Three Kingdoms, at the beginning of the game, recognize the thief as the father, hit the spectacle,

Frowning suddenly, Zhang Yan subconsciously held his breath and tightened the mask on his face.

"Ahem, Deheng, you..."

"Ah, it's really been a long time. Have you been well recently?"

Nodding to Ma Jun in embarrassment, Zhang Yan felt the faint stench in the surrounding air, and even his breathing became a little sluggish involuntarily.

On the other side of him, Ma Jun was also a little embarrassed, obviously knowing that the smell on his body was not very pleasant at the moment.

Not only his body, but even the entire interior of the thatched hut, and even the sky above the farmland outside the hut, was filled with a faint stench.

"Thanks to the lord's love, everything is safe here in Jun."

Pursing his lips and recalling to Zhang Yan, Ma Jun was also a little embarrassed about the faint taste between the two now.

Since the beginning of July, after Zhang Yan arranged the tasks for a period of time in the future, Ma Jun hastily started his scientific research plan.

Although the topic that Zhang Yan set for him that day was a bit of a spoof, but in order to get the other party's recognition and at the same time strive to take the task of developing weapons promised by Zhang Yan into his own hands, Ma Jun did not have the slightest slack.

After the crowd dispersed that day, he immediately prepared his staff and started working with his helpers who could read and write, but were not lazy.

To put it simply, Zhang Yan only set three goals for him this time, which are to sort out and record "nitrate soil" - that is, the conditions and cycle of manure decomposing; Substance; and the separation and purification of this effective substance, from which to find the method of making fire nitrate these three points.

As long as these three points can be achieved, then Zhang Yan has admitted that he is currently capable of undertaking future weapon research work.

釺. 草: 0 Lu Ba Wu Lu [-] Wu ろ

For these three requirements, Ma Jun, who had already been familiar with the experimental method given to him by Zhang Yan, naturally knew it by heart at the first time.

First of all, the simplest one is naturally the first point, that is, how to produce nitrate in large quantities and stably.

In fact, at this point, people in the Eastern Han Dynasty had already had relevant experience, but they did not have a unified and perfect inheritance of this knowledge.

Organically decomposed and fertile fields are the means of production for farming that have been circulated among the lower-level families since the Qin Dynasty. It is naturally not difficult for Ma Jun to standardize this knowledge, and it can be said to be free. a topic of .

Ma Jun also knew that the reason why Zhang Yan took this as one of the assessment items was not to test how flexible his mind was, but to test his basic skills and patience.

There is not much innovation in this kind of sorting and induction work. As long as the rules are repeated and the experiment is repeated, the final answer can be obtained.

At least now, Ma Jun is doing this.

Ever since he left Zhang Yan that day, Ma Jun focused his energy on this for the first time.

Whether it is the decomposing of nitrate soil or the state of crop growth after fertilization, it takes a lot of time. Even if he is in a hurry, it is only today, a month later, that he has made some small achievements in this regard. results.

Just to get these results, the whole thatched hut and the vicinity of the farmland will inevitably be made a bit of a mess by Ma Jun.

Just like the stench of cow dung that is still lingering in the air...

These are all necessary sacrifices.

Sighing slightly, Ma Jun turned his attention back to Zhang Yan in front of him.

At the same time, Zhang Yan also smiled, and asked Ma Jun softly.

"It's good that everything goes well."

"It's just Deheng. A few days ago, I heard people say that you have made some progress here. I wonder how the progress of the experiment is now?"

Chapter 20 The perfect answer for this stage

To be honest, Zhang Yan was very sure of Ma Jun's ability. After all, from the very beginning, he knew that there was no significant difference in intelligence and ability between ancient people and modern people.

Although limited by technology in terms of knowledge, even if the famous Marquis of Wuxiang comes to later generations, he may not be able to learn blockchain and other related knowledge in the first place, but Zhang Yan believes that as long as they are given enough Given the time and space, these ancient people will definitely not be worse than modern people in terms of their own achievements.

What Zhang Yan didn't expect was that even though he already had [-]% expectations for Ma Jun, he still underestimated him a little bit.

……

"what?!"

"You said that you have sorted out the complete method of making nitrate soil, and also determined the maturity cycle of fertilizer?"

"You even have an idea of ​​how to make fire nitrate?"

Looking at the smug young man in front of him with some horror, Zhang Yan's expression at the moment didn't know whether to say it was excitement or surprise.

You know, this thing Zhang Yan had already prepared the psychological expectation that the other party would have to work hard for two or even three months before he could achieve any results.

But unexpectedly, in less than a month, Ma Jun actually told him that he had fumbled a lot about what Zhang Yan ordered.

Please, even crops need enough time to grow, okay?

Secretly complaining about the other party in his heart, Zhang Yan originally thought that the results that Ma Jun sent people to bring up this time were just some staged achievements, but who would have thought that the other party would tell him directly that he not only had to advance Hand in the test paper, and the test paper questions are too simple for him?

But at this moment, facing Zhang Yan, Ma Jun had also come to his senses, with a look of pride on his face.

"My lord, that is exactly the case."

……

"Details."

Instead of making useless exclamations, Zhang Yan planned to let the other party speak with facts to prove that what he said was true.

And Ma Jun also nodded, and explained to Zhang Yan what he did.

"My lord, just listen to me speak slowly."

Gently flicking his sleeves, Ma Jun's expression was full of confidence at the moment.

"My lord, you set three goals for me back then. The first one seems to be the easiest, but it is actually the most time-consuming and the one with the most workload."

"In order to achieve results as soon as possible, I did not choose the crops that were planted in the summer in recent days as the test object, but discussed with Kuai Qi and Guo Guo, and spent money to requisition the existing farmland of some self-cultivating farmers as a test object. Experimental field."

"After all, if we wait until the batch of summer crops emerge, at least another month will be wasted."

First, he briefly talked about his thoughts to Zhang Yan, and Ma Jun pointed to a large patch of scattered fields near the thatched hut, which was the land he requisitioned with money.

Since I only requisitioned this part of the field for experimentation, the ownership of these fields is still in the hands of those farmers, and the products on the farmland are still owned by the farmers.

Therefore, seeing that Ma Jun was willing to pay, and with the background of the Wancheng government office, these farmers were happy for him to make a fuss.

Opposite him, Zhang Yan also nodded slightly, as if he was quite satisfied with Ma Jun's decision.

From this point of view, Ma Jun is by no means an ordinary person who follows the scriptures. If he can skip unnecessary steps in such a place, it is obvious that the other party has understood the specific purpose of some experimental methods he gave him earlier.

Afterwards, Ma Jun continued to speak.

"...That's it. According to different mixing ratios of manure and soil, I mixed chicken and duck manure, cow and sheep manure with the loose and soft farmland soil near the Lujiang River respectively, and set up a total of ten groups of different test subjects."

"In each group of different mixing ratios, these dung soils will be decomposed in different environments for different times, forming a more detailed test group of hundreds of large and small."

"Afterwards, I will topdress the existing crops near Wancheng, which is the area where you are now, my lord. Except for about [-]% of the crops being burned to death, and nearly [-]% of the crops remain unchanged, The remaining crops were significantly different from the untreated control."

"This is the whole result of this experiment. I finally summed it up two days ago and recorded it in this file. You can take a look at it, my lord."

"Perhaps in terms of precision, there are still many things that can be improved in this experiment, or can be further improved. But in a short period of time, whether this data is used as a production and use guide for nitrate soil or as a fertilizer, Thinking about it is enough."

Introduced to Zhang Yan with an extremely proud expression, Ma Jun finally handed several densely packed papers to Zhang Yan's hands.

After Zhang Yan watched it for a while, the expression on his face became more and more surprised.

"Hehe, okay, Ma Jun."

"well done!"

Not stingy with his own praise, Zhang Yan, after looking through the test records roughly, found that Ma Jun had carefully compared the test data in various situations one by one, and at the same time came up with the results of chicken and duck droppings. The best time for decomposed manure and cattle and sheep manure.

If the time is not enough, the incompletely decomposed manure will easily cause the seedlings to burn, and if the decomposing time is too long, it will cause a very bad smell, and it is meaningless for farmers to waste time.

In those few short pages, Ma Jun has already summed up a series of conclusions.

What made Zhang Yan even more satisfied was that, in addition to these contents, Ma Jun also attached a copy of his own understanding of the experiment and his vision for the direction of the follow-up experiment at the end of the experiment record.

Just like a professor's notes on graduate students, such a small action by Ma Jun made the value of this manuscript extremely precious.

Admittedly, perhaps in terms of the precision of the experiment, there are still many things that can be improved in this experiment:

For example, should I add water when topdressing?

For example, when is the most suitable time for topdressing when the crops are growing?

For example, will the same fertilizer be used differently in different soils and different crops?

As Ma Jun said before, in these respects, there is still much room for improvement in this experimental data.

But for Zhang Yan, these are completely enough for now.

Those follow-up experiments can be handed over to other people with more ordinary qualifications, after all, they now have Ma Jun's understanding of this experiment as a guide.

The rest of the work is time-consuming and energy-consuming, requiring Zhang Yan to invest a lot of manpower for a long time to refine and perfect.

In a short period of time, this piece of data is completely enough for Zhang Yan.

This is true in every respect.

From the perspective of agricultural development, Ma Jun's move can be said to be the first systematic fertilizer production and use plan that has been sorted out. Although there are still some defects in it, it can also contribute to the grain production in the Lujiang area, and even the entire Jiangdong. bring about great progress.

According to what Zhang Yan learned, in the Eastern Han Dynasty, the limit of rice yield per mu was only about [-] to [-] Han Jin, and through reasonable planting methods, it could reach [-] Han Jin per mu at most. The limit amount of grain production in the Eastern Han Dynasty.

But in the Ming and Qing Dynasties, the limit output of rice in the south of the Yangtze River soared from [-] Han Jin to [-] Han Jin in an instant, or even higher.

You must know that there were no such things as chemical fertilizers in the Ming and Qing Dynasties. Although some data cannot represent the whole, it can also be seen that after the chaos of the Five Dynasties, especially after the collapse of the aristocratic family class and the lifting of the ban on production-related knowledge such as fertilizer use, the entire What a huge progress has been made in the grain production of the Huaxia region.

In addition, from the aspect of weapons, especially from the production of gunpowder, Ma Jun has determined the production method of "nitrate soil" in one fell swoop, that is, the production method of decomposed dung. In the future, mass production of fire nitrate and even gunpowder paved the way.

At this stage, Ma Jun can be said to have handed in a perfect answer to Zhang Yan.

Chapter 21 Establishment of Technology Division

Looking at Ma Jun in front of him with satisfaction, Zhang Yan found that the other party was no longer as white and clean as before, and looked like a frail scholar who stayed at home. After working with crops for a long time, he became a little stronger, and his skin gradually turned into a healthy bronze color.

At this moment, Ma Jun raised his head slightly, obviously appreciating Zhang Yan's praise very much, and even smiled with a hint of pride.

Watching the other party's change with some emotion, Zhang Yan contemplated for a moment, then softly rewarded the other party.

Rewards for meritorious deeds and punishments for demerits have always been Zhang Yan's fundamental attitude towards his team.

Just like when Wei Xian discovered a loophole in the construction of the large library this time, Zhang Yan rewarded a considerable amount of gold and silver. For Ma Jun who has made a lot of progress this time, Zhang Yan also plans to reward Ma Jun. .

It's just that for Ma Jun, who was born in the Fufeng family, Zhang Yan didn't intend to simply reward some money and property.
