Da Qin: Comparing his sons, Ying Zheng was sour.

Under the canopy, whether it is the monarchs and ministers of Daqin, or the heads of the world, or the children of peasant families such as Chen Xiang and Chen Xin, after listening to what the prince Fusu said, the Tianshi group.

Whether they understand agricultural research or not, they all have a feeling in their hearts.

That's professionalism!

Very professional!

Even if it is professional, even professionals such as Chen Xiang and Chen Xin, who specialize in farming, have to be ashamed of themselves.

How did the children of peasant families study farming in the past?

That is, at the time of farming, observe and record what factors are likely to cause a decrease in grain production and what factors are likely to increase grain production.

For example, factors that reduce food production include droughts, waterlogs, insect pests, and so on.

Then all the children of the peasant family will think about the solutions to these factors that may lead to the reduction of grain production.

After thinking of one or more feasible solutions, when they encounter the same problem again, a group of peasant children will try to solve it.

Eventually, if the solution they came up with, they recorded it and shared it with the peasant children.

For example, the use of plant ash to assist in tillage can make the land fertile and increase food production.

Then they will use grass ash on many acres of land for cultivation experiments.

If it is determined that the use of plant ash and the like can make the land fertile and increase the production of food, then they will also record it and share it with other farmers.

When the last group of peasant children instructed Qianshou to cultivate, they would pass on these cultivation knowledge that might lead to a decrease in grain production, or a possible increase in grain production.23

Is there a problem with this way of farming research?

No problem at all!

In this era, it is no problem for the children of peasant families who know how to conduct special research on fixed-point problems when studying farming, as well as record and summarize, to say that they are the light of cultivation in this era.

Even in terms of farming, the children of peasant families can be called a dimensionality reduction blow to the capital of Qianqian in the world!

However, if we compare the current method of farming by the children of peasant families with the research method of the Tenshi Group proposed by the prince Fusu on the canopy.

So in terms of farming, the prince Fusu on the canopy is also a dimensionality reduction blow for the current peasant children!

At least Chen Xiang, Chen Xin and other peasant children have never thought about the impact of different calendars on farming.

And will the different calendars have an impact on farming?

There will inevitably be an impact, even a big impact!

Because the calendar that is truly suitable for cultivation must be the time of heaven and the time of agriculture.

And because of the uniqueness of time, there should be only one set of such calendars in theory.

But now there are six different calendars!

Among these six sets of calendars, the "Yellow Emperor Calendar", "Zhou Calendar", and "Lu Calendar" all start with the sub-month (now November) as the first month of the year.

Therefore, the "Yellow Emperor Calendar", "Zhou Calendar", and "Lu Calendar" can be temporarily classified as the same set of calendars.

Even if the "Yellow Emperor Calendar", "Zhou Calendar" and "Lu Calendar" are temporarily classified as the same set of calendars, in addition to the "Summer Calendar", "Yin Calendar" and "Zhuan Calendar" with different years.

This means that at least three to five of these calendars are wrong.

And who dares to guarantee that the "Zhuan Calendar" that is now used by the Qin State must be the correct calendar?

Even if it were to the extreme, time had passed, and all six sets of calendars were wrong.

And if the time of the calendar they are using now is wrong, then can their cultivation under the guidance of the wrong calendar still be called the time of heaven and the time of agriculture?

And if you can't even do it when you should be in the sky and when you are in the next farming, then you still want a bumper harvest in the fields, I'm afraid it's not a dream!

It should even be said that in the case of violating the time of day and agricultural time, it is a fortunate thing that their land and acres have not been harvested.

And the prince Fusu on the canopy, under the Ministry of Agriculture, set up the Farming Division, and set up the Tianshi Group under the Agricultural Division, and divided into seven teams under the Tianshi Group.

Five of them were used to compare and observe the effects of different calendars on farming.

Among the current six sets of calendars, which calendar is the most suitable to guide cultivation, after a year, you can know by looking at the yield per mu of grain.

At that time, it will not be possible to determine which of the six calendars in use today will be correct.

But at least one of the six calendars can be chosen to be the most suitable for guiding farming.

And in addition to the fact that this is used exclusively to compare the different calendars, the effect on the cultivation of the five teams.

Prince Fusu also set up two other teams, either for researching, deriving, and summarizing the new calendar, or for dividing the four solar terms in more detail.

It can be said that Chen Xiang, Chen Xin and other peasant children are almost certain that in the future, the peasant children on the canopy will inevitably study and summarize a set of calendars that are more complete and accurate than the current six calendars.

At the same time, the four solar terms will be further divided.

In the end, the cultivation of the world's leaders will also be more reliably guaranteed!

And such a clear and very effective method of comparative farming research, why didn't they think of it before?

If they had thought earlier, they would have come up with a more complete and accurate calendar than the current six calendars.

But at least it is certain which of the six current calendars is best used to guide farming.

But after thinking about it carefully, Chen Xiang, Chen Xin and other peasant children shook their heads again, even if they thought about it, it was useless.

Because the children of peasant families also have to rely on the grain produced by the acres of land they cultivate to ensure their own food and clothing.

So even if they think of this very effective method of comparative cultivation, they will only be able to allocate a small percentage of the acres of land to the comparative cultivation study.

This kind of controlled farming research can be said to have greatly improved the efficiency of farmers' research in the past.

But compared to the study of comparative cultivation by Prince Fusu, the scale is too small, and the efficiency is too slow.

After all, Prince Fusu is backed by the Qin State, and he can carry out more than a dozen controlled research teams at the same time, or even dozens of controlled research teams.

At best, they are conducting several controlled research teams at the same time.

And this is still the case for the children of their peasant families, not to mention the others.

At least it is impossible for an ordinary Qianshou to have so many peasant children to help him like Prince Fusu.

Moreover, it is impossible for ordinary Qianshou to take out so many acres of land for experiments in order to test which calendar guides the cultivation of the most grain yields.

After all, the prince Fusu is the prince of a country, and his family is big.

Even if there was no harvest of the acres of land he used for experimental cultivation, it would be nothing more than an insignificant loss for Prince Fusu and for the Qin State.

But ordinary Qiantou, even if he loses the grain harvest of one acre of land, the family will have to starve in the coming year, and may even starve to death.

And the nobles were able to take out so many acres of land for experimentation, and the losses caused by this experiment could be borne by ordinary nobles.

But ordinary aristocrats also couldn't get so much help from peasant children.

And even if the nobles could get enough help from the peasant families, they would not necessarily be willing to experiment with such farming.

There are still too few nobles who can have a heart like Prince Fusu.

For the aristocracy of the 727 era, they did not care which calendar was more suitable for guiding agriculture.

Anyway, in the end, they don't need these nobles to farm.

As for whether the Qianshou will not produce much grain because of the wrong calendar used, this is not something they need to care about.

Anyway, if in the end, if the food collected by these nobles is less, then they can go and loot the Qianshou again, or increase the tax of the Qianshou.

As for whether the leaders who were scavenged by them for food or increased taxes would eventually die because of this, this is also not something they need to care about.

For the aristocracy, the head of this era is as cheap as a mustard, and if he dies, he will die.

Therefore, if you want to carry out large-scale agricultural cultivation research like the crown prince Fusu, then you must have a big nobleman who values the children of the peasant family and has the head of the Qian, or even a vassal state behind it.

Only a big aristocracy, or a vassal state, can continuously support the consumption of manpower, material resources and other resources required for such large-scale agricultural cultivation and comparative research.

And such a great aristocracy, or a vassal state, has never appeared before.

But now the appearance of the prince Fusu on the canopy is an opportunity!

Thinking of this, Chen Yuan immediately stood up from the ridge, patted the dust under his buttocks, looked at Chen Xin and said:

"Let's go, don't wait for the First Emperor to summon us, our peasant family will go to Xianyang to meet the First Emperor now!"

As long as they have the support of the Great Qin Shi Huangdi, their farmers will be able to carry out such large-scale agricultural cultivation research like the "peasants" on the canopy, and they will be able to further increase the grain output of the world's top Qianshou!

Chen Xin nodded and agreed:

"Okay, I'm going to gather all the peasant children now!".
