In Jingmen's phosphate rock resources, Kuang Rongguang carved out a huge ore belt, from Huji to Shuanghe to Yangwan, which is basically the same as that of later generations.
This article was first published by The safer area is Yangwan, close to the Han River, close to Zhongxiang and Jingmen, and water reinforcements will be more timely.
However, the study group did not study the question of how to mine it.
Kwong Rongguang's excavation of the trench in the mountain attracted the attention of the research team.
As a result, the opinions of people from the Institute of Microbiology and the Institute of Agriculture dominated.
Because although the humus layer exposed by the trench is of different thicknesses, it has a large number of organisms and microorganisms.
Zhang Yue rushed over with equipment and personnel from the Agricultural College.
This girl has become the director of the Rice Institute of the College of Agriculture.
When Zhang Yue studied the biome of rice soil, she found that there were more biomes in flooded rice soils than in dryland paddy fields, and different microbial populations seemed to have different preferences and different chemical characteristics after death.
During cultivation, it was found that some biological clusters have a preference for phosphorus, potassium, nitrogen, and other elements.
They will absorb these elements from the soil.
After death or excretion, it becomes a nutrient that is active and easier for plants to absorb.
All of these microorganisms live in symbiosis with plant roots and insects such as crustaceans.
Form a small soil environment in paddy fields.
And the thickness of this humus layer also determines the fertility of the soil.
Because the soil environment of the paddy fields is strictly controlled by the depth of ploughing.
So Zhang Yue's research turned to the soils of dryfed farmland and pasture grasslands.
The results showed that the humus layer of grassland with small shrubs was the highest.
Forestland is the second, and farmland is the lowest.
However, farmlands that use farmhouse manure are higher than farmlands that use biogas sludge alone.
But if the two are mixed, the effects will stack.
This is because the farmland straw is harvested and taken away.
The return rate is lower than that of woodland and grassland.
In the past two years, the College of Agriculture has promoted farm manure and biogas sludge in order to increase the rate of straw returning to the field.
Cotton producing areas are also studying the application of cotton stalks.
It is mainly the cultivation of edible mushrooms after powdering, then into fermentation and biogas digesters, and finally back to the farmland.
Zhang Yue concludes that the fertility of the soil does not depend on the amount of chemical elements, but on the number of biological populations and the amount of active substances produced.
This theory is already different from the West, and it coincides with Zhang Chun's environmental theory and system theory.
Zhang Yue came to Yangwan because.
Zhu's group found that the microbial populations in the humus layer above the phosphate rock are very different from other places because of the different soil chemistry.
According to Zhang's theory, the fertilizer must be mixed with the biome to ensure that the original soil activity is not destroyed.
Improve the utilization rate of fertilizers.
The technology of extracting and cultivating methane strains, farm fertilizer compound strains, and various edible mushroom strains has been matured in the microbial area.
However, since any kind of fertilizer is almost not composed of a single microorganism, but a series of biological communities working together to achieve the highest efficiency.
As a result, the planned phosphate fertilizer plant has eliminated the roasting and other refining processes provided by chemistry.
Instead, it is necessary to study a completely new biological phosphate fertilizer.
Of course, a new plant for phosphorus purification is also being built.
It's just that that's for chemical and military use.
It is used to make a burning # incendiary bomb.
When Zhang Chun arrived in Yangwan, more than a dozen research laboratories had already been put into use.
Zhang Chun's fears of a big job did not materialize.
This made Zhang Chun breathe a sigh of relief.
Zhang Chun affirmed the research direction of Zhu Anni and Zhang Yue.
It's just that Kuang Rongguang is a pity, because according to Zhang Yue's theory, at least the phosphate rock on the surface cannot be moved, because it is necessary to protect the trees and creatures above.
Even underground mining has many limitations because it inevitably causes changes in groundwater.

"Master Kuang, you can't count it like that.
The earth is an everlasting treasure.
As for underground mining, humans are nothing more than shells.
Drag things up underground for other creatures to use. ” The metaphor of Zhang Chun's image made everyone laugh.
Zhang Yue said: "There is a Jebsen foreign company in Jingzhou City.
Sale of ammonium sulfate of the Lion Horse brand, made in Germany.
There are also fertilizers from the United States of America and Japan.
It is said that it was originally converted into a military nitrogen manufacturing plant.
Jingzhou is shipped by foreign ships, and some of them have already been used in Shayang.
The increase in yield is obvious.
But there are also many problems, the main one is that this fertilizer acidifies the soil, ammonia is volatile in the soil, and both processes kill microorganisms in the soil in large numbers.
The end result is a decrease in biological activity in the soil, soil compaction, and a decrease in fertility.
So I have proposed to ban the use of this chemical raw material as fertilizer. ” "However, this chemical raw material works very well as a kit for cultivating yeast and some microorganisms that like ammonia sources," Zhu added.
The smelting institute uses it as a reducing agent and the effect is also good.
So the chemical industry is also trying to make it. to consume sulfuric acid produced by power plants and desulfurization units of copper and iron plants. ” "The copper and iron plant has found some microorganisms that can survive in weakly acidic substances and can replace metals such as copper and iron, and it is good to use them to treat low-grade ores.
Some bacteria are also ammonia-ophoric when cultured. ” "The problem is to prevent farmers from using this fertilizer in large quantities for short-term yields," Zhang concluded.
The humus layer in the soil cannot be cultivated in a year or two, and the formation time may be hundreds or thousands of years.
However, the use of these fertilized fields has completely destroyed this information in a very short time.
And all the measures we have done in the past to evolve the soil and increase the fertility of the farmland will be destroyed.
So I still suggest that the import of this purely chemical fertilizer be banned. ” As for agricultural technology, some aspects of the College of Agriculture have reached the height of the agricultural institute where Zhang Chun was located in the later generations.
Now the difference is only in the test equipment and testing equipment, if there is a breakthrough in this, the agricultural college will even soon be involved in genetic research and genetic research.
Therefore, Zhang Chun not only expressed his support for Zhang Yue, but also used the experience summed up by countless failures in later generations to make them avoid detours and support them financially and materially.
Kwong Rongguang frowned during the whole process.
Coming out of the laboratory, Zhang Chun proposed to go for a walk in the mountains.
Jingzhou, Jingmen and Xiangyang have always been places with large populations and developed economies.
The gentry class here used to be very developed, but in recent decades, from the Taiping Army to the Twist Army, Liu Ying's uprising to Li Tiancai, almost all of them were in the core areas where the army fought back and forth, and a large number of gentry classes had to go to Wuhan to avoid trouble, and a large amount of land was sold cheaply.
Land is highly concentrated and has a certain dispersion.
In these two regions, there are more yeoman farmers and wealthy farmers whose families own a certain amount of land.
This is also the reason why there are a large number of rich children in the road construction army, although they own land, they are not separated from labor like the landlords.
They responded to Zhang Chun and did not oppose the land policy because the land policy did not hurt them much, and it could even increase the amount of land they owned.
Even if all the forests were taken back to the state, it did not prevent them from going into the mountains to collect mountain goods, and in fact allowed them to have more extensive mountains and forests than before.
Of course, there are still those who are hurt.
That's the big landlords.
This mountain forest in Yangwan belongs to a large landowner surnamed Yang.
He once led the township group to confront Gu Ming, and the ending was naturally not good.
It is said that more than 300 bodies were buried in Yangwan.
Although the army is gone, the members of the research team and the working group have come with guns.
"I have received a lot of support from Mr.
Yang in this generation, but I didn't expect such an ending."
Kwong Rongguang sighed.
"Do you know why he led the township regiment to resist?
You must know that he is behind Gu Ming, not to talk about anything else, just to keep the back road, Gu Ming will not allow such a threat to exist.
Zhang Chun asked as he walked.
Mr.
Yang owns most of the forests and land here, and almost the entire phosphate mining area is in his home.

Since I came here, Mr.
Yang has been very cooperative, and Mr.
Yang has a good reputation among the people, he has not bullied men and women, bullied the people, and took good care of the tenants. ” "Hehe, that's for the sake of profit."
"It should be that the township regiment in Yangwan has a lot of people, one or two thousand people, in addition to rifles, machine guns and artillery.
Master Gu once asked him to surrender, but the negotiation was not successful.
Mr.
Yang demanded that the land law should not be implemented and that no reform be carried out in his place.
Can't we make peace with such enlightened gentlemen?
Kuang Rongguang smiled bitterly before saying, "But I understand now, at least the students of Xinmin University will not allow Mr.
Yang to exist."
Sooner or later, he will be forced to rebel by the students. ” "Oh?"
Zhang Chun asked.
"Mr.
Yang had a big mining plan when I surveyed the phosphate rock, and he had already negotiated with foreign companies to introduce equipment and technology, and foreigners accounted for 70% of the shares.
I used to think it was a good idea, even though I didn't care about mineral development.
But I thought about recommending it to you.
Because it can bring a large amount of income in a short period of time, it can strengthen the country and the army.
Kwong Rongguang fell into memory.
"Yang Wan had an accident, I hurried over, thinking that I could still implement this method, but now it seems impossible.
Because the students have their own system, and the economy they advocate also has its own system, which is completely different from the West.
It is also completely different from the survey and design theory I studied before.
At least I didn't think about the role of the humus when I opened the trench, and I didn't think about the question of whether the forest destroyed by open pit mining or the ore underneath was more valuable. ” "The students are not against mining, it's just that the way it is mined may be different."
Zhang Chun comforted.
"It's not the way of mining, it's the way of thinking.
I decided to go to various research institutes as part of the research team.
At the same time, he will also ask President Cai for a group of people.
No wonder Wang Renbin told me that it is necessary to form a special mine design institute, to brainstorm ideas, and not to act arbitrarily.
Kwong Rongguang smiled bitterly.
