Seedlings require soft, breathable, well-drained, nutrient-rich soil.
1. Types and characteristics of seedling soil
1. Soil: Generally composed of sand, silt, clay, organic matter, etc., soil has poor permeability, can retain water and fertilizer, and has good heat preservation effect.
2. Sand soil: The sand particles are larger and have good ventilation. The moisture and nutrients in the soil are lost quickly and need to be nourished and improved.
3. Clay: Soil particles are highly sticky and have poor drainage. If fertilizers with sand and organic matter can be improved or added, it can be transformed into soil suitable for flower growth.
4. Sandy soil: A mixed soil of sand and loam. The permeability and drainage of sandy loam are better than that of sandy loam.
5. Peat soil: It is composed of concentrated organic matter, has no fertility, and is not suitable for long-term cultivation.
2. Characteristics of seedling soil
1. Soft: The seedling soil must be kept soft so that the seeds can grow easily.
2. Breathable: The soil must be breathable so that the seeds can absorb water and nutrients.
3. Good drainage: In poorly drained soil, seeds are prone to mold and rot. Soil that can drain quickly is needed.
4. Rich in nutrients: The nursery soil must be rich in nutrients and able to provide the nutrients needed by the seeds.
3. Preparation of seedling soil
1. First purchase a certain amount of peat soil or gardening soil;
2. Mix peat soil or garden soil and leaf humus soil at a ratio of 1:1, mix evenly and place into a cultivation tray.
3. Add an appropriate amount of chemical fertilizer to the mixed soil to increase soil fertility.
4. Carry out soil disinfection to ensure that the soil is free of harmless bacteria, insects and weeds, and at the same time enhance the permeability of the soil.
4. Precautions for nursery soil
1. The soil for raising seedlings should be fresh and free of impurities;
2. During long-term use of the soil, it is necessary to replace or add new fertilizing substances in time;
3. When irrigating, pay attention to controlling the amount of water appropriately to avoid affecting the softness, air permeability and drainage of the soil.
The seedling raising process requires suitable soil. Different types of soil have different characteristics. Choosing the right seedling raising soil can ensure the healthy growth of seeds. When making seedling soil, you need to pay attention to disinfection, fertilization and other steps. The addition and mixing of organic matter can effectively improve the fertility and permeability of the soil.
