"Mr. Fang, do you take this seriously?" Li Zhen said.

"Of course, take it seriously! But you need to think about it!"

Fang Jun spoke.

As he was speaking, outside Nan Study Room, several people walked past the room. When they heard this, they couldn't help but stop and frowned.

On the other side, Kong Yingda, the Imperial College Priest, also came over. When he saw the people outside, he was stunned for a moment. He was about to salute, but was stopped by the man.

He signaled to the others and looked into the classroom.

I saw more than a dozen princes sitting upright in the classroom, all staring at the desk in front of the room, and a young man in a green robe was talking.

Of course it is not an important issue.

It is also somewhat of a way to investigate things.

But the statement is a bit novel, which makes people involuntarily stop.

The Tang Dynasty was short of food every year.

"Why do you think?" Li Zhen continued.

Fang Jun glanced at him and said slowly: "You have to think about three questions! First, why do you do this? What is the purpose of doing this? Second, how can you do it? How can you improve it? Third, do it

Can it be used after it is done? You must let go of your thoughts and think about what others dare not think about. You are all princes of the Tang Dynasty and should benefit me and the people of the Tang Dynasty! Only in this way can you do things well!

”

Li Zhi, Li Zhen and others frowned, a little confused.

Li Yuanxiang said, "Mr. Fang, what are you talking about these messy things? You haven't told me how to protect the farming!"

Fang Jun glanced at him and couldn't help but sigh and said, "I have already said that the root of farming is not the ox, but the plow! It is good to prohibit slaughter oxen, but it is actually a move to waste the roots and conquer the end! If you want to complete it

Your Majesty’s wish. So why not study how to make a plough!”

"Now, one ox and one plow in the Tang Dynasty can be used for about two acres of land! The power of the ox has been exhausted, but the power of human beings cannot be improved. Only by improving the plowing can it be done!"

"Today, your goal is how to easily plow the land with the least amount of animal power? As long as you can do it, then in the future, you can plow three acres of land or four acres of land with one ox in the Tang Dynasty in the future.

If there are too many plows, why worry about not being able to plant food? Why worry about not being able to maintain farming?"

Hearing this, people in and outside the room were slightly shocked.

Li Yuanxiang immediately said: "How is this possible?"

"What's impossible? As long as you dare to think about it, then it's possible!"

Fang Jun stared at him and said, "I can think of one for you! I'll give you some tips. That's a long straight plow! This plow says it's good or not, but if it's bad, then it's extremely bad! The one used is a straight plow.

, not only easy to break, bulky, but also difficult to turn, and it is extremely difficult to cultivate the land! We can start with the straight shaft and change the straight shaft to the curved shaft to see if it will be much better?"

"As we all know, the curved shaft is elastic. The greater the squeeze, the greater the rebound! If adopted, can it save half of the animal power? Even if you cannot save half of it, as long as you save 30%, it can greatly increase the speed of tenants farming?

Wouldn't it be beautiful?"

The person listening outside was shocked and his eyes widened.

A little short of breath.

Li Zhen, Li Yuanxiang and others in the room were also stunned for a moment, their faces were solemn.

After thinking about it, Li Yuanxiang said, "How is this possible? How can Quyuan be more useful than Shiyuan? I don't understand this!"

"Since you don't understand, then you can try first! Only by trying can you know the result! Don't be self-righteous and think this is impossible or that is impossible!" Fang Jun shook his head and continued.

"When it comes to plows, there are actually many things that can be improved. The plow wall, plow bottom and the pressure horn can be adjusted! For example, the long straight plow is relatively heavy and easy to overturn. Then adjust the plow wall, plow bottom and the pressure horn,

Make its center of gravity face down and increase stability, which not only saves manpower, but also saves animal power!”

"In order to adapt to the cultivation of different farmlands, a plow or plow arrow can be added. If the plow review is advanced, the plow arrow can be made downward, and the plowshare will be deep when it is penetrated into the soil. If the plow review is raised, the plow arrow will be made upward, and the plowshare will be shallow when it is penetrated into the soil.

!This way you can cultivate carefully.”

"There is also a plow wall, and we must continue to adjust it. The plow wall is very important. We must set a goal, that is, not only can we break the soil, but also push the plowing soil to one side, reducing the resistance to the plow's advance, and thus saving animal strength

.As long as you can do it one by one, then in the future, the tenants of the Tang Dynasty can cultivate five acres of land a day. Wouldn’t the food of the Tang Dynasty be flipped out? Why worry about not being able to protect farming?"

"So you're serious?"

After hearing Fang Jun say that, Li Yuanxiang, Li Zhi and others don’t say anything.

At this time, a loud sound suddenly appeared outside Nan Study Room, which scared everyone.

Fang Jun hurriedly turned around and saw Li Shimin, Fang Xuanling, Xiao Yu and others appear outside.

Fang Jun was stunned for a moment and almost choked.

Li Shimin walked in with excitement on his face and said, "Fang Yiai, do you take this seriously? Can the plow really do this?"

Fang Xuanling also had a serious face, staring at Fang Jun and frowned.

He didn't seem to have thought that his son would have these things? He was silently pretending to be a pig and eating a tiger in the Fang family over the years.

Fang Jun was amused when he heard Li Shimin's question.

When did this man come here?

Didn’t he read the memorial in Tai Chi Palace?

He is very leisurely lately?

"Jun'er? Why don't you answer Your Majesty's question quickly? That plough... can it really be done like this?" Fang Xuanling also spoke.

"this……"

Fang Jun glanced at everyone and saw that Kong Yingda was still behind, so he sighed and shrugged and said, "What I said now is one of the ways to think about problems and solve them! As for whether it is feasible, it is time for you to test it."

!Also, farming is not only about oxen and plowing, but also about the weather! And it also involves the seeds! Different seeds can plant different grains!”

Li Shimin was slightly shocked: "Seed? How to explain this?"

Fang Jun thought for a while and smiled and said, "It's very simple to explain! I wonder if you have ever thought about why some oranges are sweeter, while some oranges are sour? Why are some rice grains full and rice ears very large, but some

But it's very dry, very few?"

"Is there any truth here that we have not understood? As the saying goes, all things must be rough inside and outside, and every grass and tree contains the ultimate truth! Only by understanding the essence of it can we distinguish right from wrong!"

When Li Shimin heard this, he immediately looked at Fang Xuanling.

Fang Xuanling frowned and said, "The reason is simple, but it is very difficult to do!"

“It’s really hard!”

Fang Jun nodded and said, "But there are also simple things! Take the farming protection just now. Can we clarify the inside clearly first?"

"For example, since there is something in it, we don't understand it for the time being, so let's ignore it for now. Instead, do what we can see first? Let's use a simple method to increase the rice ears?"

"What kind of way?"

"For example, if we select the best and fullest rice ears from acre of land as seeds for cultivation, will the rice ears we planted be more fuller?"

"If it is not full enough, then we will continue to select the best and fullest seeds from it and continue to farm!"

"We will do this! We will gradually grow, cultivate for three or five years, or even ten or twenty years. You might as well guess whether we can plant the fullest rice ears? Is the food we plant in the future?

All the acres are extremely full, and the output is extremely high?"

"In the past, one acre could produce three stones, but if we did it, then one acre could produce four stones or five stones. Wouldn't it be possible to support more people?"

"This is ultimately one of the ways to think about problems and solve them! Not only to ensure farming, but also other things!"

"As the saying goes, everything must be exhausted, from near to far, from shallow to deep, from rough to fine. Learn, interrogate, think carefully, and distinguish them clearly, and form four stages, and enter them heavily.
