There are many kinds of flowers and different growth habits. Cultured soils should be formulated according to the growth habits of the flowers and the nature of the materials. Compost soil: using dry branches, leaves, grass, peels, feces, hair bones, viscera, etc. as raw materials, together with old pots, furnace ash, and garden soil, piled together, poured into the livestock manure, and finally in the surrounding area. Covered with garden soil. After more than three years of storage, it is fermented and rotted, and then smashed and sieved. This is compost soil. Adjusting soil pH: Most flowers grow well in neutral, acidic (pH 5.5-7.0) soils, especially in flowers that are hi acidic soils, such as orchids, camellia, azaleas, gardenia, mirabelle, sweet-scented osmanthus, broad magnolia, etc. Suitable for growth in soil with a pH of 5.0-6.0. If the acidity is too high, some lime powder or ash may be properly mixed in the potting earth; if the alkalinity is reduced, appropriate amounts of sulfur, ferrous sulfate, humic fertilizer and the like may be added. Soil disinfection: The commonly used methods of soil disinfection include steam sterilization and pharmaceutical sterilization. Steam sterilization is widely used in the cultivation of substrates. The prepared culture medium is placed in a suitable container and sterilized in a pot. This method is limited to the application of small-scale cultivation of a small amount of soil. In addition, steam can also be introduced into the soil for disinfection.
