Outside Qu'a City, in a test field surrounded by the military camp, Bai Tu held the plow with one hand, and while driving the oxen in front of him to do the traction, he ploughed a crooked furrow in the field......

"Artifact! If you add a stupid cow, you can actually plow the land 'reluctantly'! Lu Lingqi was still walking next to Bai Tu dressed as a guard, and then whispered to him.

Bai Tu glanced at her, and maintained her image and ignored her - after all, Lu Lingqi's voice was also so low that others couldn't hear it.

The old farmers, cattle doctors and craftsmen who were witnessing this scene around were all excited and tearful at this time.

Originally, Bai Tu still felt a little great, but he just remembered what Lu Lingqi said, and then looked at their expressions...... It's really awkward!

It is true that Baitu ploughs the land not very well, and these people are excited...... It's really because Bai Tu plus a "stupid cow" can actually plow the land "effortlessly".

The so-called stupid cow refers to the buffalo, in the Eastern Han Dynasty, the buffalo was rarely used for farming, and most of them belonged to the so-called "vegetable cattle".

The main reason is that the buffalo is not as docile as the ox, and the size is nearly half larger, and it is difficult to use its animal power in the Eastern Han Dynasty, where the nose ring of the cow was not popular......

Therefore, in the Han Dynasty, it was only forbidden to kill ploughing cattle without permission - buffalo was not among them.

The south is mostly covered by buffalo, and arable land is inconvenient, which is one of the reasons why the population in the south is small at this time.

Cattle ploughing has appeared in the Spring and Autumn Period, and cattle ploughing has appeared in various places in the Han Dynasty, and even officially promoted it, but ...... Even in the north, the use of oxen to plough the land requires two oxen to pull a plow, and there are too few such "trenches" among the common people.

Now Bai Tu has made only two things - a curved plow and a cow nose ring.

Quyuan plough is the Tang Dynasty appeared, than the current long straight plow, more in line with mechanics, compared with more labor-saving, and easy to turn the tillage tools, until the Ming and Qing dynasties, but also still used the "artifact".

In the information of the white map, there is a specific record of the complete eleven components of the Quyuan plow, although it is only on paper, but with such a big guide, it is easy to get the finished product after repeated trials, and determine the manufacturing process of the specific components.

In contrast, the process of the cow nose ring is more complicated, because it is not a simple ring problem, but also how to wear it, in order to have the greatest effect and the least damage to the cow, otherwise ordinary people will not risk using the cow, and the buffalo will not work!

Therefore, Bai Tu also found a special old cow and cattle doctor - at this time, the person who treats the horse is called "veterinarian", and the person who treats the cow is called "cow doctor", and the classification is clear.

Now the white picture has finally fulfilled the plan, one ox, one plow, one person, can plough the land.

This is also the advantage of the curved plow, which only needs to be pulled by an ox, and the cultivator can hold the plough with one hand and a bamboo pole tied to the nose ring in the other hand to drive the buffalo!

Of course, in some fields that meet special conditions, there are more convenient cattle farming, such as two people and one ox, pulling a large plough farming method, but "single ox + curved plow" is already regarded as a "complete" form of animal farming.

There are many ways to improve farming efficiency, such as optimizing breeding, intensive farming, and water conservancy......

But these can only be done slowly, and now Bai Tu is just a temporary cram!

At the same time, Bai Tu also pointed out the decree of the "tuntian system", that is, the system of using the army, or servants, and landless people to cultivate official land in order to obtain military supplies and tax grain.

Unlike technology, the decree is important, and it is not necessary to make actual items, but to submit a report to the castle queen.

Usually, this kind of decree requires small-scale experimentation and constant adjustments, and finally can produce a report that can actually be adopted.

But for Bai Tu, the "tuntian system" is not so difficult.

In the time of Emperor Wen of the Han Dynasty, the original tuntian system had already appeared, but it was limited to the frontier - it was a supplement to the policy of "migrants to the border".

In the period of the Three Kingdoms, from Cao Cao's acceptance of Zaoyi's suggestion, the tuntian system began to prevail, the largest Tuntian, is the later development of Huainan by Cao Wei, the withered Huainan large area of uninhabited land is divided into official land, and then the combination of military tun and min tun collective cultivation.

The disadvantages of the tuntian system, Bai Tu is naturally very clear, first, the military tun occupies troops, no matter how it is distributed, it will occupy training time and reduce the elite degree of the army, and the real elite soldiers will not participate in the tuntian; Second, what is more serious is that the in-depth development of the tuntian system will almost inevitably get out of control to the point of seizing the people's land, especially when Baitu cannot restrain the family.

By the time of the Western Jin Dynasty, the tuntian system directly developed into a "land occupation system" that allowed gate valves to legally stake land.

However, for the sake of the advantages of the tuntian system and the imminent drought, Bai Tu felt that it was still necessary to first tuntun.

The purpose of the tuntian system has always been not to harvest much grain, but to enable the army to be self-sufficient, that is, to reduce transportation consumption, so the tuntian during the Three Kingdoms period was on the border.

For example, Cao Wei planned to attack Wu, which was in Huainan Tuntian, and Bashu wanted to enter the Central Plains, which was in Wuzhangyuan Tuntian......

The area where Baitu implemented Tuntian was also concentrated along the Yangtze River, and at first glance it really looked like he was preparing to seize Huainan, and only Baitu himself knew that this was to facilitate going to Huainan to save people.

As for Huiji County and Yuzhang County, which are far away from the Yangtze River, there is no need to tuntian, otherwise the efficiency of tuntian is lower than that of self-cultivation, and then counting the transportation consumption...... White toss!

In addition to food, the tuntian system also has two additional advantages, one is conducive to the harmony between the army and the people, from the perspective of human nature, that is, after the soldiers are accustomed to work, they will have more empathy for the people, which will avoid the soldiers from harming the people, and it is easy to develop a teacher of benevolence and righteousness; The second is to make the soldiers can start a family and start a career in the place of Tuntian, so that the soldiers have a greater sense of belonging, even if they are defeated in the future, they will try to come back.

The soldiers don't seem to have to think about this, but ...... After Bai Tu wrote the report, and then pointed out the decree of the tuntian system, he found that the "military tun" itself had an additional effect - after the implementation of the military tun, the military discipline was improved, and the army returned voluntarily after the defeat.

Of course, there is also a note: it will reduce the efficiency of training!

"Uncle, in the past few months, I have been living in the army for a while." Bai Tu said to several old farmers who had been invited.

This is also what I said before.

"Your Excellency, you're polite...... several old farmers didn't dare to do so.

"There is another thing, I want to study it with a few people, if there was a drought or flood locust plague in the past, and the grain harvest failed, what did your families eat to satisfy their hunger?" Bai Tu asked.

"I usually go to the mountains ......"

"Ahem, of course, there are local governments to provide timely disaster relief, and the county magistrates are very ......kind," said the eldest elder, preemptively.

"Honestly...... It doesn't affect the body too much! Bai Tu's brows furrowed.

"Ahem, that's usually bran and bran...... There are also several species of wild vegetables, grass roots, and sometimes tree bark. "The old man didn't want to talk about the white picture, but really asked for advice, so he said it.

"Well, then I will trouble you during this time, I will invite a few more doctors to come, and everyone will draw up a formula for disaster relief food, in short, it is necessary to save food as much as possible, and at the same time, it must not have too much impact on the body!"

The elders looked at each other, but they all responded one after another.
