This is a common cultivated soil. It is one of the main raw materials for compounding and cultivating because of frequent fertilization and cultivation, high fertility and good aggregate structure. The surface sandy loam with vegetables or legumes is the best. &Nbsp; >
The culture soil, which is composed of leaves and weeds of various plants mixed into garden soil, water and human excrement and urine, is acid after accumulation, fermentation and maturity. It shall be used after being exposed to the sun and sieved.
This is a kind of natural humus with loose and acidic soil. Compared with Heishan mud, Huangshan mud has more viscous texture and less humus. It is often used as the main culture material of Camellia, orchid, Rhododendron and other acid loving flowers. &Nbsp; >
It can improve the physical structure of the soil and increase the drainage ventilation of the soil. It can be used as a material for preparing culture soil, and also as a cutting or sowing substrate. When sea sand is used as culture soil, it must be washed with fresh water, otherwise the salt content is too high, which will affect the growth of flowers. &Nbsp; >
The ash of rice straw or other weeds, rich in potassium fertilizer. Add to the culture soil to make it well drained, loose, and increase the content of potassium fertilizer, slightly alkaline.
It is a kind of fertilizer powder made by grinding and fermenting animal bones, which contains a lot of phosphate fertilizer.
It has all the soil conditions required for potted flowers: loose and aerated, good water retention and permeability, strong heat preservation, reducing the temperature difference in the basin in the day and night, light weight, clean and sanitary. It is neutral and slightly acidic. When used alone, the plant cannot be fixed, and it is often mixed with other materials.
Under the larch tree, there is a layer of fallen leaves in autumn and winter every year. The leaves of larch are small, flat, light, soft and easy to crush. After a period of accumulation, this kind of fallen leaves can be used as materials for preparation and culture, especially for azalea. &Nbsp; >
Collect the fallen leaves and topsoil under the larch, pile up for 1-2 winter, remove the stones and residual branches after screening, and pay attention to compaction when using.
Larch leaves can also be used as a culture material for the preparation of acidity, microacidity and the improvement of porosity and permeability.
