What are the cultivation substrates? The function and price of various cultivation substrates

When we plant crops or plants and seedlings, we all pay attention to the requirements of the soil. Generally speaking, the more fertile the soil is, the better the vegetables are, so many people will use the cultivation substrate. What are the cultivation substrates? What is the specific function and price? Let's learn about it.

I. what are the cultivation substrates?

There are many kinds of cultivation substrates, including seedling substrate, nutrient soil, peat soil, humus soil, flower soil, waste edible mushroom stick, coconut bran, fungus stick (excluding bacteria), peat soil, saw chaff, planting soil, water moss, ceramsite, perlite, vermiculite, Luqing matrix, crystal mud, red jade soil, lotus seed shell, pond mud, wood cutting, deer marsh soil and so on.

Second, the function of cultivation substrate.

1. Vermiculite: contains more nutrients such as potassium, calcium and magnesium, which can be absorbed and utilized by crops. Strong ability to absorb water.

2. Perlite: perlite is formed by heating gray volcanic rocks (aluminosilicate) to 1000 °C. It has the advantages of small bulk density, 93% porosity, good air and water holding capacity.

3, sawdust: cheap, good structure, generally can be used continuously 2-6 stubble.

4. Peat soil: the common peat matrix needs mixed sand, vermiculite, perlite and other substrates. Peat is widely distributed in northern China and is formed by long-term natural accumulation and decomposition of plant stem and leaf residues.

5. Humus soil: humus soil contains humus, which can be slowly decomposed in the soil, releasing nitrogen and sulfur-based nutrients for plant absorption, while releasing carbon dioxide for plant photosynthesis.

6. Coconut bran: coconut bran is a kind of fiber powder of coconut shell and a pure natural organic medium. the processed coconut bran is very suitable for cultivating plants.

7. Nutritious soil: in order to meet the growth of seedlings, nutritious soil is specially prepared with a variety of mineral nutrients, which has the advantages of loose ventilation, water and fertilizer conservation, and no diseases and insect pests.

Third, the price of cultivation substrate

The seedling substrate of Yongding County, Longyan City, Fujian Province is 333 yuan / ton, this price comes from the wholesale price of Nongxun Network, the actual price is based on the place of origin.

The above is the introduction of the cultivation substrate, we in the daily planting process, in order to grow well, the substrate is essential, do you have anything to add about the cultivation substrate?
