What kind of soil to use for planting trees, and what soil is best for planting flowers

1. Yellow-brown soil.

Yellow-brown soil has the characteristics of aluminization of yellow soil and red soil, and also has the characteristics of viscosity of brown soil. It has a weak acidic reaction and has a relatively high natural fertility.

2. Brown soil. The degree of leaching of brown soil is not very strong, and there is a small amount of calcium carbonate deposit. The soil showed neutral and slightly alkaline reactions, with more accumulation of minerals and organic matter, thicker humus layer and higher fertility.

3. Chernozem.

Chernozem has the most abundant humus content, the thickness of the humus layer is large, the soil color is mainly black, showing a neutral to slightly alkaline reaction, calcium, magnesium, potassium, sodium and other inorganic nutrients are also more, and the soil fertility is high.

According to the light of the weight, it is perlite, but it is too light, and the tree will be blown by the wind. Mix the soil with a certain percentage of perlite. It also depends on what kind of trees are planted and what kind of soil quality you like.

If it is a seedling.

Nutrient soil can be used.

Nutrient soil is specially formulated to meet the growth and development of seedlings, containing a variety of mineral nutrients, loose aeration, strong water and fertilizer retention ability, and no pests and diseases. Nutrient soil is generally prepared by mixing fertile field soil with rotting manure. However, the nutrient soil sold on the market generally does not contain much nitrogen, phosphorus and potassium, and can be planted directly, and reasonable fertilization is required in the later stage.

It is best to use humus soil for planting flowers.

Soil is very important for raising flowers, and the nutrients of flowers basically come from the soil, so it is recommended to use humus, and mix some furnace ash, coarse sand, etc. Humus, also known as humus, is a nutrient soil formed by microbial decomposition and fermentation of plant branches and leaves in the soil. In this process, in which the branches and leaves of plants are decomposed by the alternating activities of a variety of microorganisms, many advantages are formed that are different from those of natural soil.

The humus can generally be dug in the forest on the mountain, the humus is looser in appearance, dark in color, not easy to accumulate water, if there are conditions, you can also cultivate humus, the leaves, weeds, small branches, etc. are piled up in a large bucket and buckled on the ground, about 3 months.

How to make humus:

In autumn, the fallen leaves of the broad-leaved trees are collected and filled in the dug pit and stepped on with your feet. When the fallen leaves filled in the pit are about 10 cm from the surface, pour water into the pit just below the fallen leaves. Wait until most of the water has seeped into the ground, then cover the fallen leaves with soil and then cover the pit with a plastic film.

In the spring of the following year, the rotten leaves are dug out of the pit and overturned every few days, so that they can be weathered and sifted to become humus. This soil has good air permeability, strong water retention, acidic reaction, does not contain limestone, and has long-lasting fertility.

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.

When potted flowers, they are generally selected pastoral soil, humus soil, peat soil, sandy loam soil, etc., and the plants cultured in pots need to have enough soil porosity, good ventilation, and sufficient nutrition to promote growth, and every 1-2 years of cultivation, it is best to replace the new soil for maintenance.

Pastoral soil is a very common soil and can generally be obtained in vegetable gardens. This soil has high fertility, good aggregate structure and rich humus. However, there are some disadvantages, such as the surface layer is easy to compact when dry, and the aeration and permeability are poor when wet, so it cannot be used as a separate soil.

Most of the humus soil is formed directly in the mountains and forests after many years of weathering, so it is also relatively easy to obtain. This kind of soil has a loose texture, permeable and breathable, retains water and fertilizer, is rich in organic matter and a small amount of nutrients, which can promote the good growth of potted plants.

Peat soil often exists in some lakes and rivers, mountain plains, and mountain valleys, and it is mainly due to long-term water accumulation and insufficient decomposition in the absence of oxygen to form soil. This soil is rich in organic matter and minerals, which can meet the needs of the plants.

Sandy loam is composed of clay, silt and sand particles, of which the sand content accounts for 80% and clay accounts for 20%. This soil is lightweight, high in nutrient content, aerative and permeable, and not sticky or hard. It is determined that the fertilizer and water retention are relatively poor, and it is more suitable for farming.
