Tell the story of the officer's own story | XCMG and his "danger" view of the world

His name is Xu Miaofeng,

Deputy Director of Gongbei Customs Technology Center Plant Quarantine Laboratory,

Members of the General Office of the General Administration of Customs,

Members of the technical expert group of endangered plant products in and out of the country,

On weekdays, everyone is used to calling him "XCMG".

XCMG is mainly engaged in plant quarantine insect identification

And the appraisal of endangered species.

Repeated provincial and municipal scientific and technological awards,

And obtained three national invention patents, 3 items,

Published a monograph,

Published more than 40 scientific and technological papers.

Let's walk into the laboratory together,

Explore his "danger" view of the world-

As soon as I went to work, the customer service department sent a full car to check the sample,

There are flowers, ginseng, plant products ...

They were seized at the ports of Zhuhai -Macao.

After checking the inspection sample documents and quantity,

XCMG and colleagues are stored in different detection project samples.

According to insect identification, fungal identification, endangered species appraisal, etc.

Recently, the number of seedlings with seed seeds is large,

Such as cactus, succulent plants, orchids, etc.,

Some samples must also be identified by species.

"This is very similar to rock peony."

XCMG carefully picked up a lotus -shaped plant to distinguish it carefully.

Then, cut a small cut,

Prepare molecular identification.

Molecular identification is identified by the species's DNA sequence characteristics,

The accuracy is high.

Different from fresh species,

The appraisal of wood materials generally uses "seeing, smelling, ingening, cutting"

Look at the color, smell the smell, the amount of weight, cut the slices ...

"More appraisal, you can basically judge which major kind of wood you are at a glance,

Of course, it is also necessary to rely on micro -characteristics to make the final judgment. "

Don't underestimate this step,

Each wood should be cut into three noodles, cutting surfaces and cutting surfaces,

The fine features of wood are hidden in the three -cut surface.

The thickness of the thin piece is about 20 microns,

It is only about 1/3 of our hair diameter.

Drop the cut thin slices into the Tibetan tibetan chromatin,

Wash the excess dyeing agent with alcohol,

Take out the thin piece and place it on the glass with glycerin,

Cover with a glass piece,

The temporary thin slices of wood are made.

Finally, the sample information is required on the side of the glass,

For follow -up search.

Making glass pieces is a key step in the micro -appraisal of wood,

A stack of slides on the desktop is the recent results of XCMG.

The next step is to compare the machine,

Observe the structure of the plant cells carefully under the microscope,

Wood pipe holes, axial thin -walled tissue, wood rays, etc.

The structural characteristics must be kept in the heart,

Once you encounter uncommon types,

It also takes a lot of effort to read the reference book.

For species identification,

References can greatly improve the appraisal efficiency.

Put it neatly in the specimen room,

Over the years, XCMG and colleagues have made an interception item specimen,

Including hundreds of varieties such as insects, wood, seeds, etc.

From January to August this year,

XCMG and his colleagues have completed 333 batches of plant species appraisal,

Identifying the incense rosewood, sandalwood rosewood, rock peony, and mallet tree belong to

Endangumental plant species 11 30 batches.

Provide strong technical support for the smuggling of endangered species.
