Embodiment 1

[0024] Take 2L of expanded perlite with a particle size of 2mm, 0.8L of organic fertilizer with a particle size of 1mm, and 0.1L of cement with a particle size of 0.01mm, mix and stir evenly to obtain a mixture, and add the mixture to the disc granulator In the process, water is sprayed to bind and granulate to obtain granules, which are then dried to obtain artificial soil aggregates.

Embodiment 2

[0026] Take 1L of ceramsite sand with a particle size of 0.1mm, 0.4L of organic fertilizer with a particle size of 0.5mm, and 0.1L of cement with a particle size of 0.05mm, mix and stir evenly to obtain a mixture, and add the mixture to the round In the pan granulator, water is sprayed to bind and granulate to obtain granules, which are then dried to obtain artificial soil aggregates.

Embodiment 3

[0028] Take 1L of volcanic sand with a particle size of 1mm, 0.2L of organic fertilizer with a particle size of 0.1mm, 0.2L of coconut peat with a particle size of 0.1mm, and 0.1L of kaolin with a particle size of 0.01mm, mix and stir evenly to obtain a mixture , adding the mixture into a disc granulator, spraying water to bond and granulate to obtain granules, and drying them to obtain artificial soil aggregates.

Abstract

The invention discloses artificial soil granular aggregates and a preparation method therefor. The artificial soil granular aggregates are prepared from artificial soil granules through granulation. The artificial soil granules comprise inorganic substances, organic substances and binders. Inorganic substances, organic substances and binders are taken and mixed uniformly, and a mixture is obtained. The mixture is added into a granulator. Water is sprayed and granulation is carried out. Water evaporation is carried out and the artificial soil granular aggregates are prepared and obtained. The artificial soil granular aggregates have soil granule structures, and can replace soil as a plant culture medium. Medium loss is not easy during the irrigation process, contradiction of consumption and accumulation of medium nutrients can be coordinated, the culture medium temperature can be adjusted, and growth and extension conditions of plant roots can be improved. In addition, the artificial soil granular aggregates can be used for rainwater recovery as a filtering medium.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to an artificial soil aggregate and a preparation method thereof. Background technique [0002] Soil is a layer of loose material on the surface of the earth, composed of various granular minerals, organic matter, water, air, microorganisms, etc. Among all soil types, aggregate structure is the most suitable structure soil type for plant growth, and it marks the level of soil fertility and utilization value to a certain extent. The so-called soil aggregate, that is, the soil aggregate structure, is a soil structure formed by bonding together several soil single particles, and its particle size is 0.25-10mm. Small pores are formed between single particles and large pores are formed between aggregates, so compared with the single particle structure, the total porosity is larger. The small pores in the soil aggregates can retain water, and the large pores can maintain venti...
