Yangzhou, the thirteen states of the Han Dynasty, has a total of six counties, of which Jiujiang and Lujiang are north of the Yangtze River; The four counties of Danyang, Yuzhang, Wu and Huiji are south of the Yangtze River.

In fact, the name of the Yangtze River at this time is one word - Jiang.

According to the habit of the Han Dynasty, the word "water" is convenient to call after the name of the river, that is, the Yangtze River at this time should be called Jiangshui, and the Yellow River is called Heshui, but for convenience, this article is still commensurate with the Yangtze River.

As for the geographical term Jiangdong, the area referred to in the Han Dynasty was the area south of the Yangtze River in the lower reaches of the Yangtze River, and in order to unify Yangzhou, Yuan Yao called the four counties south of Yangzhou Jiangnan as Jiangdong, which is slightly different from the so-called six counties of Jiangdong in the history of Eastern Wu.

The Jiangdong of Eastern Wu included part of the Lujiang River in Jiangbei, and Yuzhang County was divided into two, and Luling County was newly established, while Yuan Yao's did not, or it had not had time.

Yuan Yao's new Moling is a county in Danyang, which was renamed Jianye by Soochow and designated as the capital in history, and it was also the initial form of Nanjing when it became the national capital for the first time in later generations.

As for now, Moling is just an ordinary county seat, not even a county office, and it has no reputation at all.

Danyang County has 16 counties, which means that after all the occupation, the output of systematic clones will be 16 people per day.

Its county seat is in Wanling, which is the Xuancheng of later generations and the origin of the famous rice paper.

Although rice paper was produced in the Tang Dynasty and has not yet appeared, Yuan Yao has plans to use cloned artificial paper here, because the selection of rice paper is very closely related to the plants growing in the geographical environment here, so it must be conducive to papermaking.

However, Wanling's location is a little too inland, a little far from the Yangtze River, so Yuan Yao still plans to set his old nest in Moling.

After all, this is the ancient capital of the later Ten Dynasties, and the feng shui is better.

With Moling, it means that Yuan Yao has begun to hold his own territory, and it also means that he begins to need to "live at home" by himself, and all the money and food supplies need to be handled by himself, and there is no Nanny Liu Xun who is too guarded by Lujiang to serve.

And since he began to calculate the money and food, cold sweat has been constantly breaking out, and he even regrets the decision to provide the soldiers with three meals a day.

In the past, a soldier had two meals a day, and the food consumed was no different from that of a civilian, with an average of 1.5 hu per person per month, but after three meals a day, it became 1.8 hu.

It doesn't seem to have increased much, but it's only 3 buckets per person, but it can't stand many people.

Yuan Yao now has more than 70,000 soldiers to supply!

Although Yuan Yao was crossed, it seems that he still inherited Yuan Shu's habit of loving explosive soldiers, Danyang soldiers, Jingzhou soldiers, and all kinds of troops are not refused, and they will be accepted when they are caught, but after a few victories, the number of troops has more than doubled.

There was a supply from the Lujiang River before, but Yuan Yao didn't think about the problem of grain and grass at all, but now he was a little frightened when he thought about it.

Among the 70,000 troops, 20,000 belong to Lujiang, these Yuan Yao can not care, the remaining 50,000 are his own, with an average monthly consumption of 18,000 Hu per 10,000 people, and an annual consumption of 216,000 Hu, and 50,000 people is 90,000 Hu per month and 1.08 million Hu per year.

And the food that Yuan Yao has now is 300,000 Hu, or it has just been counted by snatching Liu Xuan, and he can only support it for three months just by eating.

And the military salary is not counted!

As explained above, the soldiers of the Han Dynasty were compulsory for military service and did not need to pay any fees, but the officers needed to pay salaries, otherwise they would not be able to control the army.

Yuan Yao calculated, according to the military system of General Zuo's Mansion, if each battalion of 10,000 soldiers and horses is complete with leading officers, it is necessary to pay 9,560 Hu per month to these officials, which is almost the standard of 10,000 Hu per 10,000 people per month, and 50,000 people is 50,000 Hu per month; 600,000 per year.

In this way, Yuan Yao's 50,000 army does not count the armor and equipment, and the monthly expenditure of 140,000 Hu is calculated only for food and salary; 1.68 million per year. Even if 50,000 of them could be paid in money every month, it would not be enough to feed the 50,000 troops with looted food alone.

So how much output can Yuan Yao's territory have?

Although Yuan Yao only occupied Moling County at this time, there was almost no suspense in taking the entire Danyang County.

Yuan Yao came from Shouchun, and Shouchun was the seat of Yangzhou, so the basic information of the counties in the territory was still recorded. When Yuan Yao was leaving, he had a copy copyed, but he never had a chance to view it.

There are 120,000 households and 630,000 people in Danyang County recorded in Shouchun. The cultivated area is about 3 million mu. The per capita cultivated land is less than 5 acres.

Today's agricultural technology, the average grain yield per mu is 3 Hu, that is to say, Danyang produces a total of 9 million Hu grain in one season.

Tianfu of the Eastern Han Dynasty has always implemented an ultra-low tax of thirty taxes and one tax, but Yuan Shu's territory has been changed to ten taxes and one tax, so his reputation is not very good.

However, Jiangdong has not changed the tax rate before, and it is still thirty taxes and one, so whether Yuan Yao wants to raise taxes is a question to be considered.

If the tax is not raised, the 30 tax can collect 300,000 yuan per quarter, which is far from Yuan Yao's demand.

If you have a tax rate with Yuan Shu and increase the tax to one of ten taxes, it will only be 900,000 Hu in that season, which is still far from enough.

If Jiangdong can only grow one season of grain a year like the north, then Yuan Yao will die.

So how many seasons of grain can be planted in Jiangdong in a year?

In later generations, Jiangdong was a land of fish and rice, with a higher yield of rice than corn, and it could be harvested twice a year, and even some rape could be planted in winter to increase income.

However, now Jiangdong is still in a semi-developed state, belonging to the wild land of the Central Plains population, rice is not qualified to become a staple food, and the main grain is still corn, so the rice that crops twice a year has not yet appeared. But like the Central Plains, it is in the stage of three crops in two years.

The introduction of wheat from the West was China's first "grain revolution", which allowed the Chinese people, who could only grow one season of corn a year, to plant one season of winter wheat interspersedly, so that the Central Plains region changed from one crop a year to three crops in two years, and increased grain income every two years, so that the population of China has been greatly increased.

China's second food revolution has not yet begun, but Yuan Yao does know the key factor that induced this revolution, that is, what he has always been thinking about - Champa rice.

Champa rice is a high-yielding, early-maturing, drought-tolerant rice variety produced in the Indochina Peninsula, which was introduced to Fujian in the late Tang Dynasty and then spread northward under the leadership of the Song Dynasty government.

Champa rice has many characteristics. First, it is drought tolerant and high yield;

the second is strong adaptability and is born regardless of location;

Third, the growth period is short, only more than 50 days from planting to harvesting.

Its outstanding and excellent characteristics have quickly become the dominant food crop in the Yangtze River Basin, and with the different geographical environment, a variety of new varieties have evolved one after another. Therefore, Champa rice has had a profound impact on the rice farming system in the Yangtze River Basin.

It was precisely because of the introduction of Champa rice that grain varieties that could be harvested twice or even three times a year, and the yield was twice as high as that of corn and wheat that could be harvested once a year, thus triggering the second "grain revolution".

In the early years of the founding of the People's Republic of China, the population of the country was about 50 million, and by 1200 A.D., 200 years later, it had exceeded 100 million, which was the first huge country with a population of 100 million in human history.

The land area of the Song Dynasty was less than half that of the Han Dynasty.

Therefore, if Yuan Yao wants to afford these tens of thousands of troops, in addition to continuing to expand his territory and increase his income, Zhancheng rice has become another decisive factor. It even determines the population of his future territory. The size of the population determines the upper limit of human cloning; The division of states and counties, as well as Yuan Yao's upper limit of life!

Therefore, Champa rice must be obtained, and the sooner the better!
