Alfalfa grass has been in China since ancient times, but no one used it in ancient times, after all, ancient China has never been a country dominated by grazing, so although alfalfa has existed since ancient times, no one pays attention to it at all.

And in modern times it is different, alfalfa is one of the world's top ten forage grasses, known as the "king of forage", it has a very high protein content, not to mention, as a perennial herb plant, alfalfa nutritional value is extremely high, crude protein, vitamins, minerals are extremely rich, protein amino acid composition is very complete, animal essential amino acid content is high.

This thing can even reduce the amount of concentrate fed by cattle and sheep by more than 30 percent, which is modern and ancient!

There is an introduction to these alfalfa in the seed bank, there are several alfalfa seeds here, and the varieties stored by the state are all varieties that can be kept repeatedly.

For example, one is called Gongnongte No. 1, which is cold-resistant, drought-resistant, and can withstand low temperatures of -40 degrees, while the other is called Zhongwute No. 1, which is cold-resistant, high-salinity-tolerant, cold-tolerant varieties, and the yield is lower.

But for Li Ke, these things are quite effective now, and alfalfa people can also eat, and they are actually quite delicious, as a cold dish, for herdsmen, this is one of the important sources of vitamins and so on.

In addition, alfalfa also has a special role, which other pastures do not have, that is, this thing can fertilize the field!

The root system of alfalfa has a nitrogen-fixing effect, which may not be a small effect in modern times, but in ancient times, this thing has an obvious effect! The point is that the current Xizhou must be dominated by animal husbandry.

To be honest, Li Ke really didn't expect to unlock this, and among the five seeds in this warehouse, the remaining three are also very useful to Li Ke, namely pepper, cotton, and hemp, which contains seeds of flax, sisal, jute and other hemp crops.

However, since the repository has been unlocked, it is only a matter of time before the rest of the repository expands.

Pepper is planted to represent gold, but this thing can only be planted in Lingnan Road, and it seems that people should start preparing for deployment in advance in that place.

Not to mention hemp and cotton, the most important thing about these modern-bred seeds is the yield and the ability to resist harsh environments.

They are also a source of important textiles.

Tsk, today's harvest is too great, Li Ke took a deep breath, no, his strategic plan has to be adjusted.

However, the seed bank is different from the sugar warehouse, and the storage conditions of the seed bank are higher, so the construction scale of the seed bank is not as large as the sugar warehouse, but the seeds here are definitely enough for Li Ke for the time being, especially these seeds can be repetitive.

After reading these, Li Ke went to the underground warehouse to take a look, although the new warehouse was not unlocked here, but some of the previous warehouses were not fully unlocked, to see if there was anything new in it.

Speaking of which, Li Ke hasn't watched it for a long time.

When Li Ke entered the underground warehouse, there was not much change in the paper warehouse, and all the paper stacked was special for banknotes. The part used up by Li Ke to print the exchange coupon is simply a drop in the bucket.

On the contrary, in the warehouse of the banknote printing machine next door, Li Ke discovered something new.

Don't think about the banknote printing machine, Li Ke can't afford this thing in the next few years, but this new thing made Li Ke a little surprised.

This simple and stout thing looks very shabby, and it doesn't seem to be a strategic reserve, but the assembled parts show that it is very new, and there are a large number of wooden crates and other woven parts wrapped in oiled paper and covered with butter next to it.

This is...... Embossing machine!

And not a sophisticated modern stamping machine, but a simple manual stamping machine.

It's very simple, it's actually the same as the money printing machine that is also stored in this warehouse, but this embossing machine is used to press coins! There is an instruction manual next to it, and Li Ke picked it up and looked at it.

Soon Li Ke figured out how it works, it can press all kinds of coins, and there are several small machine tools that are used to engrave and press templates, hand-carved, and the other is a circular cutting machine, a grinding machine, all of which are operated by hand.

This thing...... He can also use it, if he recasts the Datang coin, it can be used, but it is different from this era in that it has no way to open a hole in the middle, and can only make copper coins that are almost the same as the coins of later generations.

But it doesn't matter.

The reason why the ancient money is square hole money is inherent in the ancient concept of the sky and the round place, but in fact, these ideas are only added by later generations, and the biggest factor that determines the shape of the copper coin is for its production convenience.

The round shape is to reduce the wear and tear in the use process, and the square opening in the middle has two functions, a mold casting process, in order to find the position of the font on the copper coin, easy to locate.

The second is that after the copper coin casting is completed, because it is a mold forging, its edge has many burrs, and the square can directly wear the copper coin on the square mold to fix, and then it is easy to polish, which is not as good as the upper hole whether it is a round hole or not.

That's the main reason, as for the idea of a round place, that thing is purely an afterthought.

It's like Mr. Zhou wrote, there are two trees in front of my house, one is a jujube tree, and the other is a jujube tree. Maybe Mr. Zhou just wanted hydrology, but later generations gave it countless interpretations.

It is not uncommon for the original author to be given a low score for reading comprehension in the articles he wrote.

This is a good thing, Li Ke is a little pleased, and there are a lot of things to see, which means that he can mint a large number of copper coins to use, the key is that this manual stamping machine can be said to be the simplest preliminary machine tool in modern times, this thing is handed over to the ancient craftsmen, compared to them can complete the study and imitate.

It can even be used to broaden their horizons, which is a good thing!

After checking the contents of this, Li Ke left the space.

It looks like my strategic plan is about to be adjusted! Come to think of it, my first five-year plan could have been more radical.

However, in the early stage of the monetary reform, it was necessary to let the family gate lords dig up the money they had buried, otherwise, the money in private circulation alone would not be enough to circulate, and it would be impossible to completely replace substitutes such as silk silk.

His own real estate plan can be started, of course, the real estate that Li Ke wants to play with has not been ready to play with the people from the beginning, nonsense, how much money do the people have? The real estate routine that Li Ke wants to play is to play with the gate valve family.

The number of five surnames and seven hopes is too small, although they are the representatives of the Datang gate valve family, but in fact, they can't represent all the gate valve families, how many gate valves are there in the Tang world? If you don't end these gate valves, why let them dig out copper coins!
