摘要：

The method that the present invention describes the plant growth medium based on polyvinyl formal and prepares it. Plant growth medium based on the polyvinyl formal be used alone or with known plant growth substrate (medium). The hydrophilic porous bulk material of plant growth medium based on the polyvinyl formal, aperture are 5-500 μm, 100 μm of average pore. Mixing, plant growth medium is particle or powder. Homogeneous plant growth substrate is mixed, it can be used as loose particle, and the particle of extrusion is for the material of volume or as synthesis final product (form being minimally machined).
