Wannian County Ya is located in the southeasternmost corner of Xuanyangfang, and Yin Qingfeng came here for several purposes: one is to replace the little girl's cheap status with a good one; the second is to sign the six people who have no household registration as lowly registration; the third is to change the name of the deed of the house in Shengping Fang; The fourth is to apply for the house in Shengpingfang to be enclosed into an area.

came out of the Wannian County Ya, and went to the Chang'an County Ya again.

When they arrived at the county office, Ren Daliu knew that the Ren Niangzi they respected on weekdays turned out to be a lowly person.

After coming out of the county office, Yin Qingfeng was also happy for a long time, this is a 600-square-meter shop bought in the CBD of Chang'an City, and it is only 2,100 yuan, what is the difference between this and picking up rags?

The cost of changing a lowly status to a good one is three times the price of buying a slave, and as for the cost of Ren's six people falling into a lowly status, it is less than half of the cost of the little girl.

As for the price of those houses, Yin Qingfeng was taken aback: three hundred and twenty times!

Fortunately, Yin Qingfeng remembered the information he had read before, so he stabilized his mind. He remembered that the document recorded that during the reign of Xuanzong in the heyday of the Tang Dynasty, due to the abundance of people in Chang'an, the inscription on the auction of state-owned real estate by the imperial court at that time recorded: A large villa covering an area of 1,700 square meters only needs 138 guan.

The houses in Shengpingfang are just ordinary houses, although the area is more than 120,000 square meters, but the price is the price of rotten vegetables for Yin Qingfeng.

After the little girl walked out of the county office, she hugged Yin Qingfeng and cried bitterly. Now she is not only no longer a lowly person, but also the owner of Ren Daliu and that house and shop.

After the six people arranged those future workers and salesmen safely, Yin Qingfeng was about to start the next move.

This action was carried out at the food farm outside the city of Duvovina. Originally, the food town he named King Wu was on the north bank of the Wei River, but now it has been changed to the north of the avenue leading from Chang'an to Tongguan in the east of the city, between Chanshui and Bashui. The number of food towns has also dropped from 10,000 to 3,000.

The reason why he didn't dare to pack a ticket for Li Shimin at the beginning was because Yin Qingfeng was not sure if he could increase grain production.

To increase grain production, according to Yin Qingfeng's understanding, it can be roughly divided into four factors: seeds, agricultural tools, fertilizers, and cultivation technology.

The improvement of seeds requires professional technology and long-term cultivation, and this Yin Qingfeng has no way.

As for the other three aspects, Yin Qingfeng, who grew up in the city, can only try to do it.

"Little Du Bing, I've seen Lang Jun and the little lady." A man about forty years old introduced himself to Yin Qingfeng, and at the same time introduced the situation of Zhuangzi: this farm is 44,000 mu in size and has 16,000 tenants.

One mu in the Tang Dynasty was about 540 square meters, so if you count it, these more than 40,000 mu is not much, "How many people can go to the field to cultivate?" ”

"Six thousand three hundred and thirty-eight men between the ages of fourteen and fifty."

Yin Qingfeng calculated in his heart that the average person cultivates a little more than five acres, which is really not high.

"Find out all the farm tools and show me."

"Yes, please Lang Jun and the little lady come to the courtyard with the little one."

Waiting for Du Bing to bring those farm tools, Yin Qingfeng took a look, good guy: except for the sickle and plowshare are iron, the rest are wooden. It seems that the wars of the previous years were quite destructive. The farms of the Guogong Mansion all use wooden tools, but what about the common people? You don't have to think about it to know.

Yin Qingfeng has seen the real thing, and he has also learned about the Quyuan plow and other tools, and with these agricultural tools in front of him, there is too much room for improvement. So he went back into the house and drew what he knew.

The harrow plough is divided into three-toothed, five-toothed and nine-toothed plows; Pickaxes, hoes, shovels, shovels, and the highlight is the quyuan plow.

The components of the curved plough and the straight plough are only the same as the plough bed, and the plough wheel and plough tip should be bent, and a forehead, pressure plough and plow wall are added.

The advantage of the curve is that the force point of the oxen, horse or person pulling the plough in front of it is the center of gravity, which should be moved down. In this way, it is not only labor-saving, but also more flexible in turning, and the most important thing is that it can be deeply cultivated.

The advantage of deep ploughing is that deep ploughing plots are all over the place, saving effort, and not being sluggish; The roots of the deeply cultivated plants are deeply rooted and the wind is strong; Heavy rain seeps quickly in the deep ploughing plot, and the ditch does not form runoff; The water retention capacity of the deep ploughing plots has been enhanced, and the drought resistance has also been enhanced. When the plot is deeply cultivated, the top dressing and sealing of the land are returned to the pear soil; High yield. Another advantage is that deep tillage does not disturb the soil layer, protects the topsoil, and can increase the thickness of the tillage layer and accelerate the maturation of the sub-cultivated layer soil. In the application of agricultural fertilizer, it can effectively improve soil fertility.

Let Du Bing call the carpenter and blacksmith and tell them how to make it, and Yin Qingfeng went back with Yuemei.

Before leaving, he instructed Du Bing to wait for the Quyuan plough and those iron farming tools to be built and inform him, and he would come to see it again when the time came.

Two days later, in the afternoon, Yin Qingfeng took the little girl to the farm again. Du Bing took the master and servant to the field outside the village, where there were already tenants waiting.

Yin Qingfeng saw that everything was ready, so he ordered: "Let's start!" ”

When the tenants heard the order, they began to move.

In order to test the advanced nature of the curved plow, the tenants were divided into two groups: one group of curved wheels and one group of straight wheels.

When both groups returned, the advantages of Quyuan were too obvious: fast, labor-saving, and deep.

The land in Guanzhong has been cultivated by the ancestors for thousands of years, and the land is no longer very fertile.

Under Yin Qingfeng's inquiry, I learned that the people of the Tang Dynasty had not consciously or used manure on a large scale to fertilize the fields.

"Steward Du, do you know how to deal with the night incense in Chang'an City?"

"As far as the little ones know, they usually fall into the ditch in front of their respective doors."

Hearing his answer, Yin Qingfeng was a chill.

Needless to say, rich families have wells in their own homes. As for ordinary people, it is estimated that the water and the night incense are in the same canal. No wonder these ancients lived a short life, and it was difficult to live for two more years with such sanitary conditions and dietary conditions. And the longevity recorded in history is either rich or wild in the mountains, in short, there are almost no poor people in the cities.

"You organize people, go to the city every day to collect night incense and come back, and after a while, I will draw you the picture of the car containing night incense, and you ask the carpenter to make it quickly."

"What does Xiao Langjun mean by this?"

"Pour the collected night incense into a deep pit that has been dug, and then pour in some raw soil and stir it. The stirred manure is dispersed into the field to dry. Wait until a few days later when the spring ploughing is plowed, and plough directly and evenly. In this way, the fertility of the land will be greatly increased, and with the new farming tools I gave you a few days ago, the yield will be at least doubled this year. ”

"Lang... Jun, is that really the case? After listening to the last sentence, Du Bing was a little excited.

"Whether it will be like this, you will know when the harvest comes." Yin Qingfeng began to load again, "In order to facilitate transportation, those manure pits are scattered in the fields on average of fifty acres; You go to Wannian County and the county government of Chang'an County to sign an agreement to collect night incense for a long time, and we only collect the night incense in Chang'an.

By the time of this year's harvest, the yield of this farm has come up, and we will publicize it with great fanfare. At that time, other farmers will definitely be red-eyed, what should they do? Let's buy our manure directly. Think about how many night incense can be provided to us in Chang'an City every day? Think about how much land there is around? That's a lot of money. ”

"This... This is really..."Du Bing was a little confused with excitement.

"Well, whether it can increase production and make money will be discussed later. Tell me how many cattle there are in the farm? ”

It took him a while to recover, "There are nine males and females. ”

"Only nine heads? How is this enough? ”

"And thirty horses."

"That is, more than 30 heads of livestock and more than 6,000 people cultivate so much land?"

"Yes."

"How much grain does this farm produce in a year?"

"It can produce more than 350,000 stones."

"Three hundred and fifty thousand stones... An average acre is less than a stone? How much money is 350,000 stones? Faint! Yin Qingfeng finally knew why the ancients kept buying land. With this mu of income, it is not possible to buy more land.

Yin Qingfeng silently circled around the field, and he found that there were many problems.

"Steward Du, from today onwards, except for blacksmiths and carpenters, all people, including women and children, have organized themselves to dig ditches, so that they can get water to water their fields in normal times, ensure production in times of drought, and drain water in times of flooding. In addition, dig a deep well every fifty to one hundred acres. Coupled with the night fragrance fertile fields, if you do it all, I dare to guarantee that these lands will harvest no less than one million stone per year? ”

"Million stones? Million stones? Du Bing exclaimed.

"A lot?"

"Very, very, a lot~~" He swallowed.

"As long as you can do what I say, when this year's harvest comes, I invite His Royal Highness King Qin to come over and witness your merits together, how about it?"

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

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

"The small, the small must be done, please let it go, rest assured!" Du Bing was still a little skeptical.

"But you can't all grow wheat on these fields, just plant 10,000 acres. I planted soybeans, mung beans and garlic for the rest. ”

"Yes!"

"Okay, that's it, you just know what to do. Now you lead the cow here. "Just now, Yin Qingfeng found that there was no ring on the cow's nose.

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

"Xiao Langjun, do you really want to fight?" The servant who was called looked at Yin Qingfeng, and Du Bing asked Yin Qingfeng uncertainly.

Until the Song Dynasty, all cultivated cattle were not allowed to be injured, killed, or slaughtered, otherwise, you would wait to go to jail and be fined. Whoever has beef on the table can only die of illness and old age.

Now I heard Yin Qingfeng say that he wanted to stun the cow in front of him, who would dare to do it.

At Yin Qingfeng's insistence, he finally reluctantly came out and knocked the cow down. The man looked at the fallen ox and almost didn't throw away the stick in his hand, and the others also had worried expressions.

Yin Qingfeng didn't care what these people thought in their hearts, and instructed people to pass the red-hot iron bar through the nostrils of the ox and bend it into a circle, and then let people sprinkle salt water on both sides of the nostrils.

Everyone was somewhat relieved to see the ploughing ox twitch a few times in pain, indicating that it was not dead.

"After three or four days, the wound will basically heal, and you can find a rope to tie it, and the cow will be obedient." Seeing that they were still frightened, Yin Qingfeng felt that there was nothing to explain, everything depends on the effect.
