Production method for lime residue carbonization nutrition soil

Abstract

The invention discloses a production method for lime residue carbonization nutrition soil. The main points of the technical scheme are that firstly, ingredients of lime residue carbonization soil are stirred and extruded into sheet-shaped particles, the sheet-shaped particles are subjected to carbonizing treatment and lime residue carbonization soil is obtained. Then the ingredients of lime residue carbonization nutrition soil are subjected to granulation and disinfection, and packaging into lime residue carbonization nutrition soil is carried out. The lime residue carbonization nutrition soil is composed of lime residues, activated clay waste residues, peat, attapulgite, bentonite, zeolite, crushed waste, waste after water retting, vermiculite, diammonium phosphate, perlite, ferrous sulphate and super-absorbent resins. The lime residue carbonization nutrition soil contains a lot of nitrogen, phosphor, potassium, organic matters and trace elements, and is a nontoxic, aseptic, harmless high-quality nutrition soil with complete nutrition ingredients, high fertilizer efficiency, no foul smell and good water retention performance. The lime residue carbonization nutrition soil is suitable for planting flowers and nursery stocks, and the production method is suitable for producing carbonization nutrition soil and nutrition matrixes.

Description

Technical field [0001] The invention relates to nutrient soil, in particular to a production method of lime residue carbonized nutrient soil. Background technique [0002] Most of the nutrient soil raw materials used in flower seedlings are mixed and prepared from landslide, garden soil, pond mud, peat soil, river sand, plant ash, wood chips, crop straw, fungus cultivation waste, humus and other materials. These nutrients The soil has not undergone reasonable ingredients and disinfection. It has poor water and fertilizer retention capacity, poor air permeability, and is easy to compact. The mineral nutrients in the nutrient soil are difficult to be absorbed by flower seedlings, and flower seedlings will also be affected by viruses and bacteria in the soil. And the infringement of newly germinated weeds is not conducive to the normal growth and development of flowers and seedlings. [0003] Both phosphorus and potassium are essential nutrients for the growth of flower and seedlings...

AI Technical Summary

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] During the production of lime paste, a large amount of lime residue will be produced. Since the lime residue and leachate are strongly alkaline, long-term accumulation not only occupies a large amount of land, but also has a serious erosion effect on the land, causing serious environmental pollution. In the lime production plant There is a large amount of lime residue around the construction site, which has not been well developed and utilized
