1558 The Importance of Gas Fertilizers

This is also discovered by foreign agricultural experts after research and comparison.

And our domestic greenhouses, huh, are too far behind in terms of real scientific research and exploration.

The greenhouses like those in Israel and Japan can be said to be a new type of greenhouse technology explored by large-scale industrial planting.

Soilless cultivation is used, and in our country, most farmers have limited economic strength.

And we also have enough land, so most of them use soil cultivation.

Because of this, our soil cultivation, because there is soil, it can also emit a certain amount of carbon dioxide.

Therefore, crops can still perform corresponding photosynthesis on the second day, but as for the specific effect, it is definitely not as good as crops under the condition of sufficient carbon dioxide.

Because our experts have never specifically analyzed how much carbon dioxide will be required for one acre of crops during the growth stage, specifically at each different stage.

How much organic matter is converted to each gram of carbon dioxide absorbed.

These really hardcore scientific studies have never been our agronomy experts' expertise.

Because it involves a lot of professional chemistry and mathematics knowledge.

And foreign experts, especially Israeli experts, are particularly good at this.

For example, when they were engaged in greenhouse cultivation, they made special calculations.

Green plants need to absorb 1.6 grams of carbon dioxide for each gram of organic matter produced to complete photosynthesis.

The efficiency of absorbing carbon dioxide is 40 times that of other substances. In addition, 90% of the dry matter accumulated in plants comes from photosynthesis.

And one acre of crops, from germination and seedling to finally ripening and bearing fruit, the amount of carbon dioxide required to consume is equivalent to the amount of carbon dioxide contained in 80,000-120,000 cubic meters of air!

This shows the importance of carbon dioxide to the growth of crops.

And most of the carbon dioxide absorbed by each crop will eventually be converted into sugar in the crop.

So when the vegetables and fruits you eat feel bland and tasteless, and you will say that this is greenhouse vegetables, you must know that the main reason is that they do not absorb enough carbon dioxide.

Because our greenhouses are generally deducted in winter, and our farmers deduct greenhouses to grow vegetables and fruits.

They tend to see keeping warm as their first priority because they think that if the weather is too cold, the vegetables will freeze to death.

Therefore, the greenhouse is often tightly buckled, and even when the weather is cold, a stove will be ignited in the greenhouse to heat up the greenhouse.

But do not pay attention to the ventilation in the greenhouse.

When the sun is the best every day and the photosynthesis in the greenhouse is the most vigorous, the plants will face a shortage of carbon dioxide.

Over time, vegetables and fruits will suffer from nutritional deficiencies and grow very thin.

At this time, farmers will think that it is a lack of nutrients, and then desperately use chemical fertilizers and even leavening agents.

The end result is that the vegetables and fruits in the greenhouse swelled up rapidly and looked ripe, but the taste was far worse than that of the naturally ripe fruits and vegetables.

And compared with foreign greenhouse fruits and vegetables, the taste is even worse.

Once our agricultural experts have also visited foreign countries.

I just want to understand why other people's greenhouse vegetables are cultivated without soil, but after they are grown, the taste is not only not bad, but even better than our soil cultivation?

At first, we just focused our attention on other people's nutrient solution.

It is believed that there is a mystery in the nutrient solution specially used for soilless cultivation.

But we didn't know it until the last few years, after the Internet pandemic.

It turns out that this group of foreigners from Te Niang is too ghostly. They will replenish carbon dioxide to the green crops in the greenhouse every day when the sun is at its best at noon!

They will adjust the carbon dioxide concentration in the greenhouse from time to time according to climate changes, such as sunny and cloudy days, and the sufficiency of early sunshine.

At each time period and each temperature, the carbon dioxide concentration in the greenhouse is guaranteed to be different, so as to ensure that the crops can obtain sufficient nutrient absorption.

This allows crops to complete photosynthesis in optimal conditions, synthesizing as much sugar and dry matter as possible.

In this way, people's greenhouse crops not only grow large and sell well, but the most important thing is that they taste very good.

This is the magic of supplementing carbon dioxide!

And this is what our 'experts' have only known about in recent years!

It turns out that greenhouse vegetables can also be grown like this!

It turns out that this is the real high-tech planting!

And this kind of planting idea also provides a solid foundation for us to carry out large-scale industrial agriculture in the future.

In fact, those large agricultural companies in the United States have already put forward such an idea.

That is, they want to build large-scale agricultural planting ships, at least hundreds of thousands of tons, and large ones in the millions.

Then go straight to the open sea for soilless cultivation.

Especially when the ship is driven near the equator, where there is sufficient sunshine, and because it is at sea, several freshwater supply centers can be specially built.

What do you mean, it is to build a few boats specially, and then follow the clouds according to the weather forecast.

Wherever the rain falls on the sea, they follow wherever they go, collecting rainwater constantly, and then sending it back to the planting boat.

As for the rest, it is simple, the means of production are available, and the rest is nothing more than the problem of the nutrient solution of soilless cultivation.

This is also easy for those large companies to deploy.

Xiao Feng had also seen such a plan, and even after learning about the ideas of these foreign devils, he had to admire how these guys were really open-minded.

Can think of such a way.

However, the reason why it has not been implemented is mainly because it is not necessary at present.

It is the Americans who made this plan, and many people know that the United States is the world's most powerful technological country, but they don't know that they are also the world's most powerful agricultural country.

The degree of agricultural development in the United States, if you take a closer look at it, will definitely make you stunned.

The annual crop output of the United States alone can feed a quarter of the world's population.

Up to now, people have used a very extravagant crop rotation method, that is, one year of planting and one year of drought to maintain the land's strength.

Even so, people can still produce so many food crops, so there is no need to go to sea farms at all.

Their plan is that if the world's population increases to 10 billion, the land on the earth can no longer bear the problem of feeding so many people, and they will choose such a method to solve the problem of eating.

But now it seems that even if there is a real population of 10 billion, it will definitely be able to feed.

After all, there is still a lot of uncultivated land over there.

When it comes to waste of land, the Americans say No. 2, and the bear definitely dares to say that he is No. 1 in the world.

When a bear grows, it is absolutely a matter of sowing a handful of seeds and then leaving it alone until the autumn comes to harvest.

Anyway, there is too much land for people to manage.

What kind of intensive farming does not exist at all.

If there is not enough food, then eat meat, anyway, there is enough meat over there...

If there are not enough breeding, then go hunting in the mountains.

There are so many animals in the Siberian jungle.

Moreover, in the rivers and lakes in the Maoxiong realm, there are countless fish.

And people basically do not eat freshwater fish, because they have spines, it is too troublesome to eat.

Just so capricious...

So let alone increase the world population to 10 billion, even if it increases to 15 billion.

As long as 70% of the available farmland in the United States and Maoxiong is developed and utilized, the world's population can already be fed.

But they would never do that!

why? Because if you do that, the grain will not be able to sell for a price.

So you see now, even though Americans also know, a quarter of the world's population goes hungry every day.

But do you see them keeping food prices down?

What can't be sold is better piled up in the ground and composted to rot than given to those who are starving.

Going farther, let’s continue to talk about the role of carbon dioxide in the agricultural field.

It was only after 2010 that our "experts" in agronomy learned about the secrets of greenhouse cultivation abroad.

It turns out that people's vegetables and fruits do not need to use bulking agents, nor do they need to be fertilized indiscriminately.

The real reason is to add enough carbon dioxide in the greenhouse.

However, this supplement of carbon dioxide is not a random supplement, but should always be adjusted according to sunlight and temperature.

This requires a complete monitoring operating system.

And again, we're sorely lacking in this regard.

Moreover, our farmers have to go to the rural credit cooperatives to borrow money if they deduct a greenhouse.

What carbon dioxide control system did you ask him to spend tens of thousands of dollars to install in the greenhouse?

Isn't this a few calves?

And even if you tell him that with this system installed, the vegetables and fruits grown will look good and taste good, do you think they will accept it?

The peasants will teach you a lesson with peasant cunning!

Installing such a system would cost tens of thousands! How much did they pay for a shed of vegetables?

And obviously, top dressing and the use of bulking agents can make vegetables and fruits grow in size. As for the taste, is it good?

Oh, it's my bird business? Anyway, as long as the vegetable is the vegetable and the fruit is the fruit, it looks right.

As for the taste, hehe, for most people in China who have just gotten rid of the problem of food and clothing, some food is already good.

After all, most people are not rich enough to pursue the quality of life stage...

this is the truth!

And for farmers, how much does it cost to use bulking agents and fertilizers?

If you install a system to monitor carbon dioxide and adjust carbon dioxide from time to time, the cost is obviously much higher than the use of leavening agents and fertilizers.

Therefore, when most of our people are not rich enough to pursue the quality of life, this gas fertilizer system cannot be popularized in China.

But for Xiao Feng, this thing is much more useful.

Because he now sells terminals, in terms of demand for raw materials, that's almost limitless.

And his famous chefs have requirements for ingredients...
