The days passed smoothly in September, and in October, when Zhao Youqian held the newly made paper and showed it to Sun Siyuan like a treasure, Sun Siyuan finally remembered something that she had forgotten.

"Steward Zhuang, how did you inquire about the sweet potatoes I asked you to inquire about?"

Steward Zhuang blushed and didn't speak. These days, he has tried his best to let this little couple toss, where is the time to inquire about this!

"I'll ask tomorrow." The housekeeper promised. Sun Siyuan pouted: "Forget it, I'll ask by myself!" ”

After inquiring, Sun Siyuan only felt that her heart, liver, spleen, lungs and kidneys hurt. The sweet potatoes I saw in Taiping County at the beginning, planted in a pit and one by one, although the ridges are not too high, but there are also the rudiments of the earth's planting, but I didn't expect the sweet potatoes in the capital to be completely different.

She didn't know that the sweet potato planting in Taiping County was inspired by the people of Tongzhou County, and in the final analysis, it was because of her relationship. As for the sweet potato planting method of the people of Taiping County in the past, it is okay not to mention it......

The sweet potatoes in the capital have a yield of only seven or eight hundred catties per mu, Sun Siyuan silently calculated in his heart: the flour yield of sweet potatoes is about a quarter, so that there are only one or two hundred catties of flour per acre, and the world can only grind flour and make vermicelli by hand.

Thinking about the yield per mu of two or three thousand catties in the land of China, Sun Siyuan felt that she wanted to plant sweet potatoes again......

Although there is only a yield of seven or eight hundred catties per mu, sweet potatoes are already considered "high-yield" crops compared with wheat and rice, and the price is relatively cheaper, less than two pennies a catty, Sun Siyuan bought three thousand catties of sweet potatoes in one go, all piled up in the "factory" newly built by Zhao Youqian.

Three thousand catties is not much at all, but the Zhuang housekeeper is distressed to death, he thinks that Sun Siyuan is wasting money, three thousand catties of sweet potatoes, when do you have to eat them, if you can't eat them, you will have to freeze!

The factory and the soy sauce workshop are connected, and there is a large open space in the middle. Sun Siyuan built a pool on the vacant land, pulled a waterproof cloth and put it in the pool, rented a large stone mill and started construction.

The four people in the soy sauce workshop are still relatively idle, and they can be called directly, so Sun Siyuan will be a small supervisor, directing the four of them to work together with the village steward.

The large stone mill is not the household stone mill of ordinary people, it is a large stone mill rented from the big mill and pulled up by relying on four donkeys at the same time. Sun Siyuan instructed people to wash the sweet potatoes, cut them into small pieces and throw them into the stone grinding holes to grind. The ground sweet potato dregs will flow down the water, and then pour the ground slag powder into a specially customized hanging net, mixed with the water and shake slowly, the fine powder water flows into the pool, and the remaining coarse dregs are poured aside.

A few people worked hard for a day, and they got a thousand catties, and the pool was full. Sun Siyuan had no choice but to let everyone rest and continue the next day.

The next day, after a night of precipitation, the powder in the pool had sunk to the bottom, and it was full of slightly colored water.

After three or four days of busyness, he finally finished grinding all the 3,000 catties of sweet potatoes, and returned the stone mill and donkey, and Sun Siyuan began to dry noodles.

The floor is cleaned first, a layer of wheat straw is spread on the ground, and then a clean tarp is spread. Break the flour cubes in the pool, dry them on a cloth, and wait for them to dry and turn into powder.

Although everyone didn't say it, they were very surprised in their hearts, surprised how Sun Siyuan could come up with such an idea to make flour. Sun Siyuan doesn't feel much about these, she just thinks that the industry is underdeveloped, the earth's plastic cloth is cheap and easy to use, the tarpaulin bought by the world, I don't know how to do it, in fact, it is still leaking, but it is very expensive!

On three or five sunny days, the flour was dried, and Sun Siyuan carefully packed it in a large cloth bag, totaling six hundred catties, which was lower than the one-quarter powder rate expected by Sun Siyuan, plus the money for customizing hanging nets, renting and grinding money, and buying tarpaulins, the cost price of this catty of powder was more than ten yuan!

It is several times higher than the price of Huaxia that Sun Siyuan knows!

"I want to promote the correct way to grow sweet potatoes, otherwise it will be a waste of arable land!" Sun Siyuan thought in her heart. Although the world is still in a vast and sparsely populated stage, high-quality arable land is also a valuable resource, and if possible, it is naturally good to achieve maximum output.

After all, there is more food, so she can waste it casually......

Sun Siyuan patted her head, what did she think, how could she waste food? To produce more food, of course, is to create more food, improve people's lives, and by the way, reserve resources for the development of industry!

What I pursue is not only food and clothing, but also a high-quality life! Sun Siyuan is righteous in his words.

The sweet potatoes with a yield of seven or eight hundred catties per mu in the capital have met the food needs of the people in the capital, and if you want to increase grain production in the short term without affecting the price, the best way is to develop more ways to eat.

However, there are only a few hundred catties of noodles at home, and Sun Siyuan is reluctant to use them to make fans. After all, there are no tools or anything, and when the experiment is done, I am afraid that such a little flour will be finished in three or two clicks. It's powder, she once saw her mother make it, and the amount of noodles is small, so you can try it.

"By the way, Steward Zhuang, let me ask you, if I improve the way of planting sweet potatoes, can the emperor give me some rewards?" In her spare time, Sun Siyuan asked the housekeeper of Zhuang.

"Uh......" Steward Zhuang paused for a moment when he heard this, and seemed to have sorted out his thoughts. Previously, Tongzhou County promoted a new planting method, the emperor was happy, and rewarded a string of officials, if you have an idea, I can contact the emperor for you, there is no official position, and the emperor is still not short of silver and gold. ”

said so, in fact, he had already told the emperor everything about how Sun Siyuan made noodles. Don't say no, such a big posture, the secret servants have told the emperor, and he has nothing to hide. After the emperor knew about this, he sent someone from the Ministry of Industry to grind sweet potatoes in imitation of Sun Siyuan's methods, and I am afraid that the effort will be almost dry.

The planting method promoted by Tongzhou County at the beginning has also caused a lot of reaction in the capital. Now many people here plant some green millet, and a few people grow rice, all of which are Sun Siyuan's method, but people here didn't expect that sweet potatoes can also be referenced.

"Then I say, you write it and show it to the emperor, lest you have a bad memory and have something to say." Sun Siyuan took a blank booklet and gave it to Steward Zhuang and asked him to remember what he was going to say next.

Holding the booklet, Steward Zhuang smiled bitterly, his head was very flexible, how could he have a bad memory...... Oops, I forgot to tell the emperor that Zhao has money to make paper......
