Application and main function of horticultural perlite

Addtime:2021-05-17   Views:49

In the process of perlite formation, due to the different geographical external environment and internal structure of perlite ore, the color of perlite is different, resulting in different uses. Some are used in construction industry, some are used as filter aid and filler, some are used in agriculture, forestry and horticulture, some are used in machinery, metallurgy, hydropower and light industry. At present, the perlite produced by Shandong Yuanrun Ecological Agriculture Co., Ltd. is not only used in urban greening, gardening nursery, lawn construction, tree transplanting, roof garden, underground parking lot, ecological road and bridge, Sunshine Hall, courtyard potted plants, playground and saline alkali land improvement, but also widely used in soilless cultivation of flowers and economic plants, It is a good plant material for ecological horticulture.


Why perlite can be so favored and used in agriculture, horticulture and cultivation is determined by its unique physical characteristics. What are the physical properties?


Characteristics of horticultural perlite:

1. The effective water content is as high as 45%, which can effectively intercept rainwater.

2. The weight of saturated water absorption is 450-600kg / m3 (about 1800kg / m3 for general soil), which effectively solves the load problem of building structure.

3. 100% pure inorganic culture medium, stable physical and chemical indexes, long-term cultivation of plants without changing soil.

4. The permeability coefficient is 200 mm / HR, which can effectively avoid the harm of sedimentation.

5. It is clean without peculiar smell, simple in construction and convenient in maintenance.

6. The porosity of the product greatly promotes the growth and development of the virtual root system of plants, has an excellent fixation effect on trees, and overcomes the damage of the main root of trees to the building structure.

The horticultural perlite produced by the company not only has the above conventional physical properties, but also has the following characteristics through the continuous research and development of technical experts: light weight, porous, heat insulation, incombustible, sound absorption, water resistance and corrosion resistance


The functions of horticultural perlite in Horticulture are as follows:

1. Loose the internal structure of the matrix to maintain the normal exchange of water, gas and fertilizer;
2. Reduce the bulk density, easy to transport and transplant; 3. Maintain the stable structure of the matrix.

Because of the porous characteristics of perlite, it is beneficial for the roots of crops to go deep into the perlite matrix to absorb nutrients. The pores of perlite can store a lot of water and nutrients, which can supply the growth needs of crops for a long time. In agricultural production, it can be directly used to plant a large number of crops on the surface, and can also be used to cultivate flowers and plants in flowerpots. At the same time, it plays an important role in soil improvement, soil hardening regulation, crop lodging prevention and fertilizer efficiency control. The porous adsorption of perlite can also be used as diluent and carrier of pesticides and herbicides in agriculture.
