Chapter 12 Chapter 12 Fertilizer Experiment

Thanks to Tolin Si, this year is the most fruitful autumn harvest, everyone in Li County thinks so.

The harvest was good, and there was surplus grain after paying taxes. Even the usually deserted market was filled with the atmosphere of trade.

However, recently there have been people buying wild rabbits hunted near the mountains and forests, which makes people feel a little strange.

In the past, wild products like hares would be put on display for a long time without anyone interested in buying them. After all, they were not cheap, and there was not much rabbit meat. It would be better to go to the butcher shop and buy some pork with the money.

However, this little episode was soon diluted by the joy of the harvest and forgotten by the people.

After the autumn harvest, the weather gradually turned cooler, and spring was waiting for Lin Si to wash up.

Since Lin Si came to Li County, she only wears a headband as a daily hair accessory, and her gold and silver jewelry has been left gathering dust.

There is no way to avoid the spring, so you can only choose headbands of different colors every day, or match two or three headbands of the same color.

Chunyi expressed her helplessness about this, as she discovered that her own county lady was a "lazy person".

For example, if you find a hairband convenient after using it once, you will use it every day from then on. If you eat apples once at the place of Liang County Magistrate, you will mostly use apples among all the fruits. Even tea is the same. If you drink it once and find it tastes good, you will not use the same tea again.

The only thing that is a little more variable is the food and snacks.

Lin Si closed her eyes and let Chunyi tie her hairband. The weather gradually became colder. She had been in Li County for nearly three months.

Three months is not a short time. Lin Si was surprised to find that she had grown taller. Then she came to her senses and realized that growing taller was normal. She was only ten years old and it was the time for her to grow.

"County Lady, the hairband is tied." Chun Yi looked at Lin Si's neatly combed hanging bun in the mirror, with two colorful silk hairbands tied on it, and she was satisfied no matter how she looked at it.

The children in the manor had started classes for two months. Although Lin Si had only been there once, Qian Sui reported everything in detail every day.

Last month, Lin Si went to the county magistrate's office to look for Liang Nian and Zuo You.

Liang Nian was shocked when he first learned that Zuo You was a teacher, but he gradually accepted it and is now accustomed to it. Sometimes when he sees Zuo You leaving home in the morning, he even reminds her to drink more water while teaching.

Liang Nian didn't expect that Zuo You and Lin Si would call her to discuss something.

Liang Nian: That’s great, I don’t have to eavesdrop this time.

Zuo You and Liang Nian looked at each other, unsure what kind of matter required their simultaneous presence. Could it be that something related to both the children of the manor and the government affairs of Li County?

Lin Si opened his mouth with a powerful blow, "I see that the agricultural conditions in Li County are poor. It's not just the farm tools that are the problem, the soil is the main problem."

Liang Nian felt the same way and could only sigh, "What the county lady said is absolutely right, but the quality of the soil is innate. I have tried many methods, but they have never worked."

"I came to see you two today just to resolve the soil issue." Lin Si said seriously.

Liang Nian was a little bit unconvinced, and his voice even trembled. "Does the county lady really have a solution?"

Liang Nian has always known that the soil in Li County is not good, but he has never found a way to change it. If Lin Si really can find a way...

Liang Nian suddenly felt that he had nothing to repay.

Lin Si glanced at Zuo You and said, "I do have a method, but I need to experiment and explore before I can pass it on to the people."

Zuo You suddenly had a bad feeling in his heart.

"And these experiments will require Madam Zuo to lead the students in the manor to conduct them."

Zuo You: Does this have anything to do with me?

Lin Si was going to the manor today to see the conclusion of the fertilizing experiment that had been going on for more than a month.

It would be great if we could succeed before the people plant winter wheat.

The system mall provides several methods of "Fertilizing the Field", including nitrogen fertilizer made from nitrate soil, phosphorus fertilizer made from bone meal, and seaweed fertilizer. Lin Si did not adopt these three methods.

Li County’s current productivity is too low. Even if these two methods are successful, they cannot be mass-produced.

As for seaweed fertilizer, it is due to geographical reasons that Li County is not near the sea.

Lin Si chose the high-efficiency composting method and the high-efficiency green manure method. Both methods already exist in Dachen and only require improvement.

It doesn't sound so far-fetched when you say it out loud.

The ox cart slowly drove towards the manor.

The distance between the manor and the county lord's mansion is not far. After three months of traveling, Lin Si is still not used to the bumpy ride of the ox cart and even wanted to walk at one point.

But Chunyi firmly objected. How could a county lady walk by herself? Nanqiao was drowsy in the carriage.

Nan Shuang and Nan Qiao took turns going to the manor for classes this month, and occasionally expressed their confusion in front of Lin Si.

"That stone is obviously not that heavy, why can't they move it?"

"It's just running laps, why are you so tired?"

In response, Lin Si said, "They are only a few years old, so don't ask for too much."

Nan Qiao and Nan Shuang looked innocent: "But when I was young, I could move rocks and carry farm tools."

Lin Si:........

Inside the manor.

What he learned in this month was enough to overturn Zhong Diyan's cognition, so much so that when they started conducting fertilizer experiments, he no longer wanted to question why the dead soldiers needed to know how to farm.

This must not be a serious assassin, Zhong Diyan thought.

Leaving aside Chinese class, he felt that math class was similar to counting rods and numbers, but also different.

But simplifying numbers is indeed a convenient thing, such as the experiment No. 1 fertilizer that he is now recording.

Paper is needed to record experimental data. Therefore, when dividing into groups, each group was assigned a person with good handwriting to be responsible for recording. After all, paper is a precious thing.

There were four experimental fertilizer sites, and the twenty-four children were divided into four groups.

The group Zhong Diyan was assigned to was the high-efficiency composting method.

Dachen's composting method is to turn some organic matter such as fallen leaves, rice straw, and weeds into treasure, but it takes a long time, nearly a year to decompose, and the efficiency of fertilizing the fields is low.

The improved composting method that Lin Si exchanged from the system mall added animal feces and urine. Feces and urine contain urea and microorganisms, which can accelerate decomposition.

And use a layered method to make compost, with straw or hay on the bottom layer, manure and bean dregs in the middle layer, and the top layer covered with straw to keep warm and moist.

Turn it over every three days.

As long as the "Fertilizer Field Method" is correct, it will only take one month for the highly efficient compost to mature.

As for another high-efficiency green manure method, it is even simpler.

Dachen has already specially planted plants such as milk vetch and alfalfa as green manure.

You only need to add the root nodules of legumes with soil to the original green manure. The legumes and rhizobia can symbiotically fix nitrogen, and then spread it in the farmland.

Therefore, the experimental site for the children assigned to the high-efficiency green manure method was in the fields under Lin Si's name.

The children on both sides envied each other. Those who used the composting method envied those who used the green manure method because they didn't have to deal with feces all day long.

Those who use the green manure method envy those who use the compost method because they don’t have to work hard to turn the soil in the fields.

Liang Nian attached great importance to this fertilizing experiment. Every day when Zuo You came home from get out of class, Liang Nian would ask about the progress of the experiment. He wished that it would succeed immediately and spread the news to the people.

Today is the day of acceptance. She came with Zuo You and arrived earlier than Lin Si.

Qian Sui was waiting at the door early and led Lin Si into the manor's gate.

Today each group will send one person to summarize. The children in several groups discussed it again and again yesterday and were very nervous.

This time we are reporting and summarizing directly to the host, and no one wants to fail at the critical moment.

What if you make the master unhappy and get kicked out?

Liang Nian and Lin Si were getting anxious, walking back and forth on the playground of the manor, looking at the door from time to time.

Finally, when Lin Si's ox cart arrived at the gate of the manor, Liang Nian's first reaction was that the young lady had grown taller.

Liang Nian didn't waste time talking or chatting, "I have been waiting for the county lady for a long time."

Qian Sui said respectfully, "Liang County Magistrate and County Lady, please follow me over here."

Liang Nian thanked him politely, and followed Qian Sui with Lin Si to a small open space in front of the manor.

Liang Nian saw at a glance a pile of compost covered with straw on the open space. Six children were squatting around it, holding a piece of paper and talking about something.

Qian Sui walked ahead, "The county lady and County Magistrate Liang are here."

Several children stood up in a panic, and the six of them stood in a neat row, bowing politely to Lin Si and Liang Nian.

"The county lady is well, and County Magistrate Liang is well."

Liang Nian was a little surprised. It was the first time she saw these children. She only knew that these children were originally slaves and beggars, but looking at the way they saluted with dignity, they didn't look like slaves at all.

Qian Sui continued to learn throughout her life. When she was teaching simplified numbers, she also listened to the class outside the window. After returning home, she learned it silently by herself and now she can recognize it completely.

Qian Sui introduced to Lin Si and Liang Nian, "This is the High-Efficiency Composting Experimental Group No. 1." He then gestured to the children to introduce themselves.

After the six children finished introducing themselves, Zhong Diyan picked up the data recorder and began to report to Lin Si.

The report was very concise, with all the key points and no nonsense. Zhong Diyan was not nervous or stuttering, and Lin Si and Liang Nian both listened very attentively.

Liang Nian would ask some questions that concerned her from time to time.

The final conclusion is that high-efficiency compost only takes one month to mature.

Liang Nian was so shocked that he almost couldn't stand.

One month! You should know that traditional composting methods take at least eight months to mature.

Lin Si was very satisfied with Zhong Diyan's report and added, "This method not only matures quickly, but also has twice the fertility of the original composting method."

After Zhong Diyan finished his report, he obediently stepped aside and did not participate in the discussion between Lin Si and Liang Nian.

Before Liang Nian and Lin Si left, Lin Si nodded slightly to the children headed by Zhong Diyan.

“The data is well written and reported.”

The children hurriedly thanked him, and only after Lin Si and Nian Er walked away did they begin to show their childish nature after being praised.

"Didn't the county lady just praise us?"

"Great, we've been praised by the county lord!"

"Die, the county lady praised you."

High-efficiency composting No. 2 and No. 1 use the same method. The reason for dividing them into No. 1 and No. 2 is to prevent the experiment from failing midway.

Experiment No. 2 was also successful, but the data and report were slightly inferior.

Next is high-efficiency green manure.

High-efficiency green manure was applied in the fields. The children spread high-efficiency green manure on half of the field, and did not spread fertilizer on the other half. The children planted a little wheat in each area.

The person in charge of reporting at the Green Manure No. 1 Experimental Field was a little girl with a melon-shaped face named Yang Yidong.

Yang used his clear eyes to point out the differences between the wheat grown in the two areas to Lin Si and Liang Nian.

Liang Nian could clearly feel the difference between the wheat in the two fields. In the area where high-efficiency green manure was applied, the wheat grains were round and full, and of superior quality.

This kind of wheat is rarely grown in Li County.

Green manure seems to be more efficient and simple, but Lin Sique knows the disadvantage of high-efficiency green manure, which is the problem of the number of soil-carrying root nodules of legumes.

After listening to all the fertilizer trial reports, Liang Nian excitedly held Lin Si's hand.

"Winter wheat will be planted soon. If we teach the people about efficient compost and green manure, wouldn't we have a bumper harvest?"
