In autumn, the harvest season, farmers everywhere are busy with autumn harvest, while the students of IUZU, who are in Huaiyin, are also busy with autumn harvest - harvesting a large number of plant specimens.

They not only participated in the production of plant specimens (dry specimens), but also harvested a lot of "wet" specimens from production sites that specialize in plant specimens.

In the showroom, rows of glass jars were displayed on display one by one. The students stood in front of the shelves and looked at the millet, wheat, rice, beans, and alfalfa plants soaked in the glass jars, and were amazed:

All the plant specimens, roots, stems and leaves are actually in the original color (green), as if they were just pulled out of the ground!!

Moreover, some "series" specimens fully display several growth stages of the crop (taking grain crops as an example): seedlings, jointing, blossoming, ear formation, etc.

Scholars who do not distinguish between grains do not need to leave the city or go to the ground. By looking at these vivid specimens directly, they can have a clear understanding of the grain plants.

Add a picture album of "Common Plants Pictures" to provide a general understanding of common plants based on the plant legends on it.

Yao Cha, who worked as a PhD in IUC, held a thick "Common Plant Pictures" in his hand. He looked at the large number of "wet" specimens (infiltrating specimens) in front of him, and the curious students, and did not forget to remind him:

"If you don't distinguish between grains and you will recognize the picture and mistake during the exam, you will not be on the list."

Students all know that it is not difficult to recognize grains, just look at them carefully. However, the number of these specimens in front of you has exceeded the need to simply identify grains.

During the Eastern Wei Dynasty, there was a farm book called "Qimin Yaoshu", which included "Sowing Valley" and listed more than 80 millet.

Now, among the "wet" specimens placed on the display shelf, there are millet of different types (characteristics).

There are premature and drought-resistant varieties: Gaojuhuang, Liuzhuxie, life-sustaining yellow, etc. Because of premature ripening and early harvesting, they are not easily vulnerable to pests.

Some species have large thorns on their ears, which can resist the wind and avoid the pecking of birds. For example, now they fall into a car, get off the horse, and see a hundred sheep, hang their snakes with red tails, stop the tigers and yellows, and avoid the birds and folks.

There are medium-ripe varieties: hook dried yellow, Zhang Yibai, Geng Hu Huang, Du Nu Chi, Egg Reed Yellow, Fu Zhu Red, Wei Shuang Huang, etc. These are the most common medium-ripe millet planted.

There are late-ripening varieties: water black valley, suddenly mud green, soaring stick, pheasant green, geese head green, lingdui yellow, etc. This type of millet is resistant to rainwater, but not insect resistant.

Different types of millet have different characteristics: drought-resistant, water-resistant, wind-resistant, insect-resistant, tall and short stalks, strong and weak stalks.

Different regions, different climates, and different seasons are suitable for planting different millet. If you really want to describe it in detail, you can produce a thick book with the specific content.

The students looked at each specimen carefully and corresponded the names of the books to the "real objects" one by one, only to find it interesting.

Soon, everyone's focus was on how these specimens were made.

You should know that the "dry" specimens of plants that are now popular must not be able to ensure the emerald greenness of the original plants, such as leaves, because of the "dehydration" during the production process.

If the plants are soaked in water, they will definitely rot over time and will also change color.

However, the wet specimens in front of you are lifelike, the rhizomes and leaves are green, so what is the secret?

A student asked: "Doctor, students have also made this plant specimen, but they are all dry specimens. I wonder what kind of solution is used to soak the wet specimen, which can make the plants come to life and lush?"

Yao Cha knew the answer, but it was very troublesome to explain in detail. He couldn't explain it clearly for a while, so he answered:

"I used a green-keeping solution, as the name suggests, can keep the greenness of the plant specimens, but I don't know the specific ingredients."

So that's it, the students nodded and continued to watch the plant specimens.

There are indeed many students from wealthy families who cannot tell the difference between grains or only know "rice". After all, the rice is basically planted in Jiangnan.

As for millet, wheat, and millet, I only heard of their names but not their shapes.

Because of northern millet (wheat) and southern rice, people have never seen millet, wheat, or millet crops in many areas in the south, let alone identify them.

If you see a grain plant one day, I really don’t know which of millet, wheat, or millet is it.

Now, with the exquisitely drawn "Common Plant Pictures" and lifelike plant specimens, we can intuitively understand what the grains are.

Especially millet, millet ears are somewhat similar to dog tail grass ears. If someone doesn’t know millet, it cannot be recognized by just language and text descriptions.

If this is the case, it is easy to be fooled by people: putting the ears of dog tail grass and the ears of millet together, and it will make a joke if you can't tell the difference.

Now, it's different.

Not only are there various "wet" specimens, tea, hemp, mulberry, and specimens. Of course, because their plants are larger, most of the specimens are leaves and some branches.

These various plant specimens are lifelike, together with the "Common Plant Picture Book", and have become reading materials and "teaching aids" that students can gain knowledge while reading.

Yao Cha looked at the crop specimens in front of him and remembered the herbal plant specimens from the Medical School.

That was truly spectacular. There were countless display shelves displaying dense specimen jars, with thousands of them.

Among them, there are complete plants, or roots, stems, leaves, and some branches, so that students can understand the forms of various herbs without going to the wild to collect them.

Medical College is a newly opened school that specializes in training doctors and requires a large number of "teaching aids". These complete (relatively speaking) medicinal plant specimens come in handy.

Yao Cha's father, the Imperial Doctor Yao Sengyuan, served as a doctorate in the Medical School, teaching students and explaining medical theory and pharmacology.

With a large number of plant specimens and the newly-determined edition of the "Common Medicinal Plants" picture album, the time it takes for students to proficiently identify herbs is significantly shortened.

Therefore, the technology of making plant specimens (dry, wet specimens) has indeed brought a lot of convenience since its popularity.

The "public education" of the imperial court is more practical than in previous dynasties.

Of course, it is also very purposeful.

Yao Cha looked at the rows of millet specimens in front of him and thought of the current situation.

He had read "Qimin Yaoshu" and had an impression of the various crops listed therein.

Many of the crops mentioned in it, as well as millet and sorghum, are basically planted in the north and Guanlong areas.

Now, the court is so concerned about millet, wheat, and millet. It is obvious that it is to prepare for the future:

When the imperial court implemented management in Hebei and Guanlong, officials at all levels must be familiar with the local customs and crop planting.

Some people sent detailed workers from all over the country to spy on information and made the millet, wheat and millet from all over the country into specimens, which brought back the dazzling array of "wet" specimens in front of them.

It can be seen from this that today, I have been preparing for unification of the world.

Not only do we spy on news from enemy countries all year round, but we are also preparing for war in the country, such as promoting agriculture, increasing production and storing grain.

In the Taihu Lake area in Jiangdong, after large-scale water control, grain output has increased significantly. As a native of Wuxing, Yao Cha can confirm that the number of grain reported by local governments is not false or exaggerated;

In Huainan area, large-scale farming and rice cultivation have been planted. In Huainan and Henan areas, millet and wheat rotation have begun, and grain output continues to rise.

And according to the "Qimin Yaoshu", during the fallow land, bean (bean) crops are planted to restore the fertility of the land.

In addition to planting bean (bean) crops, it also planted forage grass - alfalfa. It is said that this forage grass can also restore land fertility.

Over the years, countless farmlands have been planted in the inter-cropping gaps in the Lianghuai and Henan. While restoring the fertility of the land, it has provided a large amount of forage for cattle and horses. Therefore, the scale of horse feeding has increased year by year.

The number of war horses will naturally increase.

Yao Cha came to a display stand, looked at the specimens of several alfalfa, thinking about the court preparing for war, and couldn't help but look forward to it: I don't know when the royal army will go north to fight?
