Seven methods of making Garden cultivated soil

There are many materials suitable for the preparation of culture soil, and the following are commonly used at present.

1. Plain sandy soil

Most of them are taken from the beach. The drainage performance is good, but it has no fertility, so it is often used to mix with other culture materials to facilitate drainage.

Culture soil: determination and change of pH of culture soil

2. Garden soil

Soil taken from the surface of a vegetable garden, orchard, etc. It contains certain humus and has good physical properties, so it is often used as the basic material of most cultured soils.

3. Rotten leaf soil

It is made of fallen leaves, withered grass, etc. It is one of the main materials for preparing culture soil because of its high content of humus, strong water retention and good permeability.

4. Mountain mud

There are two kinds of black mountain mud and Huangshan mud. It is formed by the long-term accumulation of fallen leaves of trees in the mountains. Black hill mud is acidic and contains more humus, while Huangshan mud is also acidic and contains less humus.

5. Peat soil

It is carbonized from peat moss. Due to the different stages of formation, it can be divided into brown peat and black peat. Brown peat is rich in organic matter and shows acidic reaction, while black peat contains more minerals and less organic matter, showing slightly acidic or neutral reaction.

6. Rice chaff ash

It is ash made from rice husk after combustion, slightly alkaline, containing potassium, good drainage and air permeability.

7. Stable manure soil

It is made of animal faeces, fallen leaves and other materials mixed with human garden soil, sewage and other accumulation and retting, which has rich fertility. In addition, there are pond mud, river mud, coniferous soil, turf soil, rotten sawdust, vermiculite, perlite and so on, which are good materials for preparing culture soil.

The preparation of culture soil should be flexibly mastered according to the growth habits of flowers, the properties of culture soil materials and local conditions. For general potted flowers, the commonly used proportion of culture soil is rotten leaf soil (or peat soil): garden soil: River sand: bone meal = 35RV 30vet 5, or rotten leaf soil (or peat soil), plain noodle sand soil, rotten organic fertilizer, calcium superphosphate and so on. After sieving, use. Most of the above culture soil is neutral or slightly acidic, which is suitable for most flowers. Flowers and trees used for cultivating acidic soil such as camellia and rhododendron can be mixed with about 0.2% sulfur powder; flowers such as cactus can be cultivated, and about 10% of the wall skin soil peeled off from the lime wall can be added.

Culture soil: self-made method of ordinary culture soil

Due to the different requirements for nutrients, acid and alkali resistance, drainage and ventilation, and the proportion of preparation is also different, the basic requirements for cultivated soil should be based on the following principles:

1. Have appropriate proportion of nutrients, including nitrogen, phosphorus, potassium and other trace elements.

2. It is required to be loose, good ventilation and good drainage.

3. Diseases, pests and other harmful substances that do not harm the growth of flowers and trees, such as insect pupae.

4. Remove grass roots, gravel and other sundries, sieve and carry out general disinfection, such as exposure in the sun or heating and steaming.
