Ming Dynasty: He was ordered to give lectures in prison, but Lao Zhu eavesdropped and made people nu

Chapter 192 The role of chemical fertilizers

Lin Che scolded him mercilessly.

The father and son of the Zhu family were sitting on pins and needles, looking extremely embarrassed, sitting there looking at each other.

The more trouble?
Die sooner!
After a while.

Only then did Zhu Fang regain his composure and saw his father and elder brother sitting in silence on their chairs. He was about to explain a few words, but was stopped by Lao Zhu's stern eyes.

However, Zhu Xiang had been studying with Lin Che for a while, and he also knew that there were some topics that he should not touch. The more he touched on them, the more embarrassing the situation would become.

He suddenly thought of the sweet potato seeds he took from his father and planted them in his yard, but the results were not good.

The seeds have been wilting since they were planted, and he is worried that if this continues, the sweet potatoes will die due to poor planting.

So he decided to change the subject and asked:

"Sir, since the pictures of sweet potatoes and corns that you drew for us last time, my father has sent people to search for these two plants across the country."

"I didn't expect that my father would actually find me."

"We tried planting the sweet potato seedlings we found, but the growth was not as expected. We were worried that our method was wrong."

"Please advise sir!"

After hearing this, Zhu Yuanzhang felt the same way. The sweet potato seedlings he planted in the Imperial Garden had a similar situation.

He was troubled by this, and when he heard Zhu Xi mention it, he immediately listened attentively.

"Food plant cultivation and yield are not only related to temperature, but also to seeds, fertility, and environment."

Lin Che did not dwell on the previous topic, but picked a piece of meat with chopsticks and stuffed it into her mouth, chewing while explaining.

"Sir is quite right."

Zhu Xi nodded, in fact, no crops, even plants, can escape the above laws.

It is said that oranges grown in Huainan are called tangerines, and those grown in north Huaibei are called tangerines. The leaves are similar, but their tastes are actually different. Why?Water and soil are different.

It is obviously the same plant, but it looks completely different after changing the environment.

After hearing the above words, Zhu Yuanzhang next to him asked:
"Fertility? As far as I know, manure is used as fertilizer nowadays, but manure is limited and cannot irrigate a few acres of land."

After saying this, Zhu Yuanzhang suddenly felt that something was wrong, and then he thought that he was eating, and when he talked about feces, it seemed that something was not good.

Fortunately, Lin Che didn't care at all and continued to chew the meat and replied:
"Manure is also a type of fertility. When I say start with fertility, I mean chemical fertilizers."

Lin Che nodded. In ancient times, human and animal excrement was most commonly used to water the ground.

Farmers in rural areas even fight over excrement, which shows how difficult farming is.

"Mr. Lin, what is this fertilizer?"

Before Zhu Yuanzhang could ask, Zhu Xi asked impatiently.

"As the name suggests, it is chemical fertilizer. It contains various nutrients needed by crops. If used properly, it can double the yield of crops."

“Also, this fertilizer is effective on all crops!”

Lin Che briefly explained the function and meaning of chemical fertilizers.

"Double it again?!"

hiss!
Zhu Yuanzhang took a breath of air-conditioning, this fertilizer has such a great effect!
impossible!Absolutely impossible!
So the sweet potato is 26 stones per stone, and then doubled, wouldn’t it be 52 stones?
One acre of land can produce four thousand kilograms of grain? !
But then I thought about what kind of person Mr. Lin was, how could he talk nonsense.

Zhu Ping, who was next to him, felt that he was going crazy with excitement when he heard this. He quickly closed his eyes to adjust his emotions.

moment.

Zhu Xi, who had calmed down a little, was still very excited, but it was still much better than before.He spoke before his father again:

"Sir, the yields of the sweet potatoes and corns you mentioned earlier are terrifying. If we have chemical fertilizers in the Ming Dynasty, and the yields can be doubled, they will rot in the ground and no one will be able to eat them all!"

"At that time, there will be a surplus of food every year, and we will no longer have to worry about famine?"

"Sir, I must know how to make this fertilizer. Don't hide it, sir, just tell us!"

Zhu Yuanzhang and Prince Zhu Biao also looked eager.

They were all affected by the scene rendered by Zhu Xi.

If this is the case, the Ming Dynasty has nothing to worry about. It will definitely be passed down for thousands of years.

At this moment, Zhu Yuanzhang began to imagine the picture of a bumper harvest in his mind, and the people no longer had to live so hard for stuttering.

Thinking of this, Zhu Yuanzhang couldn't help but get excited.

"This sweet potato and corn can be stored for a long time. This is rare in rotten fields."

"As for how to make this fertilizer, I can do it."

"But before I talk about how to make fertilizer, I have to tell you what kinds of fertilizer there are."

Lin Che saw the three fathers and sons of the Zhu family with longing expressions on their faces, which also added fuel to their fire.

It turns out that sweet potatoes and corn have so many benefits.

It is edible, has a large yield, and can be stored for a long time. Except for its low nutritional value, sweet potatoes and corn have almost no shortcomings.

Zhu Xi was immersed in the divine objects described by Lin Che and could not extricate himself for a long time.

He glanced at Zhu Yuanzhang, and his father also yearned for him the same way.

Thinking that my father wanted to reach the prosperous Tang Dynasty in governing the country, there may still be a long way to go.

But he already foresees the near future!

The yield of crops in the Ming Dynasty can definitely far exceed that of the Tang Dynasty.

"First of all, fertilizers are divided into organic fertilizers and inorganic fertilizers. Although they are both fertilizers, their functions are completely different."

"The manure that His Majesty the Emperor mentioned earlier is a type of organic fertilizer."

"Organic fertilizer is farmyard manure, such as manure, rotting animal carcasses or rotting plants."

"Such as pig manure, chicken manure, various rotten leaves, plant ash, etc. can be used as organic fertilizer."

"The characteristics of this kind of fertilizer are its wide source of raw materials, large quantity, complete nutrients but low nutrient content. The fertilizer effect is late and long, and it takes a long time to be absorbed by crops."

Lin Che said this and picked up the wine glass but found that it was empty. Zhu Yuanzhang was about to take the wine jar to pour the wine. Prince Zhu Biao had quick eyes and quick hands. He quickly stood up, picked up the wine jar, walked to Lin Che's side and poured the wine.

Lin Che nodded, touched the wine glass to Zhu Yuanzhang, drank it all, and continued:

"As for organic fertilizer, it is actually mainly used to improve soil fertility, and the cost is to increase yield. The difference is probably that one is long-term and slow, and the other is short-term and rapid."

"Organic fertilizer is relatively simple. It is actually farmyard manure. For example, the tofu residue left from grinding tofu. Add some water and leave it in a warm place for a few months. It will turn into nitrogen fertilizer."

"The same applies to fish scales, bones and other objects."

"There is also an indigenous method of ammonia fertilizer. Take 100 kilograms of fresh cow dung, 50 kilograms of soybean powder, and 10 kilograms of plaster of paris powder. Mix them evenly according to this ratio. Place them in a kiln and suffocate them for three days. When fertilizing, add an equal amount of three times of fertilizer. twice as much water.”

Lin Che talked a lot in one breath, a lot of unheard terms, and everything the Zhu family said about the father and son was completely confusing.
