steel sheet to make sheet springs, air compressor valve plates; Silicon steel sheets make transformer cores and so on.

First, the morphological characteristics are different.

1. Dendrobium vulgaris: the stem is erect, fleshy and thick, slightly flattened cylindrical, 10 60 cm long, up to cm thick, the upper part is more or less folded and curved, the base is obviously narrowed, not branched, with many nodes, and the nodes are sometimes slightly swollen; The internodes are more or less inverted conical, 2.4 cm long, golden yellow when dry. Leaves leathery, oblong, 6 11 cm long, 1 3 cm wide, apex obtuse and unequal 2-lobed, base with stem-hugging sheath.

2. Dendrobium officinalis: stem cylindrical, 9-35 cm long, 2-4 mm thick, unbranched, with multiple nodes, internodes long cm, often 3-5 leaves alternate above the middle; leaves bi-rowed, papery, oblong-lanceolate, apex obtuse and somewhat hooked, base extended below the sheath of the stem, margins and midribs often lavender; The leaf sheath is often purple, and its upper edge is loose from the stem and open in old age, and leaves a ring-shaped iron-green gap with the node.

2. Growth habits.

1. Common Dendrobium: Dendrobium likes to grow in a warm, humid, half-shade and half-yang environment. The requirements for soil and fertilizer are not strict, and the wild mostly grows on loose and thick bark or tree trunks, and some also grow in stone crevices.

2. Dendrobium officinalis: suitable for growing in a cool, humid and unobstructed environment. Born on semi-shady rocks in the mountains at an altitude of 1,600 meters, it prefers warm and humid climates and semi-shady and semi-sunny environments, and is not cold-tolerant.

Third, the range of distribution.

1. Common Dendrobium: It generally grows in southern China. It is also distributed in India, Nepal, Sikkim, Bhutan, Myanmar, Thailand, Laos, Vietnam and other countries.

2. Dendrobium officinalis: distributed in southwest Anhui (Dabie Mountain), eastern Zhejiang (Yinxian, Tiantai, Xianju), western Fujian (Ninghua), northwest Guangxi (Tian'e), Sichuan, southeastern Yunnan (Shiping, Wenshan, Malipo, Xichou).

The difference between Dendrobium and Dendrobium: There is a big difference between Dendrobium and Dendrobium, don't make a mistake.

The difference between ordinary dendrobium and dendrobium is that the material is different, so there is a difference between them.

There are a total of 76 varieties of Dendrobium, only 3 kinds can be used in medicine in the past dynasties, Dendrobium officinalis is one of them, the best of which is Huoshan Dendrobium or Wenzhou Dendrobium, ** chronic gastritis caused by stomach fever, yellowing of the tongue coating, has a miraculous effect, almost a dose of effect. Ordinary dendrobium, on the other hand, will harm the body.

Dendrobium officinale belongs to fairy grass, the stomach is not good, the tongue is yellow, and if it is an ordinary dendrobium, it will not work. This is the most important difference, what other active ingredients are appearances are, because in the wild state, there are all kinds of strange ones, and botanists will be mistaken, and only some old medicine farmers will recognize them.

Generally, it is difficult for us to buy fresh Dendrobium, most of them are processed dry Dendrobium, and some unscrupulous merchants use general Dendrobium to pass off as Dendrobium, and they can also be mixed after processing, making it difficult to distinguish.

However, Dendrobium officinale is relatively solid in appearance, easy to break, and the section is very uneven, without fibrous. The taste is with a faint grassy aroma, and the taste is light at first when chewing, with a sticky and slippery feeling, and the more you chew, the stronger the taste, and the viscosity will increase, so please pay attention to distinguish when buying.

There are a total of 1,500 species of Dendrobium in the world, 76 species of Dendrobium plants produced in China, including Dendrobium officinale and Dendrobium Huoshan as the top grade, its medicinal value is the highest, Dendrobium officinale leading enterprise Senyu Group has built China Dendrobium Geographical Park and China Dendrobium Museum in Yiwu, there is everything about Dendrobium and Dendrobium officinalis, you can go to see if you are interested.

There are many varieties of Dendrobium, the most prestigious of which is Dendrobium officinale and Dendrobium Huoshan (Dendrobium officinale (Dendrobium officinalis), there are often some black-hearted merchants in the market who use some laymen who can not see that Dendrobium officinale is similar to Dendrobium officinalis to be fake, such as: Dendrobium officinalis, Dendrobium officinalis, etc., the ** and medicinal effect of this Dendrobium is very different. Therefore, the "iron maple bucket" on the market is very low.

The development of Dendrobium officinale industry to the present, even the varieties of Dendrobium officinale are also different, and they will gradually be subdivided. Some varieties of Dendrobium officinale are suitable for fresh food, and some varieties of Dendrobium officinale are suitable for making maple buckets. First of all, look for a good variety of dendrobium.

In the end, it depends on the quality of this variety.

I don't think dendrobium is very good. It's just inducing some hot-headed people to rob the air! In fact, the beautiful flower dendrobium itself has all kinds of elements of dendrobium, but it is not the same

There are many kinds of Dendrobium, there are thousands of kinds in the global statistics, but so far there are 51 kinds of Dendrobium with medicinal and tonic value, of which there are 5 kinds of high recognition in the market, Dendrobium officinalis, Dendrobium officinalis, Dendrobium drumstick, Dendrobium nobile hairpin, Dendrobium purple.

Among them, Dendrobium officinale is the leader in Dendrobium, known as the "first of the nine fairy grasses", and its pharmacological efficacy is second to none among the five types of Dendrobium.

Dendrobium officinalis has a high polysaccharide content. Dendrobium polysaccharides are the main components of Dendrobium officinalis, and the content of polysaccharides is the main basis for judging the quality of Dendrobium officinalis. The Chinese Pharmacopoeia stipulates that the polysaccharide content of Dendrobium officinale shall not be less than 25%, the higher the polysaccharide content, the heavier the quality, the more viscous it is chewed, and the better the quality.

In those samples that met the traditional standard of "heavy quality, chewing sticky teeth, sweet taste, and no residue is preferred", the polysaccharide content was higher than 30%.

Dendrobium officinale is rich in dendrobium crude polysaccharides and dendrobine, anti-cancer and anti-cancer, etc., which are recognized by the medical community. On October 14, 2004, there was a professional report in the "China Medical News" that Dendrobium officinale can lower blood sugar and has a good improvement effect on diabetes.

Therefore, the irreplaceable medicinal value of Dendrobium officinale has established its status, and it will naturally not be particularly cheap.

At present, the popular Huoshan Dendrobium on the market is not Dendrobium officinalis, or there is a difference, everyone should pay attention to it when buying.
