Wannian County Government is located in the southeastern corner of Xuanyangfang.

When Yin Qingfeng came here, one was to change the little girl's low-class family name to a good family name; the second was to sign the six Ren Da who had no household registration as a low-class family name; the third was to change the house in Shengpingfang to a deed; the fourth was to apply to circle the house in Shengpingfang into an area.

After leaving Wannian County Government, he went to Chang'an County Government Government again.

After the little girl walked out of the county government, she hugged Yin Qingfeng and started crying. Now she is not only no longer a cheap man, but also a big six and the owner of the house and shop.

At this time, Ren Dali and the six others looked at each other secretly. It turned out that their respected Madam Ren was actually a naughty person. At the same time, while shocked, he was also happy for themselves.

They all came from poor families and knew what the status of a slave in this era meant. Since Yin Langjun could let Madam Ren be free, what about them? Even if they didn't let him go, and with such a kind and righteous master, would they be afraid that there would be no good future in the future?

After Ren Daliu arranged the future workers, salesmen and others safely, Yin Qingfeng was about to start the next move. This move was carried out on the fief farm outside Du Fuweina City.

I didn't dare to make a promise to Li Shimin at the beginning because Yin Qingfeng was not sure whether he could increase his grain output.

To improve grain yield per mu, Yin Qingfeng's understanding is roughly divided into five factors: seeds, agricultural tools, fertilizers, planting techniques and methods.

The improvement of seeds requires professional technology and long-term cultivation, which cannot be solved in the short term.

As for the other four aspects, farmers in each era have achieved the ultimate they can achieve. After all, for most agricultural families, this is their only source of life.

Take "Qimin Yaoshu" as an example.

It records the use of fertilizers, as well as various technical knowledge and applications such as forestry, animal husbandry, and fishing.

Li Tang is now in the post-war reconstruction stage, and the yield per mu of grain may not be high, but Yin Qingfeng cannot fool Li Shimin with the experience summarized by his predecessors.

If he wants to impress Li Shimin, he has to come up with more innovative ways.

"Little Du Bing, I have met the husband and the little lady." A man in his forties welcomed Yin Qingfeng and Yuemei outside the farm.

When Du Fuwei was named King of Wu, his fief was on the north bank of the Wei River. After being demoted to Duke of the Kingdom, his fief was changed to the area north of the Bronze River Bridge and north of the Tongren Origin.

The population of fiefs was reduced from 10,000 households to 3,000 households, with a total of 400,000 mu of fiefs and employed land.

Yin Qingfeng was very happy when he first heard that there was such a big place. But after careful calculation, he found that Xiao Du Tong’s shoes were cheated.

One acre in the Tang Dynasty was about 580 square meters, and these 400,000 acres were equivalent to more than 340,000 acres in modern times. But this is not the key.

The key is that if these three thousand households are ordinary people, they should be given 600,000 mu of land in each household, based on two adult men.

But that's fine. If Du Fuwei really gives 800,000 mu of acres or 1 million mu, maybe Du Fuwei will be taken to behead one day.

From the art of management, sometimes the more polite the superiors are to their subordinates, the worse things are.

Yin Qingfeng asked, "How many people can go to the fields to farm?"

While secretly observing the two young girls, Du Bing replied: "There are 7,338 males aged 14 to 50, and about 4,200 strong women."

"Find out all the farm tools and let me see."

"Yes, please come to the yard with the youngest."

When Du Bing asked someone to bring the farm tools, Yin Qingfeng looked at it and thought to himself: "It's true! Except for the sickle and plowshare, the rest are made of wooden. It seems that the destructiveness of the war before was quite serious.

The farms in the Duke’s Mansion all use wooden tools, so what about ordinary people? You don’t have to think about it.”

Yin Qingfeng looked at the wood all over the ground for a while and then asked Du Bing to find a pen and paper. In addition to changing the farm tools to iron, the change that Yin Qingfeng could make was the curved plow.

The components of the curved plow and the straight plow are the same as the plow bed. The plow shaft and plow tip should be bent, and a bulge, pressure plow and plow wall should be added.

The advantage of the curved shaft is that the force point of the ox, horse or person leading the plow in front is that the center of gravity, which must be moved downward. This not only saves effort but also makes the turn more flexible, but the most important thing is that it can be deeply plowed.

After the painting was finished, Yin Qingfeng looked up and ordered Du Bing: "Come the carpenter and the blacksmith, and make these..."

He gave Du Bing another order and agreed to come and inspect the results three days later.

When Yin Qingfeng and the little girl came to the farm again, Du Bing and his master and servant came to the land outside the farm, where there were already tenants waiting.

Seeing that everything was ready, Yin Qingfeng ordered, "Let's start!"

In order to test the advanced nature of the curved shaft plow, the tenants were divided into two groups: one set of curved shafts and the other set of straight shafts.

After both groups of people came back, Quyuan's advantages were self-evident. The tenants happily circled around Quyuan plow several times before thinking about bowing to Yin Qingfeng.

During the Qin and Han dynasties, ancestors had already summarized a series of fertilization techniques such as base fertilizer, planting fertilizer, and top dressing. However, the fertilizers were mainly manure and urine from humans and animals.

The nitrogen content and fertility of manure are relatively high, but the fertilizer speed is relatively fast. It is suitable to make base fertilizer and top dressing. Just pay attention to preventing seedlings when using it.

In contrast, the nutrients of compost are relatively balanced, and the ratio of nitrogen to carbon is more reasonable. It is also conducive to promoting the formation of soil solid particle structure, increasing the soil's ability to retain water, heat, breathable and fertilizer, and is more suitable for use as base fertilizer.

Yin Qingfeng also has another choice for the use of fertilizer: green manure. However, green manure and compost both require time to ferment, and spring plowing will be carried out at the end of the first lunar month. Therefore, he only asked Du Bing to collect a large amount of toilet fertilizer and manure last time.

Looking at the tenants who were turning the ground, Yin Qingfeng thought of a question, "How many livestock are there in the farm now?"

"The male and female are nine cows in total, and there are thirty horses."

Yin Qingfeng said slightly surprised: "That is to say, more than 30 livestock and more than 10,000 people cultivate so much land?"

Du Bing looked cautious, "Yes." He looked like he was afraid that Yin Qingfeng would be angry and fell from the sky.

Yin Qingfeng calmed down, "Then, how much grain can this farm produce in a year?"

Hearing this question, Du Bing proudly replied: "From years of experience, it can produce about 390,000 stones of grain here."

"390,000 stones... On average, one acre is less than one stone? How many 390,000 stones are only a few stagnants? I'm so dizzy!" Yin Qingfeng finally knew why the ancients kept buying land. With this yield of acre, it would be impossible not to buy more land.

Yin Qingfeng shook his head helplessly, and then stood there silently.

After a long time, Yin Qingfeng ordered: "From today, except for the blacksmiths and carpenters, all the people, including women and children, will organize to dig ditches. Dig a deep well and a cesspool every fifty acres.

If you did it all, can I guarantee that these lands will harvest no less than one million stones per year?”

"Million stones? Million stones?" Du Bing screamed in surprise.

Yin Qingfeng asked relaxedly: "Are there many?"

"Very, very, very much~~" Du Bing swallowed.

"As long as you can do what I said, when you get this year, I will invite His Highness the King of Qin to come over and witness your contributions together. How about it?"

"Qin...Qin...Qin...Qin King?" Du Bing was shocked again.

"That's right, whether you can add glory to the Duke of Wu's mansion depends on how you do it."

"Young man, you must do your best. Please don't worry!" Du Bing was still a little skeptical.

"But you can't plant millet all of these lands, just plant 10,000 mu. Plant 200,000 mu of wheat, and the rest, beans, beans and garlic, beans and garlic for me, except for the necessary vegetables."

Du Bing hesitated and said "yes" and did not dare to speak too much. During these two dealings, he deeply felt that this young boy was definitely not the legendary playboy in the deep house.

Not only was he the philosopher of the head of the family, he also seemed to know the King of Qin. With this point, he did not dare to question any of the boy's decisions.

Since ancient times, farmers have used millet to pay taxes.

But for Yin Qingfeng, although millet produces similar per mu to wheat, it is good to use it for porridge. Without rice, eating noodles is more suitable for your appetite.

"The planting matter has come to this point, just be sure of it. Now you take the lead in the cow." Yin Qingfeng just found that there was no ring on the cow's nose.

After asking clearly that there were ready-made iron bars in the village, Yin Qingfeng made people knock the cow unconscious.

The tenant who was called looked at Yin Qingfeng and looked at Du Bing again. Du Bing had no choice but to nod helplessly.

Since ancient times, it has been stipulated that all plowing oxen are not allowed to be injured, beaten to death or slaughter. Otherwise, you should be fined if you have beef on the dining table. It can only be killed by illness or old age.

Now, after Yin Qingfeng said he wanted to knock out the cow in front of him, who dared to attack?

Under Yin Qingfeng's insistence, he finally barely came out to knock down the cow. The man looked at the plowing cow that fell to the ground and almost threw away the wooden stick in his hand, and the others also had a nervous expression.

Yin Qingfeng ignored what these people were thinking and directed the people to pass the red-hot iron bars through the nostrils of the cow and then bend them into a circle, and then let someone sprinkle salt water on both sides of the nostrils.

Everyone saw the plowing cow twitching in pain a few times, indicating that it was not dead yet, so they felt a little relieved.

"After three or four days, the wound will basically heal. If you find a rope to tie it up, the cow will be obedient."

Seeing their terrified look, Yin Qingfeng felt that there was nothing to explain, it depends on the effect.
