Multifunction soil conditioner and preparation method thereof

Abstract

The invention provides a multifunction soil conditioner and a preparation method thereof. The soil conditioner belongs to the soil conditioning and stabilizing materials. The invention in particular relates to the multifunction soil conditioner prepared with the industrial waste residues as the main raw materials. The multifunction soil conditioner is characterized by comprising the following raw material components in dry-basis parts by weight: 15-80 parts of phosphogypsum, 5-60 parts of fly ash and 2-40 parts of phosphate rock powder. The multifunction soil conditioner uses the industrial waste residues including phosphogypsum and fly ash as the main raw materials, changes wastes into valuables, has good adaptability to soil, is suitable for various soil, is convenient to use, low in cost and ideal and has the functions of applying and increasing fertilizers, slow releasing and fixing nitrogen, conserving water and soil, regulating acid and base and inhibiting bacteria and preventing diseases. All the components of the multifunction soil conditioner are accepted by the soil. The preparation method is characterized in that the equipment investment is saved, the preparation process is simple and the manufacturing cost is low.

Description

technical field [0001] The invention is a multifunctional soil conditioner and a preparation method thereof. It belongs to soil conditioning and stabilizing materials. It particularly relates to a multifunctional soil conditioner made from industrial waste residues as the main raw material. Background technique [0002] Almost all the water and nutrients needed for the growth of land plants come from the soil. Therefore, the high quality, stable yield and high yield of agricultural products depend on a good soil environment. The impact of different regional climates and environments, the excessive discharge of industrial wastes, the disorderly addition of chemical fertilizers, the deterioration of soil physical structure and chemical properties, the imbalance of nutrients, the lack of trace elements, the deficiency of beneficial microbial flora, the invasion of pathogens, etc. will have a negative impact on the soil environment. [0003] In the prior art, although variou...
