One Thousand Five Hundred and Sixty-Three Agricultural Problems Are Very Serious

Many people may say, aren't you talking nonsense?

Who doesn't know that smog is caused by excessive exhaust gas from factories, and how is it related to the land?

Agriculture is all about eating according to the sky and planting the land. As long as the straw is not burned, how can it be bad to produce smog?

Why! It does matter, and it matters a lot.

Every spring ploughing season in our country, the haze weather is serious, which has a lot to do with the use of chemical fertilizers.

Because many rural areas in my country are now facing the problem of over-cultivation and degradation of land fertility.

Therefore, farmers use a lot of chemical fertilizers, especially nitrogen fertilizers, when farming.

The nitrogen in these nitrogen fertilizers volatilizes in the soil and turns into nitric oxide in the air.

Nitric oxide is one of the main culprits of smog, and this is not the most serious part of smog from fertilizers.

Another important element is the ammonia salt in nitrogen fertilizer.

Mainly in the form of ammonium sulfate and ammonium nitrate.

In the past, if farmers also used chemical fertilizers, but they were all used normally, there was no problem.

However, in recent years, due to over-cultivation, the fertility of our land has been degraded more and more severely.

Therefore, in order to ensure output, farmers have increased the amount of chemical fertilizers.

The more degraded, the more fertilizer is used, which leads to a vicious circle.

These ammonium salts are sprinkled into the ground with nitrogen fertilizer, and in addition to part of them are absorbed by the land, the other part will volatilize into the air to form ammonia gas.

Ammonia floats into the air and combines with the acidic waste gas discharged from the factory to form ammonium sulfate and ammonium nitrate.

Such smog often occurs in third- and fourth-tier towns where various small factories are concentrated.

For example, northern Hebei province, the Guanzhong area, and the Jiangnan area.

When the smog was at its worst, some people calculated that the concentration of ammonium sulfate and ammonium nitrate particles in the smog could reach 40%-60%...

In fact, such smog has appeared more than 20 years ago, but at that time because the monsoon in winter in my country was very strong.

Even if there is smog, it will be blown away by strong winds, so smog is not common in northern areas.

In the south of the Yangtze River, because there is a lot of rain, the smog just floated up and was photographed by the rain, so it did not attract people's attention.

But until the last decade, because of global warming, the average temperature in winter began to rise.

As a result, the monsoons in autumn and winter are not violent every year, and sometimes there is no wind for a week, which makes it difficult to disperse the haze.

Therefore, the smog in northern my country is particularly serious in winter. In summer, because of the large number of farmlands, photosynthesis of various crops will absorb a large amount of waste gas, so it is not bad.

It's only the worst in winter.

Among them, the Guanzhong area is the most serious, because it is surrounded by mountains and rarely winds in winter.

As a result, the smog here is often difficult to disperse throughout the winter. The same situation also occurs in Rongcheng and Hanjiang City.

On the other hand, in the areas of Jiangnan, Jiangsu and Zhejiang, because of the heavy rain, the haze weather can be alleviated.

However, it is precisely because the rain that the smog in the air falls to the ground and merges into the river, which has caused the heavy metal pollution problem in the area, which is particularly prominent...

It can be seen that our agricultural environment has been endangered to what extent.

And this time, the idea put forward by Chen Jianfeng is to carry out soilless cultivation.

When many people hear about soilless cultivation, they definitely don't like it very much. They say that this thing is not all made of chemical preparations?

Eh! Really not, the technical content of this soilless cultivation is very high.

The first is the configuration of the nutrient solution, which is really not as simple as mixing a variety of chemical preparations together.

Instead, it is prepared through a medium similar to normal saline, and then various trace elements and minerals are added to it.

And the advantage of this nutrient solution is that it is efficient!

For example, if you grow cabbage on the ground, some nutrients in this field may be liked by the cabbage, and some may not be liked.

Therefore, the growth cycle of cabbage will be longer.

But if you give the cabbage all the nutrients he likes, then it absorbs nutrients, saves time and effort, and he grows faster.

The growth cycle will be greatly shortened, and the efficiency of maturation will be higher.

And the most important benefit is that you don't have to worry about pests and poisonous weeds.

Farmers farming, the most troublesome is all kinds of pests, and weeds.

Weeds rob the soil of nutrients and hinder crops, not to mention pests.

However, if there is soil cultivation, it is inevitable to encounter weeds and pests.

This can be said to be a natural enemy that farmers cannot get around.

The first generation of genetically modified crops was actually developed to resist pests and lodging.

Later, in order to increase production, gene fragments that increase protein content were also added.

Although the benefits of genetically modified soybeans are many, so far, genetically modified soybeans are still relatively rejected on the market.

It is because scientists have added toxic peptides to the genetic fragments of genetically modified soybeans.

When this toxic peptide binds to the digestive enzymes in the pests, it produces a poison that kills the pests.

So that soybeans are free from pests and diseases.

Although scientific research has shown that this toxic peptide will not have any reaction with the digestive enzymes in the human body.

But what people can't guarantee now is that if you take this genetically modified soybean for a long time, it will cause other lesions over time.

Therefore, when people eat soybean oil and soybean products, they will try to avoid foods made from genetically modified soybeans.

But no matter what you do, you are actually suspected of taking off your pants and farting.

Because even if people don't eat those soybeans directly, those genetically modified soybeans will be made into feed and fed to pigs, cows, chickens and ducks.

And these animals will eventually appear on our table in the form of various meat products.

With soilless cultivation, these genetically modified foods can be avoided as much as possible.

Because of soilless cultivation, pests and diseases can be naturally isolated.

Because the eggs of the pests are basically hidden in the soil, it is difficult to kill them.

It breaks the ground every summer and damages crops.

At this time, farmers have to use a lot of pesticides to kill these pests.

In addition, the same is true for weeds. In order to kill weeds that rob crops of nutrients, farmers will use paraquat, a potent poison.

Although the concentration is not high, and it will volatilize and disperse, it is inevitable that there will be residues.

If people eat too much, they will cause harm to their bodies sooner or later.

And if soilless cultivation is used, there will be no troubles such as weeds robbing nutrients.

People who plant in this way do not need to use pesticides to kill pests and diseases on crops, nor do they need to use paraquat to kill weeds.

And because it is cultivated in a safe warm shed, there is no need to worry about rain and wind and hail, which will cause problems such as lodging of vegetables.

This eliminates the need to use lodging-resistant transgenic seeds.

And because of the fast growth cycle, there is no need to use genetically modified seeds with increased protein content.

Because even if the content of some nutrients in a single product is not high, it is only a medium qualified level.

But relying on the characteristics of short maturity cycle and large output, it can be supplemented by quantity.

And the vegetables and fruits cultivated in this way, as long as they add enough carbon dioxide, so that they can carry out sufficient photosynthesis.

Then such vegetables and fruits will taste very good.

It even tastes better than those grown in soil.

And as long as you add a mature control system to the greenhouse, you can also reduce staffing and greatly improve production efficiency.

Such an industrialized way of thinking to engage in agriculture is the future way out for modern agriculture.

And although this model of industrial agriculture was pioneered by the Israelis and the Japanese.

But where they are, they did not survive and flourish. Instead, due to a series of problems such as labor and other costs, the prices of vegetables and fruits are very expensive.

But in our country, Chen Jianfeng confirmed that this is a very promising industry.

Because first of all, one of our advantages over them is that our country has another large natural market.

With a population of 1.4 billion, this is our natural advantage.

The second is our land. If calculated according to the effective cultivated area per capita, it is not even comparable to Japan.

This has led to the scarcity of land resources in our country.

And because of the special land contract responsibility system, my country's farmland is scattered in the hands of many individual farmers.

There is no way to develop large-scale mechanized planting, so our agriculture has not been mechanized until now.

This has also led to a very low agricultural production efficiency in my country.

However, if we engage in soilless cultivation in greenhouses, then these problems will not exist.

In fact, many rural areas are now facing the problem of large-scale abandonment, that is, farmers find that farming is not profitable, so most of them choose to abandon the land and not cultivate it.

Because one acre of land has to use more and more expenses, which is getting higher and higher.

Because the cost of use has skyrocketed, the cost of fertilizer is a lump sum.

There are also seeds. Now, almost a large number of seeds in our country have to be imported from abroad, which is another sum of money.

The second is water and electricity. Many rural areas have to use machine wells to pump groundwater for irrigation, which is another expense.

And in the summer, weeding, insecticide, and finally picking and harvesting, etc., are all added together.

Converted to the calculation, one acre of special mother will earn about a hundred or ten dollars.

And each farmer has only one mu of land per household, which is still the northern region with relatively more land.

If this were the South, many families would not have an acre of land...

Except the Northeast and Northwest of course…

Then plant an egg?

If you go to the city, even to check the gate of the construction site, you can get one or two thousand a month casually.

If you have the strength, even if you go to the construction site to move bricks, you can make seven or eight thousand a month.

Who still wants to farm?

This has resulted in a large amount of farmland being abandoned...
