One part each of nitrogen, phosphorus and potassium fertilizer formula?

When Li Zhao heard this, he felt happy.

The growth of rice requires various trace elements, and nitrogen, phosphorus, and potassium are particularly important. The system is an urgent need to solve it!

It's like giving me a pillow for sleepiness.

The "fertile land" in front of us is barren. It is impossible to grow rice and increase the yield per mu. But with three fertilizers, it will be different.

In his previous life, when his family was growing rice, the three fertilizers were mixed in proportion, and the rice yield per acre was astonishing!

Accept it, of course I accept it.

Li Zhao knew that it must be Qin Shihuang's gift that triggered the system. This system was a trap for money, and he could no longer let it be kept.

I thought "accept" in my mind, and immediately a lot of information appeared in my mind, but it was just the formula of three fertilizers, but there was no "political economics" content.

But I’m not obsessed with it either. I learned “Political Economics” when I was in college in my previous life. It was very boring stuff like “production relations” and “productivity”, which made me dizzy just looking at it.

It's okay if you don't have one, so you don't have to worry about seeing that thing.

However, as soon as the thought came to an end, a book fell beside him. It was paper from a previous life. It had the words "Political Economics" written on it, but it was written in small seal script.

In his previous life, Li Zhao learned some small seal scripts when he was practicing calligraphy, and he could generally recognize them.

I sighed helplessly in my heart, the rewards from the system will never be too small!

But, why reward me with this thing? Could it be that I didn’t take it seriously when I was in college, so you created this thing specially to let me continue studying?

Li Zhao felt disgusted just thinking about it.

He hurriedly hid it. This thing was too new in Da Qin, and it was difficult to explain it if it was discovered.

"Li Shaonei, it's time to accept the order." Seeing that Li Zhao looked strange and moved furtively, Shang Xin quickly reminded him.

"Oh!" Li Zhao reacted and accepted the order.

After several servants left, Li Zhao ordered a dozen slaves to clean up the manor quickly, and then ordered a servant A Chao, who seemed to be quite smart, to exchange Qin Banliang.

Da Qin mostly used Qin Banliang. Gold was too valuable, so few people used it, and the amount was too large, so it was not suitable for use in transactions. On the contrary, Qin Banliang was much more convenient.

According to Da Qin conversion, one gold can be exchanged for more than 9,200 Qin and a half taels.

With Qin Banliang, you can receive three rice seeds.

Perhaps Ah Chao was familiar with the market and quickly exchanged the money.

"Master, this is thirty thousand Qin and a half liang." Ah Chao pointed to the three heavy bags of copper coins placed aside.

Li Zhao pondered for a moment, "Thirty thousand? In exchange for three golds, shouldn't it be more than twenty-seven thousand?"

"Master, the market has changed now, and one gold has increased to ten thousand."

Li Zhao was surprised and thought: If gold is exchanged for Qin Banliang, the price will also increase? Isn't it fixed?

He was a little unexpected. In the Li Mansion before, he didn't have to worry about all the expenses, and it was not his turn to worry about it. He didn't know some common sense about the market.

This is similar to the exchange of RMB for foreign currencies in previous lives! The exchange between currencies is related to a country's economy, and the exchange ratio also changes accordingly. Therefore, many people speculate in foreign exchange, and he is one of them.

"Doesn't this mean that Da Qin can also speculate on the exchange rate between Qin Banliang and gold?" Li Zhao thought to himself, but he was only excited for a moment. There are unknown things in the exchange of coins that are too big and uncontrollable. Having this idea and hanging his neck on it It's no different on the rope.

Unless he can control Da Qin's economy, this is completely impossible for him now.

After getting Qin Banliang, Li Zhao immediately went to the main room that had been packed. After thirty Qin Banliang disappeared inexplicably, he got three kinds of seeds.

Three hundred thousand rice seeds sounds like a lot, but there are only six bags in front of you.

It is impossible to plant a thousand acres of land with these six bags of seeds. He must plant part of the land first and then plant it after the harvest.

He didn't know whether the hybrid seeds in front of him were the latest two-ripe seeds bred by Grandpa Yuan, so he could only pray in his heart.

However, hybrids are too rare. If there is really a yield per acre that is nearly twenty times that of the current one, and it is not coveted by others, it cannot be shown to the world before its power has become prominent.

Don’t reveal your wealth in vain!

But what if he doesn't plant hybrid seeds and can't produce food within half a year? That doesn't mean he has to be beheaded. He doesn't want to be beheaded.

Fortunately, there are also Champa rice and Huanghuazam. Champa rice cannot be harvested twice a year, so it is not a good choice, but Huanghuazam is different. Although the yield per mu is not as good as that of hybrid varieties, the cycle is short! If it does not produce

Unexpectedly, the harvest can be harvested in four months, which is faster than hybrid varieties.

The yield per mu is also ten stones.

Good choice.

"Just plant yellow flowers!"

Li Zhao made up his mind and scanned the "fertile fields".

Thousand acres of land sounds like a lot, but it's actually not much. You can see the end at a glance.

"Who is that?" Li Zhao pointed at the middle-aged man and shouted, "Are you the leader?"

The middle-aged man is the older among the dozen or so people, and it seems that they also pay attention to the middle-aged man's instructions.

The middle-aged man was frightened and hurriedly walked over: "Master, I am from Pei County, Xiao. Due to family misfortune, I had to sell myself as a slave, so I was lucky enough to become the master's slave.

"They are not our pre-Qin people, but people from powerful clans in various countries."

"They will listen to my instructions for the time being. If the young master is not satisfied with the villain, he can, he can...change him."

The middle-aged man answered by analogy, but showed a trace of reluctance. It was obvious that he cared about his position as the leader.

Li Zhao nodded, glanced at the dozen or so people with a smile, stepped forward and patted the middle-aged man on the shoulder, "No need, you are very good. From now on you will be the butler of my Li Mansion."

Li Zhao still knew about slavery. After Qin Shihuang unified the six kingdoms, he captured many people from the six kingdoms. The court could not let them go and kill them indiscriminately, so becoming slaves was the best solution.

There are also some natives who will become slaves for some reason.

The faces of the dozen or so people showed vicissitudes of life and helplessness, and it was obvious at first glance that they had endured a lot of torture, their temperaments had been softened, and they had no home, so being a slave was the best choice.

"If you serve this young master well, the young master will be happy and it is not impossible to grant you such wealth."

The ten or so people were very excited. The young master said this because he treated them as human beings. Recalling that before, those people treated them as human beings and built Afang Palace. They were drafted. If they were not quick at work, they would be whipped.

smoke;

The construction of Epang Palace was temporarily suspended, and they were transferred to the Lishan Imperial Mausoleum. They were treated like this. If it weren't for special arrangements, they wouldn't be able to come here, and they wouldn't be able to become the young master's servants.

Moreover, the young master seems to be quite kind, and he will not be beaten or scolded at any move like other powerful men.

Of course, they don't dare to ask for wealth and honor, they just want a stable place.

"Don't worry, young master, I will serve you well." About a dozen people knelt down at the same time, with tears of gratitude.

Li Zhao lamented that as the first feudal centralized authoritarian society in history, these people are not as smart as humans in the 21st century, but this is fine, because it makes it easier to call them out.

Wait, Li Zhao suddenly thought of something and stared at Butler Xiao curiously.

"Are you from Pei County, your surname is Xiao?" He remembered that after the fall of Qin, Liu Bang took power and established the Han Dynasty. Three famous people appeared, known as the "Three Heroes of the Early Han Dynasty".

"Xiao He is one of them.

Xiao He was also from Peijun, and his surname was also Xiao.

Butler Xiao quickly bowed and replied: "Exactly!"

"Do you know Xiao He?"

Li Zhao vaguely remembered that he had studied Xiao He when he was studying the history of the Qin Dynasty. If his memory was correct, he should have been a young man and became an official in Pei County, which was equivalent to a modern personnel management position.

Butler Xiao opened his eyes, quite surprised.

"We know, Xiao He is the villain's nephew."

Li Zhao smiled and thought to himself how small the world is! Anyone he meets is the uncle of one of the three heroes of the early Han Dynasty.

"Young Master also knows him?" Butler Xiao asked cautiously.

Li Zhao waved his hand and said, "I just heard it!"

The matter was quickly revealed, and Li Zhao gave Qin enough half a liang to ask the housekeeper to arrange farm work, and also brought out three rice seeds.

However, it needs to be planted according to his instructions. First, cultivate an acre of land to cultivate yellow flower seeds. As for the hybrid seeds, he does not intend to plant them here. After all, this land is a gift from Qin Shihuang, and it shoulders the important task of producing eight stones per mu. It is better to let him know.

There are better hybrids out there, I really didn’t know they would be so predatory.

"We still need to buy a piece of fertile land and secretly plant hybrid seeds!"

As for Champa rice, we’ll talk about it later.

Da Qin attached great importance to agriculture. As slaves, most of them were familiar with farming, and these people must be the same.

Sure enough, Butler Xiao acted quickly and quickly ordered his servants to tidy up the manor and tidy up the thousands of acres of land.

Thousands of acres of land have too much loess and are obviously barren. Even if the water channels are unobstructed, high-quality rice cannot be grown. But with the three-fertilizer formula, it is different.

The next day, Li Zhao asked all the slaves to gather together. He was going to start looking for the raw materials of Sanfei. Whether it was picking up or buying, Sanfei had to be obtained.

In his previous life, the production process of San Fertilizer was too complicated and the raw materials were difficult to find. However, the formula given to him by the system was much more popular, more homely, and the raw materials were easy to obtain.

In fact, many things in life contain potassium, phosphorus and nitrogen, such as discarded fruit peels, rotten vegetable leaves, animal bones, swill, plant ash, etc. They can all be used as raw materials, but the process is more complicated.

He has plenty of manpower and doesn't care about the number of steps.

In his previous life, Li Zhao used scientific fertilizer. It can be said that the fertility of scientific fertilizer is the sum of various fertilizers. He decided to combine the three fertilizers together to make his own scientific fertilizer.

Of course, if various elemental mines can be found, the effect will be better. These are issues to consider later. First, plant the rice quickly. Qin Shihuang gave him half a year, and he did not want to be beheaded after half a year.

A few days later, a simple version of the scientific fertilizer was produced and put into use, and the seeds were planted. The next step is to see how it grows.
