MTL - Rebirth Starts From 2006-Chapter 839 Field Test
【Rebirth from 06】【】
In the rural fields of Xijiang in the first month of the lunar year, the crops have already been harvested, and it is not yet the season of plowing in early spring. Only the stubble is left standing in place, mixed with a little white snow that has not had time to melt, and the white, black and yellow are mixed together. depression,
On a large piece of vast land, the criss-cross field ridges divide the land into small irregular grids.
Because this is a hilly area, there are few large areas of flat land. In addition, there are many waters in Xijiang County. There are many tributaries of the Yangtze River and many lakes, so the fields here are not as open as those in the north. , not as three-dimensional as the southwest,
The whole presents a sense of delicacy of small bridges and flowing water houses in the south of the Yangtze River.
Chen Yang squatted on the ridge of the field, looking at a large field in front of him, listening to a long list of professional vocabulary in his ears, his mind was full of fog.
The experts from the Academy of Agricultural Sciences next to me are still talking,
"The soil in Xijiang County is a typical brown-red soil, which is a soil type that transitions from red soil to yellow-brown soil. The soil-forming parent material is Quaternary red clay. The effective soil thickness ranges from 40 to 100 cm, and the texture is heavy. Loam clay to clay. The surface soil is bright red in color, and a large amount of iron-manganese film and reticulate layer can be seen in the section, and the aluminium-enrichment effect is strong.
There are many crops suitable for planting in brown red soil, such as tea, tung tree, camellia oleifera, fruit trees, rapeseed, wheat, sweet potato, grass, slash pine, masson pine, fir and so on.
Generally speaking, the main properties of brown red soil are bad characteristics such as heavy soil texture, poor structure, acid to strong acid reaction, and low nutrient content.
Although this kind of soil is suitable for rice cultivation, changing the water to dry land can have a better effect on economic crops.
The soil quality of Xijiang County also has a great feature, that is, the land here was originally low-lying, and it was a body of water. This piece of land was only exposed after the water level dropped many years ago, so the organic matter content in the soil is very rich and has great potential. Operating space,…”
Chen Yang grinned, pretending to listen carefully,
No way, this expert who looks like an old farmer in front of him is not only a doctoral supervisor of the Academy of Agricultural Sciences, but also an extremely rare "academician of the two academies". "Dual identity,
Just like this, ah, a national treasure-level figure, regardless of whether he understands the ways of the world, Chen Yang must understand the ways of the world.
Even though I don't understand it, I still have to listen!
After a while, Academician Wu stopped popularizing science.
Chen Yang took the opportunity to ask, "Academician Wu, what do you mean, this kind of soil can actually be improved?"
In fact, he just asked casually, expressing that he was really listening seriously, and this was the only thing he understood from Academician Wu's long speech.
But Academician Wu nodded seriously, and said seriously, "In fact, all soils can be eliminated or prevented from affecting crop growth and causing soil degradation by using theories and technologies of soil science, biology, and ecology. Factors, improve soil properties, increase soil fertility, and create good soil environmental conditions for crops.

The soil characteristics of Xijiang County have a very high room for manipulation. However, soil improvement cannot be achieved overnight, and some short-term benefits will also be sacrificed. "
Chen Yang hurriedly asked, "What short-term benefits are you talking about?"
He was really afraid that Academician Wu would continue to popularize science, but he would not be able to understand it, and it would be even more inappropriate to interrupt, so he could only change the subject.
What's more, this is also the main purpose of Zhou county looking for him today.
At Wan Jing's wedding yesterday, Zhou County asked a question,
It is about the development plan of ecological agriculture in Xijiang County. It was going well, but several academicians decided to revise the original plan.
However, not all academicians firmly support this revision, they just came to another conclusion, and then threw it to the Xijiang County expert group,
When the scope of the expert group is expanded before discussion, this phenomenon of conflict of opinions will be even greater.
The day before yesterday, they fed back their opinions to Zhou County, which is why Zhou County didn't tell Chen Yang last time.
It didn't happen back then,
After Zhou County got their opinions, he couldn't make up his mind, so he convened people from various relevant parties to discuss together, which was even more serious.
It turned out to be the same as before, the more people arguing, the more chaotic, not only did not have a unified opinion, but some people even raised objections to the original plan.
Zhou County had no choice. He thought about it, and finally found Chen Yang.
If Chen Yang can provide a reference, it should have a great effect on calming down the differences!
What is the problem?
It is about the choice of agricultural planting methods in Xijiang County,
The original plan was to gather as much land as possible in Xijiang County, carry out unified management planning, and form a certain scale of planting, which would make it more competitive in the market.
At the same time, on the private plots in the residential areas of various villages, do a good job in ecological agriculture, combine ecological agriculture with farmhouse tourism, and then make good use of the rich water network advantages in Xijiang County to create a collection of large farms, small farms and An eco-agricultural tourism model that integrates characteristic tourism.
Originally, this plan was going well. Throughout last year, Xijiang County has consolidated more than 90% of the transferable land, and some places have even started large-scale agricultural operations, leveling large tracts of land and turning them into The fertile fields that are as open as those in the north can be cultivated with large-scale agricultural machinery, which greatly improves production efficiency.
If there was no such thing as the day before yesterday, after the Spring Festival, Zhou County would start to organize more agricultural machinery to invest in large-scale cultivation, and level off all the dozen or so major farms in the county. All kinds of crops on the market are supplied to many food companies in Xijiang County Economic Development Zone, as well as Aunt Wang's fresh food store in Guangdong.
At that time, with large-scale agriculture as the basic platform, ecological agriculture and tourism as the starting point, and the factories concentrated in the county economic development zone as the driving force, the Xijiang model that has been floating in the sky will truly come to fruition and become a model of modern county economic development!
But isn't there another voice now?
So Boss Chen was dragged to the fields by him.

When Academician Wu heard Chen Yang's question, he immediately said, "The so-called short-term benefit is naturally the difference in output value between large-scale agriculture and soil improvement, which must use traditional small-scale farming methods for farming."
Chen Yang blinked, trying to understand what Academician Wu said, and then said,
"You mean, if we choose soil improvement, then we can't use large agricultural machinery for farming, so it will be less efficient and the yield will be lower?"
"Yes,"
Academician Wu nodded to confirm first, and then said, "But this kind of output value difference will only exist in the short term. If the timeline is extended to ten years, after ten years, the output value difference will be reversed.
After soil improvement, the crops produced will also have higher yield and value due to the high quality of the soil.
However, the land cultivated by large-scale agricultural machinery will seriously degrade after years of squeezing the soil.
In addition, in order to maintain the yield of crops, it is also necessary to use a large amount of chemical fertilizers and pesticides, and even have high requirements for the seeds of crops, which will cause very serious damage to the soil.
At that time, large-scale agriculture will fall into a bottleneck, and it will also cause certain harm to the environment.
From this point of view, there is also a slight conflict with Xijiang County's ecological construction strategy. "
Chen Yang smacked his lips, thought for a while, turned his head to look at Zhou County, and asked, "What are the opinions against soil improvement?"
Zhou Xian said with a little hesitation, "This is more complicated. First of all, it's not that everyone completely disagrees with the plan of improving the soil and using the traditional manual mode of operation.
The key point is still the benefits. Didn’t several places take the lead in setting up large-scale farm demonstration gardens last year?
So this year, many people are waiting for the money, and this is also the promise made by the county government to them,
But if you want to say that they don’t agree with it at all, they don’t. They just think about doing large-scale agricultural machinery planting for a few years first. If the kind of soil degradation that the academicians said really occurs, it will not be too late to improve the soil in turn. Well,
And after several years of accumulation at that time, both the government and the common people had more money in their pockets, and it would be easier to deal with it. "
Chen Yang blinked, and suddenly said, "Actually, the so-called disagreement is the question of choosing to develop first and then govern, or to choose to govern first and then develop?"
Zhou Xian rolled his eyes and said with a grin, "Either Mr. Chen is far-sighted, and he clarified the essence of the problem in one sentence!"
Chen Yang sighed softly, "Don't flatter me at this time, I said Zhou County, shouldn't this kind of problem be your decision?!"
Zhou County laughed, and said, "Yes, yes, I made up my mind. Hey, I'm not alone. It should be discussed with our county party committee team.
But isn't it still in the stage of soliciting opinions? You are also the object of our soliciting opinions!
I invited you here today for no other purpose than to hear your opinion, it's as simple as that! "

simple ass
Chen Yang couldn't help rolling his eyes when he heard it, this old guy is very bad, as long as he gives his opinion, he will definitely throw it out to everyone tomorrow, and said that he decided it himself,
This is not asking for opinions, it is clearly letting yourself take the blame!
But it doesn't matter if you don't take the blame, and Chen Yang doesn't care about it. What he thinks about is which choice is really beneficial to Xijiang County.
This so-called "government after development" is different from the one that damages the environment. Large-scale agricultural machinery and a certain amount of chemical fertilizers and pesticides will definitely cause some damage to the soil, but this damage will not cause damage to the entire ecology. deterioration of the environment,
Otherwise, the country would have banned the use of large-scale agricultural machinery long ago, so what about those large farms in the north!
"Samsara Paradise"
Therefore, Chen Yang was not in a hurry to make a decision, but turned his head to look at Academician Wu and asked,
"Academician, I have a question. What you said is that large-scale agricultural machinery will cause damage to the soil. How harmful is this?"
Academician Wu pondered for two seconds, then turned his head and waved to the assistant students, "Bring the experimental equipment."
Then he looked at Chen Yang and said seriously, "Chen Dong, let me demonstrate it to you on the spot, and you will understand the difference."
Then the assistants brought two glass boxes and put them on the ridge of the field, and two more dug the soil in the field and put them directly into the two boxes.
At this time, another assistant took out a bag of sand and handed it to Academician Wu.
Academician Wu said to Chen Yang, "Look at this, it's the original soil inside, it hasn't been treated in any way,
Look at it again, I will add some sand to it later, the purpose is to weaken the nutrients in the soil, because after large-scale and long-term planting, the ingredients in the soil will definitely be lost, which is inevitable result,
Finally, I will squeeze the soil mixed with sand, which is to imitate the squeezing of the soil by large agricultural machinery. "
Followed by a series of cloud operations,
After a while, in Chen Yang's eyes, the experiment process like children and mud came to an end.
At this time, Academician Wu picked up two bottles of water and poured them directly into the two boxes.
Within a few seconds, everyone present, including Chen Yang, Zhou Xian, and Zou Rong, saw the difference in the soil in the two glass boxes~www.novelbuddy.com~ Academician Wu pointed to the glass box and said, "You guys I have seen that the original soil can effectively absorb water, and the effect of soil water on crops, I don’t think I need to explain, you should all be clear, right?”
Chen Yang and the others nodded repeatedly.
Academician Wu continued, "Looking at the inside of the other box, you can clearly see that the water absorption capacity of the soil after being mixed with sand and squeezed is far inferior to that of the original soil.
And not only that, as the water washes away, these loose soils will be lost with the water flow, which is what is most often called 'soil erosion'.
Because the soil loses its ability to absorb water, when the rainfall is too heavy, the most valuable soil on the surface will be washed away by the rain.
With the erosion of soil and water year after year, the soil nutrient layer will be completely lost. At this time, the land of the so-called large farms will lose its original economic value.

There are only two results, either the deserted land is abandoned, plants are planted on it, and it waits for decades to recover naturally,
Either use a large amount of chemical fertilizers to artificially fertilize the land, which is the most common operation method for large farms at present.
However, this kind of practice still does harm to the land objectively, and the crops produced on this kind of land are far inferior to the naturally grown crops in terms of taste and nutrition.
This is also one of the reasons why the price of ecological crops is much higher than that of farm crops in the market. "
