The regent wants soil pesticides.

The news about the fertilizer quickly spread among the nearby tenants. Although the Liu family's wife could not avoid being called a "bold lady" by Liu Dalang, Liu Dalang went to register to receive the fertilizer.

First of all, he was the first person to see the effect of the fertilizer, and he still has some confidence in the fertilizer. Based on his experience, the harvest is not bad, it is only five catties of grain. If the harvest is good, it will be more than ten per mu Jin is no problem.

Secondly, his own mother-in-law had begged before the regent, and the prince knew about their family.

If he doesn't support the prince with some fertilizer on credit, what if the prince gives them small shoes to wear?Even if the princes and nobles forget things a lot, they can't help but there are so many "kids" underneath.

After that, several companies came to buy fertilizer on credit. Wang Xing handed over all the fertilizer related matters to his godson Wang Hu. He saw from the fertilizer that there would be great profits in the future, so naturally he had to be close to his own people first, and then He himself, as long as he serves the prince well, then he can say anything.

Yan Yunhe took Wang Hu and taught him how to fertilize, and then asked him to teach those tenants that it was a matter of harvest, and Wang Hu also knew that he should not be careless.

If the result is not satisfactory and he finds that the problem lies with him, then he can only pack up and go back to his hometown.

Time passed day by day, and Yan Yunhe looked at the update system again, only to find that the popularity value had accumulated to [-]. These days, some readers have left, and some readers have also come. Interestingly, there are still people who give friendly reminders below, like to read From which chapter to start looking at farming.

When browsing the seed store, Yan Yunhe thought of a question, if he could always produce some seeds that did not exist in the local area, how would he explain it to the people around him?It can't be old farmers who take the initiative to contribute every time.

He thought for a moment, and wrote a letter to Shi Zhong Baidao, the right chief of the palace. There was only one main content, he wanted to let the world know that he was buying good seeds with a lot of money.

No matter it is novel or common, as long as the palace accepts it, it can get gold and silver from the palace.

Although it can't cover up everything, if he redeems some seeds from the seed store, it can be regarded as a statement.

Yanyunhe has been immersed in the fields for the past few days, and found that the farming level of the Dazheng Dynasty is really not that good.

Although it is advanced compared with other places in the same period, it has more shortcomings, and it is the average level of ancient times.

For this fictional dynasty, Yan Yunhe also found that it is a hodgepodge of ancient times. It is difficult to tell which period of history it is in just from the clothes, but it is more like the costumes in some ancient idol dramas.

From a cultural point of view, it has four books and five classics, and Yanyunhe has heard all kinds of idioms and allusions. It is not an exaggeration to say that it was in the Qing Dynasty, which also caused the historical confusion of Yanyunhe, and it is partial Very serious, there are not many agricultural books.

At this time, Yan Yunhe put down the writing brush in his hand, and turned his wrist. Compared with pen and ink, he felt that pencils were more convenient. When traveling in the past few days, it was really inconvenient to use a writing brush to record the growth status of plants.

He thought for a moment, and thought that if he wanted to do a good job, he must first sharpen his tools, and added a sentence at the end of his letter to Zhong Baidao: "Also, the workers in the mansion and the good doctors will come to Wangzhuang."

The letter was quickly sent to the palace, and Yan Yunhe looked at several pesticide formulas provided by the sister of the Agricultural University. Dazheng's current level of chemical pesticides is still far behind. It is prepared from various poisonous plants and some minerals.

That day, Yanyunhe found larvae suspected to be red spiders in the field, which is a common pest in millet. Considering the current season and the current level of productivity, Yanyunhe set his sights on the plant "calamus".

During the May Festival, the folks often use calamus and mugwort leaves to dispel filth and ward off evil spirits. This kind of plant is widely distributed and common.

Compared with the low cost of acquisition, it can prevent and control pests such as red spiders, which is a good choice for ordinary people.

Limited by the level of knowledge in ancient times, most people don't know the usage of calamus. Now that May is approaching, Yanyunhe intends to promote this kind of soil pesticide in Wangzhuang.

So, the next day, when Wang Fuzheng came, the first order he received was to make watering cans.

This is very simple to make, and there is no need for craftsmen to do it, he just needs to hand it over to the craftsman, but another request of the prince requires repeated experiments.

Pencil leads are made of graphite and clay, both of which are readily available and save a lot of work.

For the method of making the pencil lead, Yan Yunhe really tried all kinds of methods to communicate with the girl from the Agricultural University.

For example, talking about pencils from time to time, and writing the word "pencil" on paper, finally made him say "pencil" in the latest chapter.

The school girl is naturally a good helper, and she left a message on the same day about the method of making the pencil. Of course, the method has been developed. Under the current conditions, it is still necessary to continue to experiment to get the finished product. Today's simple conditions, he will not make more requirements, and can be fluent Just write.

Graphite is ground into powder by mixing water and oil, lacking industrial methods, everything can only be solved by manpower, but fortunately this experiment is only a small amount, Yan Yunhe carefully watched every step to minimize mistakes.

After two experiments, the ratio of water to oil was confirmed. The next step is to dry. There is a porcelain burning workshop in the south of Wangzhuang. The owner is considering changing hands. Considering that it will be fired later, Yanyunhe directly bought the porcelain burning workshop. down.

The porcelain-burning craftsmen also changed their employers, and now they watch the Yanyun River burn pencil leads all day long, thinking about seeing the prince's jokes every day.

Yan Yunhe was dressed in coarse linen and was mixed among the craftsmen. He was looking at the dried graphite, the fine, shiny black powder, and felt that it should be usable.

The next step is to mix it with clay and water. Speed, pressure, temperature and humidity will all affect the quality of the refill. To solve the pressure problem, they first smashed it with a hammer. Later, Yanyunhe saw a screw press in the comment area. The principle is similar to turning a screw, which is why there is a simple pressure device.

So in the experiments again and again, the time also entered May, Yan Yunhe looked at the material being pressed into the cylindrical mold, and finally exhaled.

The next step is to keep it moist and set for a week. Just in time, calamus can be collected.

Leaving Gong Zheng and the craftsman here to study the pencil shaft, Yan Yunhe got into the carriage again, and this time he finally took off his cloak.

This original porcelain workshop has actually left the scope of Wangzhuang. On the way back, Yanyun River also saw some pedestrians. At this time, most of the people passing by were businessmen. There was a group of merchants in front of their carriages. The caravan consisted of four people. Five cars full of boxes.

When going out, Yan Yunhe purposely chose an ordinary carriage, which could not be seen from the outside as the carriage of the palace, and it drove smoothly on the road without disturbing the people at all.

As for him himself, for the convenience of movement, all clothes are mainly for convenience, and he doesn't have a single jade ornament on his body. Looking at him, he can only make people think that he is a beautiful rich man.

When Yan Yunhe was looking outside through the car window, the carriage stopped suddenly, and after a while, guards came to report that the rope of the carriage in front was loose and the goods fell, and the road here was narrow, so this Then blocked the road.

Naturally, Yan Yunhe was not in a hurry, he was feeling bored while sitting in the carriage, so he got out of the carriage, and saw that the boxes containing the goods were broken, and what looked like tea leaves inside were scattered all over the place, so he told several guards Said: "Go and help, I can just keep two people here."

The guards took orders, and Yanyunhe walked to the side of the road to look into the distance, and saw green mountains and white clouds in the distance, and occasionally birds flew by. After a few days of fatigue, I couldn't help stretching.

At this time, the two guards around him suddenly became vigilant, Yan Yunhe turned his head to look, only to find that there were a few black spots approaching in the distance, and he heard the sound of horseshoes in a short while.

It wasn't until they arrived in front of him that Yan Yunhe realized that these people were riding good horses, each of them was fat and strong.

There were seven people in this group, they seemed to have put some effort into their bodies, seeing that the front was blocked, they all got off their horses at this moment, two people stepped forward to inquire about the situation.

One person found Yanyunhe and the guards standing on the side of the road, walked towards them, bowed to the obviously different Yanyunhe and said, "I have met you, sir, we are travelers returning to Luo City, you may need us." help."

Yan Yunhe smiled at them and said: "You two have misunderstood, it is not my family's goods, we are also blocked, we are just waiting here."

The obviously older of the two said quickly: "It turned out to be a misunderstanding, please don't blame me, my lord."

"It's nothing." Yan Yunhe saw their dusty appearance, curious in his heart, and asked, "Where did you come from?"

"We came from the south, and this time we are going home."

"Is it Jiangnan?" Jiangnan was rich and prosperous, and everyone loved Jiangnan at that time. When you first heard about the south, it was hard for Yanyun River not to think of Jiangnan.

Unexpectedly, the man said: "We are from Zezhou."

Yan Yunhe became energetic when he heard it. He looked at the map and knew that it was equivalent to Jiangxi and Hunan. Luocheng is in Zhongzhou, which is the Central Plains area. Many plants need to be planted in the south. He has long wanted to know what the south here is. What a weather.

"I haven't been to Zezhou yet, so I'm very curious about it. What kind of crops do people mainly grow there?"

He opened his Ruifeng eyes slightly, the eyes were full of interest, making his eyes seem to be shining slightly, and even less sick.

His appearance and demeanor were already outstanding, but at this moment, making such an expression to someone made it even more unbearable to refuse, so he easily chatted with that person.

From the main crops in Zezhou to their farming methods, whether the crops are harvested twice a year or once a year, what the locals eat, and what plants are not found in Zhongzhou, etc., the Yanyun River has more to say. I wish I could go to Zezhou to see it right away.

Although the other party could not answer every question, Yan Yunhe was able to confirm from the conversation that the climate of Zezhou in the Great Zheng Dynasty was indeed comparable to that of modern southern China.

While they were chatting, the other five people in the group also came over with their horses, and they were not very close, only separated by a relatively comfortable distance for both parties.

This is a very measured performance, if it weren't for the fact that the eyes of one of them were too straightforward, Yan Yunhe would have believed that this was a group of dutiful and polite people.
