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 talc tailings compressed nutrient soil: (1) Input the ingredients of talc tailings compressed nutrient soil into the running mixer for stirring, and after stirring evenly, input it into a tablet machine to compress into talc tailings compressed nutrient soil flakes, talc The thickness of the tailings compressed nutrient soil flakes is controlled at 16mm; (2) The talc tailings compressed nutrient soil flakes are transported to a microwave belt type drying and sterilizing machine for low-temperature sterilization and drying, and the temperature is controlled at 70-90°C , the time is controlled at 40 minutes, and the water content of the talc tailings compressed nutrient soil flakes after sterilization and drying is ≤15%; In the bacteria bank, use the waste heat in the talc tailings compressed nutrient soil sheet to continue to sterilize and dry, and t...

Abstract
The invention discloses a method for producing talc tailing compressed nutrient soil. According to the technical scheme, the method comprises the following steps: firstly, acidifying talc tailings and sludge, further stirring, compressing and sterilizing components of the talc tailing compressed nutrient soil in microwave at low temperature, and subsequently packaging to obtain a finished product. The talc tailing compressed nutrient soil consists of materials such as acidified talc tailings, acidified sludge, instant sodium silicate, polyvinyl alcohol, ferrous sulfate, peat, flower ceramsite, high-viscosity attapulgite clay, biogas slurry, biogas residue, crushed plant fiber, expanded perlite and high water absorbing resins. The talc tailing compressed nutrient soil contains a great amount of nitrogen, phosphorus, potassium, organic matters and multiple microelements, can provide nutrient elements which are necessary for plants to grow, can reduce damage to plants caused by pathogenic bacteria and insects, is beneficial for normal growth and development of plants and can preserve the ecological environment, and the method for producing the talc tailing compressed nutrient soil is applicable to production of talc tailing compressed nutrient soil of various different formulas.
Description
technical field [0001] The invention relates to nutrient soil, in particular to a production method of talc tailings compressed nutrient soil. Background technique [0002] Talc is a hydrothermally altered mineral. Magnesium-rich minerals are often transformed into talc by hydrothermal alteration, so talc often presents mineral false appearances such as olivine, enstatite, amphibole, tremolite, etc. Talc is a common silicate mineral, which is very soft And it has a greasy feel; talc is generally blocky, leafy, fibrous or radial, and the color is white or off-white, and it will have various colors due to other impurities. [0003] Talc tailings is a kind of tailings containing more impurities after talc beneficiation. [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...
