Horticultural perlite is a kind of white granular material with honeycomb structure, which is made from perlite ore after preheating, instantaneous high temperature roasting and expansion. Its principle is: Perlite ore is crushed to form a certain size of ore, which is preheated, roasted and rapidly heated (above 1000 ℃), water in the ore vaporizes, and expands in the softened ore containing glass to form a porous structure, Non metallic mineral products with volume expansion of 10-30 times

Application principle

Using the porous characteristics of perlite, the characteristics of perlite can help the roots of crops go deep into the perlite matrix to absorb nutrients. The pores of perlite can save a lot of water and nutrients, and supply the growth needs of crops for a long time. In agricultural production, it can be directly used for planting a large number of crops on the surface, and it can also be used for breeding flowers and plants in flowerpots, The porous adsorption of perlite can also be used as diluent and carrier of insecticide and herbicide in agriculture
