Yellowish Brown Rock Wool Sheets 1200x600mm For Agriculture

Rock Wool Boards With Good Performance And Multiple Applications In Agriculture 

Rock wool boards, due to their unique physical properties (such as high porosity, insulation properties, and sterility), are widely used in the agricultural field and have significant advantages over traditional materials.

Substrate for Soilless Culture

Rock wool has excellent air permeability and water retention. Refined at high temperatures, it is sterile and pollution-free, making it a major substrate for soilless culture in Europe. Agricultural rock wool is made from approximately 60% basalt, 20% coke, and 20% limestone through processes such as high-temperature melting and fiber drawing. It has a high porosity, with 3% of its volume being fibers and 97% being pores, which is conducive to the extension and growth of plant roots. It can be made into different forms such as rock wool plugs, rock wool blocks, and rock wool strips to meet the needs of different stages from seed breeding, seedling raising to crop growth.

Improving Soil Environment

In potted planting mode, burying rock wool in the soil can effectively enhance the soil's water storage and retention capacity. For example, in tomato pot experiments, burying block-shaped rock wool under the roots or sheet-shaped rock wool around the roots can significantly increase the volumetric water content of the soil, alleviate the adverse effects of water stress on the growth and physiological characteristics of potted plants, and promote the rooting and growth of plant roots.

Thermal Insulation for Greenhouses

Rock wool boards have excellent thermal insulation performance. Their interior is filled with tiny pores, which can effectively prevent heat conduction, with a thermal conductivity as low as 0.036 W/(m·K). When rock wool boards are used as thermal insulation materials in the construction of greenhouses, compared with traditional covering methods such as straw curtains and plastic films, they can not only better maintain the temperature inside the greenhouse but also effectively prevent disease problems caused by water condensation, creating a suitable growth environment for crops.

Reducing the Occurrence of Diseases and Pests

Rock wool substrate is an inorganic substrate that does not carry any harmful organisms such as pathogenic bacteria and insect eggs. This can greatly reduce the cost of preventing and controlling soil-borne diseases and pests, and lower the management and production expenses during use. At the same time, the device for rock wool culture is simple, easy to install and use. Moreover, due to the uniform texture of rock wool, the supply of nutrient solution and oxygen at different positions in the cultivation bed is similar, which is beneficial to balanced yield increase and reduces the occurrence of diseases and pests caused by environmental differences.

In summary, rock wool boards are not only functional materials in agriculture but also help address pain points such as "disease and pest control, thermal insulation and energy conservation, and water/fertilizer waste," driving the transformation of agricultural production toward high efficiency, green development, and standardization.
