Method for producing kaolin compressed nutritional soil

Abstract

The invention discloses a method for producing kaolin compressed nutritional soil. According to the technical scheme, the method comprises the following steps: firstly, acidizing kaolin and sludge, further stirring the ingredients of the kaolin compressed nutritional soil, compressing, and sterilizing with microwaves at a low temperature, and finally packaging, thus obtaining a finished product, wherein the kaolin compressed nutritional soil consists of materials such as acidified kaolin, acidified sludge, instant sodium silicate, polyving alcohol, ferrous sulfate, peat, flower ceramsite, hyper-viscous attapulgite clay, biogas slurry, biogas residue, crushed plant fiber, expanded vermiculite, expanded perlite and high-water-absorption resin. As the kaolin compressed nutritional soil contains a great deal of nitrogen, phosphorus, potassium, organic matters and multiple microelements, can provide nutritional elements essential for plant growth, can reduce damage of pathogenic bacteria and injurious insects to plants, is good for normal growth and development of plants and protects the ecological environment; and the method for producing the kaolin compressed nutritional soil is applicable to production of kaolin compressed nutritional soil according to different formulas.

Description

technical field [0001] The invention relates to nutrient soil, in particular to a production method of kaolin compressed nutrient soil. Background technique [0002] Kaolin is a kind of clay and clay rock mainly composed of kaolinite clay minerals. It is mostly dull. When it is pure, it is white and fine. If it contains impurities, it can have gray, yellow, brown and other colors. The appearance can vary depending on the cause. It is loose soil block and compact rock block. [0003] Sludge is a kind of easily corrupt and smelly paste produced in the process of sewage treatment. It enriches the pollutants in sewage, contains a large amount of nutrients such as nitrogen and phosphorus, organic matter, virus microorganisms, parasite eggs, heavy metals, etc. Toxic and harmful substances will cause serious harm to the environment if they are not effectively treated and disposed of. [0004] The water content of the sludge produced by the urban sewage treatment plant is ≥80%, mo...

Problems solved by technology

Generally, it is prepared by mixing fertile field soil and decomposed manure. There are also nutrient soils selected from imported high-quality peat and coconut bran mixed in a specific proportion. However, these nutrient soils have not undergone reasonable ingredients and strict disinfection. Conducive to the normal growth and development of seedlings

[0008] Because the treated nutrient soil is relatively light and loose, the conventional product of nutrient soil is relatively large, which is not conducive to reducing the cost of production and transportation
