Alfalfa has been present in China since ancient times, but no one used it at all in ancient times. After all, ancient China has never been a country mainly focused on grazing, so although alfalfa has been around since ancient times, no one paid attention to it at all.
But in modern times, things are different. Alfalfa is one of the top ten grasses in the world and is known as the "King of Forage." Not to mention its extremely high protein content, as a perennial grass plant, alfalfa has extremely high nutritional value. It is extremely rich in crude protein, vitamins, and minerals. The protein amino acid composition is very complete, and the content of essential amino acids for animals is high.
This thing can even reduce the amount of concentrated feed for cattle and sheep by more than 30%. This is for modern times, but for ancient times, this thing is concentrated feed!
There is an introduction to these alfalfa in the seed bank. There are several kinds of alfalfa seeds here, and the state stores all varieties that can be saved repeatedly.
For example, there is a variety called Gongnongte No. 1, which is cold-tolerant, drought-tolerant, and can withstand low temperatures of -40 degrees, while there is another variety called Zhonglute No. 1, which is cold-resistant, high-salinity-alkali tolerant, and cold-tolerant. The yield is lower.
But for Li Ke, these things are quite useful now, and alfalfa can also be eaten by people, and it is actually quite delicious. When used as a cold dish, for herdsmen, it is an important source of vitamins and other nutrients. one.
In addition, alfalfa also has a special function that other forage grasses do not have, that is, it can fertilize fields!
The roots of alfalfa have the effect of fixing nitrogen. In modern times, this effect may not matter, it is negligible, but in ancient times, the effect of this thing was obvious! The point is that Xizhou now is definitely dominated by animal husbandry.
To be honest, Li Ke really didn't expect to unlock this. Among the five seeds in this warehouse, the remaining three are also very useful to Li Ke, namely pepper, cotton, and hemp. Hemp includes flax. Seeds of sisal, jute and other hemp crops.
But now that part of the warehouse has been unlocked, as the warehouse expands, the remaining part is just a matter of time.
Pepper represents gold when grown, but it can only be planted on Lingnan Road. It seems that people have to 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 their yield and their ability to withstand 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. 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. However, the seeds here are definitely enough for Li Ke for the time being, especially these seeds can be repeated. Seed saving.
After reading this, Li Ke ran to the underground warehouse to take a look. Although no new warehouses were unlocked, some of the previous warehouses were not fully unlocked to see if there was anything new inside.
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. All the papers piled up were special papers for banknotes. The part Li Ke used to print the exchange coupons was simply a drop in the bucket.
On the contrary, Li Ke discovered something new in the banknote printing press warehouse next door.
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 like a strategic reserve, but its assembled parts show that it is very new, and next to it there are a large number of wooden boxes and other textiles wrapped in oiled paper and covered with butter. etc. parts.
This is...a stamping machine!
And not a complex modern press, but a simple hand press.
The thing it makes is very simple. In fact, it is together with the banknote printing machine also stored in this warehouse, but this printing machine is used to press coins! There was an instruction manual next to it, and Li Ke picked up the instruction manual and read it.
Li Ke soon figured out how it works. It can press various coins, and it is equipped with several small machine tools for engraving and pressing templates, hand-engraving, and a circular cutting machine. The grinders are all manually operated.
This thing... He can also use it. If the coins of the Tang Dynasty are recast, it can be used. However, what is different from this era is that it has no way to make holes in the middle. It can only produce copper coins that are almost the same as the coins of later generations. .
But that doesn't matter.
The reason why ancient coins have square holes is due to the ancient concept of a round sky and a square place. However, in fact, these concepts are just added by later generations. The biggest factor that determines 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 opening in the middle serves two purposes. During the mold casting process, it is used to locate the font imprinting position on the copper coin for easy positioning.
The second is that after the copper coin is cast, because it is forged by a mold, there are many burrs on its edges. The square shape can be directly fixed on the square mold, and then it is easy to polish. This does not matter whether it is a round hole or no hole. Not as good as the top hole.
This is the main reason. As for the concept of a round sky and a square earth, that thing is purely an afterthought.
Just 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. Perhaps Mr. Zhou just thought of hydrology, but later generations gave it countless interpretations.
It is not uncommon for the original author to receive a low score for reading comprehension of his own article.
This is a good thing. Li Ke is a little happy, and seeing that there are a lot of these things, it means that he can cast a large number of copper coins for use. The key is that this manual stamping machine can be said to be the simplest in modern times. Rudimentary machine tools were given to ancient craftsmen, who could learn and imitate them.
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 is about to be adjusted! Come to think of it, my first five-year plan could be more radical.
However, in the early stage of currency reform, you have to ask the aristocratic families to dig out the money they have buried. Otherwise, the coins circulating among the people will not be circulated enough, and it will be impossible to completely replace silk and other substitutes.
You can start your real estate plan. Of course, the real estate that Li Ke wanted to play with was not intended to be played with the common people from the beginning. Nonsense, how much money do the common people have? The real estate trick Li Ke wanted to play was with a wealthy family.
The number of the Five Surnames and Seven Hopes is too small. Although they are representatives of the powerful families in the Tang Dynasty, in fact, they combined cannot represent all the powerful families. How many powerful families are there in the Tang Dynasty? If we don't take care of these clans in one fell swoop, why should we let them dig out copper coins?
