You can also grind it open on the ground to reveal the white seed inside, but be careful not to destroy the seed. - Soak the seeds in warm water of about 30 degrees Celsius for 3 - 5 days, change the warm water once a day, and place them in a place without strong light to wait for them to germinate; or put the seeds in a warm room, soak them in warm water for 2 - 3 days, and then cut open the inside with a knife (avoid the embryo) to ensure light and water temperature above 15 degrees Celsius. Treat the concave surface of the seeds so that they touch the water surface to promote growth. 3. ** Sowing time **: Sowing can be done all year round, but the temperature in spring is constant, the environment is warm, and there is sufficient light. Sowing in early spring is easier to survive. 4. ** Water temperature management **: The breeding temperature needs to be constant. The temperature in spring and autumn should be suitable. In summer, pay attention to sun protection. In winter, the temperature should not be lower than 5 degrees. 5. ** Light Management **: 2 - 3 hours of light per day, but avoid strong light in summer. 6. ** Fertility Management **: NPK compound fertilizer can be used appropriately.

The soil on the moon was usually composed of lava and rocks from volcanic eruptions on the surface of the moon. This soil was called moonstone, and it was a material mainly composed of silicates and agglomerates. Due to the lack of water resources and suitable temperature conditions on Earth, it may not be feasible to grow plants on the Moon. However, some plants are adapted to cold environments, such as cacti and succulents. They can survive in extreme environments. If humans could grow some plants on the moon, these plants would need to adapt to the extreme conditions of the moon, such as low light, low temperature and strong winds. This required special breeding techniques to ensure that they could grow and thrive. At the same time, we also need to consider the cost of plant growth and maintenance, as well as how to bring plants back to Earth.

The bleached layer was usually composed of bleached substances, including segregated iron-Mn agglomerations, agglomerations, and patches. The whiteness itself showed the characteristics of the color, such as a tint lower than 2, a moistened lightness greater than 3, a dry lightness greater than 6, and so on.
