Production method of talc tailing charred nutrient soil

Abstract

The invention discloses a production method of talc tailing charred nutrient soil. The key point of the technical scheme of the invention is that materials for talc tailing charred soil is stirred and extruded into tabular grains; the grains are charred into talc tailing charred soil; materials for talc tailing charred nutrient soil are granulated and sterilized; and packaging is carried out, such that talc tailing charred nutrient soil is obtained. The talc tailing charred nutrient soil is composed of talc tailing, activated white clay slag, peat, attapulgite clay, bentonite, zeolite, waste, vermiculite, diammonium phosphate, perlite, superabsorbent resin and ferrous sulfate. The talc tailing charred nutrient soil contains large amounts of nitrogen, phosphorous, potassium, organic matters and trace elements, and is high-quality, nontoxic, sterile, harmless and odorless nutrient soil with complete nutrients, high fertilizer effect and good water retention performance. The talc tailing charred nutrient soil is suitable to be used for planting flowers and seedlings. The production method of the talc tailing charred nutrient soil is suitable for producing charred nutrient soil and nutrient substrate.

Description

technical field [0001] The invention relates to nutrient soil, in particular to a production method of talc tailings carbonized nutrient soil. Background technique [0002] Most of the nutrient soil raw materials used by existing flower seedlings are mixed with materials such as mountain mud, garden soil, pond mud, peat soil, river sand, plant ash, wood chips, crop straw, fungus cultivation waste and humus. The soil has not undergone reasonable ingredients, disinfection and sterilization, poor water and fertilizer retention, poor air permeability, and easy compaction. The mineral nutrients in the nutrient soil are difficult to be absorbed by flower seedlings, and flower seedlings are also affected by viruses and bacteria in the soil. and newly sprouted weeds are not conducive to the normal growth and development of flower seedlings. [0003] Both phosphorus and potassium are essential nutrients for the growth of flower seedlings. Although the nutrient soil contains a certai...

Problems solved by technology

[0002] Most of the nutrient soil raw materials used by existing flower seedlings are mixed with materials such as mountain mud, garden soil, pond mud, peat soil, river sand, plant ash, wood chips, crop straw, fungus cultivation waste and humus. The soil has not undergone reasonable ingredients, disinfection and sterilization, poor water and fertilizer retention, poor air permeability, and easy compaction. The mineral nutrients in the nutrient soil are difficult to be absorbed by flower seedlings, and flower seedlings are also affected by viruses and bacteria in the soil. and newly germinated weeds, which is not conducive to the normal growth and development of flower seedlings

[0003] Both phosphorus and potassium are essential nutrients for the growth of flower seedlings. Although the nutrient soil contains a certain amount of phosphorus and potassium, most of them are slow-acting phosphorus and potassium, which cannot be directly absorbed by the roots of flower seedlings, resulting in slow growth of flower seedlings. , affect the normal growth and development of flower seedlings, therefore, the phosphorus and potassium in the nutrient soil need to be converted into soluble available phosphorus and potassium before they can be directly absorbed and utilized by plants

[0004] 80% of my country's mineral resources are associated mines. A large amount of valuable phosphorus, potassium and trace elements are stored in the tailings. The stockpiling of tailings requires a large amount of land. There is a great potential safety hazard in the tailings stockpile, which poses a serious threat to the property and life safety of the people in the surrounding areas.
