Potato.

Not a product of the Old World, it was native to the Americas, and it was not until Columbus arrived in the Americas that the Europeans came into contact with potatoes. But even so, it was not until twenty or thirty years ago that potatoes were brought back to Europe, defined as ornamental crops from the New World, and some aristocratic women used potato flowers as their valuable headdresses. At that time, potatoes were worth a lot of money, and ordinary people couldn't reach them.

In fact, like chili peppers, they were originally used as ornamental crops, and even nearly a century after they landed in Europe, potatoes were the case, and it was not until almost two hundred years later, in the seventies of the eighteenth century, that potato cultivation was popularized on a large scale in Europe.

When were potatoes introduced to Daming?

Shi Yiwen didn't know, and he didn't know if there were potatoes in Shanglin Yuan. But even if there is, it doesn't matter, after all, traditional potatoes have a long production period and limited production, and they are simply not as good as Dutch potatoes in space.

Now, all that's needed is to plant those potatoes.

Growing potatoes is not complicated, after taking all the potatoes out of the supermarket in the space, but leaving them in a warm and bright place for a few days, the potatoes sprout.

Then Shi Yiwen chose a small plot of land in Zhuangkou as a nursery for breeding.

"Cut these sprouted potatoes into cubes, you can cut a few more pieces of large potatoes, and each piece is guaranteed to have two or three sprouts on it......"

At the edge of the nursery, Shi Yiwen instructed the village teenagers to plant potatoes.

"Rub the wound of the diced potato with plant ash, or leave it alone. Then put it in the soil about 15 centimeters apart from each other......"

When guiding them to plant potatoes, Shi Yiwen thought to himself, according to the book, the autumn potato sowing time is generally around late August to early September. For potato planting in autumn, it is necessary to ensure that there is a growth period of more than 60 days from seedling emergence to early frost...... Now, it should be about the same.

"Teacher, is the yield of these potatoes really as high as you say?"

When planting potatoes in the nursery, Xu Guangqi asked with some curiosity.

"Well, if fertilizer can be supplied, three or four thousand catties will definitely be fine, but you can't plant potatoes with human and animal manure, this kind of fertilizer will make potatoes unpalatable, but you can put some plant ash."

When it comes to fertilizer, Shi Yiwen naturally thinks of last year's Chinese cabbage.

The yield of Chinese cabbage is extremely high, and the yield of seven or eight thousand catties or even tens of thousands of catties per mu is a common thing, but because there is no fertilizer, last year's yield per mu was about four or five thousand catties, which was half of the shrinkage. There is no fertilizer, only good seeds, which do not bring the high yield you need.

Phosphate rock that has just started to be mined, perhaps, can consider setting up a fertilizer factory to turn phosphate rock into phosphate fertilizer.

Fertilizer plant!

Although ammonia fertilizer has been made from ammonia in the iron factory before, the amount of ammonia fertilizer is always limited, and the annual output is only a few hundred tons at most, and a few hundred tons of fertilizer is enough for more places? It broke through the sky of 10,000 or 20,000 mu, and if it is calculated, it is only enough to cultivate good seeds in the Zhuangzi.

However, phosphate fertilizer is different, as long as there is phosphate rock and sulfuric acid, it can be continuously produced phosphate fertilizer.

Hundreds of tons of phosphate rock are lying under the shed of the acid plant, and these phosphate rocks are mined from the Jinshan phosphate mine in Zhangjiakou.

"Is alum mountain phosphate mine easy to mine?"

As soon as they met, Shi Yiwen asked Sun Wuyue, he was originally the owner of a small coal kiln, and after selling the mine to Shi Yiwen, he also stayed in the Jingxi Road Mining Company, because he was good at mining, he was sent by Shi Yiwen to mine Jinshan phosphate mine.

"It is not difficult to mine phosphate rock, it is much easier than coal mines, basically the veins are exposed, but it is not very convenient to transport ore, as long as this problem can be solved, as far as the local phosphate rock is concerned, it is definitely no problem to produce 20 or 30 million catties of ore a year."

Twenty or thirty million catties.

That's enough for millions of acres.

Thinking so in his heart, Shi Yiwen said.

"Wait a little longer, when the fast road for transporting coal is repaired, let's repair it little by little to the side of Alum Mountain, all the way to the mouth of the phosphate mine."

Now, Shi Yiwen has been accustomed to calling the railway "fast road for transporting coal", which is the suggestion of the British public Zhang Rong, in fact, it is also a secret crossing of Chencang, the railway is too attention-grabbing, but the fast road for transporting coal is different, everyone just listens to the freshness, for the wood-paved track, but also just take a look, and then no longer curious.

But the wooden rail road is only temporary, and it will definitely be replaced by the railway in the future. Sometimes, a temporary concession is made for the sake of a longer-term goal in the future.

"That feeling is good, but I don't know, the fast road, is it really like what you said, you can pull hundreds of thousands of catties of things."

Sun Wuyue complimented.

"If you can really transport hundreds of thousands of catties of coal, then next month, the people of the capital will be blessed, after all, next month, they will almost start preparing for winter coal."

"Winter coal?"

"Yes, Childe, it is the coal used for the winter coal kang, and every household must prepare thousands of catties of coal, which is also the best time for business in the mine last year."

Sun Wuyue's words made Shi Yiwen stunned, and he immediately realized a problem - it seemed that he was not ready.

didn't even wait for Shi Yiwen and others to make a large amount of sulfuric acid, Zhang Weiliang, who rushed over from the city, interrupted his plan.

"Zhiyuan, we have to hurry up and repair the fast road from the mine to the capital!"

As soon as they met, Zhang Weiliang said in a hurry.

"Next month, the officials and people in the capital will start to prepare coal for the winter, if we can't transport enough coal to the capital, when the time comes, I'm afraid that we will drown in the impeachment of the people!"

Although he always thought that he looked down on those who only knew how to impeach others and couldn't do a little bit of business, Zhang Weiliang knew very well the "destructive power" of those people.

"Wait, what's going on with you?"

Looking at Zhang Weiliang's eagerness, Shi Yiwen muttered in his heart.

"What else could it be? Zhiyuan, do you think that no one is staring at the Jingxi Road mine now, the coal in the capital has been tight in the past few months, the price has remained high, I don't know how many pairs of eyes are staring at us, if we wait until the time to prepare for the winter coal, the coal price will not come down, and someone will definitely impeach us, and at that time, maybe the road will have to be demolished! ”

"I see who dares!"

When Shi Yiwen heard this, he immediately snorted coldly.

"I'm going to see who is so blind!"

"It's not that you don't open your eyes, those who are full of food all day long and have nothing to do, except for impeaching others, what good things have you done? When the time comes, they will blame all the charges of insufficient coal in the capital to the Jingxi Road mine! By then, it's all night! ”
