In order to set an example of modern agricultural planting, Chen Xu himself also planned a full 20 acres of wheat fields on the river beach downstream of Qinghe Town as his agricultural demonstration field.

This was originally also farmland, but because of the war has been abandoned for many years, so it has long been overgrown with weeds and thorns, Chen Xu then asked Niu Dashi to hire seven or eight villagers to clear out all this piece of land, and hired two experienced old farmers to plough it out, and now a large flat wheat field has been formed, a group of students in the primary school after school every day after school task is to pick up cow dung, horse manure and even leaves piled up in the field to ferment, and for the fertility of the land, Chen Xu also dried the cut weeds and thorns and piled them up in the wheat field to burn several large piles of fire dung.

The so-called fire manure is to pile the weeds and thorns and soil layer by layer, and then ignite it to burn it slowly, and finally form a large pile of plant ash, the main component of plant ash is potassium carbonate, when the time comes to plant wheat, these plant ash and compost are evenly mixed into the soil, which will increase the fertility of the soil, of course, farmers also have their own methods, that is, burning the straw left in the ground can achieve the same purpose.

After inspecting the experimental field, several huge piles of fire dung were burning, and Niu Dashi and a few villagers were digging drainage ditches with hoes in the wheat field.

Wheat is a dryland crop, it likes to be dry and does not like waterlogging, as long as there is a very shallow moisture in the soil, it can grow well, and if there is too much water, it will not grow well, and the roots will fall when they are rotten.

And this piece of land is next to the Xiaoqing River, no matter what, it will not be too dry, so it is necessary to prepare for waterlogging in advance, this experimental field Chen Xu is ready to be completely in accordance with the planting method of later generations, deep ploughing and ploughing the ground, under the foot fertilizer, row spacing ten centimeters of sowing, and six rows of ridges, which is convenient for weeding and permeable ventilation.

Wheat Chen Xu has watched his father plant since he was a child, usually after the peanut harvest, he sows the seeds, and the sowing is done with a rake, so he remembers it very clearly.

Peanuts are not available now, and they seem to have been introduced from the Americas later.

And the rake is estimated that many people do not know, it also has a name called cocoon car, in fact, it is a seeder, a bucket above, three plough teeth below, pulled forward by people or oxen to pull forward, the plow tooth turns over the leveled soil about two inches deep, the seed falls from the small hole behind the plow tooth just falls in the soil ditch opened by the plow, there is an oblique crossbar behind the three plow teeth and pushes the turned soil back to cover the seed with the advance of the coke rake.

This process is done by ditching and sowing the soil together.

If there is no rake, this process needs three people to complete together, and only one row of sowing operations can be completed at a time, while the rake only needs one person, one ox or two people to sow three rows at the same time, so the efficiency of the harrow is more than ten times higher than that of pure labor.

The history of the columb, which is also very long in China's agricultural production, seems to have been invented in the Han Dynasty, so in Chen Xu's view, the wisdom of China's ancestors is indeed the first in the world.

The production of the rake is slightly more complicated than the curved plow, but it is not difficult to make it at all, and the sowing area can reach hundreds of acres in a day after mastering it, and the land of a family is estimated to be all done in half a day.

"Brother Xu, isn't it a bit of a waste of effort to dig so many trenches in the ground?"

Niu Dashi is shirtless, looking similar to Chen Xu, black and thin, all of them are ribs, but three meals a day in the elementary school cafeteria are full of steamed buns, so he has a good complexion, and his appearance is completely different from what Chen Xu saw when he first woke up, and he seems to have grown a lot taller.

"This is called prevention, if the rain can't be drained out suddenly, the roots will rot after a few days, so this drainage ditch must be dug well!" Chen Xu said.

I remember one year when the Xiaoqing River was flooded, the water flooded the crops on both sides, and the flood took five days before the flood receded, and then dozens of people starved to death in the town that year, and hundreds of people fled the famine and never came back, and the children starved to death even more, and one of my younger brothers and sisters starved to death that year, and the county order didn't care, miserable! It's miserable! ”

An elderly villager with sad memories on his face.

"Farming depends on the sky to eat, natural disasters and man-made disasters are unavoidable, and when the water in Xiaoqing River is small in winter, see if you can organize people to build a river embankment to fence the riverbank, then it may be much safer!" Chen Xu sighed and said.

"Lord Lidian rest assured, as long as you speak, when the time comes, we in Qinghe Town, regardless of men, women and children, will be happy, the matter of repairing the river embankment has been mentioned to Lao Lidian many times before, but he refused, now with Lord Lidian, we Qinghe Town is going to enjoy happiness!" Several villagers digging trenches were excited.

"Okay, the main thing now is the autumn grain harvest and then the sowing of winter wheat, so this matter can be delayed for a while, you can continue to dig a ditch in this way, and the soil will be turned up to form a ridge, which also has the effect of retaining water!" Chen Xu waved his hand and said.

"Lidian, I heard Dashi say that your experimental field may have six or seven stones per mu by then, is it true?" A villager asked excitedly.

"It stands to reason that there is no problem, but it depends on the weather and seeds, even if it can't be reached next year, as long as you continue to cultivate like this, you will definitely be able to achieve it in three or five years, so don't be lazy!" Chen Xu said with a smile.

"Don't worry, we will definitely not be lazy, this experimental field will definitely help you grow four or five stones of grain next year!" Several peasants hurriedly agreed.

"Ridian, Ridian!" A small child came running from a distance.

"What's the matter?" Chen Xu asked loudly.

"Go to the elementary school, the prefectural magistrate is here!" The child was panting and yelling.

This is for no reason, what is Jiangbei Pavilion doing in Qinghe Town?

Although Chen Xu was inexplicable, he still told Niu Dashi and a few villagers a few words, and then hurriedly followed the children to the elementary school.

When he arrived at the elementary school, he saw Jiang Beiting already sitting in the primary school cafeteria drinking tea, chatting with two old men, and his son Jiang Chuxing and daughter Jiang Chuyue were sitting next to him, and several soldiers were standing outside the classroom watching the class.

"Chen Xu has seen Master Jiang!" Chen Xu hurriedly walked over and saluted, and greeted Jiang Chuxing and Jiang Chuyue slightly.

"Nephew, I've been waiting for you in the county for so long, and you haven't visited you, do you have an opinion about me?" Jiang Beiting said very politely.

"Uh, that...... Lord Prefectural, I've been busy lately, and there are too many things to do! Please forgive your sins. Chen Xu had no choice but to smile dryly and apologize.

"Hmph, it's the farming season now, where will you be busy, I think you deliberately shirk and don't want to see me!" Jiangbei Pavilion obviously has a lot of opinions about Chen Xu's release of his pigeons, after the last time he suppressed the bandits, he invited Chen Xu to go to the county seat to play with his daughter, but Chen Xu didn't have any birds at all, and he was making wine and repairing the health center, and he had to supervise the cultivation of the fields, and he was a busy mess every day, not to mention that the water was gentle these days, and he completely forgot about it.

Let alone...... Chen Xu glanced at Jiang Chuyue, who was looking around, and couldn't help but twitch a few times with his face, this brutal and willful little girl was really not his favorite dish, hugging her legs and eating stuffed teeth, compared to the gentleness of water, it was simply incomparable, and it felt like it was in the way when serving tea and quilts.

"What do you think I'm doing?"

Sure enough, Jiang Chuyue instantly keenly felt Chen Xu's disgusted eyes, so she immediately stiffened her sentence and rolled her eyes vigorously.

"The third sister must not be rude!" Jiang Chuxing hurriedly whispered.

"Alas," Jiang Beiting sighed leisurely, put down the teacup and said, "You all leave for the time being, I have something to say to Chen Lidian!" ”

"Third sister, let's go, let's go to see the master in elementary school!" Jiang Chuxing stood up and pulled Jiang Chuyue away, and the two old men who were chatting with him also stood up and said goodbye, and then only Chen Xu and Jiang Beiting were left in the pergola.

"What do you have to say about the county commander, Xu Xi's ears are listening!" Chen Xu felt a trace of seriousness from Jiang Beiting's face, so his face calmed down.

"The last incident has already had a result, and Zhao Zhe has also been sent back to Xianyang by the county guard, so don't worry about that incident in the future!" Jiang Beiting stroked his beard and said.

"That's good, that's good." Chen Xu breathed a sigh of relief, although it has been a month since Zhao Zhe colluded with the mountain bandits to rob the summer grain tax, but it has always been like a boulder that weighs him down, mainly because Zhao Zhe's father's identity is too scary, and he castrated his son, this kind of hatred of cutting off children and grandchildren will definitely not be as easy as Jiang Beiting said.

I'm afraid this matter is only temporarily suppressed, then Zhao Gao has a grudge, maybe one day he will be trampled to death by him if he is not careful, for his own safety, it is better to inquire about the Tao inside, so Chen Xu arched his hand and said: "Lord County Commander, can Xu ask the specific experience!" ”

Jiang Beiting looked at Chen Xu with a pair of eyes and said, "Someone assassinated Zhao Gao on the street in Xianyang!" ”

"What?" Chen Xu shook his hand, the teacup fell to the table with a click, splashing his face with tea, and he was stunned for a long time before he wiped his face clean with his sleeve and helped the teacup up.

"Does the nephew know the inside story?" Jiangbei Pavilion said playfully.

"Hehe, how is it possible, I have been staying in Qinghe Town, how can I know about Xianyang and Spicy Away!" Chen Xu laughed a few times to cover up.

"Last time, I remembered that you had an entourage dressed in black, with superb swordsmanship, and made great contributions in the extermination of mountain bandits, then Zhao Zhe was injured in his hands, and I also heard that the person who assassinated Zhao Gao was also a man in black with vigorous skills, holding a black iron sword, how can it look seven or eight points similar to your entourage!" Jiang Beiting said expressionlessly.

"Ga" Chen Xu's hand shook again, and the teacup he had just picked up rolled to Jiangbei Pavilion with a gurgling roll.
