This is a manifestation of soil salinization. It belongs to the long-term large-scale application of nitrogen, phosphorus and potassium. The soil produces halophilic microorganisms, which act on the soil organic matter for a long time to precipitate iron and aluminum ions, which makes the soil appear brick red. This is neither moss nor moss. , Nor is it a biological fungus. To improve this type of soil, vegetable growers should plow the ground deeply, irrigate the soil with flooding, and use water to compress salt when changing stubble; on the basis of reducing the amount of nitrogen, phosphorus and potassium applied, increase the application of organic fertilizer and biological bacterial fertilizer conditioning. After a quarter of conditioning, the soil brick red problem should be effectively improved.
