Rebirth Starts From 2006

,!

In the rural fields of Xijiang in the first month of the year, the crops have already been harvested, and it has not yet reached the early spring planting season. Only the roots are left standing in place, mixed with a little bit of white snow that has not had time to melt, and the white, black and yellow are mixed together, which looks more or less. depression,

In a vast expanse of land, criss-crossing field ridges divide the land into irregular small grids.

Because this is a hilly area, there is rarely a large area of ​​flat land. In addition, there are many water areas in Xijiang County, many tributaries of the Yangtze River and numerous lakes, which makes the fields here not as open as in the north. , not as three-dimensional as Southwest,

The whole building presents a sense of sophistication like the houses with small bridges and flowing water in the Jiangnan area.

Chen Yang squatted on the ridge of the field, looking at the large field in front of him, listening to long paragraphs of professional vocabulary in his ears, and his mind was full of confusion.

The experts from the Academy of Agricultural Sciences next to me were 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 parent material is Quaternary red clay. The effective soil thickness ranges from 40 to 100 centimeters, and the texture is sticky and heavy. The soil is clay to clay. The surface soil is bright red in color, and a large number of iron-manganese rubber films and reticulated layers can be seen in the profile, with strong aluminum enrichment.

There are many crops suitable for planting in brown-red soil, including tea, tung oil, camellia oleifera, fruit trees, rapeseed, wheat, sweet potato, pasture, slash pine, masson pine, fir, etc.

Generally speaking, undesirable characteristics such as heavy soil texture, poor structure, acidic to strongly acidic reaction, and low nutrient content are the main attributes of brown-red soil.

Although this kind of soil is suitable for rice cultivation, draining the water and converting it to dry land can achieve better results for cash crops.

Another great feature of the soil in Xijiang County is that it was originally a low-lying area of ​​water. This piece of land was only exposed after the water level dropped many years ago. Therefore, the organic matter content in the soil is very rich and has great potential. Operation space,..."

Chen Yang grinned and pretended to listen carefully.

No way, the expert who looks like an old farmer in front of me is not only a doctoral supervisor of the Academy of Agricultural Sciences, but also an extremely rare "Academician of both Academies", that is to say, he is both an "Academician of the Academy of Engineering" and an "Academician of the Academy of Sciences" "Dual identity,

Just like this, ah, national treasure-level figure, no matter whether he understands the ways of the world or not, he Chen Yang must understand the ways of the world. Even if he is a foil, he must accompany him attentively and without any negligence.

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, do you mean that this kind of soil can actually be improved?"

In fact, he just asked casually to express that he was really listening attentively, 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 by using multi-disciplinary theories and technologies such as soil science, biology, and ecology to eliminate or prevent adverse effects on crop growth and soil degradation. 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 space for manipulation. However, soil improvement cannot be achieved overnight, and some short-term benefits will be sacrificed at the same time. "

Chen Yang quickly asked, "What are the short-term benefits you are talking about?"

He was really afraid that Academician Wu would continue to popularize science and he would not be able to understand what he was listening to. It would be inappropriate to interrupt, so he could only change the topic.

What's more, this is also the main purpose of Zhou County looking for him today.

Yesterday at Wan Jing’s wedding, Zhou County asked a question:

Regarding the ecological agriculture development plan in Xijiang County, it was originally going well. However, several academicians, one on the left and one on the right, thought about it together and decided to make changes to the original plan.

However, not all academicians firmly supported this modification. 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 for discussion, the conflict of opinions will become even greater.

The day before yesterday, they fed back their opinions to Zhou County. This is also the reason why Zhou County did not tell Chen Yang last time.

It hadn't happened yet at that time.

After Zhou County got their opinions, he couldn't make up his mind, so he summoned people from all relevant parties to discuss it together. This time it was even worse.

It turned out that just like before, the more people argued, the more chaotic it became. Not only did there not be a unified opinion, but some people also raised objections to the original plan.

Zhou County had no choice but to think about it, and finally found Chen Yang.

If Chen Yang can provide a reference, it should be of great help in settling differences!

What is the problem?

It’s about the choice of agricultural planting methods in Xijiang County.

The original plan was to gather as much land as possible in Xijiang County and carry out unified management planning. After forming a certain planting scale, it would be more competitive in the market.

At the same time, on the private land in residential areas of each village, we should do a good job in ecological agriculture, combine ecological agriculture with farmhouse tourism, and make good use of the rich water network advantages in Xijiang County to create a combination of large farms, small farms and An eco-agricultural tourism model that integrates specialty tourism.

Originally, this plan was going well. Throughout last year, Xijiang County had integrated more than 90% of the transferable land. Some places even started large-scale agricultural operations, leveling large areas of land and turning them into The fertile fields are as open as those in the north, and large agricultural machinery can be used for farming, which greatly improves production efficiency.

If it hadn't happened the day before yesterday, after the Spring Festival, Zhou County would have started to organize more agricultural machinery to be put into large-scale farming, and all the more than a dozen major large farms in the county would have been leveled and planted according to the plans made in advance. We produce various crops and supply them to many food companies in the Xijiang County Economic Development Zone, as well as Auntie Wang’s Fresh Food Store in Guangdong.

At that time, with large-scale agriculture as the basic base, ecological agriculture and tourism as the starting point, and 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 for 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 benefits are naturally the difference in output value between large-scale agriculture and soil improvement, which must use traditional small-scale farming methods."

Chen Yang blinked, trying to understand what Academician Wu meant, and then said,

“You mean, if we choose soil improvement, then we can’t use large farm machinery for farming, so the efficiency will be lower and the yield will be lower?”

"Yes,"

Academician Wu first nodded to confirm, and then said, "But this difference in output value will only exist in the short term. If the timeline is extended to ten years, after ten years, the difference in output value will be reversed.

After the soil has been improved, the crops produced will have higher yields and values ​​due to the high quality of the soil.

On land cultivated with large-scale agricultural machinery, after years of squeezing the soil, the soil quality will be severely degraded.

In addition, in order to maintain crop yields, a large amount of chemical fertilizers and pesticides are also needed, and even crop seeds have high requirements, which will cause very serious damage to the soil.

At that time, large-scale agriculture will fall into a bottleneck and cause certain harm to the environment.

From this aspect, this point also conflicts slightly with Xijiang County’s ecological construction strategy. "

Chen Yang smacked his lips, thought silently for a while, turned to look at Zhou County, and asked, "What are your objections to soil improvement?"

Zhou Xian said with some hesitation, "This is more complicated. First of all, it's not that everyone completely disagrees with the plan of soil improvement and using traditional manual methods.

The key point is still about profits. Last year, weren't there a few places that took the lead in setting up large-scale farm demonstration gardens? The results were pretty good. The farmers who transferred the land got a lot of money, which was much better than farming on their own.

So this year there are many people waiting to share 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 at all, it's not true. They just want to engage in large-scale agricultural machinery cultivation for a few years. If the kind of soil degradation that the academicians said really happens, it will not be too late to improve the soil in turn. Well,

And after several years of accumulation at that time, both politicians and ordinary 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 difference of opinion is the question of whether to choose to develop first and then govern, or to choose first to govern and then develop?"

Zhou Xian rolled his eyes and grinned, "If I don't say that Director Chen is far-sighted, he can clarify the essence of the problem in one sentence!"

Chen Yang sighed softly, "Don't flatter me at this time. I mean Zhou County, shouldn't you be the one making the decision on this kind of issue?!"

Zhou Xian laughed and said, "Yes, yes, it was me who made the decision. Well, actually it was not me alone. It should be our county committee team who discussed it together.

But isn’t it still the stage of soliciting opinions? You are also the one we are soliciting opinions from!

I invite you here today for no other reason than to hear your opinion. It’s that simple! "

Simple shit,

Chen Yang couldn't help but roll his eyes when he heard this. This old guy is very bad. As long as he gives his opinion, he will definitely throw it out to everyone tomorrow. He also 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 whether he takes the blame or not. Chen Yang doesn't care about this either. What he thinks about is which option is really beneficial to Xijiang County.

This so-called "development first and governance later" is different from the one that damages the environment. Large agricultural machinery and a certain amount of chemical fertilizers and pesticides will definitely cause certain damage to the soil, but this damage will not cause damage to the entire ecology. environmental deterioration,

Otherwise, the country has long banned the use of large-scale agricultural machinery, and there would be nothing to do with those large farms in the north!

Therefore, Chen Yang did not rush to make a decision, but turned to look at Academician Wu and asked,

"Academician, I have a question. You said that large agricultural machinery will cause damage to the soil. How harmful is it?"

Academician Wu pondered for two seconds, then turned and waved to the students who served as assistants, "Bring me the test equipment."

Then he looked at Chen Yang and said seriously, "Director Chen, I will demonstrate it to you on the spot, and you will understand the difference."

Then the assistants brought two glass boxes and placed them on the ridge of the field. Two more people dug soil in the field and placed them directly in 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, this is original soil that has not been treated in any way.

Look at what's inside. I'll 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 components in the soil will definitely be lost. This is inevitable. result,

Finally, I squish the soil mixed with sand, imitating the squeezing of the soil by large farm machinery. "

What followed was a series of smooth operations.

After a while, in Chen Yang's eyes, the experimental process like that of a child and Niba came to an end.

At this time, Academician Wu picked up two more 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.

Academician Wu pointed to the glass box and said, "You have all seen that the original soil can effectively absorb water, and I don't think there is any need to explain the role of soil water on crops. You should all know it, right?"

Chen Yang and others nodded repeatedly.

Academician Wu continued, "Looking inside another box, you can clearly see that after the soil is mixed with sand and squeezed, its water absorption capacity is far less than that of the original soil.

And not only that, as the water washes away, these loose soils will be lost with the water. This is what people most often call 'soil erosion'.

Because the soil has lost its ability to absorb water, when rainfall is too heavy, the most valuable soil on the surface will be washed away by the rain.

With soil erosion year after year, the soil nutrients will be completely lost. At this time, the land on 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 natural recovery in a few decades.

Or they use a lot of chemical fertilizers to artificially fertilize the land. This is also the most common operation method of large farms at present.

However, this approach still causes objective damage to the land, and the crops produced on this type of land are far inferior to crops grown naturally, both in terms of taste and nutrition.

This is one of the reasons why the price of ecological crops in the market is much higher than that of farm crops. "
