In fact, it is normal for a man to be fickle.

Not every man is as handsome as a handsome scholar, and he will be the same as a gentleman.

The same was true when Liu Mingqi was inventing the experiment.

The soap, flower essential oil, disinfectant alcohol, sugar, white rabbit milk candy, etc. he made at the beginning, and now he has no interest at all.

He couldn't be interested, including the bone porcelain that is now selling very well.

As for how much money he made, he didn't have any special feelings.

On this land, the most powerful thing is power.

As long as I am healthy, I will be almost the same if I have money or not.

After all, if a prince of the empire is not living well, isn’t he slapping the emperor in the face?

Except for money, everything else is actually within your reach, so Liu Mingqi doesn’t like money very much.

He is not a father.

In addition to money, can he also influence power?

cannot.

Just a little clamor, I was swept into the garbage dump of history... Well, if you don't believe me, you will see. When the dad comes out again, he will definitely be a beautiful young man with five talks and four stories.

What Liu Mingqi likes is to constantly invent and create more things.

Or discover something new.

For example, he discovered the treasure sweet potato that is constantly developing this year.

In fact, logically speaking, the earliest sweet potatoes should be relatively dry and not such a delicious rhizome plant.

It was only after thousands of years of cultivation and evolution that sweet potatoes became such a sweet food today.

But the sweet potatoes brought by Du Lifeng from Cebu Country are already very close to the modern taste.

Perhaps before that, the sweet potato roots brought by the birds had been cultivated!

No matter what, this is also a good thing. It won’t be that Liu Mingqi will have to cultivate for 10 or 20 years and make various optimizations before it can be launched into the market and let the people grow and eat it.

If it was really so slow, readers would have given up on this book long ago, so Liu Mingqi had no choice but to get out of here.

Sweet potatoes were cultivated in February last year, officially sown in April, and harvested in October.

Because Du Lifeng brought not enough sweet potatoes, the number of planting was only ten acres.

However, the average yield per mu of these ten acres exceeded 2,000 kilograms, which really made Emperor Jing and the important officials very excited, and they directly regarded it as the most advanced secret and project.

It is due to the quantity, the total sowing area this time is 400 acres, and they were all selected in the emperor's imperial farm for planting.

The person in charge was all farmers of Prince Yu's Mansion who had experience last year, but they were surrounded by people from the Ministry of Internal Affairs and the Embroidered Uniform Guards. No mistake was allowed, either the emperor or the court.

When the cultivation started in February this year, Liu Mingqi had already gone to the gates of hell. Now she is back in late September, and it will be harvested for about a while.

Liu Mingqi has all the information about sweet potato planting.

He asked someone to collect it specifically last year.

Don’t those farmers don’t understand culture?

Let them dictate the steps they have experienced, how they have done, and what special observations and discoveries are available every day.

Then the clerk records it, summarizes and screens it.

Liu Mingqi encouraged them to do it actively, and got together to discuss and exchange experiences and lessons.

If anything is discovered, they will try to change.

Don't think that farmers are ignorant.

The farmers on this land have a natural sense of smell for growing food and will definitely be able to do it well.

Aren’t the future production records of various grains created by our country’s farmers?

This year they also did this according to this rule.

So Liu Mingqi can see their various cultivation processes, planting processes, etc. this year.

There are many different places this year and last year.

First of all, there were only 20 to 30 kilograms of sweet potato stems per mu last year. This year, the farmers in Prince Yu's mansion boldly increased to 50 kilograms per mu.

This seed density was obtained after careful discussion and research.

Because after 20 or 30 kilograms of seeds were gone last year, there was still a lot of spare time in the fields.

Besides, Liu Mingqi told them that it is necessary to plant 4,000 kilograms per mu of land to be a preliminary success.

They felt that if they did not change, they would not reach a yield of 4,000 kilograms per mu, so they did it boldly.

At this point, I have to thank Liu Mingqi.

Liu Mingqi told them that they could use their ideas to the fullest without any scruples, and he would not pursue all consequences.

These farmers are all disaster victims recruited before and the family members of the Youth League.

They all became the dead servants of Prince Yu's mansion, so Liu Mingqi had absolute power to determine their life and death.

Since the little master has promised it, they naturally dare to do it.

Of course, the reason why these people followed Liu Mingqi's instructions was that Liu Mingqi's proficiency in agriculture made the farmers who had planted land for half their lives stunned.

What did Liu Mingqi tell them?

What is scientific "fattening" and "land cultivation"?

It talks about why fields are divided into upper-class fields, medium-class fields, lower-class fields, etc.

It also told them how the fields need to scientifically restore ground abilities and how to use them to maximize the fertility of the land.

Liu Mingqi is not nonsense.

How could his dignified doctoral in chemistry not know the role of chemical fertilizers, and how could he not study land-related knowledge?

The modern way to acquire knowledge is really too convenient, and this is also an advantage brought by technology.

Not to mention Liu Mingqi's knowledge about land checking is enough for others to accumulate thousands of years.

Just talk about reading.

Many books that ancient people read in their lifetimes are not as high as a modern person in a day.

I am talking about scholars, not farmers.

Therefore, after hearing what Liu Mingqi said, the experiences and lessons summarized by ordinary people, agricultural experts and scientists over the past thousands of years, a group of old farmers were fascinated by the hearing and regarded Liu Mingqi as the saint of the farmer family.

Let’s talk about sweet potatoes in detail.

Sweet potatoes have very low environmental requirements and can basically grow and develop except in extremely cold areas.

This is also the reason why sweet potatoes can become one of the main foods of human beings. All food crops with too harsh growth conditions have basically been eliminated in a long history. Every food that can appear on our dining table has been hard and struggled for thousands of years before it has not been eliminated.

But there are many requirements for growing sweet potatoes.

First of all, because the yield of sweet potatoes is particularly high, it must be a very harmful land.

This is the same as potatoes with similar yields.

Therefore, if you want to grow sweet potatoes for a long time, you need to rotate the land where the sweet potatoes are grown to a certain extent.

Of course, rotation alone is not possible. Many wheat and rice land are planted for one year, but if the land for sweet potatoes is not well managed and fertilized, it will not work the next year.

Wait a minute.

In modern sweet potato planting, there seems to be no planting every year!

This is very simple.

Because there were fertilizers at that time!

The fertility of chemical fertilizers replaces the fertility of the soil itself. Although it is also harmful to the soil, this level has been greatly reduced. Otherwise, how could my country's grain continue to grow steadily for decades?

But it was not possible in ancient times.

It is not impossible to invent things like chemical fertilizers, but it is too difficult to mass production. So many high-tech equipment, even in the 1950s and 1960s, cannot be made in this world now.

But there is no way.

After thousands of years of growing sweet potatoes, the people have a practical solution, basically without the need for what experts say, "The fertility in ancient times is not enough, and it is necessary to cultivate one round a year."

The method is also simple. After the sweet potatoes are harvested in October every year, farmers will sprinkle all the burnt wood ash and bone powder into the ground evenly.

That doesn't count.

One or two months in advance, you have to ferment and fertilize the farm manure and wheat straw together. Every time you wait about one month, you can plow the soil and then blend the fertilizer into the deep soil.

Such fattening, you will get it once after harvesting.

Then come again in early spring of the next year in February, so the fertility of the sweet potato field is enough for a year.

Of course, if conditions permit, ordinary people can plant some soybeans in the sweet potato field, which is also a good way to fatten the soil.
