Datang: Li Shimin begged me to rebel

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

It is different in modern times. Alfalfa is one of the top ten forage grasses in the world. It is known as the "King of Grass". Not to mention it has a very high protein content. Crude protein, vitamins, and minerals are extremely rich in content, and the protein amino acid composition is very complete, and the amino acid content necessary for animals is high.

This thing can even reduce the concentrate feed for cattle and sheep by more than 30.00%. This is for modern times, but for ancient times, this thing is concentrate feed!

There are introductions about these alfalfas in the seed bank. There are several kinds of alfalfa seeds here, and the national storage is all varieties that can be planted repeatedly.

For example, there is a variety called Gongnongte No. 40, which is cold-resistant, drought-resistant, and can withstand low temperatures of -[-] degrees, and another type is called Zhonglute No. [-], which is cold-resistant, high-salinity-resistant, and cold-resistant. Yield is lower.

But for Li Ke, these things are quite useful now, and alfalfa can be eaten by people, and it is actually quite delicious. As a cold dish, for herdsmen, it is an important source of vitamin maintenance one.

In addition, alfalfa has a special function that other forages do not have, that is, it can fertilize the field!

The root system of alfalfa has nitrogen fixation effect. Perhaps this effect is negligible in modern times, but in ancient times, the effect of this thing is obvious!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 flax, Seeds of various hemp crops such as sisal and jute.

But now that the warehouse has been unlocked, with the expansion of the warehouse, the remaining part is just a matter of time.

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

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

And they are also a source of important textiles.

Tsk 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 repeated Reserved.

After reading this, Li Ke went to the underground warehouse to take a look. Although the new warehouse was not unlocked here, 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.

After Li Ke entered the underground warehouse, there was not much change in the paper warehouse, and all the paper piled up were special paper for banknotes.The part used by Li Ke to print the exchange coupons 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 even think about the banknote printing machine, Li Ke won't be able to afford it in the next few years, but this new thing surprised Li Ke.

This simple and sturdy thing looks very crude and does not seem to be a strategic reserve, but its assembled parts show that it is very new, and there are a lot of wooden boxes and other textiles wrapped in oiled paper next to it, and it is covered with butter. and other parts.

It's... an embossing machine!

And it is not a complicated modern embossing machine, but a simple manual embossing machine.

The things it makes are very simple. In fact, it is the same as the banknote printing machine that is also stored in this warehouse, but this stamping machine is used to press coins!There is an instruction manual next to it, and Li Ke picked up the manual and read it.

Soon Li Ke figured out how it works. It can press all kinds of coins, and it is equipped with several small machine tools for engraving and pressing templates, hand engraving, and a circular cutting machine. Grinding machines are all manually operated.

This thing...he can also use it. If the Tang Dynasty coins are recast, it can be used. However, it is different from this era in that it has no way to make a hole in the middle, and can only produce copper coins that are almost the same as the coins of later generations. .

But it doesn't matter.

The reason why ancient money is square hole money is inherent in the ancient concept of round sky and earth, but in fact these concepts are only added by later generations. The biggest factor determining the shape of copper coins is the convenience of its production.

The round shape is to reduce wear and tear during use, while the square hole in the middle has two functions. In the process of casting a mold, it is easy to locate the font engraved position on the copper coin.

The second is that after the copper coin is cast, because it is forged with a mold, there are many burrs on its edge. The square shape can be directly threaded on the square mold to fix the copper coin, and then it is easy to polish. Not as good as the upper hole.

This is the main reason. As for the concept of round sky and earth, that thing is purely added later.

It is as if Mr. Zhou wrote that there are two trees in front of my house, one is a jujube tree and the other is a jujube tree.Maybe Mr. Zhou thought he was just thinking about hydrology, but people in later generations gave it countless interpretations.

It is not uncommon for the original author to be sentenced to low scores for reading comprehension of articles written by himself.

This is a good thing, Li Ke is a little delighted, and there are a lot of these things, which means that he can mint a lot of copper coins for use. The key point is that this manual embossing machine can be said to be the simplest in modern times. Preliminary machine tools, this thing is handed over to ancient craftsmen, compared to them can complete learning and imitation.

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

After checking the things inside, Li Ke left the space.

It seems that my strategic plan needs to be adjusted!Come to think of it, my first five-year plan could be even more radical.

However, in the early stage of the currency reform, you have to let the aristocratic families dig out the money they buried. Otherwise, the coins in the folk circulation alone are not enough to circulate, and it is impossible to completely replace silk and other substitutes.

You can start your own real estate plan. Of course, the real estate that Li Ke wanted to play, was not prepared to play with ordinary people from the beginning. Nonsense, how much money do ordinary people have?The real estate routine that Li Ke wants to play is with a powerful family.

The number of the Five Surnames and Seven Wangs is too small. Although they are representatives of the powerful families of the Great Tang Dynasty, in fact they cannot represent all the powerful families. How many powerful families are there in the Great Tang Dynasty?If you don't take all these elites out of the pot, why let them dig out copper coins!
