What is it like to communicate with two powerful people? It's like in the world of Devouring Starry Sky. You, a star-level or cosmic-level warrior, meet a cosmic lord, and the two sides have almost no interaction at all.
Even the direct descendants of those Universe Venerables are almost rarely seen.
People who reach this level are also the top experts in the entire Swallowed Starry Sky, and those who are even higher up are the overlords of the universe.
Standing at the pinnacle of the universe, the only ones who can surpass these are the most powerful people in the human race.
So how can a small cosmic level communicate with such a powerful person?
But right now, Su Fan is communicating with Dayu and Zhen Yuanzi. Of course, the two of them seem to know that there is a huge gap between them.
Therefore, when communicating, I also deliberately took care of Su Fan, and the communication was mainly based on his topic.
What Dayu talked about were some medical classics and some things related to farmers.
Su Fan also understood that when Dayu came over, he brought out some knowledge systems.
Naturally, Su Fan had nothing to hide from Dayu. After all, he was the Human Emperor and the backbone of the human race.
What is Su Fan? He is a human contact talent.
And he also understood that Dayu's arrival was to protect him secretly.
To be honest, Su Fan felt warm in his heart. A quasi-saint-level strongman protected him, which showed that Huoyundong valued him very much.
So he also told some of the content behind the farming work one by one.
He used to only provide fertilizer for farming, but it has increased the yield per mu of the field a lot.
But the yield per mu is still very different from that of later generations.
Nowadays, even with the use of new fertilizer technology, the yield per mu is only equivalent to more than 250 kilograms in later generations.
You must know that one acre of land in Da Qin at this moment is one and a half times larger than in later generations.
In later generations, the wheat yield per mu reached about 700 to 800 kilograms, which was only one-third or one-quarter in later generations.
The difference is still huge.
In later generations, wheat has been optimized from generation to generation to become superior varieties, coupled with planting technology and fertilizer technology, especially the emergence of chemical fertilizers.
The fertilizer technology that Su Fan came up with was just a crude use of organic fertilizer.
Of course, chemical fertilizers are stronger, but in later generations, organic fertilizers gradually began to be used to replace chemical fertilizers.
Although the effect of chemical fertilizers is good, its advantages and disadvantages are also obvious.
Chemical fertilizers have simple ingredients and high nutrient content; they are fast and powerful; they generally do not contain organic matter and have no effect in soil improvement and fertilization.
Long-term application will increase the content of heavy metals and toxic elements in the soil; reduce the activity of soil microorganisms, making it difficult to transform and degrade substances; cause nutrient imbalance and nitrate accumulation; increase acidification, and cause excessive pH changes, etc.
Organic fertilizers are different. Compared with chemical fertilizers, organic fertilizers have complete nutritional elements; they can improve soil; improve product quality; they can improve crop rhizosphere microorganisms and improve plant resistance to diseases and insect pests; they can promote the use of chemical fertilizers and improve chemical fertilizers.
Utilization rate.
Organic fertilizers also have disadvantages. Although there are many types of ingredients, the content of each nutrient is relatively small and the results are relatively slow.
In this mythical world, can we develop chemical fertilizer?
Of course. Although the original laws of the world of later generations and the world of myth are somewhat different, the microscopic particles are still the same.
Su Fan can also observe those elements with the power of his soul. Su Fan even has a lot of fertilizers that he has developed himself.
It's just that his fertilizer is produced by his magic power and cannot be produced on a large scale.
In this era, if you want to manufacture fertilizers on a large scale, you must either take out the production equipment, or just like him now, use the ability of a monk to make fertilizers.
The first method, those production equipments are not that easy. Even if Su Fan can research them one by one and then refine them using weapon refining methods, I am afraid it will be very troublesome to implement.
The knowledge system requires countless people to delve into it.
As for the second method, Su Fan thinks it is simpler, that is to use monks to make fertilizer.
Ordinary monks, even those in the Qi refining stage, can do it, as long as they come up with the refining method.
Whether there are many monks in Da Qin, there are definitely many.
There are definitely hundreds of thousands, and if they are all used to refine fertilizers, it will be relatively easy.
Of course, the implementation of chemical fertilizers can only depend on the ideas of the Qin government. If they are willing to implement it, grain production can be increased on a large scale.
However, with organic fertilizer, it is relatively easy.
For example, the fertilizer technology Su Fan came up with before is actually the simplest type of compost.
Naturally, Su Fan does not only make this kind of compost. The kind he promotes is most suitable for large-scale implementation. The remaining ones are definitely more effective, but they are more difficult to implement.
After all, most ordinary people cannot accomplish it.
But if the government does it, it will be much simpler.
Su Fan did not hide any of these contents and told Dayu about them, especially chemical fertilizers and organic fertilizers.
The effect of chemical fertilizers is stronger. Although it also has shortcomings, it can greatly increase the grain production in the field in a short period of time.
"Is this thing easy to refine?"
Dayu couldn't help but be excited. After Su Fan took out the fertilizer, Dayu immediately deduced it. In an instant, he realized the effect of the fertilizer, which was simply terrifying.
There is no actual situation, but according to his deduction, it is no different from the field experiment, which can increase the harvest by half again.
According to the current situation in Da Qin, one stone is equivalent to about sixty or seventy pounds in later generations. The best farmland can have four stones. If it is increased by half, it will be six stones per acre.
This number is really too high.
Dayu knew very well that producing six stones of grain per acre was a huge improvement for the human race.
This means that the human race can reproduce more people,
Today's human race, not to mention other places, just the land of Kyushu, is still vast and sparsely populated.
Too many places are undeveloped.
Many places are not undeveloped, most of the wilderness is uninhabited land, either wilderness or woodland.
These can all be developed. The reason why the wilderness is not developed is that the harvest in the wilderness is not high. But now with chemical fertilizers, even the lower-grade wilderness can produce a harvest of three stones or more.
This can support a larger population.
Many children bring happiness, but in the past, a family in Guizhou could not raise so many people, but now that the grain harvest is large, it is different. In a few years, the family will have more and more food, and they can have more children.
Twenty years from now, the population will definitely explode.
Dayu was naturally able to deduce this scene. For the human race, the larger the population, the stronger the human race. This is a theorem, and it is nothing more than a refutation of the theorem.
Why did the Witch Clan want to combine with the human race? It was because it was much easier for the Witch Clan to give birth to offspring than the Witch Clan. ()
