"Sit." Li Ke pointed to the chair next to him, Fang Xuanling is here, and it is impossible for others to come over to attract attention.

After Fang Xuanling sat down, Li Ke asked, "If there is anything, Liang Guogong, you can just say it." ”

"That's right, Your Highness, the overall follow-up policy on Hanhai Prefecture has been almost formulated, but there is one thing I want to ask Your Highness, that is, whether these herdsmen in Hanhai Prefecture and the surrounding areas adopt the same policy as Qinghai, or do they formulate a completely new policy?" Fang Xuanling asked.

"What do you mean?" Li Ke was a little puzzled, hadn't this been discussed before? Overall, it's definitely the same as Qinghai.

"In terms of the division of pastures, do we follow the Qinghai state way and divide all herders into fixed pastures, let them graze their sheep, and let these herders switch from nomadic to fixed grazing, or do we formulate a new policy and still support their nomadic herding?" Fang Xuanling asked.

Li Ke frowned, this is indeed a problem, the entire Hanhai Prefecture is a little different from Qinghai, first of all, the population of Xue Yantuo is far lower than the herdsmen near Hanhai Prefecture.

The second is that the main areas of nomadism near Qinghai Prefecture before were the Hehuang Valley, Qinghai Lake, Chihai and other places, and then near the source of the three rivers.

To be precise, the nomadic area is not large, and after the herdsmen are fixed in these places, coupled with the strategic location of Qinghai Prefecture in the early stage, as well as the location of material transit, and the Hehuang Valley has turned to grow grain, so Qinghai Prefecture's grain replenishment has time.

But Hanhai Prefecture is different, the number of livestock in Hanhai Prefecture is calculated according to the population of Xue Yantuo, at least more than 30 million heads, if this number of livestock is fixed in the local area, then how to deal with the hay in winter?

Although alfalfa grass is a high-quality forage, there are not many eligible areas in the entire Hanhai Prefecture that can be planted, which means that the amount of forage that can be replenished in winter is not very large.

That's a huge amount of forage that these animals need.

Of course, it is not impossible to allocate land and fix the herdsmen's residences, and it can be combined with some distribution methods in later generations, but such a project amount is not a small number.

"I have a few options, but I'm not sure if I can do it." Li Ke thought about it, he is not omnipotent, whether he can execute it or not is unknown.

He also needs the world's experts to help him calculate.

"That's right, Tian Meng hasn't set off yet, has he?" Li Ke asked.

"Nope."

"Let's go, go to them, by the way, let people go to Li Yan and Li Shangshu, just say that I need a few professional people who can calculate, in addition, I asked Shi Yu to find a few in Qinghai Prefecture and come to Qinwangzhuang outside the city to find me." Li Ke said helplessly.

"Yes."

Naturally, Fang Xuanling didn't need to go to the notice, and handed it over to the guards to inform, and Li Ke took Fang Xuanling back to Qinwangzhuang.

He was a little helpless, hey, he was going to play in Qinwangzhuang for a few days, but as a result, Fang Xuanling came over, mainly because only Li Ke could handle this matter, which made people hurt.

After returning to Qinwangzhuang and waiting for more than an hour, the talents that Li Ke needed arrived here, and there were people who were better at calculating who were also listening to the side, and Tian Meng naturally came over.

"That's right, you who came back from Qinghai, have you calculated how much pasture is needed to feed a sheep, a horse and a cow? Give an approximate figure. Li Ke asked.

"Your Highness, this is not difficult, in fact, according to the number of cattle, sheep and horses in Tuyuhun that we counted before, and the amount of land we have counted now, we can probably calculate it." One man spoke at once.

"You give me an approximate number." Li Ke said directly.

The following people immediately began to take the relevant data and began to calculate, and they discussed a lot in the middle.

After about half an hour, one of them spoke: "Your Highness, according to our calculations, the area of grassland needed to feed a livestock is about 1,000-1,500 square meters. This is a comprehensive calculation, in fact, if you grow a high-quality pasture such as alfalfa grass, 50 square meters can feed a sheep. ”

"But if it is a pure natural grassland, considering that some very barren grasslands and grasslands with abundant water and grass require different areas, and the forage eaten by cattle, sheep and horses is also different, we estimate according to the proportion of cattle, sheep and horses of Xue Yantuo's original herdsmen that the average grassland area to support a livestock on the grassland must reach this figure to be able to fully feed." This person gave Li Ke a quick report.

(This figure is based on the actual number of pastures and livestock in Mongolia, because most of Mongolia still maintains primitive grazing methods, and ancient aquatic grasses are better than modern ones.) If it is land that is professionally cultivated for pasture, it must be much smaller than this number. In addition, the difference between pasture and pasture is very large. ）

"Hmm." Li Ke nodded, then turned to Fang Xuanling before they spoke, "Actually, there are advantages and disadvantages to the way they maintain their nomadism and the way they fix their residence. ”

"One of the reasons why the grassland people are nomadic is because they live in one pasture in the summer, and in the winter they go to another pasture that has not been eaten by cattle and sheep, and in the winter let the cattle and sheep find hay to live, basically chasing the river and living."

"Because cattle and sheep are equivalent to their living species on the grassland."

"The second is that the herders on the grasslands cannot be nomadic alone, nor can they be nomadic in a few families, and their nomadic groups are often relatively large. The main reason is to prevent a large number of wild animals on the grassland, and the second is the safety issue, and the small tribes between the grasslands often raid each other. Li Ke said.

"So, if we let them be nomadic, then if anything happens, it will be very difficult to find people, and then they will have less sense of belonging to our rule."

Li Ke opened his mouth and said, when he was in Qinghai, he had carefully understood the herdsmen of Tuyuhun, this era is very different from the grassland of later generations, the simplest point, the number of wolves on the grassland in this period is far beyond imagination.

Later generations had a population of 400 million at the end of the Qing Dynasty, and the population on the grassland far exceeded that of the current Tang Dynasty.

And in this day and age, one can imagine the number of wolves, as well as other wild animals.

In order to ensure the safety of themselves and their livestock, the herdsmen on the grassland cannot be nomadic alone, at least several families must graze together, otherwise safety cannot be guaranteed.

Another point is that there will always be natural disasters and man-made disasters on the grassland, take Xue Yantuo as an example, Xue Yantuo has an unknown number of small tribes under his name, if the livestock of a certain tribe has a natural disaster that causes a large-scale death, if the tribe wants to live, there will be a possibility of sneaking up on other small tribes around and robbing sheep, cattle and horses.

And the various tribes on the steppe are far away from each other, and these tribes fight each other, and many times the people above simply cannot stop it.

Of course, unless absolutely necessary, small tribes that belong to the same large tribe will not fight each other.

Therefore, if the current nomadic way is maintained, some policies of the Tang Dynasty will not be able to be implemented well, and Li Ke is ready to combine some of the policies of Inner Mongolia in later generations with some of the policies of the current nomadic herds.
