How to get the soil for potted plants, how to get the soil for potted plants, how to get the soil fo

One. Potting soil concept.

Potting soil is a mixture of native soil (sandy loam) with organic matter and chemical fertilizers for potting.

Second, the preparation principle of potting soil.

1. It has excellent physical and chemical properties;

2. Choose cheap and easy-to-obtain mixed materials: (**Low, high effective nutrients, reusable, easy to mix, good physical properties.)

3. The texture is moderate and the specific gravity is small.

4. It is not easy to be infected with pests and diseases.

3. Material selection of potting soil.

In addition to soil, common materials are: sawdust, bark, peat, vermiculite, perlite, rice husk, etc., which can also be prepared without soil and peat.

Such as: peat + sand.

Peat + wood chips.

Peat + vermiculite or perlite, etc.

There are many ways to change the acidity and alkalinity of the soil: if the acidity is too high, some lime powder or plant ash can be appropriately mixed into the potting soil; To reduce alkalinity, an appropriate amount of sulfur, aluminum sulfate, ferrous sulfate, and colonization fertilizer can be added. For a small amount of cultured soil, the mixing ratio of rotten leaves or peat can be increased.

For example, in order to meet the needs of flowers that like acidic soil, potted flowers can be watered with 1:50 aqueous solution of aluminum sulfate (alum) or 1:200 aqueous solution of ferrous sulfate; In addition, the application of sulfur powder is very effective, but the effect is short-lived, and it needs to be applied every 7 to 10 days.

1. The materials for the preparation of culture soil are very type to dig, there are the following types: humus soil: put the fallen leaves, dead grass, straw, etc., in the pit, a layer of leaves, a layer of soil, remove some manure, multi-layer accumulation, external capping with 10 cm thick soil, after more than half a year of fermentation and decay, soil and fertilizer fusion, sieve can be used.

It's better to have an outdoor space, it doesn't taste very good. ）

2. Mountain soil: It is a natural humus soil, which is formed by the natural accumulation of fallen leaves of trees in mountainous areas, rich in humus, as long as it is mixed with a small amount of garden soil and thin human feces, it can be used after being fully decomposed. (It has good water permeability and is suitable for the planting of various common flowers.) ）

3. Manure soil: Pig and cow dung, chicken and duck manure, etc., mixed with garden soil and weeds, piled up, and watered thoroughly. The compost is sealed with thin mud around it, so that it can be fully fermented and decomposed, and after it is decomposed, the compost is spread out and dried, and the impurities are screened out, and stored for later use.

The fertilizer is better, suitable for planting jasmine fertilizer-loving flowers and plants. ）

4. Pond mud: Dig up the sludge in the river pond and make it into cake pieces, which are dried and collected for later use. When used, it is crushed into particles of different sizes, generally the size of soybeans or broad beans.

The advantage of pond mud is that it has more fertilizer and good drainage performance. (The disadvantage is that the soil is relatively cool, and the seeds do not germinate easily.) ）

5. Rent rock and soil in front of the garden: It is the surface mature loam soil of the vegetable garden, orchard and bamboo garden, which is loose, fertile, and has good permeability, which is suitable for the growth of most flowers.

6. Bone meal: a commercial fertilizer made from animal miscellaneous bones. Household flowers can be made by fermentation of broken bones or poultry hooves and feathers, which contain a large amount of phosphate fertilizer. (Can be used as fertilizer for flowering plants.) ）

7. Flower growers can determine the proportion of culture soil according to the above materials, and then according to the types of flowers and its different requirements for soil in different growth and development stages, and prepare suitable flower soil.

Methods of making soil for planting flowers: acidic soil, alkaline soil, succulent soil.

1. Acidic soil

For acid-loving flowers, the pH of the soil should be lower than 7, which is more conducive to the growth of the plant, otherwise it will cause it to yellow, affecting its health and beauty. Usually the slag should be prepared with humus, peat, wood chips and bone meal, and the ratio of the four is 4:4

1:1, with good soil suitable for planting camellia, rhododendron, gardenia and most of the green plants.

2. Alkaline soil

There are not many plants that like alkaline soil, and the common ones are pomegranate, oleander, hibiscus, cactus, etc., and the soil of these plants is different from the above. Usually river sand, garden soil, humus and gravel are used, according to 4:3

The 2:1 ratio is mixed to provide a good environment for them to grow.

3. Succulent soil

Succulent soil and common plants are different, this plant has high requirements for soil drainage, usually with peat soil, sand and granular soil mixture, it should be noted that the ratio of seedlings and adult soil is different, seedling period, the ratio of the three is 3:1:1, and the adult period is 1:

A 1:1 soil blend is better.

Notes:

The potting soil is seriously alkalized, and when watering and fertilizing the flowers, the potting soil will not absorb it, and the root system will naturally not absorb it. Many flower friends in the pot soil after the compaction, do not find in time, every watering, water is accumulated on the surface or along the crack of the pot wall and soil directly out, the rhizome of flowers is difficult to absorb water and nutrients in time, the light growth becomes weak, there is a dry tip, yellow leaves phenomenon, heavy is dead.

Try to avoid changing the soil of flowers in summer and winter, spring and autumn are the vigorous growth period of most flowers, and summer and winter flowers will generally enter dormancy, repot flowers and plants, to choose in its growth period, in order to let it be affected by the least impact, quickly serve the pot.

There are many kinds of potted soil, mainly humus soil, garden soil, river sand, peaty soil, etc. The humus soil is rich in nutrients, the soil is soft, and the drainage is good, so when the garden soil is used as the potting soil, it is necessary to mix fertilizer into it. Sand needs to be mixed with other soils, and peaty soil is more suitable for acid-loving plants such as yueji.

1. Humus

Compared with ground planting, potted plants have less space and poor permeability, so the soil needs to be drained and breathable, so as to facilitate the growth of plants. Many people don't know what kind of soil is used for potting, and the soil for potting is first of all humus, which is rich in nutrients, soft soil, and good drainage, which is suitable for the survival of potted plants.

2. Garden soil

Garden soil is the surface soil of the vegetable garden or garden, which contains the basic nutrients required for plant growth, and is loose and breathable, is the best type of potted soil, when using garden soil to breed potted plants, it needs to be doped with fertilizer, such as rotting farmhouse fertilizer, nitrogen, phosphorus and potassium compound fertilizer, etc., in order to provide sufficient nutrition for plant growth.

3. River sand

Large particles of river sand have good drainage and air permeability, which can promote the growth of plants, but there are no nutrients required for plant growth in river sand, so it also needs to be mixed with other soils, and river sand can be mixed with garden soil or other humus soil, which can accelerate the growth of plants while draining and breathing.

4. Peaty soil

Peaty soil is the residual soil of unfinished decomposition of swamp plants, which is rich in nutrients and minerals required for plant growth, and is weakly acidic soil, with soft texture and good drainage and air permeability, which is more suitable for planting acid-loving plants such as Yueji and Camellia sinensis.
