Production method of medical stone tailings compressed nutrient soil

Abstract

The invention discloses a production method of medical stone tailing compressed nutritional soil, wherein the technical scheme disclosed by the invention is as follows: medical stone tailings and sludge are acidized at first; and then, mixtures of medical stone tailing compressed nutritional soil are stirred, compressed, sterilized at low temperature through microwaves, and packaged into finished goods. The medical stone tailing compressed nutritional soil disclosed by the invention is composed of the materials including acidized medical stone tailings, acidized sludge, polyvinyl alcohol, ferrous sulphate, peat, flower ceramsite, high-viscosity attapulgite, biogas slurry, crushed plant fibre, expanded vermiculite, expanded perlite, super absorbent resin and the like; the medical stone tailing compressed nutritional soil contains a lot of nitrogen, phosphorus, potassium, organic matters and a plurality of trace elements, and is capable of providing nutritional elements necessary for plant growth, reducing harm of pathogenic bacteria and pests to plants, being beneficial to normal growth and development of plants and protecting the ecological environment. The production method of the medical stone tailing compressed nutritional soil, disclosed by the invention, is suitable for producing medical stone tailing compressed nutritional soil of different formulae.

Description

technical field [0001] The invention relates to nutrient soil, in particular to a production method of compressed nutrient soil from medical stone tailings. Background technique [0002] Medical stone is a kind of volcanic rock, and its main mineral is volcanic rock. 50-75.5 million years ago, the lava erupted from the volcano was buried in the ground. After the high humidity and heat in the volcanic zone, these lavas were transformed into acidic substances, and then transformed into acidic substances by crustal changes. The effect of pressure produces medical stone, and it can be inferred that medical stone is produced in volcanic areas; medical stone is a compound mineral or medicinal rock that is non-toxic and harmless to organisms and has certain biological activity. , the main chemical composition of medical stone is inorganic aluminosilicate. [0003] There are a large number of medical stone tailings in the medical stone mining area, which have not been well develope...

AI Technical Summary

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

[0009] 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
