Mobile: 18032023929 QQ: 805221314 Manager Fan Vermiculite is a silicate material mica-like material formed by high temperature heating. Its rapid loss of moisture during heating and expansion, the expanded volume equivalent to 8-20 times the original volume. So that the substance increases the aeration porosity and water-holding capacity. Horticultural vermiculite density from 130 to 180 kg / cubic meter, neutral to alkaline (ph7-9). Per cubic meter of vermiculite can absorb 500-650 liters of water. After steam sterilization can release the right amount of potassium, calcium and magnesium. As a horticultural vermiculite, whose main role is to increase the soil (media) aeration and water retention. Because of their fragile, with the use of time, easy to make medium density and lose aeration and water retention, so long thick vermiculite use than the fine time, and good results. Therefore, horticultural vermiculite should choose thick flaky vermiculite, even tiny seeds sown media and as mulch seeding, are to thick for good. Purpose: One of the main material 1. planting medium can be used mixed with peat, perlite. 2. sowing cover. 3. The appropriate medium pH is adjusted. Growing Media absorbent vermiculite cation exchange properties and chemical composition, it plays a fertilizer, vermiculite can be used for flowers, vegetables, fruit cultivation, breeding and other aspects. Except for potting soil and regulators, but also for soilless cultivation. As planting potted trees and grass nutrition business seedbed for transplanting plants and transport in particular.

A long time to provide moisture and nutrients necessary for plant growth, and can maintain a stable root sunshine temperatures. Vermiculite can crop can get enough water and minerals from the early growth, and promote rapid plant growth, increase yield. Storage, ventilation and mineral fertilizers multiple roles.
