Is it true that the small leaved red sandalwood bracelet has black spots?

Black spot is due to the formation of a large amount of pterosandrin accumulation and precipitation in the growth process of small-leaved red sandalwood trees, some are punctate, some are linear, mostly in the form of annual rings, because of the seasonal changes in the growth environment and promote the occurrence of this phenomenon, there is no such black spot in the artificially planted red sandalwood, because the growth environment is superior, the nutrients are sufficient, the tree production cycle is fast, and the lack of harsh conditions is stimulated.

There are also cases where there are black tendons, and the small-leaved red sandalwood will lose water and produce cracks or even cracks after cutting, so these cracked parts will be exposed to air or rainwater, and will be rapidly oxidized to form the so-called black tendons, which are formed over many years, although they are easy to crack, but after long-term placement, they will gradually close, and the possibility of cracking again will be very small.

The small leaf red sandalwood bracelet has black spots or black lines, and it is not as high as the pure purple red bracelet. The main thing is that the material used to make the bracelet is limited. Bracelets with black lines and black spots are usually made from tree branches, and high-value small-leaved rosewood is made from trunk material, root material, and nodule material.

But the benevolent see the wise and the wise see the wisdom, some people like the black tendon black spots, because of the characteristics of the flame pattern, it looks like a strong contrast, very special, and the black spots are also a characteristic of the red sandalwood wild old material, a red sandalwood beads have a black line is not special, if the beads have a circle of black lines, it is very valuable, the whole is particularly beautiful, that is, the so-called "line of sky".

It is normal to have black spots, black spots are generally because the wood has been exposed to the air for a long time, and the place near the surface of the wood is oxidized by the air, and then the outer position of the bracelet is prone to black spots, and the black line is a very black single line or black coil, which is left during the growth of wood, innate, this black line is easy to crack, and the black spot will not crack. Hope mine is helpful to you.

Areas with dark spots are prone to cracking.

Hello, there are several reasons for the black spots on the leaves of Pterostilbene: 1. Iron deficiency. If the leaves are spotted due to iron deficiency, alum fertilizer water should be applied, or ferrous thioleuctoate solution should be sprayed.

2.Burns. Summer shade protects from the scorching sun.

3.Freeze. Rosewood microphylla is afraid of cold and should have warm measures.

4.Not in the sun for a long time. Poor ventilation makes the leaves roll bright and yellow with long spots, which are placed indoors during the day and moved outdoors at night.

5.Too wet. The soil is too wet and contains a large amount of root rot, which leads to long leaf growth.

Summary. The appearance of dark spots on the leaves of the small leaf of red sandalwood is caused by the appearance of pests and diseases on the leaves of the red sandalwood, and the specific conditions may be as follows:1

Bemisi tabaci: Bemisia tabaci are a common leaf pest that is small, like firework pollen, that lays eggs on the leaves of the rosewood and eats the leaves, eventually causing dark or brown spots on the leaves of the rosewood. 2.

Gray-white fungus: Gray-white fungus is a bacterial plant disease that forms grayish-white spots on the leaves of the red sandalwood, and the leaves around the diseased spots will turn yellow and may eventually turn into black spots. 3.

Rust: Rust is a common fungal disease on the leaves that forms tan, round, or oval spots on the leaves of the red sandalwood, which may eventually turn into black spots. When black spots are found on the leaves of red sandalwood, effective measures should be taken in time, such as liquid pesticides or pesticides, to prevent the further spread of the disease and damage the normal growth of the red sandalwood.

Poor ventilation makes the leaves dull yellow and long spots, put it in the room during the day, and the above is mine.

Can you elaborate on that a little bit more?

The reasons are as follows: lack of iron. If the leaves are long spots due to iron deficiency, alum fertilizer water should be applied, or ferrous sulfate solution should be sprayed.

2.Burns. Summer shade protects from the scorching sun.

3.Freeze. Rosewood microphylla is afraid of cold and should have warm measures.

1.Look at the color: The color of the real small leaf red sandalwood bracelet is white, slightly yellowish, and the overall color looks relatively uniform.

The longer you wear it, the more ruddy the color of the red sandalwood bracelet will be. False leaflet red sandalwood bracelets often have color spots on the surface, and the surface color distribution is uneven. The longer you wear it, the darker the color becomes.

2.Look at brown eyes: Brown eyes refer to wooden catheters, and they are also one of the significant features to distinguish the authenticity of red sandalwood bracelets.

The palm eyes of the true small leaf red sandalwood bracelet are thin and dense, and the shape is similar to cow hair patterns. When the small-leaf red sandalwood bracelet has brown eyes, but the shape is not cow hair pattern, or there is no cow hair pattern at all, it must be a fake small leaf red sandalwood bracelet. 3.

Weight: The density of a real small-leaf red sandalwood bracelet is very high. If it is composed of 15 5mm small leaf red sandalwood bracelets, the weight is about 35g; If it is a bracelet composed of 13 pieces of 18mm small-leaf red sandalwood, the weight is about 52g.

The fake small leaf red sandalwood bracelet is not really heavy because of the business of cutting corners. The real small-leaf red sandalwood bracelet has a certain pressure feeling in the hand, while the fake small-leaf red sandalwood bracelet is very light in the hand. 4.

Smell: If you really smell the red sandalwood bracelet closely, there is a faint fragrance, and this smell will gradually disappear after playing with it in your hand for a while. The smell of the fake small-leaved red sandalwood bracelet is pungent, and the smell will not dissipate after playing with it in your hand for a while.

After a long time, there will be a sticky feeling on your hands, which is very uncomfortable.

Density discrimination.

According to the physical knowledge, the density of water is less than that of red sandalwood, and if the wood to be identified is small-leaved red sandalwood, the wood will sink into the water. If it can sink in the water, then you can start the next step of identification.

Scratch identification.

Find an A4 piece of paper and a piece of wood that needs to be identified. Scratch the small piece of wood on the paper, if the piece of wood is small-leaved rosewood, then its scratch is red.

Alcohol discrimination.

Take a clear bottle and put half of the liquor in the bottle. When wood chips are put into the wine, if they are small-leaved red sandalwood, the chips will turn into pink-like particles and form a viscous liquid of water or alcohol. In addition, after soaking in alcohol with rosewood, the leachate is purple, which can be used to dye cloth and is not easy to fade.

This is the most accurate way to identify rosewood.

Odor discrimination.

When the small-leaved red sandalwood rubs against the object, it will have a faint fragrance. It smells more like the smell of burning wood, and some smell like inside a temple. Scrape with a knife or rub it during identification.

But if the aroma is too strong or not smelled at all, then it is half of it is not Pterostilbene.

and the distinction of blood sandalwood.

How to distinguish the authenticity of the small-leaved red sandalwood is a question worth discussing, and the wood most similar to the small-leaved red sandalwood wood is blood sandalwood, the two plants are intuitively very similar, so it is difficult to distinguish from ** alone, but ** is ten times different. The new blood sandalwood material is bright red, and it is dark red for more than ten days, and there is no fluorescent reaction. The color of the new rosewood is similar to that of an orange-red, and over time it will oxidize to a deep purple or blackish-purple color with dark streaks.

Rosewood microphylla is the best of wood, which is very valuable and at the same time very high. When choosing furniture or bracelets with red sandalwood, you should choose carefully and don't be deceived.

This trumpet should be a body.

It is unreliable to judge the advantages and disadvantages of a bunch of small-leaved red sandalwood by looking at the color black or red, all small-leaved red sandalwood will have an oxidation process from red to black, and the color black only represents a long oxidation time, but it does not mean that its growth age is long.

Looking at the quality of Pterostilbene, in fact, the most important thing is to see whether this material is an old material imported from India or a new material for domestic fast-growing forests. Good small-leaved red sandalwood, the content of pterostilbene is very high and very uniform, and the oily content is also high, so in the process of continuous play, as the beads continue to oxidize, its black will be very uniform, and the surface of the beads will be pure and will slowly present a glass-like effect.
