    Detailed Product Description
    Type: Expanded Raw Material: Vermiculite
    State: Powder Or Granular

    Expanded meteorite
    Vermiculite is a hydrate that is in the form of a block or a sheet. The water molecules in the interlayer are burned at a high temperature, and the volume is increased by 6-15 times. Rich in nitrogen, phosphorus, potassium, aluminum, iron, magnesium, silicate and other ingredients. Vermiculite has a higher number of layer charges, so it has a higher cation exchange capacity and a stronger cation exchange adsorption capacity. The characteristics are: light weight, good water and fertilizer adsorption performance, no decay, can be used for 3-5 years (unlike humus, coconut shell and other perishable).
    The raw ore raw ore is calcined at a high temperature and becomes an expanded vermiculite. Conventional particle size specifications for expanded vermiculite are 0.5-1 mm, 1-3 mm 2-4 mm, 3-6 mm, 4-8 mm, 1-6 mm, and the like. In addition, other particle size models can be produced according to customer's production needs. The vermiculite powder is calcined from the raw gemstone ore by high temperature, screened, and ground into a powder.
     

     

    Vermiculite is rich in nitrogen, phosphorus, potassium, aluminum, iron, magnesium, silicate and other components. Vermiculite has a higher number of layer charges, so it has a higher cation exchange capacity and a stronger cation exchange adsorption capacity. The characteristics are: light weight, good water and fertilizer adsorption performance, no decay, can be used for 3-5 years (not like humus, coconut shell clothes and other perishable). The horticultural vermiculite is a specially processed expanded vermiculite whose main function is to increase the aeration and water retention of the soil (medium). Because of its fragility, as the use time is prolonged, the medium is easily densified and loses air permeability and water retention, so the coarse vermiculite is longer than the fine use time, and the effect is good. Therefore, the horticultural vermiculite should be selected from coarse flaky vermiculite, even if the seeding medium of the fine seeds and the covering as the seeding are thicker.
    The weight of horticultural meteorites is 130-180 kg/m3, which is neutral to alkaline (ph7-9). Each cubic meter of vermiculite can absorb 500-650 liters of water. After steam sterilization, it can release appropriate amount of potassium, calcium and magnesium.
    As a horticultural vermiculite, its main function is to increase the aeration and water retention of the soil (medium). Because of its fragility, as the use time is prolonged, the medium is easily densified and loses air permeability and water retention, so the coarse vermiculite is longer than the fine use time, and the effect is good.

     

    In horticulture, vermiculite can be used for flowers, vegetables, fruit cultivation, and nursery. In addition to potting soil and conditioner, it is also used for soilless cultivation. As a nutrient base for planting potted trees and commercial seedbeds, it is particularly advantageous for planting and transporting plants. Vermiculite can effectively promote the growth of plant roots and the stable development of seedlings. It provides the water and nutrients necessary for plant growth for a long time and keeps the temperature of the roots stable. Vermiculite can make crops get enough water and minerals from the beginning of growth to promote faster plant growth and increase yield.
