Problems solved by technology

[0003] There is a formula for simulating Martian soil in the prior art (Reference 1: Kevin M.Cannona, DanielT.BrittaTrent, M.SmithbRalphF.Fritscheb, Daniel Batcheldor, Mars global simulantMGS-1: A Rocknest-based open standard for basaltic martian regolith simulants , Icaraus, 317, 470-578, 2019), the formula is generally made for a specific Mars collection point, so there are many types of raw materials in the formula, some ingredients are not easy to obtain, the cost is high, and the preparation method is complicated

Embodiment 1

[0026] Embodiment 1 prepares 100 kilograms of simulated Martian soil

[0027] Prepare 20 kg of ultramafic volcanic lava, or 20 kg of mafic volcanic lava. Among them, those with a particle diameter of more than one millimeter account for no less than 20% of the total weight. 20 kg of albite raw ore is selected, of which the particle size of more than one millimeter accounts for no less than 20% of the total weight. Select 15 kg each of diopside raw ore, forsterite raw ore and quartz stone. Among them, those with a particle size of more than one millimeter account for no less than 15% of the total weight. Choose 10 kg of calcite raw ore. Among them, those with a particle size of more than one millimeter account for no less than 20% of the total weight. Prepare 2 kg each of hematite, magnetite and anhydrite. Among them, those with a particle size of more than one millimeter account for no less than 20% of the total weight. Prepare 4 kg of industrial grade anhydrous magnesiu...

Embodiment 2

[0036] Prepare the simulated Martian soil according to the method described in Example 1, the types of raw materials are the same, but the weight parts are different, and the weight parts proportioning is as follows:

[0037] Volcanic lava 15 parts, albite 15 parts, diopside 12 parts, forsterite 12 parts, quartzite 12 parts, calcite 5 parts, anhydrous magnesium sulfate 3 parts, hematite 1 part, magnetite 1 part , 1 part of anhydrite.

Embodiment 3

[0039] Prepare the simulated Martian soil according to the method described in Example 1, the types of raw materials are different, but the parts by weight are different, and the proportioning of parts by weight is as follows:

[0040]Volcanic lava 25 parts, albite 25 parts, diopside 18 parts, forsterite 18 parts, quartzite 18 parts, calcite 10 parts, anhydrous magnesium sulfate 6 parts, hematite 4 parts, magnetite 4 parts , 2 parts of anhydrite.

Abstract

The simulated Mars soil is prepared from the following components in parts by weight: 15 to 25 parts of pelelith, 15 to 25 parts of albite, 12 to 18 parts of diopside, 12 to 18 parts of forsterite, 12 to 18 parts of quartz sand, 5 to 10 parts of calcite, 3 to 6 parts of dehydrated magnesium sulfate, 1 to 4 parts of hematite, 1 to 4 parts of magnetite and 1 to 2 parts of anhydrite. The components of the Mars soil formula are relatively close to the components of Mars soil returned by the America curiosity car, the raw materials are easy to obtain, the cost is low, and the Mars soil formula can be used for research on Mars planet geology or Mars agricultural development in the future.

Description

technical field [0001] The invention belongs to the fields of aerospace, agriculture and scientific research, and in particular relates to a formula for simulating Martian soil and a preparation method thereof. Background technique [0002] Martian soil refers to the detrital material produced by the weathering of Martian rocks. Depending on the particle size, it can also be called Martian sand or Martian debris. The US Viking 1, 2, Curiosity lander and my country's Tianwen Mars rover have landed on the surface of Mars successively and started geological exploration. In contrast, Martian soils have higher iron content than Earth soils, and magnesium sulfates, iron oxides, and carbonates. Among them, the sulfur content of the Martian soil is 100 times that of the earth, while the potassium content is only one-fifth of that of the earth. It lacks active nitrogen and has no organic matter. Universities such as the University of Georgia and the University of Central Florida ha...
