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

Embodiment Construction
[0063] Below in conjunction with embodiment the present invention will be further described:
[0064] 1. The production method of pyrophyllite tailings compressed nutrient soil: (1) Input the ingredients of pyrophyllite tailings compressed nutrient soil into the running mixer for stirring, and after stirring evenly, input it into the tablet press to compress into pyrophyllite tailings compressed nutrient soil flakes The thickness of the pyrophyllite tailings compressed nutrient soil flakes is controlled at 18 mm; (2) the pyrophyllite tailings compressed nutrient soil flakes are transported to a microwave belt drying and sterilizing machine for low-temperature sterilization and drying, and the temperature is controlled At 70-90°C, the time is controlled at 35 minutes, and the water content of the sterilized and dried pyrophyllite tailings compressed nutrient soil sheet is ≤15%; (3) the sterilized and dried pyrophyllite tailings compressed nutrient soil sheet The material is tra...

Abstract
The invention discloses a production method of pyrophyllite tailing compressed nutrient soil. According to the technical scheme, the production method is characterized by comprising the steps of firstly, acidizing pyrophyllite tailings and sludge; then, stirring ingredients of the pyrophyllite tailing compressed nutrient soil, compressing, carrying out low-temperature microwave sterilization, and then, packaging to obtain a finished product. The pyrophyllite tailing compressed nutrient soil is composed of materials such as acidized pyrophyllite tailings, acidized sludge, polyvinyl alcohol, ferrous sulfate, peat, flower ceramsites, high-viscosity attapulgite clay, biogas slurry, smashed plant fiber, expanded vermiculite, expanded perlite, super absorbent resin and the like. The pyrophyllite tailing compressed nutrient soil contains a great number of nitrogen, phosphorus, potassium, organic matters and various trace elements, is capable of providing various nutrient elements necessary for growth of plants and reducing hazards of pathogenic bacteria and pests to the plants and is beneficial to the normal growth and development of the plants and the protection of the ecological environment. The production method of the pyrophyllite tailing compressed nutrient soil is suitable for producing the pyrophyllite tailing compressed nutrient soil according to different formulas.
Description
technical field [0001] The invention relates to nutrient soil, in particular to a production method of pyrophyllite tailings compressed nutrient soil. Background technique [0002] Pyrophyllite is a kind of clay mineral. The ore is mainly massive, but also earthy and fibrous. Pyrophyllite is often combined with quartz, kaolinite, montmorillonite, dickite, sericite, kyanite, red Pillars, corundum and other minerals are symbiotic. [0003] There are a large number of pyrophyllite tailings in the pyrophyllite mining area, which have not been well developed and utilized. [0004] 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. ...
