I was watching short videos and was seen by ancient people

Chapter 283 Necessary for Time Travel—Making Soil and Chemical Fertilizer ()

"I'm very professional: It's better to use urine directly, use plant ash for potassium fertilizer, and use bone ash for phosphate fertilizer. This way the materials are easy to find and the effect should be good. 》

"Time to Give You a Song: Plant ash does not contain high potassium, bones do not contain much phosphorus, and overuse of the land will turn it sour and burn the roots. 》

People from all dynasties were brightened when they saw the comments on the canopy and the rear view on the canopy, asking people to directly use urine or plant ashes, bones and other things.

Compared with the soil and chemical fertilizers on the sky screen, these things are easier to find and use.

When they saw the second comment, their bright eyes dimmed again. They did not expect that the effect of these things was not good, and using too much would burn the roots of the plants.

At the same time, they were also rejoicing. Fortunately, it was freezing cold now, and they did not immediately take action to experiment with what the Third Eye said, directly using urine, plant ashes, ashes and other things.

At the same time, they also began to worry, does the soil fertilizer on the sky curtain have such side effects?

As for the people in places with warm weather in the south, they were full of regrets after seeing the comments on the sky screen.

Do their comments on the marquee have any effect in order to experiment? But I did exactly what was said on the marquee.

Some people even use a lot of what is said on the screen in order to get more output.

Now they regret it very much. Why can't they resist the impulse in their hearts and resist the temptation of high grain yield?

But there is no use regretting anything now, they can only find ways to make amends.

They found rivers and began pouring large amounts of water into their fields, hoping to dilute the water and protect their crops from harm.

The emperors of various dynasties looked at the comments on the canopy, and they were glad that they did not easily believe what was said on the canopy.

Otherwise, if it is implemented on a large scale, it would be good if it does not increase food production but does not reduce it.

However, he still ordered the officials to continue the experiment, after all, they could not escape the temptation of normal food.

And they felt that since the later generations of people in the sky had mentioned his shortcomings, there must be a solution.

What made them sigh was that the people of later generations did not tell how to solve the problem. They could only use these fertilizers carefully.

Wei State.

Jia Sixie looked at the comments on the screen and fell into deep thought.

As a professional in agriculture and the author of "Qi Min Yao Shu", a masterpiece that promoted agriculture, he had his own judgment.

In his opinion, if the soil and chemical fertilizers in Tianmu City are really effective, it will benefit all the people.

And if the direct use of plant ash and bones can increase the farmer's production, then that can also be used.

As for the roots of rotting plants, in Jia Sixie's opinion, these two substances can be diluted to achieve the effect of increasing food production without damaging the roots.

Later, his theory was popularized. Countless people thought about it and found it very reasonable. They decided to try it after the spring of next year.

They do not ask for their food to be as high-yield as that of later generations, but they only ask for a little more food so that they can have a full meal. Song.

Shen Kuo read the comments on the marquee, picked up the pen and paper in his hand, and recorded these contents in his "Mengxi Bi Tan".

Although these things have been broadcast on the sky screen and are known to the people all over the world, as time goes by, some people will forget it, and some people will even question it. However, when he wrote his "Mengxi Bi Tan", he hoped that He was able to demonstrate the effects of these things as well as their side effects.

At the same time, he began to focus on what potassium and phosphorus are. Because plant ash and bones contain a small amount of ingredients, they cannot produce a large amount of food. If there is a way to make the land have a large amount of these two ingredients, will the yield increase? Like later generations?

tomorrow.

When Xu Guangqi saw the comments on the marquee, he fell into endless silence.

At this time, the Ming Dynasty was experiencing constant disasters, and countless people were waiting for a mouthful of food to save their lives. If the method on the sky screen was really effective, he believed that His Majesty would definitely implement it.

Even if there are consequences, he will be asked to find a solution.

After all, in this era, one more mouthful of food can save one more life.

Moreover, His Majesty is a diligent master today, and he hopes that he can turn the tide and realize the resurgence of the Ming Dynasty.

Moreover, in Xu Guangqi’s view, His Majesty was born in the wrong era, otherwise he would definitely be a democratic generation.

It’s such a pity, so deplorable!

"Low-key Librarian: Some people talk about plant ash, compost and so on. How much urine do you think is needed, how much plant ash is burned, and where are the ashes? Without modern chemicals, the yield per mu would be less than 1/3 of what it is now. In ancient times, the yield per mu was only 200-300 kilograms. There is no way to feed so many people. 》

"Don't talk nonsense: Why is it called Tufa?" This is because these materials do not meet the conditions for continuous large-scale supply. In this way, fertilizers cannot increase the yield of large areas of cultivated land. 》

"The Trend of Industry: This is why it is called soil fertilizer. Native method = preparation method in the non-industrial era; time travel = non-industrial era. Wouldn’t it be great if you go to the farming civilization and use the relatively advanced native methods in the farming civilization era? You still want to reach the sky in one step. 》

When the various dynasties saw the comments on the marquee, they fell silent.

They also know that the method mentioned on the marquee cannot be used on all the land, but they still hold on to their hopes, at least the methods discussed on the marquee.

However, they wanted to know the results of the imperial court's experiment. After all, if they easily used soil fertilizers on their fields, they would not be able to bear the consequences.

However, in order to get the results of soil fertilizer as quickly as possible, they decided to open a small experimental field in their own fields and wait for experiments there next spring.

At the same time, they are also curious, what is the chemical industry in Tianmu from later generations to now? It turns out that we can get a large amount of chemical fertilizers that allow for high yields.

Not only were they curious, but the emperors of various dynasties were also curious, especially Zhu Yuanzhang. After all, it was said on the screen that the Ming Dynasty almost realized capitalism and allowed the entire society to industrialize.

What makes people sigh is that the Ming Dynasty was eventually annihilated by the Jiannu, and the civilization that the Han people worked hard to create was trampled down and buried in the heap of history.

And now they have comments on the sky, and they definitely don't want their dynasty to continue on the original path. They also hope that their country will become stronger and stronger, and their people will become richer and richer.

And their eyes are not only on the current territory, but also on the vast overseas world.

They must work hard to make the entire country richer and have more financial resources to occupy more land so that future generations can live richer!

It would not be possible for a certain dynasty to be invaded by the Eight-Nation Allied Forces and almost destroy the entire China!
