What is the preparation method of nutrient soil?

In daily life, people often plant some potted plants at home. There are many types of potted plants, such as some succulents. Planting them at home can purify the air, help regulate people's emotions, add more fun to life, and so on. When planting potted plants, nutrient soil is needed. Maybe many people don’t know where the nutrient soil comes from, so here is how to prepare it.

How to prepare the cultivation soil:

It should be flexibly controlled according to the growth habits of flowers, the properties of the culture soil materials and local conditions. For general potted flowers, the commonly used culture soil preparation ratio is leaf mold (or peat soil): garden soil: river sand: bone meal = 35:30:30:5, or leaf mold (or peat soil), plain sandy soil, decomposed organic fertilizer, superphosphate, etc., mixed in the ratio of 5:3.5:1:0.5 and sieved before use. The above-mentioned culture soils are mostly neutral or slightly acidic, suitable for most flowers. For cultivating flowers and trees that prefer acidic soil, such as camellia and azalea, about 0.2% sulfur powder can be added. For cultivating flowers such as cactus, about 10% of wall soil peeled off from lime walls can be added.

Preparation method of nutrient soil

▲The ratio of mountain mud: garden soil: humus: rice husk ash (wood ash) is 2:2:1:1, or the ratio of garden soil: compost: river sand: wood ash is 4:4:2:1. This is a light fertilizer soil, suitable for general potted flowers, such as poinsettia, chrysanthemum, begonia, asparagus fern, cineraria, geranium, etc.

▲The ratio of mountain mud: humus: garden soil is 1:1:4. This is a heavy fertilizer soil, suitable for acidic flowers such as Milan, kumquat, jasmine, gardenia, etc.

▲Garden soil: mountain mud: river sand is equal to 1:2:1 or garden soil: wood ash is equal to 2:1, suitable for alkaline flowers such as cactus, prickly pear, jewel flower, etc.

▲Peat soil: perlite: river sand: vermiculite = 2:1:1:1 is suitable for succulents, with more particles and strong air permeability.

▲Garden soil: rice husk ash is equal to 1:1 or river sand alone can be used for cuttings or planting.

Note! Disinfection of potting soil:

Generally, the culture soil for potted plants does not need special disinfection, as long as it is exposed to sunlight. This is because, on the one hand, the flowers themselves have a certain resistance; on the other hand, the soil contains a large number of microorganisms, whose activities gradually decompose many nutrients to maintain soil fertility, which is conducive to the growth of flowers and trees. High temperature disinfection or disinfection with chemicals can also be used, but the microorganisms are killed and the organic matter in the soil cannot be decomposed, which is not conducive to the absorption of flowers and trees. The culture soil used for cuttings and sowing must be strictly disinfected, because pathogens can easily invade the body of flowers and trees through the wounds of the cuttings, causing rot and affecting survival. For sowing, the newly born buds have very weak resistance and microorganisms often cause them to mold.

Commonly used soil disinfection methods: The boiling disinfection method is to put the prepared culture soil into an appropriate container and boil it for 30 minutes. The chemical disinfection method mainly uses formalin for disinfection. Evenly sprinkle 4 to 5 ml of 40% formalin solution per liter of culture soil, and then seal it to prevent air leakage. Leave it for 2 days before opening.
