Horticultural vermiculite

There are two general specifications for horticultural vermiculite: 1-3mm (rearing vermiculite) and 2-4mm (Horticultural vermiculite for gardening), and can also produce various types of horticultural vermiculite according to customer's requirements. Vermiculite used in gardening is a specially developed vermiculite. Its main function is to increase the aeration and water holding capacity of soil (medium). Because of its fragility, with the extension of the use time, it is easy to make the medium tight and lose the aeration and water retention, so the coarse vermiculite is longer than the fine use, and the effect is good. Therefore, the coarser flake vermiculite should be selected for horticultural vermiculite, even as the sowing medium of the fine seeds and the mulch as sowing, it is better to be thicker.
1. horticultural vermiculite is a mica like substance formed by silicate material heated by high temperature. During the heating process, the water loses rapidly and expands, and the volume after expansion is 8-20 times that of the original volume. Thus, the aeration pore and water holding capacity of the material are increased.
2. the density of vermiculite used for gardening is 130-180 kg / cubic meter, which is neutral to alkaline (ph7-9). The vermiculite per cubic meter absorbs 500-650 liters of water. After being sterilized by steam, the amount of potassium, calcium and magnesium can be released.

4. use:
A., one of the main materials for planting media, can be used in combination with peat and perlite.
B. sowing cover.
C. appropriately regulates the pH value of the medium.
