Three days and three nights!
These three days, Jian Yong and Tian Chou were like they were injected with chicken blood, practically not closing their eyes.
They had been busy harvesting potatoes.
It wasn't just them.
After Guan Yu and Zhang Ren heard the news, they were so excited that they couldn't sleep that night. This caused their condition to be poor during training the next day.
After three days and three nights of harvesting, the final 50,000 mu of potato fields had an average yield of 28 dan of potatoes per mu. In other words, Liu Xuan had harvested a total of 1.4 million dan of potatoes in this round of planting.
According to the records of Dai County's Agriculture Division, there were a total of 500,000 mu of fertile land in Dai County.
Each mu of fertile land needed to be able to grow about 300 catties of potatoes.
If 500,000 mu of fertile land was used to grow potatoes, it would require a total of 150,000,000 catties of potatoes. If converted to stones, it would be 1,250,000 stones.
However, it was only October, and the next sowing date of potatoes was in February. There were still four months left. Including the two months of ripening time, there was a total of six months of empty time.
If all the potatoes harvested now were stored as seeds, the grain reserves in Dai County would definitely not be able to support the next round of potato harvest in April next year.
After discussing with Tian Chou and Jian Yong, Liu Xuan finally decided.
This time, they harvested 1.4 million stone potatoes. Only half of them were stored as seeds, and the other half was used as rations to maintain the development and construction of Dai County.
So far, Liu Xuan had basically solved the problem of food.
In February next year, he would plant seven hundred thousand stones of potatoes.
When the 250,000 mu of potatoes were harvested in October, Dai County would no longer be short of food.
Not only would there be no shortage of food, but there would also be a large amount of stored food.
It was already the middle of October.
In another month or two, autumn would be over and the cold winter would arrive.
Liu Xuan, who had solved the food problem in the future, did not relax.
Because!
He began to think about winter.
The cold winter was also a great challenge.
One had to know.
The commoners could not even afford to eat, let alone buy winter clothes.
People would die in winter!
According to the records of Dai County, nearly ten thousand people died of hunger and cold last year.
To Liu Xuan.
Every citizen of Dai County was his capital to conquer the Central Plains in the future. Not a single one of them could die!
Therefore…
What Liu Xuan was thinking about now was how to let the commoners safely survive the coming winter.
It was already too late to plant cotton. Moreover, planting cotton was not as simple as planting potatoes.
Liu Xuan currently had two ideas.
The first was to make coal stoves.
The price of the coal stove blueprint in the system store was not expensive. It only required 3,000 reputation points to buy.
However, the production of coal stoves required iron, and the current production of steel in Daijun was simply insufficient.
Thus, Liu Xuan directly ruled out this method.
He planned to wait for the next year when the steel production increased before making the coal stove.
Therefore…
He only had the second option left.
The second method was to find the Xianbei people in the north to buy sheepskin in large quantities and use sheepskin to make clothes for the cold.
This method was feasible.
The Xianbei people needed iron and food.
Among them, Liu Xuan would definitely not trade with them for the ironware. Selling it to them was equivalent to Zi Di.
However, Liu Xuan felt that he could use food to trade for furs.
At most, he would use some of the potatoes that were stored as seeds.
The advantage was that…
First, they could successfully exchange for a large number of furs, so that the people of Dai County could live a more comfortable winter this year.
Secondly, it was to make the Xianbei people give up on the act of pillaging in the south at the end of autumn and the beginning of winter.
The biggest reason why the nomads would go south to plunder before winter every year was that they had no food. They took advantage of the autumn harvest to snatch some food from the people of the Central Plains so that they could survive the winter in peace.
If Liu Xuan made a deal with the Xianbei people before they went south and gave them enough food for the winter, would they still go south to plunder?
No!
No!
Liu Xuan's goal was not only to exchange fur with the Xianbei people. He also wanted to buy a batch of horses with good bloodlines from them, and it would be best if they were stallions.
As for Liu Xuan's purpose in wanting to trade horses, I believe everyone could guess it.
Yes, that's right. Liu Xuan was preparing to form a cavalry.
Cavalry was the strongest army in the era of cold weapons.
An elite cavalry unit could often determine the direction of a war.
The importance of cavalry was self-evident.
