What is the soil on the moon? Can you grow things?

Moon soil has a strong killing and carcinogenic effect on mammalian cells. In order to protect astronauts from growing vegetables on the lunar soil, another technology may be needed.

During the implementation of the Apollo moon landing program in the United States, during the return phase of the spacecraft, astronauts should clean up the lunar dust raised on the spacecraft when landing. After returning to the ground, the astronauts also carried out various inspections to ensure that they would not be harmed by lunar dust. Astronauts also complained that the lunar soil was very uncomfortable. When they return to the lander from the lunar surface, a very small amount of lunar dust brought into the spacecraft will cause a feeling similar to pollen allergy. The moon dust particles are very small, as fine as flour, less than 20 microns in diameter, but the surface is rough and sharp, and it is composed of glass, olivine, plagioclase, ilmenite and some silicate rocks.

Based on these characteristics of lunar soil, it is unrealistic to plant crops on the surface of the moon by using lunar soil. Plants need to be taken care of, and lunar soil is harmful to human body. Why take the risk? In space, mankind has a more efficient mode of production. Using soilless culture technology, it can be planted in both vertical and horizontal directions, which can greatly increase the light receiving area of plants and improve the yield. Soilless culture eliminates the limitation of soil, and uses sponges and other materials to absorb nutrients and water as "soil" to fix the roots of plants, and it is not afraid that the moon soil will cause harm to human body.

Just from the elemental composition of the lunar soil, it is no different from the earth, but many compounds in the lunar soil are insoluble and difficult to dissolve in water and are absorbed by plant roots. Without mineral salts, plants will die. Even if you want to grow vegetables with lunar soil, you need special treatment. It may not be cost-effective to use soilless culture technology directly.

Our people are an ancient and hardworking people, and they like farming best. They are a small corner, and they want to cultivate some radish and cabbage, which not only beautifies the environment, but also solves the problem of delicious food.

With fewer and fewer "corners" like cities and rural areas, some people begin to think about the moon.

It is said that the moon was not occupied by Chang 'e, WU GANG and Yutu. As the original legend says, and it is uninhabited land, can it be reclaimed? You can't eat some moon dishes by yourself, but you can make a lot of money by selling them.

But unfortunately, we are too far away from the moon, 380 thousand kilometers, and we can't go by plane. We must take a rocket. Is that dish still edible after tossing and turning? More importantly, I don't know if the soil there can grow vegetables.

Space-time communication believes that vegetables can certainly grow, but there must be several conditions, one is air, the other is heat preservation device, the third is water for irrigation, the fourth is organic transformation, and the fifth is compound fertilizer.

At present, the moon is still barren, and anyone who has the ability can go up and open up wasteland.

However, there is a high vacuum on the moon, which is many times higher than the artificial vacuum on earth. Vacuum can not only provide nutrients for plants, but also extract water from plants, making them highly dehydrated vegetables.

On the moon, the temperature in sunny places is as high as 160 degrees Celsius, and the temperature in shady places without the sun is as low as-180 degrees Celsius. The same land is hot and cold. On the one hand, you can roast mutton kebabs, on the other hand, you can freeze them into ice sculptures, which will break into powder when you touch them.

Third, to have liquid water, the roots of plants need water to absorb nutrients. Although some people say that there is water on the moon, it is only in the permanent shadow of the poles and deep underground, and it is not easy to take it out.

Only the above three can't grow vegetables on the moon.

Because there is no life on the moon, its lunar soil is also primitive, but this primitive ecology is not "born", but the original rock powder formed by meteorites hitting the moon rock, and there is no organic matter in it.

I'm afraid it's not a day's work to turn the lunar soil into organic soil, because the earth's soil was formed after billions of years of existence of living things, and there are all kinds of living things in it, which makes the soil full of vitality and vitality, while the lunar soil is just a pile of dead soil and lifeless.

This requires organic transformation. It is not enough to rely solely on the excrement of these immigrants who go to agriculture. It is necessary to carry out scientific transformation through organic matter brought up on the earth.

Then all kinds of trace elements needed for plant growth can be solved by compound fertilizer transported by spacecraft. It seems that this is the easiest solution, but the cost is quite high.

If there is a way to solve the above problems, it should be natural to plant plants on the moon.

The gravity of the moon is only one-sixth of that of the earth, that is to say, the force that plants are pulled up by gravity is only one-sixth of that of the earth, and the same seeds may grow taller and stronger. It seems that there is no problem with a bumper harvest, but it is difficult to discuss theoretically whether it tastes the same.

So what is the "substance" of the lunar soil? What's the difference between them and the soil of the earth? In other words, what is the composition of the lunar soil?

The analysis of the lunar soil brought back by the moon landing shows that the lunar dust is rich in metal elements such as iron, calcium, magnesium, cerium, rhenium and zinc, and also rich in silicon, aluminum, potassium, barium, lithium, rubidium, zirconium, hafnium and rare earth elements, as well as silver, bromine, cadmium, gallium, germanium, mercury, indium, lead, antimony and tellurium.

In fact, the elements found on the moon also exist on the earth, and the elements on the earth also exist on the moon. Perhaps it is the ignorance of communication between time and space, and no report shows that any element is different from the moon. However, there is a big difference in the element content between the earth and the moon. Some elements exist naturally on the moon, such as cerium, which is artificially synthesized on the earth.

There are some rare elements with very high utilization value on the moon, which are much higher than those on the earth.

For example, helium -3, which is most interesting to human beings, is considered to be the safest and most efficient fuel for nuclear fusion power generation. The whole earth's reserves are only 500 kilograms, while the moon's reserves reach1000-5 million tons, which can meet the needs of human use 10000.

But it will not be used until nuclear fusion power generation is commercialized and the ability of human beings to develop and transport lunar mineral resources is mature.

To sum up, if the soil of the moon can solve some of the above problems, it can completely open up wasteland for farming. It's just that those problems are difficult to solve. It was not until man established a space base on the moon that some planting experiments could be carried out in a sealed moon city. It may take decades to achieve this goal.

However, it is very likely that cultivated land will never be cultivated on the moon. The biggest possibility for mankind is to build a factory to extract rare elements on it, and extract useful elements from lunar soil and lunar rocks for the benefit of mankind.

The earth on the moon was made by ancient gods, and there were people in China. No matter whether it is potato or sweet potato, cabbage or radish, any crop can be planted, at least there are osmanthus trees in Wugang.

The loose soil layer on the surface of the moon is called lunar soil, which is mainly formed by the impact, crushing and fragmentation caused by the temperature difference of meteorites. The lunar soil is mainly composed of olivine, plagioclase, ilmenite and some silicate rocks. Lunar soil is produced by meteorite impact, and its microstructure is formed by long-term space weathering (solar wind, cosmic rays, etc.). ).

Water ice also exists in some dark areas of the moon. JAXA of Japan reported in Science that water ice was found in the shadow area of the South Pole of the Moon. Lunar water ice plays an important role in lunar development and subsequent production and life. It can be used as drinking or planting water, and can also provide fuel and oxygen supply by separating hydrogen and oxygen through hydropower.

With soil and water, there is a lack of various nutrients below. Jin Kela and other compound fertilizers are essential. Through future exploration, we can imagine planting crops on the moon. In microgravity, maybe a cabbage can grow to the height of a person. When it can be planted on the moon, we will contract the land.

Welcome comments and pay attention to the quantum laboratory.

Nothing can be planted. . The soil on the moon is lunar soil.

The particles of lunar soil are very fine, generally ranging in diameter from 30 microns to 1 mm, and the composition is very complicated.

Including meteorite components, rare gases (helium -3, neon -20, argon -38, etc. ) produced by solar wind and cosmic rays, as well as elements such as silicon, aluminum, potassium, silver, bromine, mercury, lead and tin.

There are some naturally occurring metal elements on the moon, which are rare on the earth or can only be obtained by artificial synthesis. For example, metallic titanium is a rare element on the earth. In addition, metallic cerium can only be obtained artificially on the earth.

Although the lunar soil contains many elements, many elements are not necessarily a good thing. If it is directly used to grow things, it still won't work. . . . . .

First of all, there is a lack of ingredients needed by plants, such as the most important water needed by plants on earth, which is not found in the lunar soil. In addition, mineral salts really needed for plant growth, such as nitrogen, phosphorus and carbon, are also lacking in lunar soil. Therefore, it is impossible to plant flowers and vegetables directly in the lunar soil.

However, the elements in the lunar soil are still very useful for the development of other technologies.

For example, helium -3 mentioned just now can be used for nuclear fusion and can provide a lot of clean energy. Metal titanium can be used in the space shuttle, and there is also a lot of research space.

The soil on the moon is called lunar soil, which is very different from the soil on the earth and may be more like sand in the desert.

The soil on the earth is formed by oxidation, humidity, weathering, biology and other factors, but there is basically no atmosphere on the moon, so there is no need to worry about wind, oxygen and oxidation. There is basically no water vapor, humidity and biology on the moon, so there is no biological action to produce decent soil.

So what's on the moon? There are fragments of small celestial bodies (such as meteorites), cosmic ray bombardment, and particles in the solar wind. In terms of chemical composition, there are quite a lot of silica, or glass particles, some metal elements, and helium 3, which can be used as fuel for nuclear fusion. With the passage of time, the particles of lunar soil will become smaller and smaller, and the particularly fine particles are also called lunar dust.

It is not difficult to see that it is not difficult to grow crops directly on the lunar soil. On the one hand, lunar soil may be difficult to keep the water needed by plants, and on the other hand, it lacks the nutrients needed for plant growth, so lunar soil basically only has the function of fixing plant roots, and even this fixing function is not available everywhere. In some places, the lunar soil is several meters thick, but in some places it is only about one centimeter, which is quite thin by the standards of the earth.

Because the word "soil" in the soil has the connotation of plant growth, and the soil on the moon does not have this function, some people even object to calling the soil on the moon lunar soil.

The soil on the moon, commonly known as "lunar soil", is a kind of powdery rock, mainly composed of lunar rock debris, powder, breccia and molten glass, most of which are between 30 microns and 1 mm, and feel like flour.

Of course, if you want to plant land on the moon, you have to see if the moon rocks can be used. Generally speaking, there are three main kinds of rocks on the moon. First, there are moon sea basalts rich in iron and titanium; The second is plagioclase, which is rich in potassium, rare earth and phosphorus, mainly distributed in the lunar highlands; The third kind starts from the lunar soil. Moon rocks contain all the elements and about 60 minerals on the earth, and there are 6 minerals that are not on the earth. The ingredients are ready, and there seems to be nothing missing. In fact, everything is missing. All kinds of mineral elements such as nitrogen, phosphorus and potassium needed for plant growth are not available and cannot be directly absorbed.

Therefore, if we want to use lunar soil to reclaim land on the moon, we must transform it. Just like the earth's soil, it is composed of minerals, organic matter, water, air and microorganisms. Only with fertility can plants grow. You can refer to the process of Mark transforming the Martian soil in order to grow potatoes in "Mars Rescue".

The University of Vakhnin Genn in the Netherlands made a similar attempt on 20 13, trying to plant plants in soil similar to the Moon and Mars, hoping to help future pioneers grow their own crops in space. Of course, they can't get the real soil of the moon and Mars. But with the help of NASA, they replaced the lunar soil with soil from Arizona desert and the crimson soil on the surface of Mars with soil from a volcano in Hawaii. The experiment has achieved some success, and plants have successfully grown in improved soil. Of course, this experiment is flawed, because the experiment was carried out in a sterile environment on the earth, and the researchers only considered the content of nutrients in the soil.

Therefore, it is not easy to farm on the moon without establishing a permanent lunar base.

The chemical composition of the soil on the moon is very different from that on the earth. After analyzing the samples brought back by astronauts from the moon, we can know that the soil on the moon contains a lot of rare metals.

There is no atmosphere on the moon, so the lunar soil is not made of weathered rocks. There are natural mineral particles such as iron, gold, silver and aluminum in the lunar soil, compounds containing a small amount of tin and copper impurities, and a small amount of mineral particles such as Thai baht. Therefore, the lunar soil contains a lot of heavy metals.

The soil on the moon is powdery, similar to the desert on the earth, but the color of the soil on the moon is different from the sand on the earth. The soil on the moon looks gray, because the minerals in the soil on the moon are different from the sand on the earth, which leads to different reflected light.

It is found that the lunar soil contains a lot of helium 3, which is an important raw material for nuclear fusion reaction. This kind of fusion will not produce extra neutrons, so it is safe and pollution-free. Moreover, according to calculations, the content of helium 3 on the moon is dozens of times that on the earth. If human beings have the ability to extract helium 3 from the soil on the moon in the future, and then they master the controlled nuclear fusion, there will be no more energy crisis on the earth. In addition, the moon also contains a lot of metallic titanium, which is an important aerospace material.

The soil on the moon can be said to be very valuable, but the soil on the moon can't grow plants. The first reason is that there is no water in the soil on the moon. How can plants survive as long as there is no water? Of course, is it feasible to take the soil on the moon to the earth to grow plants? No one has ever done this. Simply adding water is definitely not enough. There are not even bacteria in the lunar soil. Plants can still be planted if they are transformed.

Lunar soil refers to the unique soil on the moon.

There are natural mineral particles such as iron, gold, silver, lead, zinc, copper, antimony and rhenium in the lunar soil. Most of them are glassy silica, which is caused by meteors hitting the moon. For billions of years, constant collisions have melted the surface soil of the moon into glass and shattered it into tiny pieces.

As a scientist pointed out, the moon is covered with glass. Analysis proves that this glassy substance is not produced by the impact of a huge meteorite. Some scientists think it is the result of the solar explosion and some kind of miniature nova state.

Scientists also found a strange phenomenon: there are pure iron particles on the surface of the moon, which have not rusted after being placed on the earth for 7 years. In the scientific community, pure iron that does not rust is unheard of!

After analysis, it is found that the soil samples contain a lot of rare metal titanium (used in supersonic jets and spacecraft). Other hard metals, such as zirconium, iridium and beryllium, are also abundant. Scientists are puzzled that these metals will only mix with rocks at a very high temperature of about 4500 degrees Fahrenheit.

Suspect that the moon is a spaceship from outer space! Or a large alien spacecraft crashed into the moon due to a malfunction! Then the moon was captured by the earth!

The moon is much older than the earth! Can plants grow in the lunar soil? Think for yourself, okay? Can't!

Scientists in China have studied the detection data of the "Yutu" lunar rover and solved some mysteries of lunar soil. Jade Rabbit landed in the rainy basin of the moon, where the lunar soil is rich in helium -3 and hydrogen. It is also obtained by spectral analysis technology that lunar soil contains 12 elements such as magnesium, aluminum, silicon, calcium, titanium, potassium, chromium, iron, strontium, yttrium, zirconium and niobium, and the last four are trace elements. The lunar soil itself cannot be planted, but Chinese and foreign scientists have been studying how to transform it. The researchers found that adding different bacteria to the lunar soil can improve the lunar soil so that the earth plants can grow there. Planting the moon is not a fantasy, it will come true one day.

Answer: The dust on the surface of the moon is split after hundreds of millions of years of solar radiation, and its composition contains substances that are difficult to exist and synthesize on our earth. I have read the relevant reports, but I can't remember the name. It is a valuable energy substance. When people have it, they don't have to worry about energy. I hope that mankind can realize this dream one day and benefit us to make an empty earth. Thank you!
