Method for producing diatomite compressed nutrient soil

Abstract

The invention discloses a method for producing diatomite compressed nutrient soil. According to key points of the technical scheme, the method comprises the following steps: acidizing diatomite and sludge, stirring, compressing and performing low-temperature microwave sterilization on ingredients of the diatomite compressed nutrient soil, and packaging to obtain the finished product. The diatomite compressed nutrient soil consists of acidized diatomite, acidized sludge, instant sodium silicate, polyvinyl alcohol, ferrous sulfate, peat, flower ceramsite, high viscosity attapulgite clay, biogas slurry, biogas residue, crushed plant fibers, expanded vermiculite, expanded perlite, super absorbent resin and other materials. The diatomite compressed nutrient soil contains lots of nitrogen, phosphorus, potassium, organic matters and multiple trace elements, can provide necessary nutrient elements for plant growth and reduce harm of pathogenic bacteria and injurious insects to plants and contributes to normal plant growth and development, the ecological environment is protected, and the method for producing the diatomite compressed nutrient soil is suitable for producing diatomite compressed nutrient soil of different formulas.

Description

technical field [0001] The invention relates to nutrient soil, in particular to a production method of diatomite compressed nutrient soil. Background technique [0002] Diatomaceous earth is a kind of biogenic siliceous sedimentary rock, which is mainly composed of the remains of ancient diatoms. Since the formation of diatomite ore has gone through a long geological age, in addition to containing a large number of diatoms, it also contains many impurities Among them, quartz, hydromica, kaolinite, montmorillonite, iron minerals, carbonates, sulfates, volcanic ash and other mineral debris are common. [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 effecti...

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

[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
